Section 1: Landing Gear and Rudder Installation
Required Parts
• Wheel assembly (2) • Landing gear
• Landing gear strap (4) • Tail gear assembly
• Rudder • Fuselage
• 5/32-inch wheel collar w/setscrew (2)
• 3mm x 10mm sheet metal screw (8)
Required Tools and Adhesives
• Hex wrench (supplied) • Petroleum jelly
• Phillips screwdriver: #1, #2 • Thin CA
• 30-minute epoxy • Sandpaper
• Drill bit: 1/16-inch (1.5mm) •Pin drill
o Step 1
Use a small flat screwdriver to remove the cap from the
outer wheel hub as shown.
o Step 3
Slide the inner wheel hub onto the landing gear. The wheel
collar is then installed by tightening the setscrew onto the
flat spot on the axle using the supplied hex wrench.
Note: Make sure to use threadlock on the

11
Page 12
Section 1: Landing Gear and Rudder Installation
Step 9
Attach the landing gear to the fuselage using four landing
gear straps and eight 3mm x 10mm sheet metal screws
and a #2 Phillips screwdriver.
Step 10
Use sandpaper to roughen the wire so the epoxy will have
a rough surface to bond to.
Step 11
Apply a small amount of petroleum jelly to the top and
bottom of the tail gear bushing. Work the jelly into the
bushing to prevent epoxy from entering the bushing and
locking the tail gear wire.
Step 12
Use 30-minute epoxy to glue the tail gear bushing into
the fuselage. Make sure the bushing is pressed tight in
the fuselage, and has been slid down toward the bottom
of the fuselage as far as possible.
12
Page 13
Section 1: Landing Gear and Rudder Installation
Step 13
Use a pin drill and 1/16-inch (1.5mm) drill bit to drill
a hole in the center of each hinge slot in the fin and
rudder. This will provide a tunnel for the CA to wick
into, providing a better bond between the hinge and
surrounding wood.
Step 14
Step 15
Slide each of the hinges into the rudder until the T-pin is
resting on the hinge line of the rudder.
Step 16
Test fit the rudder onto the tail gear wire, guiding the wire
into the pre-drilled hole in the rudder.
Place a T-pin in the center of each of the three CA
hinges. This will help in centering the hinges when they
are installed.
13
Page 14
Section 1: Landing Gear and Rudder Installation
Step 17
As you slide the rudder onto the tail gear wire, slide the
hinges for the rudder into the slots in the fin. The rudder
should fit tight against the fin, and should not bind at the
balance tab when the rudder is in operation.
Step 18
Once you have checked the fit of the hinges and tail
gear wire, remove the rudder from the fin. Apply a small
amount of 30-minute epoxy on the tail gear wire and into
the hole in the rudder to secure it in the rudder. Repeat
Steps 16 and 17 to place the rudder back into position.
Step 19
Remove the T-pins from the hinges. Apply thin CA to
both sides of the three hinges. Allow the CA to cure
(without using accelerator) before proceeding to the
following steps.
Note: The CA must be allowed to cure without
the use of accelerator. Using accelerator
will not allow the CA to fully soak into the
hinge, and could produce a poor bond
between the hinges and surrounding wood.
Step 20
Once the CA has fully cured, gently pull on the fin and
rudder to make sure all the hinges are glued securely.
14
Page 15
Section 1: Landing Gear and Rudder Installation
Step 21
Move the rudder right and left a number of times to
condition the hinges.
Step 22
Secure the tail wheel using two 1/16-inch wheel collars
and two setscrews. Tighten the setscrews using the
supplied hex wrench.
Note: Make sure to use threadlock on the
setscrews to prevent them from vibrating loose.

16
Page 17
Section 2: Aileron and Flap Servo Installation
ooo Step 4
Lightly sand the servo mounting blocks on the edge where
they will be glued to the servo cover. This will allow the
epoxy to hold onto the block, providing a more secure
bond between the cover and blocks.
ooo Step 5
Use 30-minute epoxy to attach the two mounting blocks to
the servo cover. Use clamps or tape to hold the blocks in
position until the epoxy fully cures.
ooo Step 6
Transfer the locations for the servo mounting screws onto
the servo mounting blocks using a pencil.
ooo Step 7
Drill four holes for the servo mounting screws using a
drill and 5/64-inch (2mm) drill bit.
17
Page 18
Section 2: Aileron and Flap Servo Installation
ooo Step 8
Apply 2–3 drops of thin CA into each of the holes to
harden the surrounding wood. This will make the screws
more secure and prevent them from vibrating loose.
ooo Step 9
Use the screws supplied with the servo and a #1 Phillips
screwdriver to secure the servo to the mounting blocks.
oo Step 10a (aileron servos only)
Remove the supplied servo arm from the aileron servo.
After centering the servo, attach a standard double arm
using the screw supplied with the servo. Use side cutters
to remove the portion of the arm that does not extend
beyond the servo cover.
oo Step 10b (flap servos only)
Remove the supplied servo arm from the flap servo. After
centering the servo, attach a long servo arm (JSP98060)
using the screw supplied with the servo.
18
Note: When installing the horn on the
flap servo, set the throw on the radio
to the center position for the flaps.
Page 19
Section 2: Aileron and Flap Servo Installation
ooo Step 11
Pass the servo extension through the wing and into the
bay for the flap servo. Use four #2 x 3/8-inch sheet metal
screws to attach the servo cover to the wing.
ooo Step 12
Continue to pass the aileron extension through the wing.
Use tape (or glue) to secure the aileron extension to
the top sheeting of the wing. This will prevent it from
interfering with the operation of the flap servo.
ooo Step 13
Use a pin drill and 5/64-inch (2mm) drill bit to enlarge
the outermost hole in the servo arm to accept the
pushrod wire.
ooo Step 14
Slide one of the pre-bent 3
the hole drilled in the previous step.

