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.

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.

saddle until they are.
6. Double-check the adjustments from Steps 1 through 3.
Use a felt-tipped pen to trace the outline of the fuselage
onto the top and bottom of the stabilizer.
7. Use a sharp hobby knife to cut the covering slightly
inside the lines drawn. Be very careful not to cut into the
underlying wood, as this will weaken the stab and cause
it to fail in flight.
26E-flite Piper Pawnee ARF Assembly Manual
Note: You can use a soldering iron instead of a knife.
This will eliminate the chances of cutting into the wood.
8. Apply a thin coat of 30-minute epoxy to the exposed
wood on the top and bottom of the stabilizer. Slide the
stabilizer back into the fuselage and clean up any excess
epoxy using a paper towel and rubbing alcohol.
9. Use a rotary tool and a 1/16-inch (1.5mm) drill bit
to drill a hole in the center of each hinge slot of both the
stabilizer and elevators. This provides a tunnel for the CA
to wick into, penetrating the hinge.
10. Locate three CA hinges. Place a T-pin in the center
of each hinge.
27E-flite Piper Pawnee ARF Assembly Manual
11. Slide the three hinges into the slots in the elevator.

do not bind during operation. Apply a few drops onto
each hinge. Make sure to apply the CA on both the top
and bottom of the hinge.
12. Slide the elevator into position on the stabilizer. The
T-pins installed in the hinges will help in keeping equal
amounts in the stabilizer and elevator.
Important: Do not use accelerator on the hinges. The CA
must be allowed to soak in and penetrate the hinge.
14. Gently pull the elevator from the stabilizer once
the CA has fully cured. This is to verify the hinges are
glued securely.
28E-flite Piper Pawnee ARF Assembly Manual
15. Flex the stabilizer through its range of motion a few
times to break in the hinges.
17. Place the fin in position on the fuselage. Trace the
outline of the fuselage onto both sides of the fin.
18. Remove the covering from the bottom of the fin using
the same technique used for the stabilizer.
16. Repeat Steps 10 through 15 to attach the remaining
elevator to the stabilizer.
29E-flite Piper Pawnee ARF Assembly Manual
19. Position the fin back onto the fuselage. Use a square
to check the alignment between the fin and stabilizer.
Lightly sand the bottom of the fin until the alignment
is correct. Use 30-minute epoxy to glue the fin to the
fuselage. Make sure to check the alignment periodically
to make sure it does not change position during the
curing process.

this entire joint with 6-minute epoxy.
Important: You must use threadlock on the two
3mm x 8mm machine screws to prevent them from
vibrating loose. If they do, you may lose control of
your aircraft. Make sure you use threadlock
on these two screws.

4. Remove the battery hatch from the fuselage. This is
accomplished by pushing the hatch forward and then
lifting the hatch up.
6. Turn on the radio system and plug the battery into the
speed control. Use the throttle to check that the motor
rotates counterclockwise when viewed from the front. If
not, follow the directions included with your speed control
to change the direction of the motor rotation.
Important Information About Your Brushless ESC
Make sure your ESC brake is programmed to Off. Also,
be sure to use an ESC with the proper low-voltage cutoff
and it is set correctly for the batteries you are using.
Note: Never check the motor rotation on the bench
with the propeller installed. The plane could move and
cause serious injury. Always check the motor without the
propeller to avoid injury.
7. Cut and tape a piece of card stock on both sides of
the fuselage to indicate the front edge of the fuselage.
5. Install the battery in the fuselage using the 8-inch
(204mm) hook and loop straps.

Important Information About Your Propeller
It is also very important to check to be sure the
propeller is balanced before installing onto the shaft. An
unbalanced propeller may strip the gears or cause poor
flight characteristics.
Note: If it is necessary to enlarge the hole in the
propeller, make sure to check the balance of the
propeller afterwards.

They can be turned over (top to bottom) if they do
not align with the holes in the wing and fuselage.
Secure the strut to the fuselage using a 2mm x 12mm
sheet metal screw and #1 Phillips screwdriver.
Control Throws
1. Turn on the transmitter and receiver of your Piper Pawnee.
Check the movement of the rudder using the transmitter.
When the stick is moved right, the rudder should also move
right. Reverse the direction of the servo at the transmitter if
necessary.
2. Check the movement of the elevator with the radio system.
Moving the elevator stick down will make the airplane
elevator move up.
3. Check the movement of the ailerons with the radio system.
Moving the aileron stick right will make the right aileron
move up and the left aileron move down.
4. Use a ruler to adjust the throw of the elevator, ailerons
and rudder. Adjust the position of the pushrod at the control
horn to achieve the following measurements when moving the
sticks to their endpoints.
Note: Measurements are taken at the widest point on
the surface.
7. Secure the struts to the wing using two 2mm x 12mm
sheet metal screws and #1 Phillips screwdriver.

