There is enough torque to spin up the wheels with this particular motor at low speeds, even with a top speed exceeding the rest of the cars on track by a good margin. I've been running the throttle to 80% so I don't have a crazy speed advantage. I think you might get away with setting up for the biggest track in the country and still have more than enough low end punch for the tightest track. That remains to be seen. Otherwise, rather than changing gearing it would be a case of changing stators. Not a major issue with these complete motors selling for under a tenner each.
