I figured it out. A .dat file needs to be 1 unit long. The coordinates start at the trailing edge, move over the top to the leading edge and then alone the bottom back to the trailing edge. I wanted to do this because I have an airfoil that I made up that flies good. Now I can scale it with any wing plotting program. Mike RCSE-List facilities provided by Model Airplane News.
