I am using Pixhawk on a quadcopter. I had gone over all the wiki's about how to set up RTL. Flying in stabilize mode the other day to test RTL, I toggled the switch to RTL, and the quad just started to descend as if all motors had stopped working. I had to toggled the switch back to manual to gain control of the quad. Did I miss to set up any other advanced parameter?
Thanks for any feedback about this issue.
