spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and
the plywood pieces to reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.
INSTALLING THE SWITCH

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

8. Repeat step # 2 - # 7 to install the second
aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

INSTALLING THE DIHEDRAL BRACE
1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.
2. Using a ruler and a pen, locate and mark the
center line of the Aluminum dihedral brace.

JOINING THE WING HALVES
1. Mix a generous amount of 30 minute epoxy.
Working with only one wing half for now, apply
a thin layer of epoxy inside the carton dihedral
brace tube and to only half of the dihedral
brace. Make sure to cover the dihedral brace
around as well as the sides, and use enough
epoxy to fill any gaps.
2. Slide the dihedral brace into the carton tube up
to the center line. Remove any excess epoxy
before it dries using a paper towel and rubbing
alcohol. Allow the epoxy to cure before
proceeding.
3. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
4. Mix a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the exposed half
of the dihedral brace, the inside of the carton
dihedral brace tube and the entire surface of
both root ribs. Make sure to use enough epoxy
to fill any gaps.
5. Slide the two wing halves together and carefully
align them at the leading and trailing edges. Wipe
away any excess epoxy using a paper towel and
rubbing alcohol. Use masking tape to hold the
two wing halves in place until the epoxy cures.

nose gear wire, four nylon mounting straps eight
3*12mm Phillips head sheet metal screws, three
wheels, six wheel collars w/set screws, and one
nylon steering arm with set screw.
2. There are two hardwood landing gear blocks
with one precut channel in each block in the
bottom of the wing. Locate the two landing gear
blocks on the bottom of the wing and using a
modeling knife, remove the covering from over
the precut channels.
Remove the covering 7. Locate the nose gear wire. Slide the nose gear
wire up through the lower portion of the nose
gear block, then through the nylon steering
arm, then through the upper portion of the nose
gear block. The top of the nose gear wire
should be flush with the top of the nose gear
bracket.
8. With the nose gear wire straight, angle the nylon
steering arm about 300 forward of the fire-wall
and tighten the set screw. Angling the arm
forward like this will allow room for the arm to
move back for more adequate steering.
3. Test fit the two main gear wires into the
channels. When satisfied with the fit, secure the
wires in place using the four nylon straps and
eight 3*12mm sheet metal screws. If you look
closely at the wing surface surrounding the
channel for the wire, you will notice that there
are already four pilot holes drilled to
accommodate the screws for the straps. Mount
the straps at these locations.
4. Install two of the wheels onto the axles using
the four wheel collars and set screws provided.
The wheels should be centered on the axles
with a wheel collar on each side, holding them
in place. Tighten the set screws on the collars
to secure them in place.The wheels should
rotate freely. You should apply a small drop of
lock-Tite thread lock to each set screw to
prevent them from coming loose.
5. Remove the hatch cover from the bottom front
of the fuselage. Working with the preinstalled
nylon steering housing, position it so the end of
it is flush with the front of the firewall. When
satisfied with the fit, glue the housing to the
firewall from the inside of the fuselage using 5
Minute Epoxy.
6. The preinstalled wire steering pushrod has a
factory made Z-Bend on the front end of it.
Connect the nylon steering arm to this pushrod.
The pushrod should be installed in the
outermost hole in the steering arm.

HORIZONTAL STABILIZER INSTALLATION
PARTS REQUIRED
· (1) Horizontal stabilizer with Elevator halves.
1. Using a modeling knife, cut away the covering
from the fuselage for the stabilizer and remove it.
3. Check the fit of the horizontal stabilizer in its slot.
Make sure the horizontal stabilizer is square and
centered to the fuselage by taking measurements,
but don't glue anything yet.
4. With the horizontal stabilizer correctly aligned,
mark the shape of the fuselage on the top and
bottom of the tail plane using a water soluble /
non-permanent felt-tip pen.
5. Remove the stabilizer. Using the lines you just
drew as a guide, carefully remove the covering
from between them using a modeling knife.
When cutting through the covering to remove it,
cut with only enough pressure to only cut
through the covering it's self. Cutting into the
balsa structure may weaken it. This could lead
to possible failure during flight.
2. Draw a center line onto the horizontal stabilizer.
4. Plug the aileron servo into the receiver and center
the servo. Install the servo arm onto the servo.
The servo arm should be perpendicular to the

spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and
the plywood pieces to reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

!
BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

5. Place the servo into the servo tray. Center the
servo within the tray and drill 1,6mm pilot holes
through the block of wood for each of the four
mounting screws provided with the servo.
6. Using the thread as a guide and using masking
tape, tape the servo lead to the end of the
thread: carefully pull the thread out. When you
have pulled the servo lead out, remove the
masking tape and the servo lead from the
thread.
7. Place the aileron servo tray / hatch into the
servo box on the bottom of the wing and drill
1,6mm pilot holes through the tray and the
servo box for each of the four mounting screws.
Secure the servo tray in place using the

8. Repeat step # 2 - # 7 to install the second
aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

INSTALLING THE DIHEDRAL BRACE
1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.
2. Using a ruler and a pen, locate and mark the
center line of the Aluminum dihedral brace.

