Check the listing for details. APC 11x7E-3 Three Blade Propeller [APCLP311070E]. Color: Grey, Condition: New. Listed at 11.99 USD. This is the APC 11x7E-3 Three Blade 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 Compatible with the E-flite Turbo Timber 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: 11in (279.4mm) Pitch: 7in (177.8mm) Hub Diameter: 0.8in (20.32mm) Hub Thickness: 0.42in (10.668mm) Shaft Diameter: 0.31in (8mm) Weight: 1.09oz (30.9g) Rotation: CCW (Standard/Tractor) About Us | View Store
