Raio Control Systems Help
This is a guide compiled to focus on the fundamentals of electric powered R/C car helicopters.
Radio Control System:
When you have bought a R/C model, a radio control system designated for the model should also be purchased. Most radio control systems on the market are of the digital proportional type. In short, they are called the radio. The system consists of a transmitter, a receiver and two servos, plus power supplies for the units.
The Transmitter:
Your transmitter serves as the control box for R/C models. When the transmitter is in operation, it emits signals by means of radio waves.
The Receiver:
The receiver accepts the signals from the transmitter and converts them into pulses that operate the servo(s) installed into the model.
The Servo:
Servos convert the electrical impulses from the receiver into mechanical movements. The servo motor then rotates and arm (servo horn) in a programmed direction. This movement then controls a specific model function.
Last note:
*Electric powered R/C models can use pulse width modulated electronic speed controls with integrated circuits. This eliminates a second servo and the mechanical speed control it would operate. Electronic speed controls are more efficient and require virtually no maintenance.
