easily becoming dislodged during normal  ight. It’s best to check the system with the
propeller removed from the aircraft.
1. Once all connections are made, check the general operation of the radio and
all other components before attempting a  ight.
2. Move the Tx throttle stick to the minimum (idle) position.
3. Turn on the Tx, and then the Rx.
4. Make sure all controls are operating in the proper direction. If any servo is turning
in the wrong direction, change the reverse setting for that channel.
5. With both sticks at center position, move the trim levers for the aileron, elevator,
and rudder channels so each respective control surface is perfectly aligned with
the main surface. For example: when the aileron trim lever is at center, it’s best
that the trailing edge of the aileron is aligned with the trailing edge of the wing
itself (not above or below the wing’s trailing edge).
6. Make sure that movements of the throttle stick result in an equal adjustment of
the throttle in the model. Depending on whether the model is electric or glow
powered:
a. Electric: con rm that when the throttle stick is at maximum position the electronic
speed control gives the appropriate indications (LED and/or audible indicators)
for full forward  ight. And, when the throttle stick is at minimum position the
electronic speed control gives the appropriate indications for “off” or no motor
rotation.
b. Glow: con rm that when the throttle stick is at maximum position the mechanical
linkage to the engine allows the engine to be at full throttle. And, when the
throttle stick is at minimum position and the throttle trim lever is moved to
minimum position, the engine stops completely.
7. Perform a range test as explained on page 39.
8. Anytime power is to be removed from the radio system, it’s important to shut
down power in the aircraft  rst. Otherwise, the aircraft could become out of
control and cause a safety hazard! Move the throttle stick and throttle trim to
minimum position to stop the glow engine or shut down the ESC. Once the
propeller has stopped rotating, shut off the ON/OFF power switch in the model,
and disconnect the power battery from the ESC in electric airplanes. Then turn
off the power switch in the Tx.
1. Once all setup procedures have been con rmed, and power has been removed
from the model and transmitter, prepare the model for  ight.
IMPORTANT: Be very careful to stay clear from
moving propellers and blades!!
2. Make sure the glow engine fuel tank has an adequate amount of fuel, or power
batteries for electric models are fully charged.
3. Move the Tx throttle stick to the minimum position, and then turn on the Tx power
switch. Turn on the power switch in the model or connect the  ight battery.
