Yesterday I lost my P2, Hero 3+mini, iOSD, etc. and my H3-3D gimbal flying on the North part of the West Coast of the South Island in New Zealand I was flying at a deserted beach in nearly 0 wind, 2nd flight of the day. Calibrated compass before flights, I had 10 satellites locked, all flashes on P2 showed good. The P2 was only 200m away, about 50m up in the air. I switched the IOC to home lock to bring it back while maintaining the mountain view I wanted with my camera. I was watching the camera view when I noticed the altitude raising rapidly. I turned the IOC off and put it into Atti mode, throttle held to minimum, but it kept going up, completely unresponsive. Hit the FS switch, but by that time it was over 350m and climbing. I never saw it again. This is my second fly-away this year. I've seen a lot of posts by people who say it is always pilot error. That is bullsh*t. I would love some insight. Is the Naza system simply inconsistent? Are the Phantoms simply a waste of time and money? I don't read about s900 or s1000 fly-ways. Can anyone help me here?
