August Euler, Frankfurt a.M. In 1908 Euler secured Voisin rights for Germany. In 1910 he took out a patent for a design of his own. In the summer of 1911 he built a succe ful monoplane, in the autumn of the same year a triplane. Existing models are as follows:— | 1912. Triplane. | 1912. Monoplane. | Military biplane. | | Length | feet (m.) | 23 (7) | | Span | feet (m.) | 23 (7) | | Area | sq. feet (m².) |... | | Weight | total lbs. (kgs.) |... | no data | no data | | useful lbs.
