I try to yaw tune my 3kg quadcopter with 15 inch props. It has almost no response on yaw and moves only a bit. Almost impossible to fly by using yaw. Pitch and roll works good. I tried to tune by using Autotune which had no effect and manually I do not know where to start because the behaviour for yaw tuning is slightly different from pitch and roll.
Could somebody please give me some values I can start with for more responsible yaw movement?
I read that bad yaw response can be caused by compass problems. Can you plese check if this is the case?
