Good day According to the manual you should do a compass calibration when the drone is drifting. Is this correct? Can I also just ask where is the compass situated in the runner 250 Pro? I have a similar problem, after the drone fell twice. More landing hard on grass than anything else After that the drone is drifting The compass does not want to calibrate - Left red light flashing quickly, Right led does not come on during horizontal anti-clockwise turning Also I cannot get into GPS mode, red light does not flash when flying in manual mode Is it perhaps possible that the GPS is damaged with the nard landing?
