Spur Gears are used on both electric Radio controlled Model cars, and Gas (petrol or Nitro) Radio Controlled Model Cars. Battery RC Cars have an advantage over Gas RC Cars in that they can easily change the modified electric motor with higher basic RPM to give better top speeds, or a lower wind motor with the same Spur Gear will give lower RPM with higher torque. Gas RC Cars on the other hand use the spur gear along with the pinion gears to set up the cars handling on specific tracks, torque and speed is determined by the engine.
