While building, I heard or read from what I considered a reliable source that the rudder should have three hinges, not two as per plans. Three on elevator is adequate. Using a thinner nylon / plastic replaceable bushing on the plans type aluminum hinges would require removing less of the hinge metal. I checked my memory at the airport the other day and confirmed that Cessna uses 1/4" steel threaded rod (may be rolled threads, not cut) with rod end bearings for aileron actuation. More than adequate for the KR.
