I will be Monokoting the plane. Someday I would like to get set up to paint, but it will not be for this build. Last night after my post I started thinking that I have the numbers incorrect on the wing cores. I know the weight of the skins, and thought I remembered the weight of the cores. It seems like I added 40 to 130 and forgot the other skin... If 130 grams sounds right for one core, then the two skins were 32 and 40, and that puts the glue at roughly 40... either way I guess the result is the same... 240 and 238. But it would be nice to know, because the Gorilla glue was ultra easy to use, and the combat guys say it isn't any heavier than West Systems epoxy. Thank you for the tip on the wing tips.
