Have a few questions, as I am finishing up my LT-40 taildragger conversion. The Du-bro tail assembly I am using, the control horn that is inside the fuse (which the wheel axed goes up through) has a small set screw on it to connect the control horn to the axel. The control horn (I assume) is nylon, and the set screw is steel. After getting the set screw engaged, what can I use to lock it in place to keep it from vibrating out? I read my GP Thread lock bottle, and it indicates to NOT USE on plastic. I have no idea of the effect. What should I use? CA?

Also, my rudder servo, when you look directly down at it, it seems to be askew by like 5 degrees. Everything works good, but the control horn just does not seem to be totally paralell. I cannot figure out any way to adjust it by that little bit it is out. Do I just live with it?

Everyone's help is appreciated.
