I'm thinking about building instead of ARFing it this time around for my second plane. I've been reading some build threads and all but here's my question. I've seen people using different glues for different purposes which caught me a little by surprise actually. Not that different glues don't have a different purpose but for example, why does everyone seem to use CA for wing ribs. I would have thought epoxy(being as strong a bond as it is) would be a select choice for that. In fact, I would have thought that if anything, you could use epoxy everywhere on the plane because of it's bonding strength.

If not, why and what do you use for what parts of the plane?
