The Arcus is a two-seat high-performance glider from Schempp-Hirth Flugzeugbau GmbH with a wingspan of 20 meters and flaps, whose maiden flight took place on April 7, 2009; the first flight of the electrically powered variant known as the Arcus E followed on September 18, 2010.
The Arcus is built as a pure glider ( Arcus S or just Arcus ), with an auxiliary power unit for flying through longer areas without thermals in order to avoid an outland landing (colloquially "Turbo", therefore Arcus T , with a Solo 2350 engine ), as a self-launching version ( Arcus M , with a Solo 2625 engine) and as a self-launching device with an electric motor ( Arcus E ), the latter version in cooperation with Lange Flugzeugbau .
According to the manufacturer, the glide ratio is around 50. The Arcus M received type certification on June 20, 2013, and Christof Geissler and Christoph Wannenmacher, development engineers at Schempp-Hirth, had already become German champions in Aalen in 2009 . The Arcus was then able to fly further titles, including a development engineer, Andreas Lutz, together with Wolfgang Janowitsch, two-time European champion (2013/2015) with the Arcus M.
