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.
8. Anytime power is to be removed from the radio system, it’s important to shut
down power in the aircraft fi rst. Otherwise, the aircraft could become out of
control and cause a safety hazard! Move the throttle stick and throttle trim
lever 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.
