The Piper Pawnee entered service in the late 1950s as one of
the first planes to be purpose-built for agricultural spraying and
dusting. While most have been retired from crop-dusting duty,
many are still on the job today towing advertising banners or
serving as towplanes for glider clubs around the world.
E-flite’s Piper Pawnee 15e ARF is a superbly detailed replica
of this aerial workhorse that flies every bit as good as it looks.
Its fuselage and wing outlines are exact-to-scale and perfectly
match the proportions of the full-scale Pawnee. Other realistic
touches include the prepainted fiberglass cowl and belly pan
as well as cockpit instrument gauges and a pilot’s seat. And
like its full-scale inspiration, the Pawnee 15e’s generous wing
area gives it exceptionally forgiving flight characteristics that
are perfect for newer pilots. You can even outfit the Pawnee 15e
with optional flaps and experience exciting short field takeoffs
and landings.
Using the Manual
This manual is divided into sections to help make assembly
easier to understand, and to provide breaks between each
major section. In addition, check boxes have been placed next
to each step to keep track of each step completed. Steps with
a single circle () are performed once, while steps with two
circles ( ) indicate that the step will require repeating, such
as for a right or left wing panel, two servos, etc.
Remember to take your time and follow the directions.

Notes Regarding Servos and ESC
WARNING: Use of servos other than those we recommend may
overload the BEC of the recommended Electronic Speed Control
(ESC). We suggest the use of only the servos we recommend
when utilizing the recommended ESC’s BEC, or the use of a
separate BEC (like the UBEC) or receiver battery pack when
using other servos.
Note on Lithium Polymer Batteries
Lithium Polymer batteries are significantly more
volatile than alkaline or Ni-Cd/Ni-MH batteries used
in RC applications. All manufacturer’s instructions
and warnings must be followed closely. Mishandling
of Li-Po batteries can result in fire. Always follow the
manufacturer’s instructions when disposing of Lithium
Polymer batteries.
Warning
An RC aircraft is not a toy! If misused, it can cause serious
bodily harm and damage to property. Fly only in open areas,
preferably at AMA (Academy of Model Aeronautics) approved
flying sites, following all instructions included with your radio.
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.

Threadlock File
Medium CA Adjustable wrench (2)
Note: We will assemble the landing gear and set them
aside until needed. This will reduce the number of parts
to track, yet keep the fuselage light to install the rudder,
elevator and radio system.
1. Locate the two axles and axle nuts, as well as the
landing gear. Use two adjustable wrenches to secure the
axles to the landing gear.
2. Use a file to create a flat on the bottom of the landing
gear wire. This provides a place to tighten the screws for
the wheel collars, making them more secure on the wire.
8 E-flite Piper Pawnee ARF Assembly Manual
3. Remove the hubs from the wheels. Note which is the
rear hub and which is the front hub.
4. Slide the rear hub onto the axle. With the 5/32-inch
wheel collar in the center of the axle, tighten the setscrew
using a 1.5mm hex wrench to secure the collar to the
axle. Make sure to use threadlock on the setscrew to
prevent it from vibrating loose.
9E-flite Piper Pawnee ARF Assembly Manual
5. Slip the tire over the rear hub. Insert the front hub
into the tire. Place a piece of music wire or hex wrench
through a hole in the front hub and into a screw hole in
the rear hub to help align the holes when inserting the
front hub in the wheel.
6. Use four 2mm x 15mm sheet metal screws and a #1
Phillips screwdriver to secure the front and rear hubs. You
can now install the hubcap onteh wheel.
7. Attach the landing gear covers to the landing gear
using four 2mm x 6mm machine screws. Make sure to
use threadlock on these screws. The front edge of the
covers will line up with the front edge of the landing gear
when installed correctly.
10 E-flite Piper Pawnee ARF Assembly Manual
8. Repeat Steps 2 through 7 for the remaining
wheel installation.
9. Slide the tail wheel onto the tail gear wire. Use a
5/64-inch wheel collar and setscrew to secure the tail
wheel. Remember to use threadlock on the setscrew to
prevent it from vibrating loose.
10. Use medium CA to glue the instrument panel into
the cockpit as shown.
11. Use medium CA to glue the seat into the fuselage.

2. Prepare the aileron servos for installation by removing
any unnecessary arms from the servo horns as shown.
Install any grommets or brass eyelets at this time as well.
The servos will have the arms installed opposite of each
other as shown in the photo.
3. Position the aileron servo on the servo cover so the
arm is centered lengthwise in the cutout. The arm will
align with the edge of the servo cover as well. Use a
pencil to mark the position of the servo on the cover.
1. Plug the aileron servos into the radio system and make
sure they operate and are centered as well.
12 E-flite Piper Pawnee ARF Assembly Manual
4. Use 6-minute epoxy to glue the servo mounting block
to the servo cover as shown. Allow the epoxy to fully cure
before proceeding.
5. Position the servo between the servo mounting
block. Use a pencil to mark the locations for the servo
mounting screws on the blocks. The servo should not
touch the cover to prevent it from absorbing vibrations
from the airframe.
6. Use a drill and 1/16-inch (1.5mm) drill bit to drill the
holes for the servo mounting screws.
7. Apply a few drops of thin CA to each of the
holes drilled in the previous step to harden the
surrounding wood.
13E-flite Piper Pawnee ARF Assembly Manual
8. Use a #1 phillips screwdriver to install the screws
provided with the servos to attach it to the servo
mounting blocks.
9. Secure a 6-inch (152mm) servo extension to the servo
lead using string or a commercially available connector.
10. Tie a weight to a 24-inch (600mm) piece of string
and lower the string into the opening for the aileron
servo. With the wing tip up, allow the weight to fall into
the wing, retrieve the weight through the hole near the
root of the wing.
14 E-flite Piper Pawnee ARF Assembly Manual
11. Tie the string to the servo extension and pull the
extension through the wing and out of the hole.
12. Secure the servo cover using four 2mm x 8mm sheet
metal screws and a #1 Phillips screwdriver.
13. Slide a clevis retainer onto a nylon clevis. Thread the
clevis onto one of the 4-inch (102mm) pushrod wires.
Note: Tape the extension to the wing so it does not fall
back into the hole.
