How do RC cars work? Is it any physics behind this

This is a pleasurable and exciting activity to use  An electric RC car for the play. As RC cars are so simple to drive but the mechanism of working of RC cars is not so simple. Electronics in the form of Physics have been involved behind it. In this article, we will look at how RC transmitters and receivers work, how to program a remote control to an RC car, parts of a remote control car, how does RC car steering work, how to do an RC boat work and the advantages of remote control cars. 

How do RC transmitters and receivers work

The RC cars are operated on radio sets. Radio sets are a transmitter. This transmitter is helpful in delivering the signal to the operating cars. 

The electronic RC car used a two-channel radio system.  

This is necessary to provide the transmitter with a power source. This power source is in the form of a battery usually this is a 9-volt battery. If the power source is absent or disconnected the translator will not be able to emit signals.

Different numbers of pulses emitted by the transmitter in the form of signals decide the movement of the car or any vehicle. 

What’s the number of pulses transmitted to the receiver to translate it to perform the desired motion.

6 Different types of motion

A normal transmitter omits six different types of motion signals. The first is the simple forward motion second is the simple reverse motion third is forward motion but in the left direction fourth is forward motion but in the right direction, the fifth is reverse motion in the left direction, and finally, the sixth one is the reverse motion but in the right direction

As the number of emitted signals changes in the form of pulses the movement of the received vehicle will also be changed. 

  • The forward motion requires 16 pulses
  • The reverse motion requires 40 pulses 
  • The forward motion in the left direction requires 28 pulses
  • The forward motion in the right direction requires 34 pulses 
  • The reverse motion in left erection requires 52 pulses
  • The reverse motion in the right direction requires 46 pulses 

How to program a remote control to an RC car



This is the step by step guide to program a remote control for an RC car

  • Place the car on a smooth surface
  • Remove the canopy of the car.
  • Try to find an empty fly lid. Nothing should be plugged into it.
  • This is actually the bind port
  • You will get a band plays in the product packaging of your car.
  • Attach speed in the empty fly lid
  • In the meanwhile, the battery should be disconnected and the transmitter should be in an of state
  • Once the band play is fitted in the fly plug this is the time to plug in the battery. 
  • Turn on the car. Little green light will turn on and start flashing.
  • Turn on the transmitter before turning it on locating the bound button on the transmitter
  • Push the compound button for a couple of seconds.
  • Now you can release it.
  • The pattern of the light flashing on the receiver will change.
  • This will become solid.
  • If you are using a surface computer or a spectrum computer then the burning process will be relatively easy.
  • Turn on the spectrum computer. 
  • Click the roller button once.
  •  A list will open.
  • Scroll down the roller till you find the bind option.
  • Click the bound button and wait for some time. 
  • Till the bonded option appears on the remote.

How does RC car steering work

Usually, the RC car is fitted with two motors. One motor drives the rear wheel. The other motor is responsible for turning the car left and right. 

The front motor on receiving the signal takes appropriate action and moves the car right or left.

How does an RC boat work

The RC bored words nearly the same way the RC car works. Two motors are present in a boat. one motor attached to the shaft will drive the boat. The other is attached to a Keel or rudder.

The second motor is to provide the direction. The board will move towards the right or left. 

All of these motors and the power source are concealed in a waterproof case.

Advantages of the RC Cars

RC cars provide a number of advantages

  • These sharpen the memories and the response of the individual
  • These provide you with the feel of the adventure without actually involved in the danger.
  • This provides you with the training of risk management without actually involving you in the risk. 
  • This is a great way for the kids to learn driving and make driving responses. 


Final words

Although the RC car looks simple there are many advantages of the RC car. This will sharpen your memory and make your responses active.


For most of us, this is the first toy that brings us to the world of adventure. This really makes this life beautiful for us. It involves us in the world of adventure without getting us involved in the danger. If you find this information helpful, you should also check Best Off-Road RC Cars in 2021.
