Wing Ship Technology Corporation Prototype
 
 WingshipTech-Proto
 
Wing Ship Technology Corporation prototype is powered by a turboprop and can carry 50 passengers. It has a catamaran-style hull and a reverse delta wing. Its cruising speed, 180kph (110mph), makes it faster than a jetfoil, its principal rival. And the production version will have a range of 1,000km.
 
 
 
Wacyk-Tyrala WT-1
 
Stanisław Wacyk and Tadeuz Tyrala designed the high performance sports WT-1 aircraft during 1930 and they largely financed the construction of its fuselage at the Aviation Circle of the Industrial School at Kraków and wings in the workshops of the Kraków Air Regiment. It was completed in the summer of 1931.
 
The aircraft was an aerodynamically clean cantilever wing monoplane. Its high-mounted, one piece wing was built around two spars, with a plywood covered leading edge and fabric covering. Narrow chord ailerons occupied the whole of the trailing edges.
 
The WT-1's borrowed 67–73 kW (90–98 hp) de Havilland Gipsy I four cylinder upright inline engine was mounted largely exposed, though with a fairing behind it. The ply-covered fuselage had rounded decking; the fuel tank was in the forward fuselage and its two seat, side-by-side cockpit was behind the wing trailing edge. The fuselage tapered rearwards, with the tailplane mounted on top. A tall triangular fin carried a rounded rudder, which reached down to the keel. Its fixed landing gear was conventional, though details are not known.
 
An initial first flight was abandoned due to a fuel supply problem. The system was modified and a new fuel pump fitted, after which Stanisław Szubka piloted its first flight, finding the WT-1 hard to fly because of a misplaced centre of gravity (c.g.), and damaging it on landing. After accident repair and c.g. adjustment the WT-1 was flown by Jerzy Bajan. The take-off run was short and performance high, but Bajan found its handling dangerous. At this point the loaned Gipsy engine had to be returned to the Kraków Air Regiment and the development of the WT-1 was abandoned.

Howard Wright Avis
 
 Wright-Avis-01
 
Howard Wright designed and built helicopters, ornithopter, biplanes, and series of monoplanes, including five Avis.
 
Wright-Avis-02
 
Named “The Golden Plover” – and fitted with an Anzani three-cylinder delivering 25 to 30 hp – this wing-warping monoplane was delivered to the Scottish Aviation Syndicate in 1910.
 
 
 
Vans RV-1
 
One Stits SA-3A Playboy builders eventually sold his project to a young aviator who rebuilt the wing, getting rid of the struts and converting it from a fabric covered wooden frame to an aluminum wing in 1965 (and calling it an RV-1). The rebuilder was Dick VanGrunsven and his first airplane has been rebuilt and will be donated to the EAA museum this summer.
 
VanGrunsven was further inspired to build an airplane of his own design — the RV-3.
