Differentials for RC models for quadcopter

Differentials

— the differential is a special mechanism used in ground vehicles — including radio-controlled cars. It is designed to distribute power between parts rotating at different angular speeds. A classic example of the use of such a mechanism is the control of the speed of rotation of wheels located on the same axis during cornering. To avoid slippage, the wheel on the outside of the turn, moving along a longer path, must rotate faster than the wheel on the inside; the differential just provides the necessary difference in speeds. Another variety found in RC cars is the centre differential, which is installed between the axles in all-wheel drive models. It performs a similar function, since the front and rear wheels also rotate at different angular speeds during a turn.

Usually, RC cars are initially equipped with differentials, even in the Kit configuration. However, the ability to separately buy such a part may also be useful. In addition to such obvious applications as replacing an existing mechanism in the event of a breakdown, a “non-native” differential can be useful to improve the practical characteristics of a model. In particular, to increase the cross-country ability on difficult terrain, as well as for a spectacular drift, it is necessary to lock (disable) the differential; however, the stock ("stock") mechanism may not be interlocked and the applications mentioned may require replacement of the mechanism with a more advanced solution.

Also note that in addition to entire differentials, this category also includes individual parts for such modules — for example, gears and locks. And spare parts of this type are usually intended for specific models of machines.
