I cannot get this to work. My setup is a Spektrum DX8 tx with AR8000 rx satellite plugged into a PX4 Pixhawk. The satellite just does not remember the low throttle setting ( 904 PWM - 150 Low throttle) when I go back to the 1100 PWM setting.
Are you rebinding the Rx and Tx when it is at low throttle.
Spectrum requires the bind to lock in the failsafe settings.
Yes, in two modes, normal and preset several times. When I turn off and turn on again the receiver with normal acceleration the receiver loses the low acceleration setting.
In fact the AR8000 is always saving the tx moment configuration.
