Tamiya 72007 - 4-Speed High Power Gearbox HE for Robotics

The Tamiya 72007 4-Speed High Power Gearbox HE is built for makers and students to test drivetrain concepts and mechanical setups. It provides a straightforward platform to observe how gearing affects behaviour in small robotic builds.

Selectable Ratios for Experimentation

Choose from four gear ratios: 39.6:1, 47.6:1, 61.7:1, and 74:1 to match your project needs. Changing the motor pinion, adjusting the spur position, and swapping attachments lets you quickly compare performance under different conditions.

Compatibility Notes and Output Features

Designed around a Type 260 motor speed range of about 5040 to 6300 RPM at 1.5V, the gearbox also includes a 4mm threaded driveshaft and a pair of 12mm hex wheel hubs. The supplied adapter lets you fit separately sold 130 and 140 motors for greater versatility in builds.
