I have used the CA hinges in my GP Wagstaff, GP 25% Giles, H( 80" Cap with no problems over many flights. However, after the 3rd flight on my GP Eagle three of the hinges on ailerons failed. They didn't pull out, they just broke. I landed without problem and promptly ordered Robart hinge points. My hinge points came with a jig for alignment. I won't fly it again until all hinges are changed out.
