2 ounces of thin CA for 1 wing panel is too much. Use the thin to tack the parts together, and go back and use medium to fillet the joint. Using CA and epoxy only to build a model, you should only use about 1 to 2 ounces of thin, and maybe 2 ounces of medium for the whole model.

I agree that the tips on the CA bottles are way too big. to be able to use less try some of these. They pay for themselves with the amount of glues you save on the first bottle.

I use the tips on thin and medium CA, the pipettes I haven't found use for yet, and the Monoject syringe I use for wood glue. The T-pin keeps the wood glue from setting up.
