Differential --

A system that transfers power equally from a shaft input to shaft outputs. A differential (or ""diff"") allows the outside wheel of a car going through a corner to travel farther than the inside wheel, preserving corner speed and efficiency. There are two main types used in radio control cars: Ball Differentials or Gear Differentials. Ball differentials should be initially set to the kit specifications: with HPI kits, the diff should be set so that the pulley is not be able to be turned with two flat head screwdrivers or Allen wrenches slid through the outdrive. A different type of differential is the One-Way Diff, which uses expensive one-way bearings to control wheelspin.
