Also, speaking of RC, anyone here ever seen silver windings on a motor before? The resistance is significantly lower, and dissipates heat much better than copper. That should mean even less of a penalty, if any, for high amp draw. I've seen 1:28th scale RC cars (xmods, mini-z) that have silver wound 130-sized motors that would run 60 mph actual speed, where a copper wound motor with the same setup would struggle to break 45.
