Tamiya 89903 Mechanical Racehorse Finished Model - STEM Series Display Kit  [89903]

Quick look at the Mechanical Racehorse

The Tamiya Mechanical Racehorse finished model joins the STEM Series as an accessible demonstration model for mechanics and motion. As a finished unit, it lets users study how linkages and gearing produce realistic leg movement without a full assembly process.

Motion and adjustability

Front rollers provide low-friction guidance while the rear legs use grip pads for traction. Those rear grips can be adjusted to suit different floor conditions, and the back legs offer two link-rod mounting positions to change the gait style.

Technical features

Driven by a Type 130 motor and a 16.6:1 gearset, the model handles minor slopes such as those found on small junior tracks. The simple screw and wiring layout makes inspection and minor servicing straightforward. Note that one R6/AA/UM3 battery is required and is not included.
