Flying on a bright beautifully sunny afternoon. Using my iPhone, I went through 3 batteries, Needless to say it was a fun afternoon showing people what this thing could do. Unfortunately for me though, my f'ing iPhone audio switch had turned off. I was flying in someone's yard (at their request) taking pics of their house when all of sudden, I couldn't climb. I did everything I could to maintain some kind of altitude while trying to get it back to me. It was at rooftop level and almost back when it clipped (barely) the roof and was sent hurling to the ground into the grass. I couldn't figure out of the life of me what'd happen although I knew the symptom was a dead battery, I got NO visible warnings whatsoever on my screen and I'm assuming no audible warning because the iphone speaker was switched off. When I picked it up off the ground, I checked the battery and it was down to 1 bar. I only had a total of 15 min. flying time on that flight, maybe, but I can tell you this.....1/3 of that time was spent WAITING PATIENTLY for my P2V+ to DESCEND from a 500ft. altitude. The current update limits it to a PAINFULLY SLOW 6ft. fps descent. While that doesn't seem slow....from 500' or more, it's a long time. A connector on the controller came off of the board totally and it stopping anything to do with firing up the motors. It lights up, but won't spin up. DJI promptly returned my call this morning and told me repair times are running a month. wtf. Nothing I can do at this point than send it in.
