[2] After Fokker's visit to the Wasserkuppe during the 1921 contest, he set about designing and building a two-seat biplane glider to fly at the 1922 competition.
A strut- and wire-braced biplane with tail surfaces supported on an open framework, Fokker's glider had a fabric-covered two-seat tandem cockpit nacelle sitting on the lower wing.
[2] Fokker also built a similar single-seat biplane glider which was not flown regularly.
[2] Fokker test flew the two-seater solo after it was assembled at the Wasserkuppe, revealing poor directional stability.
Rudders with greater area were fitted to rectify this, which allowed competition flying and passenger flights to commence; Fokker soon soared the biplane two-seater for thirteen minutes with a passenger aboard.
