S27 - Foil Mast

The redesigned Naish alloy mast introduces an upgraded 6061 aircraft-grade aluminum extrusion, enhancing strength by nearly 25% with minimal additional weight. This improvement is achieved through a new section design that strategically increases wall thickness in critical buckling zones while maintaining the sleek exterior dimensions and aerodynamic profile of the S26 mast.

Key enhancements include a newly integrated board mount with bonded and screwed connections (using 2x M8 screws and sex bolts), ensuring a secure and stable attachment. The mast connects directly to the fuselage via 2 M8 screws, utilizing a molded fuselage connector that acts as a protective barrier against corrosion.

Please note, this mast is exclusively compatible with newer fuselage models and is not suitable for use with S26 and older fuselages.
