Experiencing a weird problem. Was flying 250Pro then I switched from manual to GPS. And it started ascending even though I pulled the throttle all the way down. Tried return to home and it still the same. Believe me or not. It flew 920m away. At that moment I thought of giving up. But somehow I managed to bring it back by Lock the motors and let it drop then turn on the motors. But I broke one leg of it trying to Land. Seems to me even on manual mode when you give full throttle (Left stick) and take the stick all the way down the motors wont slow down. Did the latest firm wear update thinking that might fix. But nothing has fixed. This was working fine before. Never had any issue. This was a sudden bug came from now where. Badly need help from you guys. Fed up of this drone already. Anyone else went through this problem ?
