i have had it back out flying 5 times, no problems. very strange
it has never hit the ground but it has crashed into pine trees twice.
i took off tarrot gimbal and gopro, just have spycam fpv cam left
it has done this at the same takeoff time 10-15sec, take off hover then by-by
every thing is dji including rc
thanks for info, i have a phantom4 so not going to spend much on 550
i have had this happen 2 times 30ft hovering then motors start raceing aircraft does a half flip to left and does not stop until the ground,
no rime or reason i had thougth the first time the nazav2m gps compas had came off