JOINING THE WING HALVES
1. Mix a generous amount of 30 minute epoxy.
Working with only one wing half for now, apply
a thin layer of epoxy inside the carton dihedral
brace tube and to only half of the dihedral
brace. Make sure to cover the dihedral brace
around as well as the sides, and use enough
epoxy to fill any gaps.
2. Slide the dihedral brace into the carton tube up
to the center line. Remove any excess epoxy
before it dries using a paper towel and rubbing
alcohol. Allow the epoxy to cure before
proceeding.
3. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
4. Mix a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the exposed half
of the dihedral brace, the inside of the carton
dihedral brace tube and the entire surface of
both root ribs. Make sure to use enough epoxy
to fill any gaps.
5. Slide the two wing halves together and carefully
align them at the leading and trailing edges. Wipe
away any excess epoxy using a paper towel and
rubbing alcohol. Use masking tape to hold the
two wing halves in place until the epoxy cures.
6. When the epoxy has fully cured, double check
the center section joint. If any gaps are present,
mix a small amount of 30 minute epoxy and
carefully fill any remaining gaps. Remove the
excess epoxy using a paper towel and rubbing
alcohol. Allow the epoxy to fully cure before
proceeding.

correctly, mix up a generous amount of 30
minute epoxy. Apply a thin layer to the top and
bottom of the stabilizer mounting area and to the
stabilizer mounting platform sides in the
fuselage. Slide the stabilizer in place and
re-align. Double check all of your measurements
one more time before the epoxy cures. Remove
any excess epoxy using a paper towel and
rubbing alcohol and hold the stabilizer in place
with T-pins or masking tape.
2. Slide the vertical stabilizer into the slot in the
mounting platform in the top of the fuselage. Mark
the shape of the fuselage on the left and right
sides of the vertical stabilizer using a felt-tip pen.
3. Now, remove the vertical stabilizer and using
a modeling knife, carefully cut just inside the
marked lines and remove the film on both sides
of the vertical stabilizer. Just as you did with the
horizontal stabilizer, make sure you only press
hard enough to cut the film, not the balsa
vertical stabilizer.
4. Slide the vertical stabilizer back in place. Using
a triangle, check to ensure that the vertical
stabilizer is aligned 90 degree to the horizontal
stabilizer.
5. When you are sure that everything is a aligned
correctly, mix up a generous amount of 30
minute epoxy. Apply a thin layer to the slot in
the mounting platform and to the vertical
stabilizer mounting area. Apply epoxy to the
lower rudder hinge. Set the stabilizer in place
and re-align. Double check all of your
measurements once more before the epoxy
cures. Remove any excess epoxy using a

INSTALLING THE SPINNER
Install the spinner back-plate, propeller and
spinner cone. The spinner cone is held in place
using two 3mm x 20mm wood screws.
The propeller should not touch any part of the
spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and
the plywood pieces to reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.
INSTALLING THE SWITCH

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

!
BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

forward like this will allow room for the arm to
move back for more adequate steering.
3. Test fit the two main gear wires into the
channels. When satisfied with the fit, secure the
wires in place using the four nylon straps and
eight 3*12mm sheet metal screws. If you look
closely at the wing surface surrounding the
channel for the wire, you will notice that there
are already four pilot holes drilled to
accommodate the screws for the straps. Mount
the straps at these locations.
4. Install two of the wheels onto the axles using
the four wheel collars and set screws provided.
The wheels should be centered on the axles
with a wheel collar on each side, holding them

spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and
the plywood pieces to reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.
INSTALLING THE SWITCH

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

8. Repeat step # 2 - # 7 to install the second
aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

INSTALLING THE DIHEDRAL BRACE
1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.
2. Using a ruler and a pen, locate and mark the
center line of the Aluminum dihedral brace.

