Fly only in open areas to ensure safety. It is recommended
flying be done at AMA (Academy of Model Aeronautics)
approved flying sites. Consult local ordinances before
choosing a flying location.
PROPELLER
Keep loose items that can get entangled in the propeller
away from the prop, including loose clothing, or other
objects such as pencils and screwdrivers. Especially keep
your hands away from the propeller as injury can occur.
BATTERIES
Notes on Lithium Polymer Batteries
When used improperly, lithium polymer batteries are
significantly more volatile than alkaline or Ni-Cd/Ni-MH
batteries used in RC applications. Always follow the
manufacturer’s instructions when using and disposing of any
batteries. Mishandling of Li-Po batteries can result in fire,
causing serious injury and damage.
SMALL PARTS
This kit includes small parts and should not be left
unattended near children as choking and serious injury could
result.
Age Recommendation: Not for children under 14
years. This is not a toy.

Before Starting Assembly
Before beginning the assembly of your model, remove
each part from its bag for inspection. Closely inspect the
fuselage, wing panels, rudder and stabilizer for damage. If
you find any damaged or missing parts, contact the place
of purchase.
If you find any wrinkles in the covering, use a heat gun
(HAN100) and covering glove (HAN150) or covering iron
(HAN101) with a sealing iron sock (HAN141) to remove
them. Use caution while working around areas where the
colors overlap to prevent separating the colors.
Binding the Radio System
Before starting the assembly of your model, we recommend
preparing your radio system for installation. This includes
charging the transmitter and receiver batteries, as well as
centering the trims and sticks on your transmitter. If using
a computer radio, make sure to reset a model memory
and name it for this particular model. We also recommend
binding the transmitter and receiver at this time following the
instructions provided with your radio system.
Note: We highly recommend re-binding the radio
system once all the control throws are set. This will
keep the servos from moving to their endpoints
until the transmitter and receiver connect.

1. Locate the items necessary to install the aileron and
flap servos and linkages. You will also need the left and right
wing panels for this section of the manual.
2. Check the hinges in each wing panel to make sure
there is no excess adhesive that might prevent them from
moving. Use a hobby knife and a #11 blade to remove any
excess adhesive if any is found.
Note: Before beginning this section of the
manual, set the throws for the flap servo at the
transmitter to 0% in both the up and down positions.
This will center the flap servo, allowing you to
properly install the servo arm and linkage.
5Hangar 9 33% Pawnee 80cc ARF
3. Remove the aileron servo cover from the wing.
Align Perpendicular
Remove the cover for the flap servo at this time as well.
Make sure to mark the covers so they can be placed back
into the wing in the correct locations.
Hint. You can also use a JR Match maker (JRPA915)
to center the servos before installation.
4. Attach the servo arm to the servo after
centering the servo using the radio system. Make sure the
arm is perpendicular to the servo centerline. Also install the
grommets and brass eyelets in the servo.
7. Use medium grit sandpaper to scuff the end
of the servo mounting block to provide a better surface for
the adhesive.
5. Prepare both the right and left aileron servos
at this time. Note the position of the servo horn on the
servos shown.
8. Use 30-minute epoxy to glue the two servo
mounting blocks to the servo cover. Allow the epoxy to fully
cure before proceeding.
6. Place the servo on the cover, centering the
servo arm in the opening. Use a pencil to mark the location
of the servo mounting tabs.
6 Hangar 9 33% Pawnee 80cc ARF
9. Place the servo between the blocks. Position
the servo so there is a 1/32-inch (.5mm) gap between the
servo and cover. Use a pencil to mark the location for the
servo mounting screws on the servo mounting blocks.
10. Use a 5/64-inch (2mm) drill bit to drill the
four holes for the servo mounting screws.
11. Use a #1 Phillips screwdriver to thread
a servo mounting screw into each of the holes to cut
threads in the surrounding wood. Remove the screw before
proceeding to the next step.
12. Apply 2–3 drops of thin CA in each hole
to harden the surrounding wood. Allow the CA to cure
before proceeding.
13. Use four servo mounting screws and a #1
Phillips screwdriver to secure the servo in position.
14. Use string or dental floss to secure an
18-inch (457mm) servo extension to the aileron servo lead.
Note: Use a 3-inch (152mm) servo extension
when preparing the flap servos for installation.
7Hangar 9 33% Pawnee 80cc ARF
15. Use a 3/32-inch hex wrench and 1/4-inch
11/4-inch
(31mm)
open-end wrench to secure the ball end to the servo arm.
The servo arm is located in the inner hole, which is 11/4-inch
(31mm) from the center of the servo as shown.
16. Use a #1 Phillips screwdriver to thread a
2mm x 10mm wood screw into each of the holes to cut
threads in the surrounding wood. Remove the screw before
proceeding to the next step.
17. Apply 2–3 drops of thin CA in each hole
to harden the surrounding wood. Allow the CA to cure
before proceeding.
18. Tie the string to the end of the servo
extension. Use the string to pull the servo extension through
the wing to the opening for the flap servo.
19. Secure the aileron servo cover in the wing
using four 2mm x 10mm sheet metal screws and a #1
Phillips screwdriver.

