Rolladen-Schneider LS1 - Variants

Variants

• LS1-0 V-1 - prototype had an internal load bearing tubular steel scaffold (as in present-day Schempp-Hirth sailplanes). This structure was substituted by full GRP construction in production versions.
• LS1-0 - angle of incidence was increased and improvements to the control system. (23 built of LS1-0. LS1-a, and LS1-b together)
• LS1-a - trailing edge air brakes of the prototype were dropped in favour of conventional Schempp-Hirth air brakes (chinge incorporated on all further variants) (23 built of LS1-0. LS1-a, and LS1-b together)
• LS1-b - (23 built of LS1-0. LS1-a, and LS1-b together)
• LS1-c - (198 built of LS1-c and LS1-d together)
• LS1-d - was the first to have water ballast, following a class rule change. (198 built of LS1-c and LS1-d together)
• LS1-e - version was built privately by a Rolladen-Schneider employee under the direction of Wolf Lemke. Differs from the LS1-c only in the use of an LS2 type tailplane (2 built)
• LS1-ef - tailplane of the LS1-f and the same fuselage as former versions (1 built)
• LS1-f - introduced the one-piece canopy, conventional tailplane, redesigned rudder and structural changes that allowed more water ballast and higher flight mass. It also has a reduced wing incidence relative to the fuselage, resulting in noticeably better high speed performance than the earlier LS1 variants. (240 built)