JOINING THE WING HALVES
1. Mix a generous amount of 30 minute epoxy.
Working with only one wing half for now, apply
a thin layer of epoxy inside the carton dihedral
brace tube and to only half of the dihedral
brace. Make sure to cover the dihedral brace
around as well as the sides, and use enough
epoxy to fill any gaps.
2. Slide the dihedral brace into the carton tube up
to the center line. Remove any excess epoxy
before it dries using a paper towel and rubbing
alcohol. Allow the epoxy to cure before
proceeding.
3. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
4. Mix a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the exposed half
of the dihedral brace, the inside of the carton
dihedral brace tube and the entire surface of
both root ribs. Make sure to use enough epoxy
to fill any gaps.
5. Slide the two wing halves together and carefully
align them at the leading and trailing edges. Wipe
away any excess epoxy using a paper towel and
rubbing alcohol. Use masking tape to hold the
two wing halves in place until the epoxy cures.

LANDING GEAR INSTALATION
1. Locate the two main landing gear wires, one
nose gear wire, four nylon mounting straps eight
3*12mm Phillips head sheet metal screws, three
wheels, six wheel collars w/set screws, and one
nylon steering arm with set screw.
2. There are two hardwood landing gear blocks
with one precut channel in each block in the
bottom of the wing. Locate the two landing gear
blocks on the bottom of the wing and using a
modeling knife, remove the covering from over
the precut channels.
Remove the covering 7. Locate the nose gear wire. Slide the nose gear
wire up through the lower portion of the nose
gear block, then through the nylon steering
arm, then through the upper portion of the nose
gear block. The top of the nose gear wire
should be flush with the top of the nose gear
bracket.
8. With the nose gear wire straight, angle the nylon
steering arm about 300 forward of the fire-wall
and tighten the set screw. Angling the arm
forward like this will allow room for the arm to
move back for more adequate steering.
3. Test fit the two main gear wires into the
channels. When satisfied with the fit, secure the
wires in place using the four nylon straps and
eight 3*12mm sheet metal screws. If you look
closely at the wing surface surrounding the
channel for the wire, you will notice that there
are already four pilot holes drilled to
accommodate the screws for the straps. Mount
the straps at these locations.
4. Install two of the wheels onto the axles using
the four wheel collars and set screws provided.
The wheels should be centered on the axles
with a wheel collar on each side, holding them
in place. Tighten the set screws on the collars
to secure them in place.The wheels should
rotate freely. You should apply a small drop of
lock-Tite thread lock to each set screw to
prevent them from coming loose.
5. Remove the hatch cover from the bottom front
of the fuselage. Working with the preinstalled
nylon steering housing, position it so the end of
it is flush with the front of the firewall. When
satisfied with the fit, glue the housing to the
firewall from the inside of the fuselage using 5
Minute Epoxy.
6. The preinstalled wire steering pushrod has a
factory made Z-Bend on the front end of it.
Connect the nylon steering arm to this pushrod.
The pushrod should be installed in the
outermost hole in the steering arm.

HORIZONTAL STABILIZER INSTALLATION
PARTS REQUIRED
· (1) Horizontal stabilizer with Elevator halves.
1. Using a modeling knife, cut away the covering
from the fuselage for the stabilizer and remove it.
3. Check the fit of the horizontal stabilizer in its slot.
Make sure the horizontal stabilizer is square and
centered to the fuselage by taking measurements,
but don't glue anything yet.
4. With the horizontal stabilizer correctly aligned,
mark the shape of the fuselage on the top and
bottom of the tail plane using a water soluble /
non-permanent felt-tip pen.
5. Remove the stabilizer. Using the lines you just
drew as a guide, carefully remove the covering
from between them using a modeling knife.
When cutting through the covering to remove it,
cut with only enough pressure to only cut
through the covering it's self. Cutting into the
balsa structure may weaken it. This could lead
to possible failure during flight.
2. Draw a center line onto the horizontal stabilizer.
4. Plug the aileron servo into the receiver and center
the servo. Install the servo arm onto the servo.
The servo arm should be perpendicular to the
servo and point toward the middle of the wing.

spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and
the plywood pieces to reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

!
BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

5. Place the servo into the servo tray. Center the
servo within the tray and drill 1,6mm pilot holes
through the block of wood for each of the four
mounting screws provided with the servo.
6. Using the thread as a guide and using masking
tape, tape the servo lead to the end of the
thread: carefully pull the thread out. When you
have pulled the servo lead out, remove the
masking tape and the servo lead from the
thread.
7. Place the aileron servo tray / hatch into the
servo box on the bottom of the wing and drill
1,6mm pilot holes through the tray and the
servo box for each of the four mounting screws.
Secure the servo tray in place using the

8. Repeat step # 2 - # 7 to install the second
aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

INSTALLING THE DIHEDRAL BRACE
1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.
2. Using a ruler and a pen, locate and mark the
center line of the Aluminum dihedral brace.

