I like Titebond II the best of the three. "I" isn't waterproof and "III" is brittle - hasn't failed yet but I like using II. Cleans up nicer (I put it in medicine cups and apply with an acid brush). It's also nice to be able to wipe up any excess with a damp rag.

When I need epoxy I use 30 minute for all cementing (and thinned with acetone for fuelproofing). If I'm laminating fiberglass I use epoxy finishing resin. Takes even longer to set but I like the results better.

I use CA for hinges and in gluing up wings. Hate the stuff but being able to frame up the wing and then just run along hitting the joints is still near miraculous for me. Thiose little pipette applicators are worth the added expense as it eliminates the tip problems with CA bottles. Guess I better try this hinge glue.

I was helping an Explorer post and we built four Sig LT-40s using only Titebond II (the host site would not allow epoxy or CA glue). We did sneak the models out to CA the hinges and fiberglass tape the wing roots with epoxy; but otherwise all Titebond II. One group used two bottles, another used 1/2 of one bottle. All the models flew and (to my knowledge) held up in service. A good testement.

I also use Aileen's Tacky Glue. A Vinyl glue similar to Canopy ("56" ) glue but much cheaper.

Gorilla glue foams too much and is a mess. The "Sumo" glue, similar but less foaming, may be a good choice for wing bolt blocks and other "internal" attachments like sevo trays and fuselage frames.

And I like CA gell for repairs. I trust it more than CA and it fills cracks nicely.
