Light winds today but still I had a blade come apart.
The fiberglass in one blade had a major flaw. There was a large void in the fiberglass mesh that did not have any resin in it just above the root.
The blade tore out at that point and the massive imbalance crashed the generator.
It was not a generator design flaw on my part but just a simple blade manufacturing defect.
After falling 20 feet and landing on the blades the other two broke of at the root and bent the hub and shaft.
However to pat myself on the back for design robustness the whole frame and motor/gear box are still in solid usable shape! Only one slight ripple in the tail frame behind the pivot point.
Not bad for 150 pounds of metal crashing down from 20 feet while still spinning!
It landed right as you see it, fully salvageable and reusable!
I am trying to contact the company I bought the blades from to see if there is any warranty coverage for showing proof of a manufacturing defect.
