Problem is when quad take off it spins in circular motion(yaw axis) on its path(autonomous flight) and i want stop tried adjusting trim on radio but no change, have checked motors spin direction and props , re calibrated escs all checked ok.  
pixhwak 2.1 cube black.  
firmware 4.0.1(latest).

Any log?

Does it spin when flying in manual modes?

Check that all your drone arms are perfectly levelled.  
This kind of behaviour can occurs when an arm is twisted and a propeller not really horizontal

If you post a link to the .bin log we will probably be able to see that shows motor mounts or arms twisted and motor torque unable to overcome the physical yaw bias
