Regular ole carpenters glue works good on balsa wood.

Gorilla glue works good, but it foams and spreads the joints out. You have to clamp and then wipe the foam off about 3 times within the first 20 minutes. After 20 minutes, it's done foaming and swelling. But who wants to fuss with every joint for 20 minutes? Not me.

White glue works, but it's not my first choice.

I use CA on everything but the landing gear mount, wing joint and firewall. CA works great. Just make sure you sand good and have nice tight joints. A tight joint is the best thing you can do for making an airframe last a long time. CA practically fuses the joints together. But, I know some guys can't handle the smell.
