Had my P2V+ for almost a year, didn't fly it very much but I was just getting comfortable flying it... and then I had my first crash. After 15 mins of good flying I wanted to bring it in and land. About 30' in the air, suddenly I lose control and it comes down hard. It didn't appear to lose all power. The rotors were still turning with power and I certainly had plenty of battery left. A guy who seemed knowledgable about Phantoms was watching and saw it happen, he came over and said it looked like a "not a number" error. Don't know what he meant by that. Any idea what happened here? Physically, nothing looks damaged, but the gimbal goes a little crazy when I fire it up now. The ribbon connector looks good. All four rotors rotate seemingly without any problem. Is this self-repairable, or does it look like I'll have to send it in for repairs? I'm probably over the warranty by now which really stinks. Video of the crash: Gimbal failure: Thanks!
