Assuming that yaw gain is high enough.
Ok! i will do that!

I have only focus on the wookong and its components, and havent check the motors.

Im experiencing a problem, a couple of seconds after the takeoff the craft start yawing (spinning) to the right by itself, i dont do any rudder commands. Even when i try to compensate by applying full left rudder the hexa will respond very slowly, it dosnt stop spinning at the instant, how it should be when i apply full rudder to the left. And some other times it wont respond at all!

At least i am having this issue a few meters above ground so i have never had some accident nor crash.

I have try many things: calibrating the compass, adjusting the YAW gains, offsetting the compass to the opposite side of the turn (left) an in the same side of the turn as well (right), and so far i havent find any solution.

I cannot attatch the fly log file, but if anyone is interested just PM me, or email me at andreas.ddelnogal@gmail.com

I almost forgot, i am using Firm V 5.22
Make sure that all your motors are level and not canted. The GPS puck needs to be pointing forward, the lead to the front. Recheck your COG and then your X, Y and Z settings based on the COG.

Improvement

Well i have checked the motor aligments and they were wrong, but i already fix it, i put the gps/compass in the dji pole as well.

Bottom line, the flight attitude improve in great way. There some issues remaining but i think that i just have to work harder on the motors.

I`ll keep posting
