E-flite Stearman PT-17 15e ARF Assembly Manual

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.

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.

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.
