This is a nice, premium product, Made in USA. Tested in a real engineering wind tunnel, Cutting Edge Power's thick UV resistant 3 blades and hub are designed for any generator with a 1/8" shaft.  The hub is press fit and locks to the shaft with 3 stainless steel set screws (included).

Compatible with Cutting Edge Power Mini Wind Turbine.

  • 18" swept diameter
  • Specially designed brass threads are pre-assembled and heat set into the blades to eliminate vibration. (included)
  • Black stainless steel machine screws provide a long-lasting outdoor finish.  (included) These are not zinc or carbon steel screws, they are stainless.

Aerodynamic grooves on the blades create a thin turbulent boundary layer on the surface, which allows the blade to flow smoothly through the wind, similar to golf ball dimples.
