This is one of those things I absolutely disagree with. There is NOTHING on your plane that is safe to fix with ANY epoxy at the field. Even 5 minute epoxy takes a full day to cure. For all the strength of 5 minute epoxy applied at the field you may as well take chewing-gum.

If your plane breaks in such a way that epoxy is required the best thing you can do (and the only safe thing), is to take it home and repair it there. Don't be tempted to fly a plane that has been repaired with epoxy in the previous 24 hours.

I can be a bit anal with some things, and this is one of them. Especially because this is the beginner's forum.
