How Do RC Cars Work?

Every gaming and car enthusiast has a passion for RC cars, and they are always hunting for the most incredible RC vehicles with the most up-to-date features. Several RC vehicles get released every year, and people keep looking for the best ones to purchase and add to their collection.

However, it could be challenging for first-time buyers trying to buy the best RC car for beginners. It is because most of them may not be aware of the working mechanisms of RC cars.

This article is a detailed analysis of how RC cars work so that even a beginner can learn about these vehicles.

The various components of RC devices-

Before explaining how RC vehicles work, it is essential to talk about the various parts of the RC vehicle. Several RC vehicles are available today, but they rely upon the same basic elements. When searching for the best RC car for beginners, you need to remember that all RC cars usually have the same essential components, which are as follows:

  • Power Source- A power source is one of the essential parts of the vehicle as the entire operation is entirely dependent on the power supplied. The power source is generally of two types-batteries or fuel. Remote-control ones are mostly battery-operated.
  • Motor- Motors (electric) and engines (gas/nitro) play an essential role in every vehicle. It is because motors help in enabling the movement of all the necessary parts of the car, including the wheels and steering, for example.
  • Transmitter- Transmitters are the remote control sensor device that helps the user direct and regulate the RC vehicle’s movement.
  • Receiver- Receivers are antennas that are present in the RC vehicles. They are responsible for receiving the signals transmitted by the RC vehicle transmitter.

How RC vehicles work-

In RC vehicles, radio waves are used by transmitters to send signals to the receiver. It, in turn, causes the motor to work and perform the function as a response to the signals received. Although this sounds simple, there are some other important aspects to discuss.

  • At first, the transmitter located in the controller sends out a signal to the vehicle. This signal is of a definite frequency, usually 27MHZ or 49 MHZ. Most cars nowadays have the capacity to send out both frequencies. So the user can operate the vehicle using both.
  • Control buttons are provided in the remote, which are usually the same for most vehicles. The control buttons can make the car move forward, backward, reverse, left or right. As the user touches the control buttons, it causes the electrical sensors to send out electrical impulses. On pressing the buttons, electrical pulses are sent out. These pulses give specific responses, such as a forward or a backward movement.  More advanced radios use a pistol grip with a steering wheel to transmit direction and throttle. 
  • The receivers in the RC vehicles are continuously looking out for signals so that the car moves uninterruptedly. According to the pulses, the car components move, whether the wheels or the steering, as per the signal transmitted. The car then uses the motor and the power source to move the parts as instructed by the user.

Conclusion

Although this is the mechanism that lies behind most RC vehicles, it is important to remember that some of them have different, controllable parts. The RC planes, for example, will have separate workings altogether.
