That is cool! When you talk about design you always share a lot of experience. Thanks for keeping it "real." LOL!! It looks like you could do all your lay ups on a table then vacuum bag it down and then build the aircraft from the pieces. Do you cut your carbon pieces before (as fabric) or after you mix/cure the pieces? Marske's manual has the calcs for doing fabric covered composite wings. The "Irv Culver" airfoil (RIFPIB) would be fine for this performance envelope. The air will forgive you. When you "ballpark " structures do you usually start with a three layer 45-45-0 or is this excessive for carbon?
