Required Parts
• Right and left wing panels w/ailerons
• CA hinges (6)
Required Tools and Adhesives
• Thin CA • CA remover/debonder
• Paper towel • T-pins
• Drill bit: 1/16" • Drill
  Step 1
Carefully remove the tape holding the aileron and flap
to the wing. Use a 1/16" drill bit to drill into the wing
and aileron. This allows the CA to wick farther into the
surfaces for better hinge installation.
  Step 2
Locate three CA hinges and place a T-pin in the center of
the hinge as shown. Slide each of the three hinges into
the aileron so the T-pin is resting against the leading edge
of the aileron. The slot in the hinge aligns with the hole
drilled in Step 1.
  Step 3
Slide the aileron onto the wing until there is only a slight
gap between the aileron and wing panel. Remove the
T-pins and snug the aileron against the wing panel. Slide
the aileron towards the wing tip until there is only a 1/32"
gap between the end of the aileron and wing tip.
Note: Do not use CA accelerator during the
hinging process. The CA must be allowed to
soak into the hinge to provide the best bond.
Using accelerator will not provide enough time
for this process.
  Step 4
Deflect the aileron and apply thin CA to the hinge.
Apply enough CA to completely saturate the hinge.
Use care not to deflect the aileron so it pulls away from
the wing. When the hinge is glued in place, there
should be no more than a 1/64" hinge gap maintained
throughout the length of the aileron.
Section 1 – Aileron Installation

7
  Step 5
Turn the wing panel over, deflect the aileron in the
opposite direction and apply thin CA to the other side of
the hinges as described in the previous step. Make sure
the thin CA penetrates completely into both the aileron
and wing panel.
  Step 6
Use CA remover/debonder and a paper towel to remove
any excess CA accumulated on the wing or aileron
surface. Allow time for the CA to completely cure before
moving to the next step.
  Step 7
Firmly grasp the wing and aileron and gently pull on the
aileron to ensure the hinges are secure and cannot be
pulled apart. Use caution when gripping the wing and
aileron to avoid crushing the structure.
  Step 8
Work the aileron up and down several times to work in the
hinges and check for proper movement.
 Step 9
Repeat Steps 1 through 8 for the remaining aileron.

Required Tools and Adhesives
• Phillips screwdriver • Felt-tipped pen
• String/dental floss • Ruler
• Drill bit: 1/16", 1/8" • Drill
• 6-minute epoxy • Thin CA
  Step 1
Locate the aileron hatch. Note the position of the slot in
the hatch, as the left and right hatches are different.
Note: The aileron servo is mounted directly
to the hatch.
  Step 2
Install the recommended servo hardware (grommets and
eyelets) supplied with the servo. Install a long half servo
arm (JRPA212) onto the servo.
  Step 3
Locate the servo mounting blocks. Use 6-minute epoxy to
glue them in place on the marks made on the hatch. The
blocks are positioned so the tallest edge is upright. Let the
epoxy fully cure before proceeding to the next step.
  Step 4
Place the aileron servo between the mounting blocks and
use a felt-tipped pen to mark the location of the four servo
mounting screws. Note that the servo must not touch the
hatch in order to isolate engine vibration.
Section 2 – Aileron Servo Installation

9
Note: Before mounting the servo, it is
suggested to electronically center the servo
using the transmitter, then install the servo arm
to avoid having to remove the servo and center
the arm later. It may be necessary to slightly
trim one of the servo mounting blocks to clear
the servo wire.
  Step 5
Remove the servo and use a 1/16" drill bit to pre-drill
the holes for the servo mounting screws marked in the
previous step. Use the screws supplied with the servo
to mount it to the servo mounting blocks. Remove the
portion of the arm not extending out of the hatch.
  Step 6
Connect a 24" Servo Lead extension (JRPA212) to the
servo lead. Secure the connectors by tying them in a knot
using dental floss (as shown) or by using a commercially
available connector clamp to prevent the servo leads from
becoming disconnected.
Note: It is always a good idea to secure the
servo connector and servo extension together
to prevent the wires from becoming unplugged
inside the wing.
  Step 7
Slide the servo lead through the tube in the wing. The lead
will exit in the opening for the flap servo.
  Step 8
Place the hatch in position on the wing. Secure the hatch
using six #2 x 1/2" screws.
Section 2 – Aileron Servo Installation

10
  Step 9
Thread a clevis onto the end of the threaded rod. The
threaded rod should just be visible between the forks
of the clevis.
  Step 10
Remove the back plate from the control horn using side
cutters or a sharp hobby knife. Use a 1/8" drill bit to drill
out the mounting holes in the control horn.
  Step 11
Attach the clevis to the control horn. Position the control
on the aileron by aligning the linkage with the servo arm
slot and aligning the holes of the control horn with the
hinge line of the aileron. Use a felt-tipped pen to mark the
locations for the horn screws.
Hint: Wrap a piece of tape around your drill
bit to drill the holes the correct depth.
  Step 12
Drill three 1/16" holes at the locations marked in the
previous step. The holes only need to be 7/16" deep; don’t
drill through the top of the aileron.
Section 2 – Aileron Servo Installation

