Control Throws
 1. Turn on the transmitter and receiver of your
model. 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 toward the
bottom of the transmitter should make the airplane
elevator move up.
 3. Check the movement of the ailerons with the
radio system. Moving the aileron stick right should
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.
Aileron
High Rate
Up: 11/32-inch 9mm
Down: 11/32-inch 9mm
Low Rate
Up: 9/32-inch 7mm
Down: 9/32-inch 7mm
Elevator
High Rate
Up: 5/8-inch 16mm
Down: 5/8-inch 16mm
Low Rate
Up: 15/32-inch 12mm
Down: 15/32-inch 12mm
Rudder
High Rate
Right: 19/32-inch 15mm
Left: 19/32-inch 15mm
Low Rate
Right: 7/16-inch 11mm
Left: 7/16-inch 11mm
Measurements are taken at the inner or
widest point on the control surface.
These are general guidelines measured from our own
flight tests. You can experiment with higher rates to
match your preferred style of flying.
Travel Adjust and Sub-Trims are not listed
and should be adjusted according to each
individual model and preference.
We highly recommend re-binding the radio
system once all the control throws are set. This will
keep the servos from moving to their endpoints
until the transmitter and receiver connect.

Check your Radio
Before going to the field, be sure your batteries are
fully charged per the instructions included with your
radio. Charge the transmitter and motor battery
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, run the motor. With the
model securely anchored, check the range again. The
range test should not be significantly affected. If it
is, do not 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).
Check all the control horns, servo horns, and clevises
to make sure they are secure and in good condition.
