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 :(
i never flying this baby for one month because that issue :(

im very appreciate u want help me cala, thankyou verymuch :)
You say "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"
That's not right, each test should make one motor turn alone by itself, if two turn then something is very wrong. Somehow either two outputs are getting the same PWM value or there's a short or wrong connection somewhere causing the C & D to spin together.
i already swap esc or swap motor, and reinstall firmware but the issue about motor C and D still same.
and i was recalibrated my esc too.
how to fix this issue? or can i change the plug from 1-4 to 5-8 in my pixhak?
i was thinking about my APC SFP and SF propeller who have 2 ring, but one is loose and one again is not fit to my motor.
are this can make issue too?
i use loose ring but im sure nuts is very tight
please help me

Check if your horizon in mission planner is in the correct position if your copter is on a flat surface or if the horizon is crooked. Your radio trims are in 0?
im very sure is flat on horizontal posisition.
what do you mean 0 ?
That you didn't move your radio trims to any side but looks more that something incorrect assemble because your roll and pitch looks that can't follow desired ones or a mechanical failure.do you have another log?
First you have to fly in stab, then in alt hold and finally in Loiter; if you can´t fly in stab don't try other modes yet
yes thats true, sometimes i cant roll and pitch i dont know why.
i found that problem when my friend hold my quad and i check roll and pitch, is weird.
what do you think about this problem? my radio?
i just have 2 log again, 1 when i using gemfan and i found my pitch was reserve and this one when i using stabilize and loiter.

This log have mode err 6 and is strange your copter is in manual and FWA mode,that´s a plane mode check your modes, or perhaps better to start again, re upload firmware again and calibrate acc, etc again if you couldn't find another faster solution, go step by step again.
