Well my Sig stunter (can't remember which model but its in the same range of the Super Chipmunk) was never a great flyer in outsides. So I was reading up about the Rabe rubber which I have on a stunter I purchased and decided to try it. So it works as designed i.e. right rudder on down and slightly less on up. Still have to try it. I have also put a OS46LA up from as well. Hopefully that will help line tension.
