Correction to my post. I twisted the aileron horn up/down. And of course everytime I adjusted the aileron horn I adjusted the clevis to center it. Currently I have the Nexstar select rtf which includes the T4YBF so I can't adjust anything electronically.

fayrwerks: I currently have it on the outside arm of the 6-star. If there was a 4th hole I'd have no problem whatsoever. The 3rd/outer hole seems to not give enough throw.

bobby69smith: I initially checked to see if movement was hindered. I wiggled the arm for a bit to try and loosen things up. I will try and see if there is CA stuck somewhere.

I wish I had a programmable radio instead of all these gizmos I'll never use on the Nexstar. I'll continue to see what I can do to fix things mechanically. When measuring the throw should I zero the middle of the aileron or just pick the top/bottom as a reference point. Also, any proper place to do the measuring (end/middle)?
