Re: 100W Turbine plans - blades

The reason they fail and drop is because they throw everything out of balance; as soon as a fatigue crack forms the blade deforms. The blades will rock back and forth, furthering the crack until the blade falls off. I've watched it happen several times by using too light of material and the heavier blades did the same.