JOINING THE WING HALVES
1. Mix a generous amount of 30 minute epoxy.
Working with only one wing half for now, apply
a thin layer of epoxy inside the carton dihedral
brace tube and to only half of the dihedral
brace. Make sure to cover the dihedral brace
around as well as the sides, and use enough
epoxy to fill any gaps.
2. Slide the dihedral brace into the carton tube up
to the center line. Remove any excess epoxy
before it dries using a paper towel and rubbing
alcohol. Allow the epoxy to cure before
proceeding.
3. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
4. Mix a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the exposed half
of the dihedral brace, the inside of the carton
dihedral brace tube and the entire surface of
both root ribs. Make sure to use enough epoxy
to fill any gaps.
5. Slide the two wing halves together and carefully
align them at the leading and trailing edges. Wipe
away any excess epoxy using a paper towel and
rubbing alcohol. Use masking tape to hold the
two wing halves in place until the epoxy cures.
6. When the epoxy has fully cured, double check
the center section joint. If any gaps are present,
mix a small amount of 30 minute epoxy and
carefully fill any remaining gaps. Remove the
excess epoxy using a paper towel and rubbing
alcohol. Allow the epoxy to fully cure before
proceeding.

fuselage. Slide the stabilizer in place and
re-align. Double check all of your measurements
one more time before the epoxy cures. Remove
any excess epoxy using a paper towel and
rubbing alcohol and hold the stabilizer in place
with T-pins or masking tape.
2. Slide the vertical stabilizer into the slot in the
mounting platform in the top of the fuselage. Mark
the shape of the fuselage on the left and right
sides of the vertical stabilizer using a felt-tip pen.
3. Now, remove the vertical stabilizer and using
a modeling knife, carefully cut just inside the
marked lines and remove the film on both sides
of the vertical stabilizer. Just as you did with the
horizontal stabilizer, make sure you only press
hard enough to cut the film, not the balsa
vertical stabilizer.
4. Slide the vertical stabilizer back in place. Using
a triangle, check to ensure that the vertical
stabilizer is aligned 90 degree to the horizontal
stabilizer.
5. When you are sure that everything is a aligned
correctly, mix up a generous amount of 30
minute epoxy. Apply a thin layer to the slot in
the mounting platform and to the vertical
stabilizer mounting area. Apply epoxy to the
lower rudder hinge. Set the stabilizer in place
and re-align. Double check all of your
measurements once more before the epoxy
cures. Remove any excess epoxy using a

INSTALLING THE SPINNER
Install the spinner back-plate, propeller and
spinner cone. The spinner cone is held in place
using two 3mm x 20mm wood screws.
The propeller should not touch any part of the
spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and
the plywood pieces to reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.
INSTALLING THE SWITCH

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

!
BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

INSTALLING THE DIHEDRAL BRACE
1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.

forward like this will allow room for the arm to
move back for more adequate steering.
3. Test fit the two main gear wires into the
channels. When satisfied with the fit, secure the
wires in place using the four nylon straps and
eight 3*12mm sheet metal screws. If you look
closely at the wing surface surrounding the
channel for the wire, you will notice that there
are already four pilot holes drilled to
accommodate the screws for the straps. Mount
the straps at these locations.
4. Install two of the wheels onto the axles using
the four wheel collars and set screws provided.
The wheels should be centered on the axles
with a wheel collar on each side, holding them

The propeller should not touch any part of the
spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and
the plywood pieces to reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

8. Repeat step # 2 - # 7 to install the second
aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

INSTALLING THE DIHEDRAL BRACE
1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.

JOINING THE WING HALVES
1. Mix a generous amount of 30 minute epoxy.
Working with only one wing half for now, apply
a thin layer of epoxy inside the carton dihedral
brace tube and to only half of the dihedral
brace. Make sure to cover the dihedral brace
around as well as the sides, and use enough
epoxy to fill any gaps.
2. Slide the dihedral brace into the carton tube up
to the center line. Remove any excess epoxy
before it dries using a paper towel and rubbing
alcohol. Allow the epoxy to cure before
proceeding.
3. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
4. Mix a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the exposed half
of the dihedral brace, the inside of the carton
dihedral brace tube and the entire surface of
both root ribs. Make sure to use enough epoxy
to fill any gaps.

