Has anyone had a problem with the threaded rod staying square with the rudder? No matter how much I tighten the "cone" nuts the rod will move around without to much effort. I tried to scuff up the mating surfaces but that didn't help. I was thinking maybe a thin rubber washer might work. Any ideas or am I missing something. Thanks. Oh, I'm not using the stock setup because it is a "new improve" as they call it which does not conform to the airfoiled rudder. I'm using the du-bro heavy duty pull pull setup.

It has been suggested to me by many to either drill a hole in the rudder and install a hardwood dowel for the pull-pull to go through, or to brace the rudder with pieces of light ply. Thanks for this post, I was going to cut a corner, but now I won't.

That was the thought I had as well. a Hard spot in the rudder to hold the control horn in place.

When I build the plane from a kit or plans I install a hard point with either dowel or a ply block so I can tighten the rod in without squishing the balsa. On an ARF I sometimes cut it and do the same or if I take a short cut I make two over size squares out of 3/32 ply and place it on both sides of the rudder. In a pinch I have hardened around the screw hole with thin CA and gotten away with it but it's not the best fix. Balsa is very soft and it just can't hold the screw unless you harden that area.

Sorry for the delay in getting back. I installed a wooden dowel in the rudder and now it's as solid as a rock, no movement at all. Thanks for the help.
