APC 9x3.7 Slow Flyer "SF3D" Propeller

This is the APC 9x3.7 Slow Flyer "SF3D" Propeller. APC propellers are manufactured using a pultrusion process which allows for a higher fiber (60%) to resin (nylon binder) density. This provides substantially higher strength and stiffness than glass-filled nylon. The additional stiffness is beneficial to control vibration resonance response. The higher strength allows the use of thinner cross-sections, beneficial to weight and aerodynamic efficiency.

Features:

• Computer-optimized design gives these props a thinner profile and more "bite" with less noise
• Lightweight molded nylon construction reduces rotating mass for higher output and longer life
• Reinforcing fibers help maintain true, constant pitch at any RPM
