The LS-1 Standard Class design resulted from the collaboration of Wolf Lemke and Walter Schneider after they had worked together on the ground breaking Akaflieg Darmstadt D-36 project. Production models made their debut at the 1968 German Nationals, where they took first and second place. Helmut Reichmann won the Standard Class at the 1970 world Championship at Marfa, Texas in a LS-1. The LS-1 was produced in several sub-models, including the –1C with all moving tail, the –1D with water ballast, and the –1F with redesigned rudder and conventional tailplane. ATC.

The LS-3 was a 15 meter racing class sailplane with full-span flaperons instead of the more usual flap/aileron combination. The flaperons are coupled with dive brakes to reduce approach and landing speeds. The LS-3a version has separate flaps and ailerons. All –3 series use a fuselage similar to that developed for the Standard Class LS-1f, which features a front-hinged canopy and a fixed stabilizer on a T-tail. The LS-3-17 version was offered with a 17 m. wing with no change in gross weight. ATC

The Standard Class successor to the LS-1, the LS-4 first flew in 1980. It features a new airfoil (Wortmann mod.) on its double-tapered wing, larger upper-surface double segment Schempp-Hirth type airbrakes and a variety of rigging improvements. The fuselage is derived from that of the LS-3a. The improved LS-4a has an increased gross weight and ballast capacity and strengtened landing gear. LS-4’s took the first 6 places (and 21 out of the first 25) in the Standard Class at the 1983 World Championships at Hobbs, NM.
