When your running 10 cells, you aren't worried about getting a little bit more voltage out of them. And I have seen a tc3, 4wd, running a brushless motor and 10 cells(in parallel) clocked at 83 mph. It was a VERY fast car. Think about it, for the money, you can put in 10 cells in series, and a a low turn motor and easily push 60. It actually very cheap to make elctric sedans go fast, unlike nitro cars which require hundreds of dollars to get the speed up. If you are looking for somthing cheap and fast an electic tourer is the way to go, even though you can go faster w/ a nitro.
