Exactly the same as a modern car, soft suspension is needed and its radio-controlled models-copies. After all, the impact of the model on the ground or, conversely, jump over a depression in the road surface lead to vertical oscillations of the wheels of the car that is transferred to the axles and the body. Hard suspension a strong impact on the wheel during motion leads to a separation from the road the entire model. To avoid this soft suspension allows the wheel.
When using the underlying strength of the perturbation from shock takes on only the wheel, but it starts to jump like a ball and long calms. At each jump, the wheel momentarily loses contact with the track, and if it occurs in the moment of turning, the drift model is inevitable. To reduce the duration and number of vibrations of a wheel, it is necessary to complicate the already difficult design radio model, using the dampers, or as they are called, hydraulic shock absorbers. There are two types of such devices — symmetrical, in which stroke up and down sedentarian the same, and asymmetric, where the movement towards the compression of the spring occurs almost freely, and in the opposite direction slowly.
