I was trying to fly a used Phantom 3 that I bought yesterday. I went up for around 15 seconds until my drone started loosing control. It was flying randomly at high speeds until it crashed into the ground. While this happened speed error and compass error appeared into my log, it also shows a cell deviation in red as well as changing into ATTI mode. According to my log it reach speeds of up to 117 mph, but I do not know how accurate it is, since I was not able to see it when it drifted away. After the crash the gimbal broke. I tried to fly it without the camera and everything was normal.
Any help would be greatly appreciated,
