This is the APC 9x4.5 Thin Electric 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: 4.5in (114.3mm)
  • Hub Diameter: 0.8in (20.32mm)
  • Hub Thickness: 0.38in (9.652mm)
  • Shaft Diameter: 0.25in (6.35mm)
  • Weight: 0.63oz (17.86g)
  • Rotation: CCW (Standard/Tractor)

Very durable!

I bought several propellers but am still on my first. It has survived several high speed crashes with no visible damage.
