E-flite Extra 260 3D Profile - Manual (Page 40)

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.

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.
