388:- 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)
202:
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

Variants up to the LS1-d had an all-flying tail with oversensitive handling characteristics at high speeds. A conventional stabiliser and elevator were adopted for later variants. Although fractionally less efficient, this is much safer and more pleasant to

The undercarriage was initially fixed, as required by the standard class rules of the time. The wheel was sprung and had its own wheel housing, separate from the internal fuselage space. The wheel brake was coupled to the air brake

of almost 20%, made it possible to build a light and economical spar. This was important because in the late sixties glass fibre was the only affordable reinforcement material - carbon was still too expensive.
348:- trailing edge air brakes of the prototype were dropped in favour of conventional Schempp-Hirth air brakes (change incorporated on all further variants) (23 built of LS1-0. LS1-a, and LS1-b together)

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.

fuselage shell was produced in female moulds, in an innovative method developed by Wolf Lemke. The LS1 V-1 prototype was the pattern or âplugâ for the serial production moulds.

The designers desired to demonstrate that high performance and pleasant flight characteristics could coexist in a standard class sailplane built with the then still-unexplored

The materials used were glass fibre, Conticell foam, polystyrene, plywood for the spar webs and hardwood in reinforcements. Wood was phased out in the LS1-f version.
