The Rolladen-Schneider LS8 is a Standard and 18 metre class single-seat glider developed by Rolladen-Schneider and in series production since 1995. Currently it is manufactured by DG Flugzeugbau.

By the mid-to–late eighties the LS4 had lost its leading position in the Standard Class to new arrivals, in particular the excellent Discus from Schempp-Hirth. The LS7, in spite of its advanced design, did not recapture the lead and, with flagging sales, Rolladen-Schneider went back to the drawing board.

Designer Wolf Lemke was skeptical of the usefulness of developing a new airfoil. There was no guarantee that the large effort and investment required would bring any palpable gains, as the LS7, ASW 24 and DG-600 had clearly shown. The tools available at the time were simply not up to the task of reliably predicting the performance in everyday conditions of the newer laminar profiles then emerging from the research labs.

The 15 meter Class LS6 was however achieving surprisingly good results flying with locked flaps in the non-FAI sanctioned Sports Class in the United States. Following this lead, Rolladen-Schneider modified an LS6-c by removing the flap handle, resetting the wing at a slightly higher angle of incidence and adding winglets. This experimental prototype outperformed state-of-the-art standard class sailplanes both in side-by-side flight tests and in contests including the German Championships at Neustadt-Glewe.
