I flew my P2V+ V3. 44 times before fly away. About 8.8 hrs or 528 min.
I was hovering about 150 ft making sure all was ok then right about when I hit the go button on a GS mission it went into ATT mode, lost all satellites and took off in opposite direction of where it should go. I now flipped the switch to ATT mode and back to GPS mode, nothing. Tried to steer it , nothing, hit the come home button, nothing. RTH switch, nothing.
I Found Phantom thanks to GPS tracker about 1/2 mile or more away high in a tree.. Got it back and checked camera footage and the camera cut off about half way thru flight, so did not get the crash on camera. It show it taking off going backwards and then about half way into flight turning around and going forward then video shut off . By looking at camera file dates, the flight I had just before the 'fly away' flight had the right file date. The 'fly away' flight had a file date of 12-31-2007. Seems like the phantom lost its brain for a little bit as it flew away.
When I went next to turn it on it had a MC Data Error, MCU IMU Calibration error. So I plug into Phantom Assistant and recalibrate then do a compass calibrate and now it flies again. The video file dates are now back to normal.
At the end of this video the screen capture part froze and the remaining few seconds is from the on board camera until it stop recording. Don't know why it stopped recording. Drone continued on flying for about 1/2 mile or so after recording stopped.
