Overview
MAD CB2 57x19 inch carbon fiber propeller (FLUXER series) designed for efficient, low-vibration flight. CB2 is an upgraded ultralight CF prop concepted as “Light as O2” (Carbon + O2). It is described as a high-quality, efficient carbon fiber propeller for endurance flight, with prop weight reduced by 20%–30% and flight time extended. Thrust is described as increased by 3%–7% and efficiency increased by 2%–6%. Each propeller is balanced 3 times during production for very low vibration.
