Constant Yaw in Stabilized Mode & Sudden Climb in Position Hold

ArduCopter Copter 4.5
1

Hi everyone,

I’m experiencing a persistent yaw problem with my quadcopter running ArduCopter 4.5.7 on a Matek H743 flight controller. In Stabilized mode, the drone constantly yaws around itself, and in Position Hold mode, it initially didn’t take off but then suddenly shot straight up into the air.

I’ve attached a log file showing the behavior during the flight.
this is the Pos Hold mode:

and this the constant Yawing in Stab mode:

Any tips are appreciated, iam very new to ardupilot and kinda lost.

Use ArduPilot Methodic configurator to systematically address the issues, one by one

Btw, I dont know if related, my ESC is a T-motor F55A, i configured it with the Am32 configurator, but I wasnt able to calibrate it through the mission planner.
