It seems tougher than I expected. I was waiting for the blades to fail. About 12 weeks of pretty harsh weather had very little effect on the blades.
So I gave up waiting for a failure and just slid out the blade & hub assembly and removed 2" from each blade. More effort was spent on better balancing this time.
As expected, it takes a little more wind to start turning.
Once it is turning, it turns MUCH faster than the 25~30% I expected it would. Possibly double the RPMs at the same wind speed.
Now I expect the LEDs to light up about the same time my wind gauge will register (6mph).
The 12" blades may be better set at 5 or 6 degrees?
Big Silly Fun!
