receiver to set the desired failsafe positions.
If your transmitter allows it, enable the throttle cut feature. Always engage throttle
cut before approaching the aircraft.

Some of the terminology and function locations used in the iX12 programming
may be slightly different than other Spektrum AirWare™ radios. The names
given in paranthesis correspond to the iX12 programming terminology. Consult
your transmitter manual for specific information about programming your
transmitter.
* Flap programming values may vary slightly. For your initial flights use the
recommended flap travel settings provided in the Flaps section and adjust
the flap travel to your preference on subsequent flights.
