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.
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.
Before each flying session, be sure to range check your radio.
See your radio manual for the recommended range and
instructions for your radio system. Each radio manufacturer
specifies different procedures for their radio systems. Next, start
the motor. With the model securely anchored, check the range
again. The range test should not be significantly affected. If it is,
don’t attempt to fly! Have your radio equipment checked out by
the manufacturer.
Note
: Keep loose items that can get entangled in
the propeller away from the prop. These include
loose clothing, or other objects such as pencils and
screwdrivers. Especially keep your hands away from the
propeller.
Double-check that all controls (aileron, elevator, rudder and
throttle) move in the correct direction.
Check the radio installation and make sure all the control
surfaces are moving correctly (i.e. the correct direction and with
the recommended throws). Test run the motor and make sure
it transitions smoothly from off to full throttle and back. Also
ensure the engine is installed according to the manufacturer’s
instructions, and it will operate consistently.
Check all the control horns, servo horns, and clevises to make
sure they are secure and in good condition. Replace any items
that would be considered questionable. Failure of any of these
components in flight would mean the loss of your aircraft.
