I know of at least three new wing designs that have been discussed on this exchange recently which are using Joe's airfoil. I am intrigued enough now to want to experiment with the airfoil myself. Does anyone have a link to the coordinates, or at least a graphic of the airfoils profile? Mahalo! Brian Courtice Maui RCSE-List facilities provided by Model Airplane News.
