It has a double-trapezoid, tapered and double polyhedral bended high aspect wing. It also has a built-in washout for tip-stall resistant flight characteristics, and lower drag. It features the SD7080-modified airfoil specially modified for this sailplane. The Sky 2M wing also could be built as polyhedral wing if desired by the builder.
