Re: Tank Treads

I have to add something for the teams using tank treads...
Turning on carpet with treads causes extreme electrical loads on your control system. A tight turn is guaranteed to put drive motors into stall. Stall currents on CIM motors is 129 amps each. A four motor drive will draw 516 amps and effectively lower the terminal voltage of the battery by almost 6 volts.
