Arducopter destabalizes & crashes every time

Hi !

I built my F450 quadcopter with APM 2.8, 1400kV bldcs and 30A ESC, internal compass and external gps.

I’ve done everything from internal compass, accelerometer, and preflight callibrations.

APM itself is mounted a little high and on a copper PCB shielding to avoid Magnetic Interference.

But everytime i lift-off in STABALIZE MODE, the quad spins around and crashes.
Default parameters and no unnecessary settings changes.

Just can not find the cause of this issue. Can somebody guide me please.

Did you Test the motor order?

hi !
i did solve the issue, the problem was with the CCW and CC connections.
