This is the APC 9x4 Sport Propeller, a high-performance propeller designed for sport applications. Manufactured using the pultrusion process, APC propellers possess a remarkable fiber (60%) to resin (nylon binder) density, delivering superior strength and stiffness compared to glass-filled nylon propellers.
The additional stiffness of these propellers plays a pivotal role in controlling vibration resonance response, ensuring a smooth and balanced flight experience. Moreover, the higher strength enables 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 bite 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
