RE: Don Muddiman Flying Machine
oh,and you don't need super heavy cloth, 2 oz. cloth is usually plenty, brand is irrelevant (or at least it seems to me, I have never had an issue with any brand). I also use carbon fiber strips when building a Q500, Hots, or Flying machine type of plane just for a bit more rigidity to the wing. I use a few thin strips between the sheeting and foam on a foam core wing, or on the spars of a built-up wing. It does wonders for strength.
