Rudder Heim fitting adjustments - RV-4

[chris mitchell]

I am searching the plans for the setting for the Heim rod-end bearings in the rudder. They ought to be in drawing 7A (I don't have a 7 or 70B). I can see on 7A the drawings for VS 410, 411, 412, which would all be on the VS,but nothing about the rod ends on the rudder?? The equivalent distance on the elevators is 13/16" - see drawing 5A, bottom, just right of centre. Am I just not seeing it? I cannot find anything in the instructions either.....

Thanks

Chris

Set the hinge bearings to whatever is needed for complete and free travel of the rudder. In other words, trial fit the rudder to the vertical stab and adjust as necessary. The leading edge of the rudder should be as close to the stab spar as possible without introducing any contact that would inhibit full rudder travel.
