OK James, that's the setup that i've think about. But for the lipo pack, is the 4000 maxamps is good and have good punch??
Is somebody have ever try the E-Cell??? $120.00 for a 14.8volts 4000 mAh, 25C pack
Go for the MaxAmps 5000mAh 3s pack - fits perfectly on one side of the buggy. Pair that with a motor around 3000kv and you'll be all set for a ~40mph gearing with either 16/46 or 17/46.
Go for an L size can - the crt.5 is not a light buggy for it's size and you'll appreciate the punch.
