The Tamiya 72101 set is aimed at model builders and classroom robotics projects. It supplies two geared 380K75 motors matched with sponge tyres that give good traction for small-scale drive trials. The 380K75 runs on DC7.2V with an unloaded speed of 242 rpm and a maximum torque of 5.0 kg/cm, so the pair can support an estimated combined mass up to about 4kg for demonstrations and tests.
