I can't say I ever expected anything much of it. If its not actually in the windings, as opposed to simply being an extension of them, it doesn't mean any more than the actual leads from the ESC to the motor, especially with the large gauge wires some use to connect things. You couldn't convince some racers, however. I've seen a few actually cut the wires away completely and solder the ESC right at the can. That's a little nuts, especially in a Tamiya mini class.
As for my driving, it's hopeless. Thanks for your remarkable input, guys. Without you smart folks, we'd be nowhere.
