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.
