RC remote controls + Receivers
Remote controls, also known as RC, are used to operate remote control models. And the joystick is used for steering. The RC then transfers this via analogue with 27 and 40 MHz or digital with 2.4 GHz or 5 GHz to the right receiver. You just need to make sure the transmitter and receiver have the same frequency and radio protocol. Remote control operation comes in a number of guises but the gun transmitter and the handheld transmitter are the most common. The number of channels determines the maximum amount of motors or servos you can control.
