How to Change Frequency on Remote Control Car?

Two RC cars with the same frequency are feasible. You will not be able to manage both RC cars at the very same time. So, all you have to do is change the frequency of one of your RC cars in this case. So, do you know How to change frequency on remote control car?

While some cheap RC car comes with a fixed frequency range, most RF transformer of RC cars has frequency adjustment feature. So, you can change the frequency on remote control car. Changing frequency on an RC car is not too much challenging.

This article is going to discuss all the processes associated with RC car frequency changing. We’ll discuss all the techniques step by step that will help you to do the task easily. So, continue reading this article if you want to change the frequency of your remote-control car.


What frequency do remote control cars use?

The majority of RC vehicles use one of two different frequencies: 27mhz or 49mhz. This is because the FCC has allocated these two radio frequencies for remote control of small appliances like hobby RC cars, garage doors, as well as lighting systems.

Some sophisticated RC models function at 72MHz or even 75MHz. Although these models are much more complex and uncommon than the RC vehicles, most enthusiasts would encounter them.

RC vehicles use a standard radio frequency because if they are set to a different frequency, they will not work. Depending on which equipment is impacted by radio frequency interference, the interference might be harmful. As a result, you should make sure that altering radio transmissions on any RC car you use is allowed.

What Do You Need to Change the Frequency on an RC Car?

The problem with swapping frequencies is that you’ve two RC vehicles on the very same frequency? If so, then there’s a possibility you won’t have to make any major changes to the car. Some RC vehicles have configurable bands, meaning they can run on a variety of frequencies only within the 27MHz range.

 You ought to be able to change the car’s chosen frequency to one of the other frequencies if you have selectable bands. The two cars should not conflict with each other’s functioning as long as they operate on distinct channels within the 27MHz frequency band.

Whether you’ll be able to change the frequency of a transmitter so that it may be correctly received by such an RC vehicle on the very same frequency will rely on a few distinct things. You won’t be able to alter that specific controller to operate with the automobile if the receiving board contains a crystal, but the transmitter circuit board doesn’t.

How to change frequency on remote control car?

Changing a remote-control car’s frequency is not a complicated task. You can get this job done by following some easy steps. Here we’ll show you the step-by-step tricks to change the remote-control car’s frequency. So, let’s take a look at How to change frequency on remote control car.

Step-01: Remove the Upper cover of the car

To change the frequency on an RC car, you need to access the PCB board. So, unscrew all the screws of the car and then remove the cover of the car. After detaching the upper cover, you will find the PCB that may have been screwed to the lower panel. So, unscrew the PCB to get access to the rf frequency transformer. This transformer looks like this:

Step-02: Unscrew the Remote

After accessing the car’s PCB, now you should get access to the Remote’s PCB. So, unscrew the remote and remove the upper part and get the PCB. On this PCB, you’ll also get an RF transformer.

Step-03: Change the car’s frequency first

After accessing the PCBs, now it is time to change the frequency. So, you should change the frequency of the car first. To adjust the car’s frequency, rotate the car’s RF transformer’s adjustment screw slowly using a screwdriver. All you have to do is Turn the screw clockwise 2 or 3 times.

Step-04: Adjust the Remote’s frequency

After changing the car’s frequency, you should now adjust the remote’s frequency. So, turn on your car and get the remote to your hand. Now, rotate the remote’s RF transformer adjustment screw until the car is started. You may have to turn the screw multiple times.

You should rotate the adjustment screw while holding any button on the remote. This will make it easier for you to understand while the car start. When the car starts, you can ensure that now the car receiver is compatible with the remote and you completed the job successfully.

Step-05: Screw the car and remote

Now screw on both the car and the remote and enjoy the new performance.

Does changing frequency make RC cars faster?

Changing the frequency of an RC car will impact the remote-control connection. It will never influence the speed of an RC car. So, changing the frequency will improve the remote control, but it has no impact on the speed. There are several effective things you can do to improve the speed of an RC car. If you are interested to speed up your RC car, then you should Upgrade the RC Car.

The FAQs:

Why are all RC cars 2.4 GHz?

When running your RC vehicle near another’s, their controller may interfere with yours, causing a significant disturbance. This interference is caused by the use of a subpar MHz frequency. A 2.4ghz radio frequency, on the other hand, eliminates this issue since it is immune to signal interference.

Can you use 2 2.4 GHz cars at the same time?

Yes. You may simply “turn on and also drive” if both of your RC cars are compatible with the TQ or even TQi 2.4GHz radio transmitter. The TQ as well as TQi 2.4GHz radio signal find and latch onto the receiver to which they are assigned.

Can I use any remote for my RC car?

Technically, most radio receivers would suffice, but ground vehicles such as automobiles and boats must utilize a distinct frequency band than airplanes. Both the radio signal and the receiver must be functional with one another. They can, however, control practically any servo.

What is the average speed of an RC car?

A well-made ordinary hobby RC vehicle should be capable of reaching speeds of up to Seventy miles per hour. A customized or drag RC, on the other hand, has the possibility to achieve speeds exceeding 100 miles per hour.

What Does 2.4 GHz Mean for RC Cars?

The radio frequency of an RC vehicle is referred to as 2.4 GHz. The radio frequency utilized by an RC vehicle is measured in gigahertz (GHz) as well as Hertz (Hz). Using such a 2.4ghz radio frequency for the RC vehicle has a lot of benefits.

Wrap Up

Do you want to know How to change frequency on remote control car? Changing the RC car’s frequency might be difficult, but it isn’t impossible if you follow the right tricks. Here we discussed the step-by-step processes of changing frequency on remote control car. By following these processes, you will be able to change the frequency of your RC car easily.
