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.

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.

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.

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 yourself and others or result in damage to the product or the property of others.
• Always operate your model in an open area away from cars, traffic or people.

Safety Do’s and Don’ts for Pilots
• Check all control surfaces prior to each takeoff.
• Do not fly your model near spectators, parking areas or any other area that could result in injury to people or damage of property.
• Do not fly during adverse weather conditions. Poor visibility can cause disorientation and loss of control of your aircraft. Strong winds can cause similar problems.
• Do not take chances. If at any time during flight you observe any erratic or abnormal operation, land immediately and do not resume flight until the cause of the problem has been ascertained and corrected. Safety can never be taken lightly.
• Do not fly near power lines.
Happy landings.
