The Duotone Aero AL 3BS is a high-rigidity aluminium fuselage designed to offer optimum control, increased stability and direct energy transmission between the front wing and the horizontal stabiliser. Its 3BS (triple beam structure) reinforces its longitudinal and torsional strength, guaranteeing precise handling even at high speeds or during the most committed stalls. Its geometry has been designed to improve carving fluidity, stabilise pumping phases and provide a clear reading of the foil underfoot. The assembly is simple, reliable and perfectly adjusted, allowing you to test different wing/stab combinations while maintaining a solid, consistent base. Thanks to its balance between rigidity, control and versatility, the Aero AL 3BS allows you to immediately feel the differences in behaviour between the wings and to understand what best suits your sailing style. An ideal fuselage for a test before finalising its choice of equipment.
