The SIGMA 11 is, once more, one of the best performing wings of the C Class. The cross country Sportster has outstanding pitch stability as well as very precise handling. State of the art technologies such as 3X3D shaping at the leading edge and an efficient Pitch Control System with 2-liner feeling round off this product. ADVANCE quality lightbuild structure produces the SIGMA 11 from 4 kg.


A completely redeveloped profile gives the SIGMA 11 significant pitch stability. This results in not just a marked increase in performance in turbulence, but a much higher level of flying comfort on long flights. 3X3D shaping, reduced line surface area and a swept element to the wing planform are all further performance-enhancing features of this high-end XC wing.


The SIGMA 11 delights with its comfortably direct handling, immediately conveying the feeling of this wing’s sportiness to the pilot. Perfectly refined wing curvature and well-proven brake line geometry allows the XC Sportster to answer its smallest control input directly and precisely. This playful handling guarantees the best flying fun.


Weight-optimised internal structure means that a SIGMA 11 is available weighing only 4 kg, even though the outer wing surfaces are constructed of 38gm/32gm fabric. Ideal internal wing stress distribution design means that the wing does not have C-Wires on its upper surface, making it even more light and compact. Modified C level supports also improve extreme flight characteristics and raises the passive safety level.
