Well I found a kit and it should be here tuesday. I also got a MM2 2200Kv. My spur gear is 46 teeth. I'm wondering what pinions I should start with. I'm thinking 19 or 20 but I'm not sure. I will be running 3 cell at first until I can save a little more and buy 4 and 6 cell with a new charger. Either way I need to get some pinions that will cover the range.
