SUGGESTION
To avoid scratching your new airplane, do not
unwrap the pieces until they are needed for
assembly. Cover your workbench with an old towel
or brown paper, both to protect the aircraft and to
protect the table. Keep a couple of jars or bowls
handy to hold the small parts after you open the
bag.
NOTE:
Please trial fit all the parts. Make sure you have
the correct parts and that they fit and are aligned
properly before gluing! This will assure proper
assembly. The STREGA ARF is hand made from
natural materials, every plane is unique and minor
adjustments may have to be made. However, you
should find the fit superior and assembly simple.
The painted and plastic parts used in this kit are
fuel proof. However, they are not tolerant of many
harsh chemicals including the following: paint
thinner, C/A glue accelerator, C/A glue debonder
and acetone. Do not let these chemicals come in
contact with the colors on the covering and the
plastic parts.
SAFETY PRECAUTION:
• This is not a toy
• Be sure no other flyers are using your radio
frequency.
• Do not smoke near fuel
• Store fuel in a cool, dry place, away from
children and pets.
• Wear safety glasses.
• The glow plug clip must be securely attached to
the glow plug.
• Do not flip the propeller with your fingers.
• Keep loose wires and clothing away from the
propeller.
• Do not start the engine if people are near. Do not
stand in line with the side of the propeller.
• Make engine adjustments from behind the
propeller only. Do not reach around the spinning
propeller.

INSTALLING THE AILERON SERVOS
1. Install the rubber grommets and brass eyelets
onto the aileron servo.
2. Turn the wing panel right side up. Using a
modeling knife, remove the covering from over
the precut servo lead exit hole in the root rib and
the top of the wing sheeting. This hole will allow
the servo leads to pass through when the wing
halves are joined.
3. Using a modeling knife, remove the covering from
over the pre-cut servo arm exit hole on the servo
tray/hatch. This hole will allow the servo arm to
pass through when installing the aileron pushrod.
4. Using medium C.A Glue, glue two blocks of
wood onto the servo tray. Use your servo to
space the blocks properly. Position the blocks
so that the servo arm exits the center of the slot
in the servo tray.

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 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 the opposite wing half.
9. Using masking tape, tape the servo lead on to
the top of the wing.
INSTALLING THE DIHEDRAL BRACE
10. 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 and will help
prevent wing failure during flight.
11. Using a ruler and a pen, locate and mark the
center line of the hardwood dihedral brace.
Draw the vertical line at this location on each of
the brace.
12. Test fit the dihedral brace into the plywood box
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.
13. 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.
14. When satisfied with the fit of the wing halves,
remove the wing halves and the dihedral brace.

bit, enlarge the third hole out from the center of the
arm to accommodate the aileron pushrod wire.
7. Plug the aileron servo into the receiver, turn on
the radio system and center the servo. Install
the servo arm into the servo. The servo arm
should be perpendicular to the servo and point
toward the middle of the wing.
8. Center the aileron and hold it in place using a
couple of pieces of masking tape.
9. 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.
10. Using pliers, carefully make a 90 degree bend
down at the mark made. Cut off the excess
wire, leaving about 4mm beyond the bend.
11. 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.
12. Repeat step # 4 - # 11 to install the second
aileron linkage. After both linkages are
completed, connect both of the aileron servo
leads using the Y - harness you purchased
separately.
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 horizontal 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 horizontal stabilizer 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'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.

