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.
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 engine and make sure it transitions smoothly from
idle to full throttle and back. Also ensure the engine is
tuned according to the manufacturer’s instructions,
and it will run consistently and constantly at full throttle
when adjusted.
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.
Before each flying session, range-check your radio.
This is accomplished by turning on your transmitter
with the antenna collapsed. Turn on the radio in your
airplane. With your airplane on the ground, you should
be able to walk 30 paces 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.
