Hey Paul,
The Whizard came with a wing center section. It has a spar slot for a piece of 1/8 X 1/8 spruce. You glue that in, then wrap the joint with some kind of light fabric and glue. I think that it was originally tissue and white glue. When you find your article, run the plans through an enlarging copier and trace the airfoil. You can then cut a wing from foam or build one from balsa. If it was me, I might try the balsa because I like balsa better. If I remember correctly, the wingspan is 42 inches. By the way, the ME 109 has tapered wings, but the Whizard has constant chord wings. I would be happy to send you a set, but I don't have any. All I have is a couple of thousand tapered ones. The Whizard would fly great with tapered wings, but I would still recommend adding a center section, because if you reduce the area too much it won't fly like a Whizard any more.
Does anybody know if Ace foam wings are once again commercially available?
