In the thread on the GP Christen Eagle, there was a discussion regarding failure of CA hinges, and not limited to just the Eagle. Well yesterday, I was going over my LT40 trainer and found a broken CA hinge. I'm about ready to install hinges on my GP Christen Eagle and will not use the CA hinges. Any comments regarding using GP's nylon pinned hinges? (The control surfaces have already been cut for CA hinges.) Any other suggestions? I'm a little nervous about using Robart hinges, they seem tough to get lined up properly.
