ESC (Electronic Speed Controller) is the board that controls the speed for the motors. each motor has a board. so you have one or more failing.
as for a compass i would look on ebay for someone that crashed and it selling parts. but be careful when removing the top body to replace DJI left like zero slack in the plug wire for the GPS |
