Daimler L15

The Daimler L15, later also called the Daimler-Klemm L15, was an early two-seat, low-powered light aircraft intended to popularise flying. Hanns Klemm designed it in 1919 after moving to the aircraft branch of Daimler, as a high cantilever wing machine with a 6 kW Indian motorcycle engine and unusual rotating wingtips in place of ailerons. In 1922 it was rebuilt as a glider for the Rhon contests, since Germany was forbidden to build aeroplanes, and in 1923 it was powered again with a Harley-Davidson motorcycle engine. It later flew on floats and reached a height of 2,150 metres. Its success pointed Klemm toward the L20 and his own light aircraft company. It was shown in the Deutsches Museum as the first light aircraft but was destroyed in the Second World War.
