Our Freedom I and Freedom II PMGs are designed with a keyed shaft and hub stabilizer as well as includes a self-tightening cam-lock washer to prevent the blade set from ever spinning on the shaft.

How easily do the blades turn? What about cogging? The Missouri Freedom Wind Turbines have a cut-in wind speed of 6 MPH and NO COGGING!

The Raptor G4 wind turbine blades are made from revolutionary carbon fiber composites (used by the aircraft industry) - The same material used in the F-22 Raptor fighter jet.

Designed for high speed, high efficiency, affordability and durability.

Our Raptor Generation 4 blades can last 75 years in the sun! Made to withstand extreme heat and sub-zero temps, our blades are designed for high speed, high efficiency, affordability and durability.

They are rated to withstand 125 mph winds and are designed to operate real PMG's (permanent magnet generators) at high speed in low winds to create the maximum power a PMG can put out. Our precision, aerodynamically tapered blades feature a 5.5 mph start up speed.

We've tested many blades on the market and have concluded that our Raptor Generation 4 blades are hands down the best for durability, performance, aesthetics, and overall value.

No slip rings to fail or replace. Simple and effective, the turbine uses a wire tension system which will last a lifetime. The single power transmission cord never twists because the wind never spins the turbine around in the same direction hundreds of times. Typically, the wind only comes from two directions. It has yet to be an issue with any one of the thousands of turbines we have distributed.
