I am designing a vehicle that will carry 7000 lbs with a dual motor set up using the motors as differential steering. Is there anyone who would be willing to talk to me about how smooth these controllers are with differential motor steering and the best R/C setup to use in this vehicle?

The controller has been used with some very heavy robots. See the one with the tank tracks that shows up in the home page picture rotation.

The challenge is the amount of amps, which in this case is tightly related to how much geared down your motor is.

Consider simulating your robot with the Electric Drive Train simulator at www.enigmaindustries.com/EDTSim.htm

This will help you determine the power your robot is likely to draw.
