Went flying today, waited for the usual full GPS lock and the two sets of flashing green. Worked fine. Only went up for a few minutes on a full charge. I landed and powered down and some dude comes walking over and of course wants to see it work. I had to go but I told him I'd hover it for a second so he could see it. I wasn't going to wait for a whole startup sequence just for a ten second hover at five feet. Powered up, eased the left stick up and KABOOM! LIFTOFF! The thing shot straight up into the air like a rocket and RAN for it. Must've climbed about 80ft. and then just chose a direction. I found it in the woods about 200yds away. Don't do that.
