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 :(

Two motors spinning at once during Motor Test is strange. That's one thing I can say never happened.
Absolutely yes, i never find this issue in internet or forum.
i try hard but still dont know what happen.
maybe this issue who make me cant takeoff.
very frustrated lol, but i still learn about this problem.
my goal for make this bird can fly. lol
this video seems problem like me, after calibration esc my motor normal spinning but after plug in battery again my motor increasing power itself.

Don't worry too much about the increasing power by itself, it does that some times as it hasn't taken off the ground it increases power to try do so. It shouldn't do it in flight.
please check my log, when i thorttle up and test pitch or roll to the full my pixhack was restart.
not happen was going wrong maybe my battery.

but my quadcopter when takeoff always going random direction and making flip.
is too extreme and i dont know why this happen.
and what do you think about PWM, can i change that value?
Can you share the log of that test?
i just using motor test now, should i test with propeller again and takeoff?
or i hold my quad when takeoff?
Try without props moving side to side and observe what's It´s react, don´t try to fly until you solve the issue; and share the log.
As Dyer says you have to found why the two motors spin at the same time; perhaps you can ask about your issue where you bough? if not a harware malfunction?
this is my log, new issue when i thorttle up and test pitch or roll to the full my pixhack was restart. what happen?
my battery?
please check :(
