As you can see above... there's a LOT of considerations in choosing which glue and where to use it.

CA is great for things that are hard to hold in alignment as the glue sets. And that's the only place i use it. Its expensive, an not wrth the cost for the speed gain in other locations.

CA is NOT very good for joining "Lite Ply." It wicks through the center layer too much. Yellow glue is far superior at giveing a good joint with minimal weight. ( and most lite ply box fuselages can be assembled just as fast using yellow glue as with CA... just let them sit a couple of hours after you get them assembled.)

Epoxy is the ONLY correct glue for installing firewalls in wooden structures. Vibration and fuel will cause other glues to fail, or at least crack, leading to fuel seeping in and causing serious problems. (2 hour epoxy should be painted over the entire firewall and inside wooden cowls, often with lite fiberglass to add strength.)

Then there's the new Polyurethane glues... GREAT for replacing epoxy in some areas. (but not for firewalls)

You can get a lighter structure with amazing strength by learning what glue to use where. Lighter planes fly better.
