Re: 6 CIM Drivetrains... What's Your Experience?

In order to take advantage of the extra torque, do you need some form of traction control? Are you using a PID loop to control the voltage ramp? Are you imposing an open loop ramp on the driver or motor commands? Do you monitor motor currents for stall? Do you simply let the wheels spin and degenerate to the kinetic CoF for a small time?
Mathematically probable increases in acceleration and usable speed (even without any fancy effects). Is the increase worth the cost to most teams? Probably not. Certainly there are some teams where it is worth the cost however.
