I found out that I really had to tighten up the pull-pull lines if I wanted to get 3D travel on the tail controls. This makes it hard on the elevator design if you just use packing tape and light ply for the hinge. I plan to use CA hinges on all control surfaces next time. They really worked well on the ailerons and they help zero the control surfaces perfectly when you release the sticks.
I went with some very thin music wire. I then cut up a small control rod tube and glued four 1/4" pieces of them in line back to the rudder. Same thing as the elevator. It seems to work out just fine. I set my Edge up the same way. I'm just waiting on a motor before I maiden the Edge. I used some CA hinges on the Edge and my Citabria. I've used the packing tape and found myself taping more than flying.
I have to agree with you on the way you described the Bipe. The Citabria flies alot like a full scale plane. I love the way I can turn it on a dime with rudder. I can't wait to try the F-18..
