The glider is reported to have pleasant handling [1] and to be easy to assemble, with automatic control hookups.
With an empty weight of about 215 kg, it is the lightest of the current standard class gliders and it's known for its excellent climbing and thermalling characteristics.
Since the mid-eighties, the best glider in the standard class was undoubtedly the German standard Discus, whose excellent performance was attributed to its unusual triple trapeze wing shape.
So it was the logical step to adopt a similar idea for use as the outline of the new construction: the elliptical contour of the wing leading edge.
Despite enormous difficulties in obtaining advanced materials (carbon fabric, kevlar) which meant that the glider had to be built with glass-epoxy laminates (already a relatively old technology at the time) the manufacturer managed to create a glider with an unladen weight of just over 200 kg.
