I wish my CA reaction only lasted 3 days.

My building is mostly with Elmers Carpenters glue, including wing ribs and spars. Its far stronger than the balsa anyway. I use 30 minute epoxy for firewalls and landing gear blocks, and pin them inplace where possible. I use gorilla glue to glue in weights inside the fuselage, particularly tail weight if necessary. I like the way a small amount can be used to essentially encase the weight in foam inside the fuselage. Also works well for wing tip weights. I also use gorilla glue for hinges and pins where the expansion is desirable. I don't waste time with 5 minute epoxy. For fiberglassing and fuel proofing, I use the 20 minute finishing epoxy. It also works very well for giving a high gloss finish to painted plastic and fiberglass parts (cowls and wheel pants).

I'll use Foam Safe CA for thread hardening and some quick repairs. So far the foam safe CA hasn't induced the CA reaction.
