The Rolladen-Schneider LS1 is a Standard Class single-seat glider manufactured in Germany by Rolladen-Schneider from 1968 to 1977.

Development

The LS-1 Standard Class design was the first aircraft type arising from the partnership between Wolf Lemke and Walter Schneider, who had already worked together as students on the ground breaking Akaflieg Darmstadt D-36. Here, and in subsequent Lemke-Schneider (LS) designs, Wolf Lemke concentrated on the aerodynamics while Walter Schneider contributed mostly to the structural and production issues. The LS1 made its debut at the 1968 German National Championships, taking first and second place with the designers themselves at the controls. The success of this design increased in the subsequent years until, in 1975, it was the most flown glider in the German Nationals. The LS1-c took first place in the 1970 World Championships at Marfa, Texas. Jan Rothhardt also won the World Gliding Competition Championships 2015 in the Club Class. Furthermore Christoph Nacke became Junior World Gliding Champion in the Club Class in 2005. The manufacture of the LS1 was discontinued after the IGC introduced the new unrestricted 15 metre-class in the spring 1977, as the manufacturer needed all its resources to increase production of the LS3. A total of 464 LS1 were built. Among Rolladen-Schneider’s Standard class gliders it was succeeded by the LS2 (one only) and LS4.
