My fault, this one... Last time I flew a couple months ago I redefined the flight modes so I could try the non-standard ones like circle, etc. And the way it works - you guys all know this- is that the flight mode switch and the RTL switch combine to give you 6 total modes (3 times 2). For me to get RTL I'd have to be in mode 3 and then RTL. But it had been so long I had forgotten that.
I was flying my last flight only about 15 feet off the ground (grass) and went to try RTL. But I had forgotten how I had it set up. I was flying in Loiter but the way I had it set up RTL switch sent me to stabilize. The throttle was low so the thing just dropped out of the sky. Broke a blue arm and the leg on one of the black arms wrenched out breaking the mount area on the arm. So 2 new arms.... luckily no harm to gimble or GoPro.
Anyone have a handy dandy way to label or otherwise remember the mode setup when you make changes?
