APC Props
AP-09037SF
This is the APC 9x3.7 Slow Flyer "SF3D" Propeller, a top-notch propeller designed for slow-flying applications. Crafted with precision using the pultrusion process, APC propellers exhibit an impressive fiber (60%) to resin (nylon binder) density, surpassing the strength and stiffness of glass-filled nylon propellers.
The additional stiffness of these propellers plays a crucial role in controlling vibration resonance response, ensuring a smooth and balanced flight experience. Moreover, 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
