SYSTEM CHECK AND OPERATION
WARNING! During all pre-fl ight preparations with the aircraft on the
ground, make sure the throttle stick remains at the minimum position
and do not stand the Tx upright on the ground. Carefully lay the Tx on its
back on the ground to prevent it from falling over and possibly dislodging
the throttle stick from the low position which would create a safety hazard. Make
sure all devices are properly mounted inside the model, and all wiring connections
are solid to prevent them from easily becoming dislodged during normal fl 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 fl 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 position of the reversing switch for
that particular 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 in the center
position, 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 airplane is electric
or glow powered:
a. Electric: confi 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 fl 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: confi 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 check.” The “range” is the safe operating distance from
the Tx to the Rx, and should be as far as you can clearly see the model.
With the assistance of another person, place the aircraft on the ground
and walk 100 feet (30m) away from the model. With the Tx pointed directly
at the model, operate the transmitter’s controls, and ensure the movement
of all surfaces is according to the movement of the transmitter.
