Wow, that seems like a lot. I have the wing and ailerons all framed up on a 40 sized Mojo, built mostly with medium and thin CA. I have used about 1/3oz of medium and 1/2oz of thin. I have used some wood glue as well for gluing the center rib assembly together, but almost everything else was CA. A much better way to use the thin is with applicator tips (if you don't already use them), they make the flow much more controllable and precise.
