Transmitter Setup (BNF)
IMPORTANT: After you set up your model, always rebind the transmitter and 
receiver to set the desired failsafe positions. 
The GEAR Channel (CH 5) controls the retractable landing gear. The FLAP Channel 
(CH 6) controls the fl aps. If you are using a 6 channel transmitter, The FLAP 
Channel (CH 6) can be used to toggle SAFE select. With the values listed below 
it will turn SAFE on for half and full fl ap potions and AS3X will be on for no fl aps 
position.
To use the fl ap channel for the SAFE select switch the values must be set to +100 
and -100 and the speed set to 0 temporarily to assign the safe switch in the fl ap 
system menu. Then change the fl ap systems values back to the listing in the TX 
setup. See the SAFE Select Switch Designation section of this manual to assign the 
switch for SAFE select.
Dual Rates
Attempt your fi rst fl ights in Low Rate. For landings, use high rate elevator.
NOTICE: To ensure AS3X technology functions properly, do not lower rate values 
below 50%. If less control defl ection is desired, manually adjust the position of 
the pushrods on the servo arm
NOTICE: If oscillation occurs at high speed, refer to the Troubleshooting Guide for 
more information.
Expo
After fi rst fl ights, you may adjust expo in your transmitter.

 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 parenthesis correspond to the iX12 programming terminology. Consult 
your transmitter manual for specifi c information about programming your 
transmitter.
* Flap programming values may vary slightly. For your initial fl ights use the 
recommended fl ap travel settings provided in the Flaps section and adjust the 
fl ap travel to your preference on subsequent fl ights.
