This and the large contribution of Wolf Lemke, who performed the aerodynamic and structural calculations, led to Rolladen-Schneider bestowing the type designation LS11 upon the Akafliegers' project.

The goal of the project is to design and build a thoroughly capable school glider with top performance for cross-country training, record flying and competition.

The wings, almost entirely made of Carbon fibre Reinforced Plastic, were manufactured at the Rolladen-Schneider factory in Egelsbach in mid-2001, while the span extensions were built in the moulds developed by the Darmstadt group for the D41.

The cockpit, manufactured from carbon and aramid reinforced plastic, was designed to accommodate pilots up to two meters tall.

The hinge is a carbon reinforced element able to withstand wind speeds up to 75 km/h when open and was designed to sever the tubing and wiring looms from the instrument panels upon emergency release in flight.

The wings are connected by two main pins inserted into the tongue-and-fork spar ends, as in the LS6 and subsequent LS types.

Wolf Lemke and Siegfried Piontowski decided to depart from the typical LS system in which ailerons and flaps act as flaperons, using a mixed schedule as featured in the Schleicher ASW 27.

Multiblade airbrakes extend from the upper surfaces of the wings to give ample glidepath modulation.
