Range Test Your Radio
 1. Before each flying session, be sure to range check
your radio. 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.
