Sorry guys but I too have just experienced two sets of hinge failures.

I have a Hanger 9 Cap 232 120 size Matt Chapman Edition that I had just completed a few 3 weeks ago. On the 3rd flight I lost all the hinges on one of the ailerons. I was able to land her with no damage so I took her home and replaced all the hinges on that aileron. Two flights later and I lost all the hinges on one of the elevators. Again I was able to bring her down with out any problems. The hinges I was was using are the pre-cut Great Planes CA hinges. New bottle of thin CA and the fit of the hinges were just a tad bit from flush.

The problem was not that the plastic separated from the fiber ( maybe on two hinges) but what had happed was the hinge itself split into two halves. Since that last incident, I have not flown and had just received my order of nylon pinned hinges. I don't think I want to chance another failure.

Question: What is the best method for installing nylon pinned hinges? The ones I have are the Great Planes Medium nylon hinges. Some people say that I could just use medium CA and everything will be fine. I tried looking how to get epoxy into the slots but I just don't have any type of syringe that can fill up the slot. I am worried that if I use epoxy, I won't be 'bonding' enough of the hinge surfaces to the trailing edge and control surface. Any help or 'tricks' would be appreciated.
