              Hi All,
      Reading my Renewable Energy World mag I found this interesting article on swept back semi flexible WG blades though in huge sizes applies somwhat to ours and talks about how mine works though I did mine 30 yrs ago, well before they 'discovered' the same features . Note how they mention it increases low wind performance, widens preformance range and decreases high wind stresses, weight just as I've been saying here.
      Hopefully it'll just come up. It's in the WG suplimental in the back part on page 5 IIRC.  Enjoy
