I have the Super Kraft control horns and they give me three pairs different sizes, short, med. & long. Which horns should I use for my pull/pull rudder, elevator and ailerons I am using the Du-bro super strength long servo arm for the rudder. I thought I should use the longest horns for the rudder but it is longer than the servo arm and doesn't deflect the full amount should I use shorter horns on the rudder?(if so where do I use the longest horns?)The horns are set up just behind the hinge line maybe a 1/16th I also get some slack in the cable which I can blame Ackerman for
