RE: experince on Dynafite Butterfly needed.
On second thought, you've got a point--I need to qualify my statement about epoxy. White glue joints are strong for all wood to wood applications IF they are properly done. Read the directions on the bottle, and make good joints. White glue is not gap filling, or only slightly so. Epoxy is more tolerant of joints that don't quite fit right.
It's a very common mistake of beginners to think they need to use epoxy to make strong joints. Often they will build up glue filets with it thinking they will make it even stronger--the end result is a plane more prone to crash damage because of excess weight. But careful use of epoxy in limited areas will not build up too much weight.
I prefer white glue because it is lighter, less messy, quicker to use, it soaks into the wood a little, it gives excellent strength, and sands reasonably well (I like Weldbond--I think it sands better than some others). I don't like the fumes of CA and its refusal to be sanded.
