I updated to FW 4.02 and noticed some changes in the failsafe setups. I wanted to test my setup in order to make certain everything was working. I use either an R/C link or a Joystick (through MP) to control my quad.
I set the new FAILSAFE parameter to “19” because I want to RTL when I’m using EITHER controller in STABILIZE or LOITER modes, and to continue on the mission when in AUTO mode.
In order to test, I tied my quad down and ARMED it in the STABILIZE mode. Without taking off (but propellers spinning), I shut off my radio. Immediately, Mission Planner reported that there was a radio failsafe and the quad was “disarming”. This surprised me, because I don’t remember it doing that before. The only thing I can think of is that the failsafe doesn’t operate normally before takeoff. But before I crash an expensive piece of equipment, I want to know for certain. So how DOES this work anyway?
