The Tamiya 72007 4-Speed High Power Gearbox HE is a versatile drive module for STEM and hobby use, giving builders the tools to learn gear dynamics and customise output characteristics. It is compact and designed for easy experimentation.

Four Gear Steps for Tuning Output

The gearbox supports four gear steps: 39.6:1, 47.6:1, 61.7:1, and 74:1. Swapping the motor pinion and changing the spur gear position or attachment lets you alter speed and torque to suit different tasks and terrains.
