I use two radio Aurora 9 and Turnigy 9x with Open 9K firmware. I was trying to adjust Fail Safe to throttle channel, but unsuccessfully.
I do everything as instructed ( http://plane.ardupilot.com/wiki/arduplane-setup/apms-failsafe-function/ ) but the throttle channel value is not reduced.
Thanks in advance!

For stock Turnigy 9X with the stock 9X8Cv2 receiver the failsafe setup procedure is this:
-Set the transmitter to PPM in SYSTEM SETTINGS->MODEUAT/MODULATION->PPM
-Set FUNC SETTING->E.POINT->THROTTLE to 120%/120% (This changes the maximum throw up&down. protip: move throttle stick to change value for up/down...)
-Set FUNC SETTING->SUBTRIM->THROTTLE to -120 (sets the midpoint lower, so that the failsafe value goes to less than 1000
-Set FUNC SETTING->FAIL SAF->THR->F/S 000% (This sets the failsafe (transmitter off) value to 0%, which goes -to <1000 since we changed the midpoint/endpoints.
-Adjust your throttle trim and APM/multiwii/etc. failsafe thresholds so that the failsafe signal value is lower & failsafe is correctly activated in your autopilot. Poke, Test, poke and test. Don't rely on the default values!
Note: My Turnigy transmitter&receiver are a few years old from Hobby King. Your results may vary. Tested on [SYSTEM SETTINGS->TYPE SELECT->ACRO] model type. Not sure if everything are the same for GLIDE&HELI. Also the Turnigy is a cheap-ass system, consider something better for anything valuable&dangerous. :)
