This is the APC 9x4.5 Thin Electric Propeller, a high-quality propeller designed for electric-powered applications. Manufactured using the pultrusion process, APC propellers feature an impressive fiber (60%) to resin (nylon binder) density, providing exceptional strength and stiffness compared to glass-filled nylon propellers.
The additional stiffness of these propellers is instrumental in controlling vibration resonance response, ensuring a smooth and balanced flight experience. Additionally, the higher strength allows for the use of thinner cross-sections, resulting in reduced weight and improved aerodynamic efficiency.
Key Features:
• Incorporates a computer-optimized design, resulting in a thinner profile and enhanced traction while minimizing noise levels
• Constructed with lightweight molded nylon material, reducing rotating mass for increased output and extended propeller lifespan
• Features reinforcing fibers that maintain a consistent pitch at any RPM, ensuring reliable and precise performance
