I lost a Regal Eagle one time because the CA hinges on the elevators failed. I believe they were the Sig ones. All of the hinges failed, they did not pull out of the wood. I then conducted a little test. If you grab both ends of a CA hinge with 2 pair of pliers and try to rip them, you can't. Now wick a little CA on both sides of the hinge and try the same thing, they will rip. I used them for years with no problems on all sorts of prop planes including pattern planes, but I would never use them again on a jet.
