Cool! http://www.windynation.com/web/windtura ... urbine-kit I have a few questions: 1. Is it identical to the 500 other than the PMA, and if so why such a price difference as the PMAs are only $100 different? 2. Will all 750s come with a blue mount vs. black on the 500? 3. Any plans to offer it with larger blades vs. the 500? 4. What is the lead time?
