The RRG Fafnir 2 São Paulo, named after the legendary dragon and the Brazilian city which partially financed it, was a single seat German high performance glider designed by Alexander Lippisch.
Apart from being a wood and fabric aircraft with a strongly tapered cantilever gull wing, it had little in common with the Fafnir of 1930, though lessons had been learned from that design.
[1] The Fafnir 2's fuselage was carefully streamlined with a ply skin and had an underlying oval cross section, but the requirement to produce a camber form which blended into the wing made the detailed shaping complex and time-consuming to build.
When first built its cockpit, ahead of the wing leading edge, had a stepped, multi-framed glazed canopy though by 1937 this had been reworked to blend smoothly into the forward fuselage line.
[1][2] It was the best glider of those at the 1934 Rhön, with a measured glide ratio of 26:1, a good figure for the time but not sufficiently outstanding to invite imitations, given the complexity and expense of the wing/fuselage blending.
