Disapointed to see that the steel pushrod fouls the edge of the openning in the rear spar at both limits of aileron movement. The max deflection of the aileron is within the limits set in the construction manual (Section 15) but you can alread see that the powder coat on the pushrod is being marred. Also, at max up deflection one of the rivet heads that secure the rod end "catches" on the edge of the opening - this worries me - I see potential for a jammed flight control. Its hard to see how this cannot have been a problem in every kit since there's not much latitude for positioning given that all the holes are prepunched. Anyone else have these issues ? g (Fuselage sitting in its crate calling my name.) ========================================================== Gerry Filby gerf@gerf.com Home: 415 239 4846 Cell: 415 203 9177 ________________________________ Message 2 _____________________________________ Time: 09:41:06 AM PST US From: "Richard Jones" Subject: Re: RV9-List: Aileron pushrod clearance --> RV9-List message posted by: "Richard Jones" Gerry: You must be right. I had this problem on Kit #90062. I opened the hole in the rear spar up a little. It's far enough out on the wing that stress should be pretty low.

Some have worked around the rivet catching by having the rod-ends welded on instead of riveted on. Enlarge the hole with a file until you remove enough material so that the push-rod doesn't interfere in any way.
