Netters Have some difficulty with the aileron spars that I have floxed into the wing (Diehl RAF-48 skins). Thought I had them held straight when I glued them in, but when I screw the hinge in place, it's in a bind, not real bad, but not as free as I think it should be. Thinking of re-doing the spars and using rod ends like the Dr. Dean method I used for the elevator. And than I could wait the leading edge of the aileron for counterweight. Any thoughts or problems with that idea. How many rod end bearing would be sufficient to the equal full length of the piano hinge? Pete Klapp
