Introduction
The Stearman PT-17 was a primary flight trainer used by
the U.S. Army Air Corps (USAAC) during World War II.
The PT-17 was a conventional biplane design with an
open, two-place cockpit to accommodate a student and
instructor, in tandem. The aircraft was constructed with
wood wings and a welded steel fuselage, all covered
with fabric. The plane became highly recognizable with
its biplane design and exposed radial engine. The
PT-17 was known as a rugged aircraft and an excellent
trainer. The PT-17 was designed by the Stearman
Aircraft Corporation and in 1934 Boeing purchased the
company. Boeing manufactured over 10,500 PT-17s and
when production ended it became known as the last
production military biplane built in the United States.

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 away from the propeller,
including loose clothing, or other objects such as pencils
and screwdrivers. Especially keep your hands away from
the propeller.
During the course of building your PT-17
ARF we suggest that you use a soft surface
for the building surface. A foam stand, large
piece of bedding foam or a thick bath towel
will work well and help protect the model
from damage during assembly.
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.

E-flite Stearman PT-17 15e ARF Assembly Manual
Center of Gravity
An important part of preparing the aircraft for flight is
properly balancing the model.
Caution: Do not inadvertently skip this step!
The recommended balance point for the PT-17 is
3-1/4 to 3-3/4 inches (82 to 95mm) behind the
leading edge of the upper wing. Mark the range for
the Center of Gravity on the underside of the upper
wing as shown. Interplane strut removed for clarity.
It will be necessary to assemble the model to a
flight ready state in order to check the center of
gravity location.
Parts Required
Assembled model Propeller
Motor battery
Tools Required
Felt-tipped pen Ruler
Stick-on lead weight
Ο 1. Install the motor battery.
Ο 3. Use a commercial balancing device or suspend
the model on fingertips within the recommended
center of gravity range to check the balance.
Ο 4. Due to the short nose moment of the Stearman
PT-17, between 2 to 4 ounces of nose weight will
be required. Determine the amount by temporarily
placing it on the dummy engine at the cylinder
location. When the appropriate amount is known,
remove the cowling and attach the weight inside at
the base of the dummy engine cylinders. Form a
curve in the weight prior to installation so that it
conforms to the interior of the cowling and does
not interfere with operation of the motor.

Ο 2. Install the propeller adapter and propeller. The
shaft of a screwdriver or Allen wrench can be used
to tighten the propeller nut.

Control Throws
Ο 1. Turn on your transmitter, plug in the motor battery
and switch on the receiver power. Make any clevis
adjustments necessary to center the control
surfaces, then secure all the clevises with the
silicone keepers.
Ο 2. Check the movement of the rudder using the
transmitter. When the stick is moved right, the
rudder should also move right.
Ο 3. Check the movement of the elevator with the
radio system. Moving the elevator stick toward the
bottom of the transmitter will make the elevator
move up.
Ο 4. 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.
Ο 5. Reverse the direction of the servos at the transmitter
as necessary.
Ο 6. Use a ruler to adjust the throw of the elevator,
ailerons and rudder. Adjust the travel volume or
dual rate in your transmitter to achieve the
following measurements when moving the sticks to
their endpoints.
Aileron
Up 3/4-inch (19mm)
Down 3/4-inch (19mm)
Elevator
Up 1/2-inch (13mm)
Down 1/2-inch (13mm)
Rudder
Left 1-1/2-inch (38mm)
Right 1-1/2-inch (38mm)
These are general guidelines measured from our
own flight tests. You can experiment with higher
rates to match your preferred style of flying.
Due to the lifting nature of the flat-bottomed airfoil,
your PT-17 may require a few clicks of down trim
for level flight, especially at higher power settings.
Preflight
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.
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.
226
Measurements are taken at the widest
point on the control surface.
Travel Adjust, Sub Trim and Dual Rates are
not listed and should be adjusted according
to each individual model and preference.
6
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 could mean the loss of your aircraft.

Flying Your Stearman PT-17 ARF
Safety, Precautions and Warnings
Age Requirements
Flying the Stearman PT-17 ARF is a bunch of fun and
will be enjoyable for all skill levels.
A very light wing loading and mild control throws make
for some enjoyable evening flying. Verify that your CG is
at the correct location as per the manual and that you
have your rates set up to your liking. Verify all control
throws are in the correct direction and the motor spins in
the correct direction also.
Point the model into the wind and add some throttle trim
until the motor begins to turn. This will be your flight idle.
Now, apply power slowly, the model may swing slightly
to the left so some right rudder may be needed on takeoff. You will find the model will become airborne very
quickly and at a low speed. This model excels at flying
slow and easy. Trim the model for level flight at half
throttle. In most cases the PT-17 will require a few degrees of down trim. The Stearman PT-17 ARF has plenty
of power with the E-flite Power 15 so you will only need
to use full throttle for maneuvering.
To land the Stearman PT-17 ARF, just reduce the throttle
to idle and feed in up elevator until the model settles into
a slightly nose-high attitude. Gently fly the model down
to the landing spot with a final flair at touchdown. You
will find the model will have a very short roll out. Both
wheel landings and 3 point landings are capable with
this aircraft. We hope you enjoy the Stearman PT-17
ARF as much as we do.
As the user of this product, you are solely responsible
for operating it in a manner that does not endanger
