Range Testing the Radio
 1. Be sure to range check your radio before each
flying session. This is accomplished by turning on your
transmitter with the antenna collapsed. Turn on the
receiver in your airplane. With your airplane on the
ground and the engine running, you should be able
to walk 30 paces (approximately 100 feet) away from
your airplane and still have complete control of all
functions. If not, don’t attempt to fly! Have your radio
equipment checked out by the manufacturer.
 2. Double-check that all controls (aileron, elevator,
rudder and throttle) move in the correct direction.
 3. Be sure that your transmitter batteries are fully
charged, per the instructions included with your radio.
