This is the APC 5.25x4.75 Speed 400 Electric Propeller, a high-performance propeller designed to optimize speed and efficiency. Crafted using a state-of-the-art pultrusion process, APC propellers feature a higher fiber-to-resin density, with 60% fiber content and a nylon binder. This exceptional manufacturing technique results in significantly heightened strength and stiffness when compared to propellers made from glass-filled nylon. The increased stiffness effectively controls vibration resonance response, while the augmented strength allows for the use of thinner cross-sections, benefiting both weight reduction and aerodynamic efficiency.
Key Features:
• Computer-optimized design ensures a sleeker profile, delivering enhanced performance and reduced noise levels
• Lightweight molded nylon construction minimizes rotating mass, resulting in heightened power output and extended lifespan
• Reinforcing fibers maintain a consistent pitch at any RPM, guaranteeing reliable and precise performance
