[RC-Monster Mike]

First off, I would like to welcome you to the RC-Monster forums! Now, on to the questions:
What size/weight is the vehicle in question? Are you absolutely SURE you need two motors? Two motors woud require two speed controllers (one controller could in theory run two motors, but it isn't a good idea and it wouldn't likely work as well as a single system or two single systems together). POerhaps you could give us some details on your project and we can discuss a few options or suggestions.
