Differential gears are a common feature in full-size vehicles and Tamiya R/C models, allowing smooth cornering by balancing inner and outer wheel rotation speed during cornering. The transparent case lets you check how inner bevel gears mesh and work together while metal 3mm hex shafts transmit power. This unit can be combined with separately sold Universal Plates and Universal Arms in the Tamiya Educational Construction Series.
Includes a transparent case, low-friction gears, hex shafts (50mm x3), screws and grease. Gear ratio = 3.17: 1
