OK- that makes sense to me , but what about this situation that I think every KR builder has run into. At the aileron control linkage to the aileron control horn to get full travel with out binding I found that I need a washer between the control horn and the rodend bearing and then to be able to have a large washer on the outside of the rodend bearing It needed 2 more small washers first so the rodend does not bind on the large washer. In other words here is the order-- bolt head,washer, control horn, 2 washers, Large washer, castle nut with cotter pin. That puts a total of 4 washers in this system. I could replace the 2 washers with a aluminum spacer but that dose not seem practical to me. I know others have had to do something at these points to get the geometry to work. I just don't want to be rebuilding in front of an inspector Thanks Joe Horton, Coopersburg, PA. joe.kr2s.buil...@juno.com