LANDING GEAR INSTALATION
1. Locate the two main landing gear wires, one
nose gear wire, four nylon mounting straps eight
3*12mm Phillips head sheet metal screws, three
wheels, six wheel collars w/set screws, and one
nylon steering arm with set screw.
2. There are two hardwood landing gear blocks
with one precut channel in each block in the
bottom of the wing. Locate the two landing gear
blocks on the bottom of the wing and using a
modeling knife, remove the covering from over
the precut channels.
Remove the covering 7. Locate the nose gear wire. Slide the nose gear
wire up through the lower portion of the nose
gear block, then through the nylon steering
arm, then through the upper portion of the nose
gear block. The top of the nose gear wire
should be flush with the top of the nose gear
bracket.
8. With the nose gear wire straight, angle the nylon
steering arm about 300 forward of the fire-wall
and tighten the set screw. Angling the arm
forward like this will allow room for the arm to
move back for more adequate steering.
3. Test fit the two main gear wires into the
channels. When satisfied with the fit, secure the
wires in place using the four nylon straps and
eight 3*12mm sheet metal screws. If you look
closely at the wing surface surrounding the
channel for the wire, you will notice that there
are already four pilot holes drilled to
accommodate the screws for the straps. Mount
the straps at these locations.
4. Install two of the wheels onto the axles using
the four wheel collars and set screws provided.
The wheels should be centered on the axles
with a wheel collar on each side, holding them
in place. Tighten the set screws on the collars
to secure them in place.The wheels should
rotate freely. You should apply a small drop of
lock-Tite thread lock to each set screw to
prevent them from coming loose.
5. Remove the hatch cover from the bottom front
of the fuselage. Working with the preinstalled
nylon steering housing, position it so the end of
it is flush with the front of the firewall. When
satisfied with the fit, glue the housing to the
firewall from the inside of the fuselage using 5
Minute Epoxy.
6. The preinstalled wire steering pushrod has a
factory made Z-Bend on the front end of it.
Connect the nylon steering arm to this pushrod.
The pushrod should be installed in the
outermost hole in the steering arm.

HORIZONTAL STABILIZER INSTALLATION
PARTS REQUIRED
· (1) Horizontal stabilizer with Elevator halves.
1. Using a modeling knife, cut away the covering
from the fuselage for the stabilizer and remove it.
3. Check the fit of the horizontal stabilizer in its slot.
Make sure the horizontal stabilizer is square and
centered to the fuselage by taking measurements,
but don't glue anything yet.
4. With the horizontal stabilizer correctly aligned,
mark the shape of the fuselage on the top and
bottom of the tail plane using a water soluble /
non-permanent felt-tip pen.
5. Remove the stabilizer. Using the lines you just
drew as a guide, carefully remove the covering
from between them using a modeling knife.
When cutting through the covering to remove it,
cut with only enough pressure to only cut
through the covering it's self. Cutting into the
balsa structure may weaken it. This could lead
to possible failure during flight.
2. Draw a center line onto the horizontal stabilizer.
4. Plug the aileron servo into the receiver and center
the servo. Install the servo arm onto the servo.
The servo arm should be perpendicular to the
servo and point toward the middle of the wing.

spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

!
BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

5. Place the servo into the servo tray. Center the
servo within the tray and drill 1,6mm pilot holes
through the block of wood for each of the four
mounting screws provided with the servo.
6. Using the thread as a guide and using masking
tape, tape the servo lead to the end of the
thread: carefully pull the thread out. When you
have pulled the servo lead out, remove the
masking tape and the servo lead from the
thread.
7. Place the aileron servo tray / hatch into the
servo box on the bottom of the wing and drill
1,6mm pilot holes through the tray and the
servo box for each of the four mounting screws.
Secure the servo tray in place using the
mounting screws provided ( 2mm x 12mm ).
8. Repeat step # 2 - # 7 to install the second
aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

INSTALLING THE DIHEDRAL BRACE
1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.
2. Using a ruler and a pen, locate and mark the
center line of the Aluminum dihedral brace.

JOINING THE WING HALVES
1. Mix a generous amount of 30 minute epoxy.
Working with only one wing half for now, apply
a thin layer of epoxy inside the carton dihedral
brace tube and to only half of the dihedral
brace. Make sure to cover the dihedral brace
around as well as the sides, and use enough
epoxy to fill any gaps.
2. Slide the dihedral brace into the carton tube up
to the center line. Remove any excess epoxy
before it dries using a paper towel and rubbing
alcohol. Allow the epoxy to cure before
proceeding.
3. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
4. Mix a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the exposed half
of the dihedral brace, the inside of the carton
dihedral brace tube and the entire surface of
both root ribs. Make sure to use enough epoxy
to fill any gaps.
5. Slide the two wing halves together and carefully
align them at the leading and trailing edges. Wipe
away any excess epoxy using a paper towel and
rubbing alcohol. Use masking tape to hold the
two wing halves in place until the epoxy cures.
6. When the epoxy has fully cured, double check
the center section joint. If any gaps are present,
mix a small amount of 30 minute epoxy and
carefully fill any remaining gaps. Remove the
excess epoxy using a paper towel and rubbing
alcohol. Allow the epoxy to fully cure before
proceeding.

