Our Aero SLS masts in combination with AL 3BS fuselages are amongst the strongest setups you can ride, while keeping the weight low. With incredibly high structural strength in both torsion and bending loads, the SLS masts offer incredibly direct steering response even when used with wings of highest spans. The sleek and weight optimized AL 3BS Fuseages are the perfect match for our SLS masts and combine lowest drag with highest level of rigidity for an exceptional riding experience.
