Took about a month to build. Using a servo 180v 3000rpm motor. rated at 1.2 kw. Got a set of those 505 by 5 blades on it. they run real quite and start making some power and about 8mph. it is sitting in a 3ft tripod and using a 1 1/4 pipe. one of the hardest things was standing it up it is only ten foot pole but the turbine is about 40lbs and on the peak on a steal roof.