correctly, mix up a generous amount of 30
minute epoxy. Apply a thin layer to the top and
bottom of the stabilizer mounting area and to the
stabilizer mounting platform sides in the
fuselage. Slide the stabilizer in place and
re-align. Double check all of your measurements
one more time before the epoxy cures. Remove
any excess epoxy using a paper towel and
rubbing alcohol and hold the stabilizer in place
with T-pins or masking tape.
2. Slide the vertical stabilizer into the slot in the
mounting platform in the top of the fuselage. Mark
the shape of the fuselage on the left and right
sides of the vertical stabilizer using a felt-tip pen.
3. Now, remove the vertical stabilizer and using
a modeling knife, carefully cut just inside the
marked lines and remove the film on both sides
of the vertical stabilizer. Just as you did with the
horizontal stabilizer, make sure you only press
hard enough to cut the film, not the balsa
vertical stabilizer.
4. Slide the vertical stabilizer back in place. Using
a triangle, check to ensure that the vertical
stabilizer is aligned 90 degree to the horizontal
stabilizer.
5. When you are sure that everything is a aligned
correctly, mix up a generous amount of 30
minute epoxy. Apply a thin layer to the slot in
the mounting platform and to the vertical
stabilizer mounting area. Apply epoxy to the
lower rudder hinge. Set the stabilizer in place
and re-align. Double check all of your
measurements once more before the epoxy
cures. Remove any excess epoxy using a
paper towel and rubbing alcohol and hold the
stabilizer in place with T-pins or masking tape.

INSTALLING THE SPINNER
Install the spinner back-plate, propeller and
spinner cone. The spinner cone is held in place
using two 3mm x 20mm wood screws.
The propeller should not touch any part of the
spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and
the plywood pieces to reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.
INSTALLING THE SWITCH

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

!
BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

INSTALLING THE DIHEDRAL BRACE
1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.

brace tube and to only half of the dihedral
brace. Make sure to cover the dihedral brace
around as well as the sides, and use enough
epoxy to fill any gaps.
2. Slide the dihedral brace into the carton tube up
to the center line. Remove any excess epoxy
before it dries using a paper towel and rubbing
alcohol. Allow the epoxy to cure before
proceeding.
3. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
4. Mix a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the exposed half
of the dihedral brace, the inside of the carton
dihedral brace tube and the entire surface of
both root ribs. Make sure to use enough epoxy

forward like this will allow room for the arm to
move back for more adequate steering.
3. Test fit the two main gear wires into the
channels. When satisfied with the fit, secure the
wires in place using the four nylon straps and
eight 3*12mm sheet metal screws. If you look
closely at the wing surface surrounding the
channel for the wire, you will notice that there
are already four pilot holes drilled to
accommodate the screws for the straps. Mount
the straps at these locations.
4. Install two of the wheels onto the axles using
the four wheel collars and set screws provided.
The wheels should be centered on the axles
with a wheel collar on each side, holding them

INSTALLING THE SPINNER
Install the spinner back-plate, propeller and
spinner cone. The spinner cone is held in place
using two 3mm x 20mm wood screws.
The propeller should not touch any part of the
spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Position the battery pack and receiver behind
the fuel tank. Use the two light plywood pieces,
placed over the battery and receiver and glue
to the fuselage sides to hold the battery and
receiver securely in place. Use 15mm triangle
pieces glued between the fuselage sides and
the plywood pieces to reinforce the joints.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.
INSTALLING THE SWITCH

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the
wing onto the fuselage.
We wish you many enjoyable flights with
your plane and once again thank you for
your choosing a Phoenix Model's product.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.

BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 10mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUELTANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 150mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of
lead weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose
down when you lift it up with your fingers.
Ailerons : 8mm up 8mm down
Elevator : 12mm up 12mm down
Rudder : 15mm right 15mm left
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help the
airplane track straighter.
1. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require two
people to make it easier.
2. If one side of the wing fall, that side is heavier than
the opposite. Add small amounts of lead weight to
the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level
when you lift the airplane.

