Horten H VI V2

From 1933 to 1990, Reimar Horten, assisted by his brother, Walter, designed and built a series of swept-wing aircraft without fuselages or tails and they did not use any other surfaces for control or stability that did not also contribute lift to the wing. Horten began to consider his sixth major design when construction began on the first Horten IV in December 1940. The H IV became the most successful all-wing aircraft that Horten developed and it encouraged him to explore further the potential of high aspect ratio (AR) wing design. He completed the first Horten VI four years later but this sailplane was experimental and not intended for series production so Reimar designated it 'vee-number-one' to indicate its prototype status.Horten built two examples in the summer of 1944. The Horten VI used a complex flight control system that was similar to the Horten IV and Horten equipped it with a semi-prone position for the pilot. Flight tests uncovered a tendency for the wingtips to flutter at about 128 km/h (80 mph).
