OK, I've not looked at the 2004 version.

The 2011 version has a "Speed Loss Constant" and a "Drivetrain Efficiency". (see attachment)

The "Drivetrain Efficiency" affects the Wheel Stall Torque but not the Max Speed.

The "Speed Loss Constant" affects the Max Speed but not the Wheel Stall Torque.


With a 10:1 reduction and 4" wheels, the CIM's free speed of 5310 rpm corresponds to a vehicle speed of 9.27 fps. The purpose of the "Speed Loss Constant" in the 2011 version appears to be to allow the user to de-rate the vehicle max speed calculation to better match reality.
