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.
