Sigma 11

The cross country SIGMA 11 is up amongst the highest performing C class wings, with exceptional handling precision in flight and a high level of pitching stability. Its outstanding performance can be called upon, even in demanding conditions.

Latest technologies like internally sewn miniribs and an effective pitch control arrangement with 2-liner feel finish off this product. Improved SIGMA 11 internal load distribution design makes for simpler packing because C-wires are no longer required. The market launch will take place in time for the next XC season in spring 2021.
