I am rebuilding my rudder due to reaching my personal crack limit at ends of the stiffeners. Many years ago in the old RVAtor issues there was someone who added a small rib at the trailing edge of the rudder and elevators that tied the stiffeners together. I can't find the article. Does anyone have access to the 25 Years of the RVAtor and would be willing to look up that article and send it to me? Or has anyone done something similar and have pics?
