Update on the CA hinge failure topic for those of you that may be interested. I had some help and used a different solution than the Robart Hinge Points or the Dubro pinned hinges. Here is the thread update at the bottom of page two. Hope this helps some of you avoid the hassle I experienced with CA hinges in a Pitts with a DA 50.
