RE: comp-arf rudder wobble
Some guys also have found the air balancer to be too large. A few guys I know have cut a piece of the air balancer off and then attached it to the verticle stab, thus making the air balancer smaller and the verticle stab larger. It seemed to make a big difference according to the pilot. If I'm not mistaken, the Super Extra has a smaller air balancer that the 3.0 Extra.
