I have to dissagree with DR1Driver.
Epoxy, if used right, is stronger than CA in certain applications. Epoxy can flex where CA is rigid and a bit brittle.
I started off using epoxy and CA in high power rockets. I am talking about rockets over 3lbs and personally up to 11lbs than are capable of supersonic flight.
I have seen beginners in that sport use CA for their fins and watched the rockets turn into confetti.
I would never consider CA for any high stress application, that includes high power rocket construction (fins and engine mounting) and firewall, landing gear blocks and wing joints in airplanes to name a few.
