Hi Mike,
I've just answered you on Slot list but I thought I'd post it here as well.
I'm no expert but it's all to do with the resistance of the windings of the
motor. A powerful motor has thicker wire and less resistance so it will need
a lower ohm controller, it will also draw more current. If you race a
variety of motors you might need several controllers. There are electronic
controllers on the market that will cope with all motors but they are
expensive but perhaps cheaper than several others. They generally give finer
control.
Hope this helps,
Cheers,
John
