Your performance is very compariable to mine.....http://www.evalbum.com/preview.php?vid=1231 I started out looking for a PM motor solution with regen but was worried about heat in AZ. I pretty much over killed my design.......your solution is much more cost effective. My batteries are a bit larger and my range is a bit more......me
