New “interior” picture and some more features and specification have been release from Schumacher on its CAT SX



  • 3 belt transmission with efficient low tension belts running on large size CNC machined pulleys.
  • Adjustable internal transmission ratio (2.4, 2.6, or 2.8:1) to optimise ratio for brushed or brushless motors.
  • Motor rotates the same direction as the wheels creating a car with superb jumping responsiveness and no torque steer effect as is common with shaft drive cars.
  • Super free ball diffs with silicone nitride balls, pro spec thrust bearing, and lightened steel outputs.
  • Strong steel universal joint driveshafts.
  • Smooth twin pad slipper clutch with easy access adjustment.
  • Unique clamp motor mount to fine tune weight distribution, and allow motor changes without affecting gear mesh.
  • Industry standard wheel fittings.
  • Eccentric bearing housings for adjustment of belt tension and diff height.
  • Layshaft or front one way option. Overdrive front pulley option.
  • Internal gear cover.



  • Optimum weight distribution with ‘4+2’ NiMh batteries or stick pack lipo layout.
  • 2.5mm aerospace grade carbon fibre chassis and top deck.
  • Horizontally split transmission housings for ease of maintenance and diff access.
  • Ultra narrow chassis design to minimise grounding on roll.
  • Rigid servo mount directly onto transmission housing for precise steering.
  • Dirt protected with tight fitting body and undertray.
  • O ring wing mount system to avoid crash damage.
  • Purple titanium turnbuckles included.



  • Class leading suspension geometry with durable components and a huge range of adjustments to set up your CAT to any track conditions.
