Has anyone drawn a cad version of the Starduster Too airfoil, (reportedly M6). I digitized the rib drawings into CAD from an old set of paper drawings. I know they are accurate enough to build a one off airplane but for cad there is a lot of variation from rib to rib in areas that should be identical. I could average the variations but this is the time to get it right. I downloaded the M6 coordinates and overlaid the M6 on the Starduster ribs, even more variation with that! From the M6 plot, among other things, the M6 rib is thicker aft of ~30% on top, and towards the trailing edge the M6 has a considerable upsweep. I thought the coordinate file I downloaded might be wrong so I investigated it from different sources and got similar or worse results. Maybe, as has been done with many other designs, Lou looked at the M6 and modified it to his liking?
