you could try punching in your hub, wheel size, custom battery (to match those headway cells you are running), and a base controller to see how it dose on a flat or on different hill grades
The simulator doesnt have the 5400 series motors on it. Im not using Headway pack on this motor. I will be running somewhere in the neighborhood of 135V Lipo with a 24 or 36fet controller. I need to know the RPM per V to help me determine what voltage I will run.
