Default RE: Ball links for Rudder horh?

Dave, point taken.

Sport, I know of other systems that do something similar, but not with a ball per se. MK products makes ball bearing linkages that center the load on the horn and dubro and others have linkage setups that center the load. These systems are designed for large planes. All of these products will use a machine screw as the control horn which must be securly mounted in a block that is then inset and glued into the control surface.

Another method I've used before is to install two control horns side by side. Put the ball in between and run a bolt thru the whole mess. No side load that way.