Range Test Your Radio
1. Before each flying session, be sure to range check your
radio. This is accomplished by turning on your transmitter
with the antenna collapsed. Turn on the receiver in your
airplane. With your airplane on the ground and the
engine running, you should be able to walk 30 paces
(approximately 100 feet) 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.
2. Double-check that all controls (aileron, elevator, rudder
and throttle) move in the correct direction.
3. Be sure that your transmitter batteries are fully charged,
per the instructions included with your radio.
44E-flite Piper Pawnee ARF Assembly Manual
After the first flights, the CG position can be adjusted for your
personal preference.
Preflight
Flying Your Piper Pawnee ARF
Check Your Radio
Before going to the field, be sure that your batteries are fully
charged per the instructions included with your radio. 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.
Before each flying session, be sure to range check your radio.
See your radio manual for the recommended range and
instructions for your radio system. Each radio manufacturer
specifies different procedures for their radio systems. Next, start
the motor. With the model securely anchored, check the range
again. The range test should not be significantly affected. If it is,
don’t attempt to fly! Have your radio equipment checked out by
the manufacturer.
Note: Keep loose items that can get entangled in
the propeller away from the prop. These include
loose clothing, or other objects such as pencils and
screwdrivers. Especially keep your hands away from the
propeller.
Double-check that all controls (aileron, elevator, rudder and
throttle) move in the correct direction.
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 motor and make sure
it transitions smoothly from off to full throttle and back. Also
ensure the engine is installed according to the manufacturer’s
instructions, and it will operate consistently.
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.
Ensure you have set the model up correctly and have the CG set
per the instructions. Taxi into the wind and set the throttle trim so
the motor idles with the prop spinning. You will need about 200
feet to take off so ensure you have plenty of room. We fly at the
local club field instead of at a park with the Piper Pawnee. It
is a substantially larger model than a park flyer and has much
more mass. Do not use flaps for your first takeoff. Power up
slowly but smoothly while steering the model with the rudder
and begin your takeoff roll. You will find the model accelerates
out quickly and the tail will come up when it is ready. After
about 100 feet and while at full power, apply up elevator in a
smooth motion until the model lifts from the ground.
Once in the air you will find the Piper Pawnee is in its element.
Straightline flight is easy as well as high-banked turns. This
plane grooves like no other 15-size electric on the market today.
Aileron rolls are smooth and precise. Loops are strong and
large. The Piper Pawnee will pick up speed very quickly and
can fly at a brisk pace if you so choose. It is very leisurely in
the air at around 5/8 throttle. Once you are up and have the
model trimmed out, climb to a safe altitude and put the flaps
down. Set them for both the mid and full rate and note for any
trim changes. Have your helper make note of any significant
trim changes to the elevator and then set up to land.
Set up to land on the downwind leg and select full flaps. You
will find you will need to carry a small amount of power when
flaps are deployed. Come around from base leg to final with
the nose pointing down at the runway, flaps full down. Adjust
power as needed, flying towards your touchdown point. At
about 2 feet above the ground and beginning to feel ground
effect, reduce power and maintain a flat glide slop until
touchdown on the main wheels occurs. The model enjoys tailhigh landings with full flaps all day long. You will be looking
like a pro in no time. If you elect to land without the flaps
deployed, a flared, three-point landing is recommended as your
best approach.
We hope you enjoy many happy flights with your new E-flite
Piper Pawnee.

2007 Official AMA National
Model Aircraft Safety Code
GENERAL
1) I will not fly my model aircraft in sanctioned events, air shows
or model flying demonstrations until it has been proven to be
airworthy by having been previously, successfully flight tested.
2) I will not fly my model higher than approximately 400 feet within 3
miles of an airport without notifying the airport operator. I will give
right-of-way and avoid flying in the proximity of full-scale aircraft.
Where necessary, an observer shall be utilized to supervise flying
to avoid having models fly in the proximity of full-scale aircraft.
3) Where established, I will abide by the safety rules for the flying
site I use, and I will not willfully or deliberately fly my models in a
careless, reckless and/or dangerous manner.
4) The maximum takeoff weight of a model is 55 pounds, except
models flown under Experimental Aircraft rules.
5) I will not fly my model unless it is identified with my name and
address or AMA number on or in the model. (This does not apply
to models while being flown indoors.)
6) I will not operate models with metal-bladed propellers or with
gaseous boosts, in which gases other than air enter their internal
combustion engine(s); nor will I operate models with extremely
hazardous fuels such as those containing tetranitromethane or
hydrazine.
RADIO CONTROL
1) I will have completed a successful radio equipment ground range
check before the first flight of a new or repaired model.
2) I will not fly my model aircraft in the presence of spectators until I
become a qualified flier, unless assisted by an experienced helper.
3) At all flying sites a straight or curved line(s) must be established
in front of which all flying takes place with the other side for
spectators. Only personnel involved with flying the aircraft are
allowed at or in front of the flight line. Intentional flying behind the
flight line is prohibited.
4) I will operate my model using only radio control frequencies
currently allowed by the Federal Communications Commission.
(Only properly licensed Amateurs are authorized to operate
equipment on Amateur Band frequencies.)
5) Flying sites separated by three miles or more are considered safe
from site-to-site interference, even when both sites use the same
frequencies. Any circumstances under three miles separation
require a frequency management arrangement, which may be
either an allocation of specific frequencies for each site or testing
to determine that freedom from interference exists. Allocation plans
or interference test reports shall be signed by the parties involved
and provided to AMA Headquarters.
Documents of agreement and reports may exist between (1) two
or more AMA Chartered Clubs, (2) AMA clubs and individual
AMA members not associated with AMA Clubs, or (3) two or
more individual AMA members.
6) For Combat, distance between combat engagement line
and spectator line will be 500 feet per cubic inch of engine
displacement. (Example: .40 engine = 200 feet.); electric motors
will be based on equivalent combustion engine size. Additional
safety requirements will be per the RC Combat section of the
current Competition Regulations.
7) At air shows or model flying demonstrations, a single straight line
must be established, one side of which is for flying, with the other
side for spectators.
8) With the exception of events flown under AMA Competition rules,
after launch, except for pilots or helpers being used, no powered
model may be flown closer than 25 feet to any person.
9) Under no circumstances may a pilot or other person touch a
powered model in flight.
