I'm back!!! Couldn't find anything in the 540 thread about how to install the aileron linkage. If any of you have some please post them for me. I can't figure out where the horn is supposed to be positioned on the aileron. I have one glued on but the horn is not right and will have to be repositioned[] Trying to drill the holes for the horn once the aileron is glued on is a pain. I like to line it all up, remove it and drill it on the press to keep the holes perpendicular to the surface. Oh well, this is my first tapered wing plane.
