RC Glossary

Gear Differential (Gear Diff) --

A differential that uses a series of gears to provide the differential action, allowing one wheel to rotate more than another in a turn. Gear diffs are harder to adjust than gear diffs but are much easier to maintain, because they must be sealed to keep the grease inside from coming off the gears. Tuning a gear diff can only be accomplished by changing the weight (viscosity) of the grease inside the gear diff case. The looser (to a point) a diff is, the more traction there is at that end of the car. To start tuning your car, set the ball diffs to the same tension at each end, and use the diffs only to fine-tune the car. Do not change the settings of your diffs first.