6. When you are sure that everything is aligned
correctly, mix up a generous a mount 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, making 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 and 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. Allow the
epoxy to fully cure before proceeding.
7. After the epoxy has fully cured, remove the
masking tape or T-pins used to hold the
stabilizer in place and carefully inspect the glue
joints. Use more epoxy to fill in any gaps that
were not filled previously and clean up the
excess using a paper towel and rubbing
alcohol.

touch the top of the tank.
!!!
5. Test fit the stopper assembly into the tank. It
may be necessary to trim some of the flashing
around the tank opening using a modeling knife.
If flashing is present, make pure none falls into
the tank.
6. When satisfied with the alignment of the stopper
assembly tighten the 3mm x 20mm machine
screw until the rubber stopper expand and seals
the tank opening. Do not over tighten the
assembly at this could cause the tank to split.
7. Using a modeling knife, cut 3 lengths of fuel line
150mm long. Connect 2 lines to the 2 vent tubes
and 1 line to the fuel pickup tube in the stopper.
8. Feed three lines through the fuel tank
compartment and through the pre-drilled hole in
the firewall. Pull the lines out from behind the
engine, while guiding the fuel tank into place.
Push the fuel tank as far forward as possible, the
front of the tank should just about touch the back
of the firewall.
Blow through one of the lines to ensure the fuel
lines have not become kinked inside the fuel
tank compartment. Air should flow through easily.
9. To secure the fuel tank in place, apply a bead of
silicone sealer to the forward area of the tank,
where it exits the fuselage behind the engine
mounting box and to the rear of the tank at the
forward bulkhead.

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
5. The switch should be mounted on the fuselage
side, opposite the muffler, close enough to the
receiver so the lead will reach. Use the face
plate of the switch cut out the opening and
locate mounting holes.
6. Cut out the switch hole using a modeling knife.
Use a 2mm drill bit and drill out the two
mounting holes through the fuselage side.
7. Secure the switch in place using the two
machine screws provided with the radio system.

INSTALLING THE WING FILLET
1. When satisfied with the fit, hold the wing fillet in
place on the fuselage using pieces of masking
tape.
2. With the wing fillet hold firmly in place and
aligned properly, use a felt tip pen and outline
the wing fillet onto the fuselage surface.
3. Remove the wing fillet. Using the lines as a
guide, use a modeling knife and carefully
remove the covering from just inside the edge
of each line. Be careful not to cut in to the balsa
under the covering.
4. Mix up a generous amount of 30 minute epoxy.
Apply a thin layer of epoxy to the bottom of the
wing fillet. Carefully set the wing fillet back in
place on the fuselage and align it as you did
previously. Remove any excess epoxy using a
paper towel and rubbing alcohol.
5. Hold the wing fillet firmly in place using strips of
masking tape along the entire gluing surface.
Allow the epoxy to fully cure before you remove
the masking tape.

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 125mm
BACK FROM THE LEADING EDGE OF THE
WING, AT THE FUSELAGE. This location is
recommended for initial test flying and trimming.
There is a 5mm margin forward and aft. BALANCE
A PLANE UPSIDE DOWN WITH THE FUEL TANK
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 125mm bach 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
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.

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 falls, 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.
CONTROL THROWS
1. We highly recommend setting up a plane using the
control throws listed.
2. The control throws should be measured at the
widest point of each surface!.
3. Check to be sure the control surfaces move in the
correct directions.

JOINING THE WING HALVES
15. Mix a generous amount of 30 minute epoxy.
Working with only one wing half for now, apply
a thin layer of epoxy inside the plywood
dihedral brace box and to only half of the
dihedral brace. Make sure to cover the dihedral
brace top and bottom as well as the sides, and
use enough epoxy to fill any gaps.
16. Slide the dihedral brace into the plywood box
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.
17. Once the epoxy has cured, trial fit both wing
halves together to double check that the wing
halves still fit correctly.
18. 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 plywood
dihedral brace box and the entire surface of
both root ribs. Make sure to use enough epoxy
to fill any gaps.
19. 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.
20. 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.
21. Apply the trim tape to the center section of the
wings where they join.

leading edge, in line with the aileron pushrod.
2. Drill two 2mm holes through the aileron using
the control horn as a guide and screw the
control horn in place.
Apply a couple of drops of thin C/A to the nut to
prevent it from loosening. Allow the glue to cure
completely before proceeding. If the screws are
too long, cut them shorter if necessary.
3. Repeat step # 1 - # 2 to install the control horn
