I've been having a lot of problems lately, of getting my copter to hover properly, and to stop without drifting left.. It seems a lot of the problems reverberate back to the compass.. So for 22 bucks, I thought: why not replace it.. Does anyone know the process?.. I'm not sure exactly how the electrics are plugged into it, and how to remove them.. Do you pull it straight up from the chip, or what?.. Also, do you need a special non-metallic screwdriver to take the clamp off? ..Plus, do any other things have to be done, like recalibrating the IMU? Thanks..
