I've built many of the large 1/4 scale planes including three cubs. On all I found that an aliphatic (usually Titebond) did 90 % of the glue jobs with 30 minute epoxy doing the rest. I rarely use CA but it does have an occasional use. A small container of CA usually last me through several kits and a year or more. It's best use is to harden the threaded portion of tapped wood for wing hold down bolts and hole outlines in thin plywood to prevent ply separation.
