This is a APC 4.1x4.1 Speed 400 Electric Propeller, a high-performance propeller designed for optimal functionality. These propellers are meticulously crafted using an advanced pultrusion process, resulting in a remarkable fiber-to-resin density of 60%. This unique manufacturing technique imparts superior strength and rigidity compared to traditional glass-filled nylon propellers. By harnessing this additional stiffness, the propeller effectively mitigates vibration resonance, enhancing control and stability. Furthermore, the increased strength allows for thinner cross-sections, resulting in reduced weight and improved aerodynamic efficiency.
Key Features:
• Computer-optimized design for a sleeker profile and enhanced performance with reduced noise levels.
• Lightweight construction using molded nylon, reducing rotational mass for greater power output and extended lifespan.
• Incorporation of reinforcing fibers ensures consistent pitch at any RPM, maintaining optimal performance.
