Pre-Flight
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.
Adjusting the Engine
 Step 1
Completely read the instructions included with your
engine and follow the recommended break-in procedure.
 Step 2
At the field, adjust the engine to a slightly rich setting at
full throttle and adjust the idle and low-speed needle so
that a consistent idle is achieved.
 Step 3
Before you fly, be sure that your engine idles reliably,
transitions and runs at all throttle settings. Only when this
is achieved should any plane be considered ready
for flight.
Range Test Your Radio
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. If using a gasoline engine, check the range first
with the engine not running and note the distance. Next,
start the engine. 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.
