With increase throttle RCIN.C3 only two motors (C1, C2) increase thrust and after some time copter flip over. Thrust on C3, C4 do not appear with any tuning/param execution. What am I doing wrong?

Did you use Mission Planners Motor test to confirm the correct Motor Order and direction? This is almost always the reason a new build flips on take off.

Note the order it’s run in A-D

Yes of course. I’m use this scheme:

and mapvproxy motortest for testing motors with checking CW/CCW.

Solved. A/B/C/D in MissionComtrol are the same 1/2/3/4 in mavproxy motortest but NOT the same numbers on motor in picture.

Right. As I said, almost always the problem is motor order. 95% that 5% wrong Frame Type or Class.
