I came across something I had not seen before.
This is looking straight down along the leading edge of the rudder on this RV-6A.
The builder folded the rudder skins along the line of prepunched holes, then rolled the skins tightly.
So, the normal rounded leading edge of the rudder is open instead. No pull rivets connecting the rudder skins together at the leading edge.
Same technique was used on the elevators.
All of the control surfaces swing freely and there is no binding, but it has me scratching my head as to why they did this, and is it airworthy? Airplane has been flying for over 20 years.
Thoughts?
