The Novak stuff only handles up to 7 cells, so you won't be able to get too crazy with that.
Both the Tekin R1 (which isn't out yet) and the Mamba will run on 3-cell lipos, which you'll need to get the speeds you're looking for. The Tekin is going to be more money than the Mamba, but it will have more tuning options, mainly used for racing.
In the end, the Mamba is probably going to be your best bet, and best bang for your buck.
