ADVANCE Sigma 10 — An Unstretched Aspect Ratio and a Reworked Structure

A good B pilot with about two seasons on their wing could make the Sigma 10 their first C. It stays comfortable in active air and the speed bar is easy to use, which suits pilots who want to go far on strong thermal days. The trade-off is weak lift below 0.5 m/s, where a wing like the Cayenne 5 floats slightly better.
