The AG5x are the wing airfoils: - Basically lower-camber versions of the AG40-43 which were aimed at F3J and TD. - Longer laminar runs at the large Re ~ 600K, typical of an F3B speed run. - Intended hingeline is at 75% chord. - Trim flap range is -1 deg (speed) to +4 deg (float). The HT3x are the tail surfaces: - Replacements for the usual HT1x tail surface airfoils. - More laminar flow in an F3B speed run. [4] Selig airfoils used on the Opus 100 inch span (standard class) RC sailplane (designed by Selig around ~1991). These airfoils started life as proprietary sections, and on 12/6/02 they were made public. The Opus was available from http://www.nesail.com (Northeast Sailplane Products): 021206-opus.pdf [5] Selig airfoils used on the carbon Blackhawk 113.5-inch span (open class) RC sailplane (designed by Selig around ~1991). The Blackhawk is no longer produced. These airfoils started life as proprietary sections, and on 12/6/02 they were made public. Thanks go to the original backers of the Blackhawk project: Ray Olsen, Don Scegiel, and Doug Diesen (Scottsdale, AZ).

I don't know; however, I am labeling it as such based on communications with Prof Fred Culick at Caltech. He has done considerable research on the topic and believes that this airfoil is very close to the 1903 Wright Flyer airfoil. Keep in mind this aircraft had deformable fabric-covered wrapping wings, so as hard as one might try it is only possible to approximate the 1903 Wright Flyer wing section with a single airfoil.
