Average Reviews:
(More customer reviews)I set up the blades and used them for over 6 months. First, the hub comes with a tapered hole, which if you have a lathe this is not a problem.
Second they are hollow and must be protected against moisture entering the cavity of each blade. Water proof (Not just 'water resistant') coating must be applied. Mine was destroyed when heavy rains got into one blade and unbalanced the whole wind generator. Vibration and high speed broke shaft. The blades were found in the field behind house, all broken from 50 foot tower! Fill with foam or coat with mentioned water proofing.
Carefully weigh each blade for exact same weight.
Tips are about 97.625 inches from each end. Get them exactly 120 degrees apart
These blades are made for a high wind area.

Designed and made to pick up the wind power as much as possible. The coefficiency is 0.49 in converting wind power to the mechanical power, which is at the very top end (the highest is 0.5). The exact same blades are widely used in commercial wind generators. The performance of the blades is much better than home brewed ones.
