Wing riggers are not interchangeable across our shells. The Winged Aero and the Maas 24 share the same basic wing, but there are some differences in the angles. Likewise the Flyweight and Maas 27 share a rigger, but with differences in the angles. The Maas Double has itβs own wing. The Classic Aero can only take a wing with the adapter kit, the internal structure of the Classic is NOT designed for the stress of the wing without reinforcement.