11
  Step 13
Install one of the #2 x 1/2" screws into a hole drilled,
then remove it. Place 2–3 drops of thin CA into the hole
to harden the wood. This will eliminate the potential of the
screw pulling out of the wood. Repeat this for each of the
three holes.
  Step 14
Attach the control horn using three #2 x 1/2" screws.
  Step 15
Mark the pushrod where it crosses the servo arm. Bend
the wire 90-degrees with the smallest radius as possible
without damaging the wire. Slide the wire through the
servo arm and snap the keeper onto the wire to complete
the procedure.
Note: The servo arm will need to be drilled
out using a 7/64" drill bit to accept the
control rod.
 Step 16
Repeat Steps 1 through 15 for the remaining aileron
servo linkage.
Section 2 – Aileron Servo Installation

12
Required Parts
• Wing assembly • Nylon flap hinges (6)
Required Tools and Adhesives
• 30-minute epoxy • Paper towels
• Rubbing alcohol • Petroleum jelly
Note: Using two standard rotation servos and
a standard Y-harness for the flaps will result
in them moving in opposite directions instead
of the same direction. As such, the flap servo
installation will either require the use of a
one reversed rotation servo and one standard
rotation servo or a reversing Y-harness. It is
highly recommended to use a computer radio
or a JR® MatchBox™ to link the two flap
servos to operate properly.
  Step 1
Locate three of the nylon flap hinges. Apply a small
amount of petroleum jelly to the hinge joint to prevent the
epoxy from preventing movement of the hinge.
  Step 2
Locate the holes in the wing and flap for the flap hinges.
Remove the covering if necessary from each hole. There
will be a total of three holes each in the wing and flap.
  Step 3
Install the hinges in the flap and slide the flap into
position. Check to make sure the flap aligns with both the
aileron and wing trailing edge. If it does not, move the
hinges in or out until the flap is in alignment.
Section 3 – Flap Installation

13
  Step 4
Use 30-minute epoxy to install the hinges. Apply epoxy
to both the holes in the flap and wing using a toothpick.
Apply a light coat of epoxy to the hinge. Slide the flap
into position, and move it up and down to make sure the
hinges are aligned. Use tape around the division between
the flap and wing, as well as the flap and aileron, to hold
the flap until the epoxy fully cures.
Note: Pacer hinge glue can be used instead of
epoxy for gluing the flap hinges.
 Step 5
Repeat Steps 1 through 4 for the remaining flap.

  Step 2
Locate the servo mounting blocks. Use 6-minute epoxy to
glue them in place on the marks on the flap servo hatch.
Let the epoxy fully cure before proceeding to the next step.
  Step 3
Place the flap servo between the mounting blocks so the
output spline will be towards the leading edge of the wing.
Center the servo using the radio. Install the servo arm so
it is angled forward around 30 degrees. Use a felt-tipped
pen to mark the location of the four mounting screws.
Note: The servo must not touch the hatch in
order to isolate it from engine vibration.
  Step 4
Remove the servo and use a 1/16" drill bit to predrill
the holes for the servo mounting screws marked in the
previous step. Use the screws supplied with the servo to
mount it to the servo mounting blocks.
  Step 5
Connect a 6" Servo Lead extension (JRPA094) to the
servo lead. Secure the connectors by tying them in a knot
using dental floss (as shown) or by using a commercially
available connector clamp to prevent the servo leads from
becoming disconnected.
Note: It is always a good idea to secure the
servo connector and servo extension together
to prevent the wires from becoming unplugged
inside the wing.
Section 4 – Flap Servo Installation

15
  Step 6
Prepare the flap linkage by threading a 4-40 clevis onto
the pushrod. Bend the rod at a 90-degree angle 3 3/8" from
the end of the rod as shown.
  Step 7
Attach the clevis to the flap control horn.
  Step 8
Attach the flap linkage to the servo arm using
the wire keeper.
Note: The servo arm will need to be drilled
out using a 7/64" drill bit to accept the
control rod.
  Step 9
Tape the aileron servo lead down so it won’t interfere with
the flap servo operation. Pass the servo lead for the flap
and aileron servos outside the wing. Place the hatch into
position, and connect the servo to the receiver. With the
radio on, adjust the linkage so the flap is in neutral. Once
adjusted, secure the hatch using six #2 x 1/2" screws.
 Step 10
Repeat Steps 1 through 9 for the remaining flap
servo linkage.

