With the reaction wheel parts in recent versions being pretty darn powerful in comparison to the mass of the average rover, I've been using them to help keep my rovers from flipping, or at least flip them back over if they do. I've been trying to find a MechJeb option to help with this, and almost found one in the Smart A.S.S. "SURF(ace)" option; keeping Pitch and Roll at 0 will indeed keep my smaller rovers from flipping in most cases, but the Heading keeps trying to turn them. Is there some way to have MechJeb use the reaction wheels to keep my rover flat without it trying to change direction?
