Hi folks,
Tell me to go away if this has been covered before. I know crash prevention has and I've read a bunch of posts but not seen anything like this.
Today while flying, a prop came off while I was about 40m up. On a quad this is pretty terminal.
As I watched it falling, throttle off but cartwheeling like mad, I was thinking. I still have 3 good motors and forms of lift. Why not use the good motor on the dead axis to try keep it level by speeding up / slowing down. Failing that, why not speed it up and cause it to flick right way up. As it tumbles over again, flick it the right way up. The idea is that it would spend more time the right way up than just random and you have a better chance of landing on your feet rather than head.
If it is not possible because of torque effects, cool, it was just an idea from a noob ;)
Cheers,
Crispin

Yeah, basically impossible. The yaw will be uncontrollable for one thing since you have for example 2 motors going CW and only one going CCW. And then it would be impossible to prevent pitching, because the motor opposite the failed one will make the copter flip anytime it is powered. The only way it could even begin to be possible is if it could go forward or reverse to try and get the copter upright. But... really it's just impossible.
I think the best that could be hoped for is if the AC2 recognized the condition, and killed the motors.
