Drone (please complete the following information):
X680, had a nice flight in ArduPilot before.

Additional context
My guess is caused by he choosed DJI airframe, makes the MIN PWM too large, but why it shake like this, maybe I was wrong.

Flashed 1.10 and reset the PWM_MIN, now I think it's connected wrong motor wires.

Tested in stablized mode and checked the motor order, the quad continue lean to right side.
