I build all kinds of stuff from foamies to balsa ( when i mean build i really mean repair)

I find epoxy too brittle specially if you want to build something up.

I use foam safe thick ca glue and that seems to work the best on foam to foam. The glue gun just melts it.

I use 5 min epoxy on wood to wood or wood to anything.

Athough epoxy on smooth plastic doesn't seem to hold up.

I do crash once in a while so i thought maybe i should use something with a little flexibility in it.