8. Repeat step # 2 - # 7 to install the second
aileron servo in the opposite wing half.
9. Using masking tape, tape the servo leads on to
the top of the wing.
3. Test fit the dihedral brace into the carton tube in
each wing half. The brace should slide into
each wing half up to the center line. If it does
not, remove the brace and lightly sand the
edges and tips until the proper fit is obtained.
4. Test fit both of the wing halves together with the
dihedral brace temporarily installed. Do not
glue it in at this time! The wing halves should fit
together tight with little or no gaps in the center
section joint. If the center section joint is not
tight, remove the wing halves and lightly sand
the edges and tips of the dihedral brace. Test fit
the wing halves together with the dihedral
brace installed again. Repeat until you are
satisfied with the fit of the wing halves. The
proper dihedral is built into the two root ribs and
should not be altered.
5. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

INSTALLING THE DIHEDRAL BRACE
1. Look carefully at the surface of each root rib on
both wing halves. Notice how the excess
covering material overlaps onto them. Using a
modeling knife, carefully cut out away the
covering from both root ribs. Iron the covering
down so that it does not pull away from the ribs.
It is important that the excess covering be
removed from the root ribs. This will ensure an
adequate wood to wood glue joint.
2. Using a ruler and a pen, locate and mark the
center line of the Aluminum dihedral brace.

JOINING THE WING HALVES
1. Mix a generous amount of 30 minute epoxy.
Working with only one wing half for now, apply
a thin layer of epoxy inside the carton dihedral
brace tube and to only half of the dihedral
brace. Make sure to cover the dihedral brace
around as well as the sides, and use enough
epoxy to fill any gaps.
2. Slide the dihedral brace into the carton tube up
to the center line. Remove any excess epoxy
before it dries using a paper towel and rubbing
alcohol. Allow the epoxy to cure before
proceeding.
3. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
4. Mix a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the exposed half
of the dihedral brace, the inside of the carton
dihedral brace tube and the entire surface of
both root ribs. Make sure to use enough epoxy
to fill any gaps.
5. Slide the two wing halves together and carefully
align them at the leading and trailing edges. Wipe
away any excess epoxy using a paper towel and
rubbing alcohol. Use masking tape to hold the
two wing halves in place until the epoxy cures.

LANDING GEAR INSTALATION
1. Locate the two main landing gear wires, one
nose gear wire, four nylon mounting straps eight
3*12mm Phillips head sheet metal screws, three
wheels, six wheel collars w/set screws, and one
nylon steering arm with set screw.
2. There are two hardwood landing gear blocks
with one precut channel in each block in the
bottom of the wing. Locate the two landing gear
blocks on the bottom of the wing and using a
modeling knife, remove the covering from over
the precut channels.
Remove the covering 7. Locate the nose gear wire. Slide the nose gear
wire up through the lower portion of the nose
gear block, then through the nylon steering
arm, then through the upper portion of the nose
gear block. The top of the nose gear wire
should be flush with the top of the nose gear
bracket.
8. With the nose gear wire straight, angle the nylon
steering arm about 300 forward of the fire-wall
and tighten the set screw. Angling the arm
forward like this will allow room for the arm to
move back for more adequate steering.
3. Test fit the two main gear wires into the
channels. When satisfied with the fit, secure the
wires in place using the four nylon straps and
eight 3*12mm sheet metal screws. If you look
closely at the wing surface surrounding the
channel for the wire, you will notice that there
are already four pilot holes drilled to
accommodate the screws for the straps. Mount
the straps at these locations.
4. Install two of the wheels onto the axles using
the four wheel collars and set screws provided.
The wheels should be centered on the axles
with a wheel collar on each side, holding them
in place. Tighten the set screws on the collars
to secure them in place.The wheels should
rotate freely. You should apply a small drop of
lock-Tite thread lock to each set screw to
prevent them from coming loose.
5. Remove the hatch cover from the bottom front
of the fuselage. Working with the preinstalled
nylon steering housing, position it so the end of
it is flush with the front of the firewall. When
satisfied with the fit, glue the housing to the
firewall from the inside of the fuselage using 5
Minute Epoxy.
6. The preinstalled wire steering pushrod has a
factory made Z-Bend on the front end of it.
Connect the nylon steering arm to this pushrod.
The pushrod should be installed in the
outermost hole in the steering arm.

installing the engine
Locate the long piece of wire used for the throttle
pushrod. One end of the wire has been pre-bend in
to a "Z" bend at the factory. This "Z" bend should be
inserted into the throttle arm of the engine when the
engine is fitted onto the engine mount. Fit the engine
to the engine mount using the screws provided.
FUEL TANK
PARTS REQUIRED
· (1) Nylon fuel tank.
· (1) Metal clunk.
· (1) Silicon tube.
· (1) Pre-assemble stopper.
· (1) 165mm x 250mm foam.
INSTALLING THE STOPPER ASSEMBLY
1. The stopper has been pre-assembled at the factory.
2. Using a modeling knife, cut one length of silicon
fuel line (the length of silicon fuel line is
calculated by how the weighted clunk should rest
about 8mm away from the rear of the tank and
move freely inside the tank). Connect one end of
the line to the weighted clunk and the other end
to the nylon pick up tube in the stopper.
3. Carefully bend the second nylon tube up at a
45 degree angle (using a cigarette lighter). This
tube will be the vent tube to the muffler.
4. Carefully bend the third nylon tube down at a
45 degree angle (using a cigarette lighter). This
tube will be vent tube to the fueling valve
When the stopper assembly is installed in the
tank, the top of the vent tube should rest just
below the top surface of the tank. It should not
touch the top of the tank.

