How Do You Use a RC Car Servo?

RC car servos are an essential component of any remote control car. They are responsible for controlling the steering and the throttle of the car. These servos can control both linear and rotational movements, which makes them very versatile and useful in a variety of applications.

In order to use a RC car servo, you must first understand how it works. A servo is essentially an electric motor with a gearbox attached to it, usually in the form of a plastic case.

Inside this case is a small circuit board with four electronic components – a brushless DC motor, a driver circuit, an amplifier, and a potentiometer. When you connect power to the servo it starts to rotate, which is then translated into linear or rotational movement depending on how the servo is wired up.

To control your RC car servo you will need two main components – an RC controller and a receiver/transmitter unit. The controller is responsible for sending signals to your receiver/transmitter unit, which then sends signals to your RC car servo.

The signals sent by the controller can either be digital or analog depending on what type of system your RC car uses. The most common type used in RC cars is digital PWM (pulse width modulation).

Once you have connected your RC controller to your receiver/transmitter unit and set up your system correctly, you can start controlling your servo by using either buttons on the controller or by using software on your computer or laptop. Depending on what type of system you have installed in your RC car you may be able to adjust settings such as speed, direction, acceleration and braking as well as other features such as temperature monitoring or battery monitoring.

Using Your RC Car Servo

Using an RC car servo is fairly straightforward once all of the components have been set up correctly. To control the steering and throttle of your vehicle you will need to send specific signals from your controller that are picked up by the receiver/transmitter unit and then sent to your servo.

Most controllers will have buttons that correspond with different functions such as forward/reverse or left/right directional control. You can also adjust settings such as speed and acceleration if necessary.

RC car servos are important components that allow us to control our vehicles remotely with precision accuracy. With just some basic understanding of how they work we can easily install them into our vehicles and use them for our desired application.


In conclusion, using an RC Car Servo requires connecting all necessary components together including an RC controller, receiver/transmitter unit and finally the actual Servo itself. Once everything is properly hooked up, one can use their controller’s buttons or software on their computer or laptop to send signals that are picked up by their receiver/transmitter unit then sent to their Servo which allows for precise control over aspects such as speed and direction.