20. Slide the 8-32 x 2
*Drawing not to scale
11/8-inch (28.5mm)
machine screw into the hole in the aileron. Mix a small
amount of 30-minute epoxy and apply it to the last 1/2inch (13mm) of the screw. Once the screw is in position,
Use isopropyl alcohol and a paper towel to remove any
excess epoxy.

/4-inch countersunk
21. Apply a drop of threadlock on the screw near
the aileron surface. Use an 11/32-inch open-end wrench to
tighten the 8-32 flanged nut against the wing to secure the
position of the screw.
24. Install the 4-40 x 3-inch adjustable link between the
control horn and ball end. With the servo centered, adjust
the link so the aileron is centered as well. Install the linkage
for both ailerons at this time.
22. Thread the short control horn on the screw
for the aileron until it is 11/8-inch (29mm) from the control
surface as shown. Use the short control horn for the aileron,
and the long control horn for the flaps.
25. Use a 4-40 x 2-inch adjustable link for the flap
servo installation. Adjust the linkage to achieve the mid-flap
position as shown. The servo horn can be angled toward the
leading edge to achieve mechanical differential.
23. Repeat Steps 2 through 22 to install the
remaining aileron servos, as well as the flap servos.
9Hangar 9 33% Pawnee 80cc ARF
Note: If you are using a 2-position flap
switch, still set the center position as a starting
point for the flap linkage installation.
26. Next, set the full-flap position Use the travel
adjustment to set the down flap position as shown.
27. Set the flap switch to the up flap position. Use the
travel adjustment to move the servo so the flap is aligned
with the wing as shown.
28. Install the remaining 4-40 x 2-inch adjustable link
for the opposite flap servo. Adjust the linkage so when the
transmitter is set to the up flap position, the flap is aligned
with the wing. The mid and down flap positions will then
match the opposite flap without any additional adjustments
to the radio.
29. (Optional) A clear lens and a string have been
provided if a lighting system is to be installed in the wing.
Use canopy glue to secure the lens to the wing to either
cover the opening, or to finish off the lighting system.

10 Hangar 9 33% Pawnee 80cc ARF
Note: Always use threadlock on metal-to-metal
fasteners to prevent them from vibrating loose.
2. Attach two wing strut mounts to wing using 4-40 x
1/2-inch socket head cap screw and 3/32-inch hex wrench.
3. Install the threaded wing strut fitting in the wing so
threads are flush to the wing surface. It will be at an angle
when installed so it aligns with the strut support.
4. Attach long wing strut to rear fitting with 4-40 x 5/8-
inch socket head cap screw and 4-40 lock nut. Use 1/4-inch
nut driver and 3/32-inch hex wrench to tighten hardware.
Make sure the airfoil on strut matches wing and jury strut
fitting faces to wing.
5. Attach short wing strut to front fitting with 4-40
