Overview
MAD CB2 PRO 27x8.8 is a carbon fiber propeller designed with a matte surface and 12K carbon cloth for reduced noise and higher strength. The model targets a common thrust range of 4 to 8.5 kg within a common speed range of 2800 to 3950 RPM.
Key Features
- Lightweight design to reduce propeller weight and moment of inertia for improved response and control flexibility
- 12K carbon cloth for excellent fatigue resistance and higher strength
- Matte surface to reduce friction with air and lower flight noise
- Optimized wing shape for improved thrust and efficiency (graphic indicates 5%)
- Low-noise design (graphic indicates 3%)
- Manufacturer notes ultra-light customization service is available (weights/strengths tailored to flight needs)
