The high-speed gearbox can be assembled in 11.6:1 and 18:1 gear ratios. This high-efficiency gearbox is therefore suited for very fast vehicles or other fast mechanisms that do not require high torque.
This versatile, high-efficiency gearbox lets you build one of the following gear ratios: 11.6:1, 29.8:1, 76.5:1, 196.7:1, 505.9:1, and 1300.9:1. Whatever your application, chances are that one of the configurations will do the job.
Tamiya’s double gearbox packs two independent gear trains into a compact and affordable package that is great for small mobile robots. Each side can be assembled to have one of four gear ratios: 12.7:1, 38:1, 115:1, or 344:1.
The single gearbox is perfect if you like the gear ratio options of the 70168 double gearbox but need just one motor or added flexibility in positioning multiple output shafts. Available gear ratios are: 12.7:1, 38:1, 115:1, or 344:1.
