Range Testing the 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.
Preflight
Check Your Radio
 Before going to the field, be sure that your
batteries are fully charged, per the instructions
included with your radio. Charge both the
transmitter and receiver pack for your airplane.
Use the recommended charger supplied with
your particular radio system, following the
instructions provided with the radio. In most
cases the radio should be charged the night
before going out flying.
