I finally won a set of blades and hub. There are 6 blades made from a type of fiber filled plastic, designed to spin up to 2000 rpms or more.
The diameter is around 5ft and the hub will allow me to try 2, 3, or 6 blades.
The pics show where I currently am. I just made an adapter so the hub would fit the shaft of my motor.
I still need to buy the tower pipe and do some testing to make the tail fin with the correct mass to furl at the wind speed I decide on. The furling is more for inverter and generator protection than for the blades. All the designs I've seen using these blade don't use any furling. They are supposedly pretty durable blades.
After some testing I will decide which grid tie inverter to go with. So far I have my eye on a nice 400watt one with a low startup voltage. I have an arduino that I plan to attempt to use for load control eventually.
