Any of you have any suggestions to the cause? I sent it in to DJI and they said "Phantom did not malfunction, root of the cause was user error. It hit something midflight causing the Phantom 3 to crash down". However, it was in LOS the whole time and it never hit anything then all of a sudden at 266' it did a hard bank to the right and nose dived to ground without any control from my remote at all. Below is the details I submitted to DJI.
The Crash:
The aircraft performed great while at low altitude. I flew it left, then right, then backwards and then forwards with no problems at all. It was working fine while ascending, but all of a sudden it did a nose dive and I had no controls at all. Then it started saying ATTI mode, but it would not let me move it right or left or climb. Then it struck a tree and came to a rest upside down.
Details:
Altitude was 266' and distance was 611'
Take off was at 17:44 hrs. (sunset on this day was at 18:34 hrs.), the temperature was 75 F and winds were 8mph from 090 degrees (East).
Checked my Hover app to check the wind speed and direction and the Kp-Index, which was 2. I then turned off that app and placed phone in airplane mode. I performed my normal preflight equipment check list: inspected for cracks, no loose wires/screws/landing gear, nothing covering altitude sensors, props were secure and motor mounts were firm and battery was full and secured. Preflight check list: Placed aircraft on my take off/landing pad, connected my Iphone 6 plus to remote controller via USB cable, turned on the remote controller, placed phone in airplane mode, opened up the DJI Go App, then turned on the battery on the aircraft (all four green LEDs lite up), went back to the remote (7' away) waited for GPS link and then calibrated the aircraft, went back to remote verified 98% battery, 14 GPS satellites, and everything else on the equipment status was good and normal.