9. Install the remaining wheel onto the axle using
the two wheel collars and set screws provided.
The wheel should be centered on the axle with
a wheel collar on each side, holding it in place.
Tighten the set screws on the collars to secure
them in place. The wheel should rotate freely.
You should apply a small drop of Lock_tite
thread lock to each set screw to prevent them
from coming loose.
ENGINE INSTALLATION
PARTS REQUIRED
• (4) 3mm x 25mm wood csrews
• (1) 1.3mm x 500mm wire.
• (1) 3.5mm x 350 mm nylon pushrod housing.
• (1) Metal connector.
INSTALLING THE THROTTLE
PUSHROD HOUSING
1. Place the engine into the engine mount and
align it properly with the front of the cowling.
The distance from the firewall to the front of
the engine thrust washer should [100mm]
If your engine is equipped with a remote needle
valve, we suggest installing it into the engine
at this time.
2. When satisfied with the alignment of the engine,
use a pencil and mark the mounting hole
location onto the firewall, where the throttle
pushrod will exit.
3. Now, remove the engine. Using a 5mm drill bit,
drill holes through the firewall and the forward
bulkhead at the marks made.
4. Slide the pushrod housing through the hole in
the firewall, through the hole in the forward
bulkhead, and into the servo compartment.
5. Apply a couple of drops of thin C/Ato the
pushrod housing where it exits the firewall and
where it passes through the forward bulkhead.
This will secure the housing in place.
6. Using a modeling knife, cut off the nylon pushrod
housing 26mm in front of the servo tray.

8. Insert the 90 degree bend down through the hole
in the servo arm. Install one nylon snap keeper
over the wire to secure it to the arm. Install the
servo arm retaining screw and remove the
masking tape from the aileron.
9. Repeat step # 4 - # 11 to install the second aileron
linkage.
HORIZONTAL STABILIZER INSTALLATION
PARTS REQUIRED
· (1) Horizontal stabilizer with Elevator halves.
1. Using a modeling knife, cut away the covering
from the fuselage for the stabilizer and remove it.
3. Check the fit of the horizontal stabilizer in its slot.
Make sure the horizontal stabilizer is square and
centered to the fuselage by taking measurements,
but don't glue anything yet.
4. With the horizontal stabilizer correctly aligned,
mark the shape of the fuselage on the top and
bottom of the tail plane using a water soluble /
non-permanent felt-tip pen.
5. Remove the stabilizer. Using the lines you just
drew as a guide, carefully remove the covering
from between them using a modeling knife.
When cutting through the covering to remove it,
cut with only enough pressure to only cut
through the covering it's self. Cutting into the
balsa structure may weaken it. This could lead
to possible failure during flight.
2. Draw a center line onto the horizontal stabilizer.
4. Plug the aileron servo into the receiver and center
the servo. Install the servo arm onto the servo.
The servo arm should be perpendicular to the
servo and point toward the middle of the wing.
5. Center the aileron and hold it in place using a
couple of pieces of masking tape.
6. With the aileron and aileron servo centered,
carefully place a mark on the aileron pushrod
wire where it crosses the hole in the servo arm.
7. Using pliers, carefully make a 90 degree bend
down at the mark made. Cut off the excess
wire, leaving about 4mm beyond the bend.

ALMOST READY TO FLY
I/C FLIGHT GUIDELINES
Made in Vietnam
When ready to fly, first extend the
transmitter aerial.
Operate the control sticks on the
transmitter and check that the control
surfaces move freely and in the
CORRECT directions. ALWAYS land the model INTO the
wind, this ensures that the model lands
at the slowest possible speed.
Switch on the transmitter.
Switch off the transmitter.
Check that the transmitter batteries
have adequate power.
Switch off the receiver.
Switch on the receiver. ALWAYS take off into the wind.
Check that the wings are correctly
fitted to the fuselage. If the model does not respond correctly
to the controls, land it as soon as
possible and correct the fault.
Empty the fuel tank after flying, fuel left
in the tank can cause corrosion and
lead to engine problems.
