Found it. One of my frame arms was bent. This caused one motor to be out of alignment. Bent the arm, bubble level checked frame to all arms till perfect, and set motion compensation to 100.
Not more tipping and flys as smooth as glass. Will post a video soon. Cannot believe I didn't check this sooner. Did not for a minute think the arm could have been bent. Not the first time I forgot to check mechanical issues first.
More to come.
