Failsafe in QGC "Return Mode"


In the RC loss failsafe trigger option is QGC. I have selected the option Return Mode. And, in my RC transmitter, I have put the throttle value -100%, which means if RC loses, the motors will be turned off. In such a scenario, which action will be executed? Will the drone return to the launch position, or the motors will be turned off, and the drone falls down immediately?

It depends whether your Rx switches off PPM to signal a connection loss or whether it keeps outputting a signal.

If you want to trigger the PX4 failsafe on low throttle you can configure it as explained in Radio (Remote Control) Setup | PX4 User Guide, and Parameter Reference | PX4 User Guide.
