The original:

The Arcus is a two-seat high-performance glider made by Schempp-Hirth Flugzeugbau GmbH with a wingspan of 20 meters and flaps, whose maiden flight took place on April 7, 2009.

The maiden flight of the variant designated as Arcus E with electric propulsion followed on September 18, 2010.

The Arcus is being built as a pure glider, with an auxiliary engine for flying through longer areas without thermals to avoid an outlanding, as a selflaunching version and as a selflaunching version with an electric motor, the latter version in cooperation with Lange Flugzeugbau.

According to the manufacturer, the glide ratio is about 50. The Arcus M received its 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. Subsequently, the Arcus was able to win further titles, including a development engineer, Andreas Lutz together with Wolfgang Janowitsch, who became two-time European champion (2013/2015) with the Arcus M.

The model:

The model excels for its size with unusually uncritical flight and stall behavior. Typical for its size, the Arcus wants to be launched and flown briskly. However, a powerful hand launch is possible without problems.

Thermal characteristics and maneuverability are exceptionally good for its size. The flight pattern spoils every model flyer's heart. It is a unique model, which looks for its equals in this size, but does not find!

Christian Walliser is the constructor of the model. For the construction of the Arcus some building experience is necessary.

The pack size is only 1.22 m.
