Just finished a Dynaflyte Decathlon, 89" WS, used about 1 1/2 oz of medium CA and about 1/2 ounce of thin. Some alphatic (Elmer's Pro Bond) not a whole lot, just for the sheeting on the wing, and epoxy for the firewall. I use a glue syringe for the wood glue, I have had it for years, but I think you can still get them in the hobby shops. Saves a lot of glue and puts it right where you want it.
Joints that fit well do not take a lot of glue and hold better. The wood will break before the joint separates.
