I have just received my WS2308. I like the shape and basic functions. I should run a distant communication test. I am looking for a mast solution to get it mounted on. It should be at least 24m tall and safe. I have also received today Paul Gipe's book the "Wind Power" revisited . First impression; it's great. In a manner of 30 pages read I learned more on wind power then by 3 weeks of struggle on the internet. Books are still useful.
