Over the weekend I was flying my Phantom 3 advanced and there was electrical line interference and it flew into branches about 15 ft off the ground and crashed! everything looked fine, but the gimbal makes a grinding sound and the camera turns but doesn't line up in correct spot! my imu calibration keeps failing saying unknown error! It sounds like a gears is off in the gimbal motor but I wasn't sure whether I should take the screws out because that may void the warranty(If the crash didn't void it already
)
Any help on what I should do would be greatly appreciated!