Attach the tail rigging with the long and medium tabs to
the bottom of the fuselage using two #2 x 1/2-inch sheet
metal screws. The longest tabs go to the front, while the
medium length tabs go to the rear.
Step 5
Step 6
Attach the tabs to the top and bottom of the stabilizer
using four 4-40 x 1/2-inch socket head screws and four
4-40 lock nuts. Leave the bolts loose enough so the tabs
can be rotated.
Carefully bend the remaining rigging tabs using pliers.

Step 7
Connect the rigging to the tabs on the stabilizer.
Step 8
Attach the remaining cables to the fin using two
4-40 x 1/2-inch socket head bolts and two 4-40 lock
nuts. Connect the clevises to the tabs on the stabilizer
at this time.
Step 9
Once all the cables have been attached, go back and
tighten the bolts holding the tabs at the stabilizer. Do
not crush the wood of the stabilizer by over-tightening
the screws.
Step 10
Adjust the flying wires so there is equal and light tension
on each wire. Make sure that the stabilizer and
fin have not been twisted during the tensioning of the
flying wires.
Step 11
To keep the rudder and elevators from moving, and to aid
in the installation of the linkages, use low-tack painters
tape to tape the rudder to the fin, and the elevators to the
stabilizers, at this time.

Page 47
Section 10: Cowling and Canopy Installation
Step 6
Use medium CA to glue the pilot seat in the cockpit. Note
that the seat does fit slightly forward of the rear of the
cockpit as shown.
Step 7
Use canopy glue to secure the canopy to the fuselage. Use
low-tack tape to hold the canopy in position until the glue
fully cures. If you are planning on installing a pilot figure
then install now before attaching the canopy.
Section 11: Recommended Center of Gravity (CG)
An important part of preparing the aircraft for flight is
properly balancing the model. This is especially important
when various engines are mounted.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location
for the Piper Pawnee 40 is 3
leading edge of the wing against the fuselage. If necessary,
move the battery pack or add weight to either the nose
or the tail until the correct balance is achieved. Stick-on
weights are available at your local hobby store and work
well for this purpose. The range for the Center of Gravity
7
is 2
/8– 3 3/8 inches (73mm–85mm).
Note: The Center of Gravity can also be
measured as 6
3
/4 inches (171mm) behind the
cuff of the wing against the fuselage, with a
range of 6
1
/2– 7 inches (165mm–178mm).

Section 12: Control Throws
The amount of control throw should be adjusted as closely
as possible using mechanical means, rather than making
large changes electronically at the radio. By moving
the position of the clevis at the control horn toward the
outermost hole, you will decrease the amount of control
throw of the control surface. Moving it toward the control
surface will increase the amount of throw. Moving the
pushrod wire at the servo arm will have the opposite
effect, moving it closer to center will decrease throw,
and away from center will increase throw. Work with a
combination of the two to achieve the closest or exact
control throws listed.

Section 13: Pre-Flight
Charge both the transmitter and receiver pack for your
airplane. Use the recommended charger supplied with
your particular radio system, following the instructions
provided with the radio. In most cases, the radio should
be charged the night before going out flying.
Check the radio installation and make sure all the
control surfaces are moving correctly (i.e. the correct
direction and with the recommended throws). Test run
the engine and make sure it transitions smoothly from
idle to full throttle and back. Also ensure the engine is
tuned according to the manufacturer’s instructions,
and it will run consistently and constantly at full throttle
when adjusted.
Check all the control horns, servo horns and clevises to
make sure they are secure and in good condition. Replace
any items that would be considered questionable. Failure
of any of these components in flight would mean the loss
of your aircraft.
Section 14: Adjusting the Engine
Step 1
Step 3
Completely read the instructions included with your
engine and follow the recommended break in procedure.
Step 2
At the field, adjust the engine to a slightly rich setting at
full throttle and adjust the idle and low-speed needle so
that a consistent idle is achieved.
Before you fly, be sure that your engine idles reliably,
transitions and runs at all throttle settings. Only when this
is achieved should any plane be considered ready
for flight.
Section 15: Range Testing Your Radio
Range check your radio system before each flying
session. This is accomplished by turning on your
transmitter with the antenna collapsed. Turn on the radio
in your airplane. With your airplane on the ground, you
should be able to walk 30 paces away from your airplane
and still have complete control of all functions. If not,
don’t attempt to fly! Have your radio equipment checked
out by the manufacturer.