to use low profile retract servos, such as the
JRPS791. All adjustments to the retracts are
made before the final installation.
  Step 1
Position the retract mechanism over the wing to determine
on which side to mount the retract servo. Use a 4-40 tap
to tap the appropriate holes in the mounting plate.
  Step 2
Mount the retract servo to the mounting plate using four
4-40 socket head screws. It may be necessary to install
the spacer plates depending on the servo selected.
  Step 3
Attach the servo horn to the retract servo. It is
positioned so the arm moves from one end of the
mechanism to the other.
  Step 4
Assemble and install the linkage. Attach the clevis to the
retract actuator, and use a 4-40 screw to attach the ball-
link to the servo arm.
Section 5 – Retract Installation

17
  Step 5
Check that the retract fully locks at both up and down
positions without stalling the servo. Adjust the length of
the linkage and the position of the linkage at the servo
until both up and down locked positions are achieved.
  Step 6
Once the retracts are fully adjusted, install them
into the wing and secure their position using four
6-32 x 1/2" screws.

Required Parts
• Stabilizer • CA hinges (6)
• Elevator (right and left)
Required Tools and Adhesives
• T-pins • Thin CA
• Paper towels • CA remover/debonder
• Drill bit: 1/16" • Drill
  Step 1
Locate four CA hinges and place a T-pin in the center
of the hinge as shown. Drill 1/16" holes at each hinge
location on the elevator and stabilizer. Slide each of the
three hinges into the elevator so the T-pin is resting
against the leading edge of the elevator.
  Step 2
Slide the elevator onto the stabilizer until there is
only a slight gap between the stabilizer and elevator.
Remove the T-pins and snug the elevator against the
stabilizer. Position the elevator so the tip aligns with
the tip of the stabilizer.
Note: Do not use CA accelerator during the
hinging process. The CA must be allowed to
soak into the hinge to provide the best bond.
Using accelerator will not provide enough time
for this process.
  Step 3
Deflect the elevator and apply thin CA to the hinge. Apply
enough CA to completely saturate both the top and bottom
of the hinge. Use care not to deflect the elevator so it
pulls away from the stabilizer. When the hinge is glued in
place, there should be no more than a 1/32" hinge gap
maintained throughout the length of the elevator.
  Step 4
Use CA remover/debonder and a paper towel to remove
any excess CA accumulated on the stabilizer or elevator
surface. Allow time for the CA to completely cure before
moving to the next step.
  Step 5
Firmly grasp the elevator and stabilizer and gently pull
them apart to ensure the hinges are secure and cannot be
pulled apart. Use caution when gripping them to avoid
crushing the structure.
  Step 6
Work the elevator up and down several times to work in
the hinges and check for proper movement.
 Step 7
Repeat Steps 1 through 6 for the remaining elevator.

Required Parts
• Fuselage assembly • Rudder
• CA hinges (3)
Required Tools and Adhesives
• T-pins • Thin CA
• Paper towels • CA remover/debonder
• Drill bit: 1/16" • Drill
Note: Hinging the rudder follows the same
procedure as hinging the ailerons and
elevators, condensed below into just a few
steps.
 Step 1
Locate three CA hinges and place a T-pin in the center
of each hinge. Use a 1/16" drill bit to drill holes into the
rudder and fin for each hinge location. Slide the hinges
into the rudder.
 Step 2
Slide the rudder onto the fin. Align the top of the rudder
with the top of the fin. Remove the T-pins and use
thin CA to glue the hinges into position. Apply CA to
both sides of the hinges.
Note: Do not use CA accelerator during the
hinging process. The CA must be allowed to
soak into the hinge to provide the best bond.
Using accelerator will not provide enough time
for this process.
 Step 3
Clean up any excess CA using CA remover/debonder.
Once the CA has fully cured, gently pull on the rudder to
ensure the hinges are secure. Flex the rudder a few times
to work in the hinges.

Required Parts
• Wing panels • Fuselage
• Wing tube • Stabilizer tube
• Tap handle • 4-40 tap
• Drill • Drill bit: #43
• 1/4-20 x 2" nylon bolt (2)
• 4-40 x 1/2" socket head screw (2)
Required Tools and Adhesives
• Flat screwdriver w/short handle
 Step 1
Remove the four 4-40 x1/2” screws securing the hatch
to the fuselage. Remove the hatch and store it in a safe
place until later.
 Step 2
Locate the wing tube and carefully slide it into one
wing panel. Slide the wing (with tube) into the wing
tube opening in the fuselage. Make sure the wing panel
alignment pins slide into the holes provided in the
fuselage. Be sure the alignment pins are secure in the
wing halves before installing the wings. If they are not,
remove the pin and apply a small amount of thin CA into
the tube socket and reinstall the alignment pin.
 Step 3
Carefully slide the remaining wing panel onto the wing
tube that projects from the fuselage. The fit may be tight;
use caution when inserting the wing panels onto the wing
tube and fuselage.
 Step 4
Secure the wing panels using the 1/4-20 x 2" nylon wing
bolts.
 Step 5
Insert the stabilizer tube into one of the stabilizer
halves. Remove the covering to expose the hole for the
stabilizer tube bolt.
