Does anybody know if the Applied Aeronautics group at UIUC has ever tested a KF airfoil section as part of their low-speed airfoil program? They've tested a lot of airfoils specifically at the request of RC modeling groups.
Near the bottom of that page is the following text:
Our tests are supported in large part by a group of dedicated model makers / volunteers focused on a common interest in model aviation. If you are interested in helping and want to make a wind tunnel model for testing at UIUC, see the wind tunnel model construction notes for more information. For flapped models, brackets are added to the ends to secure the flap for specific settings. If you have in interest in a particular airfoil that you'd like to see tested, contact us.
