This is the APC 7x4 Thin Electric Propeller, a high-performance propeller designed for exceptional efficiency. Manufactured using an advanced pultrusion process, APC propellers feature a higher fiber-to-resin density, with 60% fiber content and a nylon binder. This innovative manufacturing technique provides substantially higher strength and stiffness compared to propellers made of glass-filled nylon. The additional stiffness effectively controls vibration resonance response, while the enhanced strength allows for the use of thinner cross-sections, resulting in improved weight reduction and optimal aerodynamic efficiency.
Key Features:
• Computer-optimized design ensures a thinner profile, delivering improved performance with reduced noise levels and enhanced
biting capability
• Lightweight molded nylon construction minimizes rotating mass, resulting in higher output and extended lifespan
• Reinforcing fibers help maintain a constant pitch at any RPM, ensuring reliable and precise performance
