"While mine was not nearly that repeatable, I agree that it seems at least very similar to what I experienced. Unfortunately, I was never able to diagnose the problem, and because of that I have retired that drone indefinitely. I would LOVE to get…"

"I had a strange motor activation which occurred under different circumstances, but also while the quad was supposed to be disarmed (right after initial battery connection in my case). I do have dataflash logs of my incident (included). I'm sorry to…"

"I did have two modes which had simple enabled. I am almost certain I was not in one of these, but even if I was, I definitely did not switch modes (I didn't even have the transmitter in my hand, since I was plugging the quad in). The PWM range was…"

"Well, this was the first flight of the day, and I'm certain neither of the batteries were connected before I set up in the field, so I think the chance the APM had remained on is negligible.

Could a gross level electromechanical failure include an…"

"That's a interesting thought, but I don't believe that the external battery was ever connected for this flight. I had only flown with it a few times, but I had been connecting it after the main battery. This external battery was a separate circuit…"

"First off, THANK YOU for taking the time to read through the logs and give me some feedback. I can't remember for sure where the throttle was when I plugged the quad in. It might have been midway but I tend to doubt this. The transmitter was on at…"

"(Shameful, shameful bump.) I'd love to get some feedback on this, if I can't figure out why the quad did this I will likely have to retire this APM for fear of a repeat."

"Update: I have upgraded to 3.0.1, remounted the APM so as to reduce compass interference, and checked to make sure compass and vibration issues are under acceptable levels (they are).

I took some test flights today, and got two issues, both of…"
