The Tamiya 69910 Twin Motor Gearbox is a compact teaching and prototyping unit that exposes its internal mechanism through a clear ABS resin housing. With two independent Type 130 motors, builders can experiment with differential drive and alternative motion setups while watching the gears in operation.
Its reinforced plastic construction and snap-together assembly allow quick builds and iterative changes. The unit supports three distinct gear ratios - 16.6:1, 58.2:1, and 203.7:1 - and uses left and right 3mm hex output shafts so it can be integrated into many Tamiya construction sets and small robotic frames.
