My future is LiPo , for now i am not worried about runtime :)

The 9L on 14 cells would need a 15 tooth pinion with a strobe slipper/spur setup, or a 19 pinion with the stock slipper/spur to exceed 40 mph. It will get there pretty quick, too. This is assuming stock size tires and stock diffs.

I here you can get a pretty good deal on a BL setup from a place called http://www.rc-monster.com/ Have you looked there?:D
