Radio remote controls
The most important thing you need with RC vehicles is, of course, a radio control. Radio remote controls essentially consist of three components: transmitter, receiver and servos.
Conventional radio controls are equipped with either two sticks, which can be moved in two to four directions, or as so-called pistol transmitter with a knob as a steering wheel and a throttle triggwe. The integrated transmitter in the controller translates these wireless signals and sends them to the receiver, which is built into each RC model. Through this receiver, the signals of the remote control are forwarded to the servo. For this to work, the receiver must be tuned to a quartz of the same frequency as the transmitter. This determines the channel on which to send and receive. If you have any questions about this, you should follow the manufacturer's instructions. The task of the servo is then to implement the stick movements of the transmitter in steering movements on the vehicle.
