I have a weird behavior in loiter/poshold.
When i'm loiter and I want to yaw my copter, it's drifting backwards for about 3-4 meters and than will slowly go back to it's position where it started from.
Doesn't matter if I yaw right or left. It always "pulls back" a few meters and returns to "0" position.
In the pics I took from the log you can see that the Y is acting good, but the X looks like it's mirroring.
Can someone point me out the right way.
Thanks in advance.
