The Rolladen-Schneider LS5 was an Open Class single seat sailplane designed by Rolladen-Schneider of which only a single unit was built.
History
The LS5 was announced in 1980 as Rolladen-Schneider’s entry into the exclusive Open Class. The economic viability of the design was compromised, however, with the arrival in 1981 of the Schempp-Hirth Nimbus-3 and Alexander Schleicher ASW 22, both of which outclassed the theoretical performance of the yet-to-fly LS5. Although the moulds had already been completed, Rolladen-Schneider decided not to pursue further development. Klaus Mies from Kaiserslautern used these moulds to produce one glider of the type. This home-built prototype made its maiden flight in 1988, receiving the registration number D-7742. It is presently based at Marpingen in Germany.
