Our high-end mast & fuselage set comes with Our Duotone Mast-Fuselage Set Aero Slim D/LAB/AL 3BS mast featuring a slimmer profile with a stiffer layup made with a special blend of high modulus Carbon fibres for ultimate performance, speed and direct response. Due to its thinner structure these masts are only recommended for wings up to 100cm span. Combined with AL 3BS fuselage this set is for everyone looking for full compatibility of the previous Fanatic and new Duotone range of SLS wings.
