Scott at SWB is the pull pull master IMO. I actually think pull pull is a pain in the butt. There is always some former rubbing on the cables, or the cables are rubbing on the slots, the ARF rudder is hinged crooked from the plane mfg, the cable slots have to be really long for straight cables, the cables hit the elevator servos, many more things too long to list. Then there's me drilling the rudder horn hole crooked. All sorts of things can go wrong.

Anyway, on my big ARF's pull pull rudder is necessary for balance but I don't really enjoy setting them up because it just never seems to turn out perfect or even close. Hopefully I will nail the perfect pull pull rudder setup one of these days.
