Product Description
Designed and made to pick up the wind power as much as possible. The efficiency is graded as 0.48 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.

Seller claims that the diameter is 13.1 ft (4m), after I received the blades I measured it and it is only 12.5 ft (381 cm). Seller still claims it is 13.1 ft (4m)! Sellers ad gives wrong shipping weight (the seller knows that but has not changed that) and after I already had paid the correct total sum according to his shipping calculator, the seller demanded $118 more, otherwise he would not ship the hub which is included in the price. This same seller is using several different seller-ID:s. I would check everything he claims very carefully.
