A little tip I picked up somewhere that works really well with the wood control horns. With the pushrod in place on the control horn, drip a little CA into the oversize holes, let it fully cure, then move the surface to release the hold on the pushrod. Now you've got a zero-slop connection as the CA has filled in everything that isn't pushrod.
I was thinking about doing that too, but I was afraid it wouldn't release and I would break something, then I came up with this idea. I figured the wire would work like a bearing and wouldn't cause any binding and it did so far. I can always remove it and try CA if it fails later.
I just didn't want it to fly like an old car with loose steering, lol.
