The T-2000 is great, but you are stuck with 27Mhz AM technology. If you want to use your own FM or spread spectrum receiver, then the Sabertooth 2x10 RC provides the same capability and more options: [link]http://www.dimensionengineering.com/Sabertooth2X10RC.htm[/link]

With the Sabertooth, you can control the left track with the left stick and the right track with the right stick or steer the tank using the right stick only via mixed mode.
