KR> aileron linkage bearing ends. elevator hinges per plans or double up on hinges
Hi Dean, I'll add that the quantity of hinges as designed are fine, However I am using Bronze bushings in the aluminum hinges to prevent wear. I have heard stories of sloppy controls due to the bolt hinge holes being worn and elongated. I used bronze bushings from the hardware store, some are staright( the inner hinge member), and I used some flanged(outer -overlapped-hinge member . The bolts keep the bushings captive. I'll try to post pics soon.

KR> aileron linkage
My Acro Sport had bent pushrods like you are describing so they would clear the bottom of the rear spar. To me the linkage rod off the bellcrank could have been made slightly longer so you would have had a straight pushrod though Fred Johnson Reno, NV Larry wrote: I have seen a couple of KRs where this linkage (the rod) was bent to accomodate the proper angle for that plane. I am not saying that this is the best thing to do, just saying that I have seen that done before. I am not sure if it matters, but I don't think I would bend mine unless it was absolutely necessary. Mark is right, usually this linkage is about 6 inches long on a plans built system.

From: Mark Langford n5...@hiwaay.net Since the rod was aluminum, it might have been 1/4-28 threads, now that I think about it. Somebody's probably got a pair of these somewhere...

I'll go one better, what about these? http://www.mcmaster.com/#rod-ends/=98sk3x they have right and left hand threads so one simply turns it to adjust the proper alignment of the ailerons. Granted, it would need to use 1/4 rod bearings, but if you use the aluminum ones they sell, you are saving even more weight. Just a thought Fred Johnson Reno, NV Mark L wrote: The short answer to your question is 6061-T6 aluminum. I'm not really qualified to answer this, since my ailerons are completely different from what the plans call for, but at the time I built my plane, Rand Robinson was selling what looked like a short linkage with rod end bearings on each end (and I think the housings on those were aluminum), joined by a short aluminum rod that was threaded 3/16 on each end. The whole thing was maybe 5" (that's probably in the plans), it was very light, and was almost certainly a specialty item made just for that application. Maybe Steve Glover sells those these days, but you turn down your own version of the center member if you had a lathe, the experience to run it, and the time to do it. And then there's locating the lightweight rod end bearings, but I'm sure they're available from somewhere...
