This is the APC 9x6 Slow Flyer 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 Specifications: Propeller Diameter: 9in (228.6mm) Pitch: 6in (152.4mm) Hub Diameter: 0.5in (12.7mm) Hub Thickness: 0.3in (7.62mm) Shaft Diameter: 0.25in (6.35mm) Weight: 0.32oz (9.07g) Rotation: CCW (Standard/Tractor)
