Comment:
After the RS-1, Ross was commissioned by the Soaring Society of America to design and build the RS-3 ムIbisメ for promotion purposes. The R-2 was quite similar to the RS-1 but the gull wing had a 48 ft. span and an all-moving tail was used. It made the first wave flight I the U.S. on Oct. 25, 1938, at White Mountain, New Hampshire. Ross later altered the design to remove the gull wing, change the airfoil and simplify construction for homebuilders, designating it the R-3. Hicks bought a set of plans and built a modified R-3 (RH-3) by extending the wing, using laminar airfoil and flaps, first flying in 1963. The Vintage Sailplane Association has plans.
