This is a nice, premium product, Made in USA. Tested in a real engineering wind tunnel, Cutting Edge Power's thick UV resistant 5 blades and hub are designed for any generator with a 1/8" shaft. The hub is press fit and locks to the shaft with 5 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.
- Infinite Air
Good in low winds
Adapted easily to fit my Infinite Air. I use it when out hiking for >7 days. Works in 9kph winds, better than 13-15kph minimum of the original. Different sound, just swishing not wining. A little heavier at 259g. Swapped the crossheads for hex key screws. Perfect would be a tool-less hub/****** for quicker setup. Worth having.
Great design, using for a mini wind turbine. Will update with pics when finished.
Just as explained.
Perfect nothing wrong, just as explained.
