Hi, My PiperSport, P1001073, has the SV32's on both roll and pitch and I have no slippage issues. If you still have this problem, I'll take a look at which hole the linkage is attached to and advise. I'm also running the AP from the D100 which is less agressive than the Skyview setup with the elevator. Some Skyview installations needed to move up to the 42's.
