Duotone Fuselage AL 3BS – Optimized Aluminum Efficiency

Duotone Fuselage AL 3BS represents the evolution of our 3BS fuselage system. Building on the success of the 60 cm version, it is now available in 66 cm and 74 cm, delivering reduced hydrodynamic drag and increased structural strength.

Reduced Cross Section

• Lower drag profile – Reduced fuselage resistance.
• Integrated rear recess – Improved stabilizer flow transition.
• Weight-saving cut-outs – Optimized structure without compromising strength.

Increased Strength

The aluminum construction increases structural resistance with only a minimal weight increase of approximately 2.5% compared to previous carbon versions.

Available Lengths

• 66 cm – Balanced stability and maneuverability.
• 74 cm – Enhanced stability and directional control.

AL 3BS fuselages require fresh water rinsing after use to maintain long-term durability.
