RE: control horn for pull-pull rudder
Yep yep. I have used Dubro's pull-pull kit in several planes, always good results and the adjustment is great to boot.
To my original post above, if I had my druthers, I'd rather have the pull-pull kit. That said, the double control horn thingy works well and I used it when I didn't have a kit on hand (impatient me).
