This is the APC 5.25x6.25 Speed 400 Electric Propeller, a high-performance propeller designed to deliver exceptional speed and efficiency. Crafted using an advanced pultrusion process, APC propellers offer a superior fiber-to-resin density, with 60% fiber content and a nylon binder. This manufacturing technique results in significantly increased strength and stiffness compared to propellers made from glass-filled nylon. The additional stiffness effectively controls vibration resonance response, while the heightened strength enables the use of thinner cross-sections, benefiting weight reduction and optimizing aerodynamic efficiency.
Key Features:
• Computer-optimized design ensures a sleeker profile, providing improved performance with reduced noise levels
• Lightweight molded nylon construction minimizes rotating mass, enhancing power output and extending overall lifespan
• Reinforcing fibers maintain a consistent pitch at any RPM, ensuring reliable and precise performance
