Yeah, I think I'm going to just go ahead and get the Titans off Ebay.....Unless someones has some they could spare.

And no, no ESC, sadly. It's all or nothing.

It's going to be running off one 12v battery (the stock one), I can add more and go up to 18v, something I'm pretty sure I'll do. You don't think that going up to 18v would be too much for the Titan do you?

Thanks for all the help guys.
