RE: Lets Try To Mold A Moldie!
Yeah, Dave's using a layer of 3oz, then the 6oz and carbon in higher stress areas, and then another layer of 3oz over the whole thing. It doesn't seem like much, and is a lighter layup than Jim Allen's used on our Proud Birds, but it's been more than enough. The "round" shape and compound curves of the airplane add a lot to the strength so you don't need as much actual structure.
