First im very newbie about multirotor and pixhawk or pixhack, what i got before this build just cx20 open source but i will learn much if u want to help me.
i dont know what happen in my quadcopter build, when i takeoff is alway going back or any direction wanted to flip so i cant hover and make my blade broke 2 times.
I really sure i was check everything, calibration esc one by one or all at once, check direction motor, check esc wire to my pixhack, calibration accel, calibration compass, calibration radio and pitch reserve, balance propeller and is very weird for me who first build quadcopter and i already try to reset my pixhack.
but the problem i found is, when i motor test in mission planner, Motor test C will make my motor C and D spinning together, and Motor test D same as C it will make my motor C and D spinning together, A and B is normal. so i already swap my motor and not work still same, i swap my esc too still same.
i dont know why, please help this moron :(
