To make the most out of your RC cars, you need to learn about radio frequency interference. If two remote-controlled cars are set to the same frequency, they cannot be operated at the same time unless there’s a radio jammer.
How do you change the frequency of your RC car? Some models can have their frequencies changed with RC crystal sets. With a crystal set from an electronics store or RC supply shop, you can exchange the crystals in both the receiver board and the remote control to set the car to a different frequency. Some RC vehicles also have an option to change frequencies built into the vehicle as well.
There are a few measures you should take to modify your RC car’s frequency, including the right tools and knowing what frequency you want on your model. Keep reading for more details.
RC Frequencies and What They Mean
To learn how to change the alarm frequency on an RC car, you need to know a little bit about radio control. Radio control is used to remote control a variety of small motorized vehicles, from RC cars and boats to helicopters and even surveillance drones.
How to choose the best remote control car battery
When the RC vehicle is touched with the controller, data is transmitted and received by the vehicle through a radio transmitter.the radio receiver is the part of your remote control that receives signals from a base that creates signal waves.
RC vehicles receive radio signals that deliver information to the motor.the motor in an RC vehicle controls its wheels, propellers, etc. by transforming fuel or electricity into mechanical energy.
The power source can be either battery-operated or fuel-based, depending on the motor.for an RC vehicle to function, four main components need to be in place. The radio transmitter in the remote control sends out a frequency to the receiver in the RC vehicle, either activating the motor electronically or controlling the flaps on an open carburetor.
Are you wondering which frequency remote control cars use?
Generally, RC cars operate on either 27 MHz or 49MHz. These are preset radio frequencies designated by the FCC for remote control use for hobby RC vehicles, garage openers, and lighting systems.
Rare models of RC vehicles are designed to serve more experienced hobbyists. The RC cars that most people have exposure to operate at a frequency of 72MHz or 75MHz.
RC cars are on a standard radio frequency because if they operate at a different frequency, this can interfere with other signals like those used in television, wireless radio, and other forms of communication. Depending on what devices are affected by the interference, it can be potentially dangerous.If you want to change the radio frequency, always check with the FCC first.
What Is The Purpose of RC Controllers?
The RC controller operates off a different power source than the RC car. The standard power source for the controller is a 9-volt battery, while the RC car can be powered by rechargeable lithium-ion batteries or fuel-based systems.
Once the RC wirelessly receives electric pulses, the car will move forward or activate the brakes and steering.It is important to change the frequency on both the transmitter and receiver device. Otherwise, the frequencies won’t transfer correctly.
How to change the frequency of a remote control car?
The “crystal in the transmitter and receiver” is an important parts of RC cars systems that determines its frequency. The name has a ring of magic to it, but there is an answer to how this all more scientific works.
A piezoelectric crystal is used in radio frequency to switch between electrical signals and mechanical ones. The crystal can detect RF signals and convert them into a form of mechanical energy, which is useful for the receiver.
Technology in radio crystals is well-known and is a type that has batteries, time, and material. Radios have radios inside them.
Crystal sets can be used to change the frequency of an RC car, so you might want to keep one with you if you plan on frequent use.
27MHz remote control car: What does it mean?
Common frequencies in RC vehicles include 27MHz and 49MHz. These are the two standardized frequencies, as well.to avoid having both RC cars suffer from RF interference, one car should be set to a different frequency. By doing this, it becomes easy to use both vehicles simultaneously without needing to worry about the noise created by the radio frequencies.
One of the biggest problems associated with RC cars is interference from other RC cars. This problem is addressed by changing the wavelength frequency being used.
What do you need to know before you change the frequency on an RC car?
If you find that your RC car combos are crashing because they are on the same channel, there is a chance that you don’t need to change frequencies at all. Some RC cars come with selectable bands and these vehicles operate at a variety of frequencies. Six common bands utilized in the United States include 27MHz.

If you flip the car’s automatic frequency from the default to a different band, then it shouldn’t interfere with other radios.
If you’re trying to modify your transmitter so that it can be accurately picked up by a receiver, the success of your modification will depend on how much circuitry is on the transmitter and receiver. For example, if the one thing you’re modifying is a controller, but the other is missing its crystal circuit, you won’t be able to get the two to broadcast signals at the same frequency.
Unless you’re willing to modify the coil as well, you probably won’t be able to get the frequency of your RC car back in sync.
A controller can be operated at a set of frequencies, which are labeled on the inside of the circuit board.It’s important to note that to change the frequency, you’ll have to be knowledgeable on how frequencies work. As an example, in most RC cars there is a default 27MHz frequency that needs to be changed to 49MHz. When opening your remote control, be careful not to break it because many cheaper models are made up of sealed units.
What is the frequency of remote control cars?
If two RC cars are on the same frequency, the vehicles can’t differentiate which car the signal is intended for.when there are 2 or more RC cars in a small space, using a different frequency for each car will allow them to race without colliding. To do this, set each car to one of the frequencies at 27MHz.
How to Change the Frequency on a 2.4GHz Remote Control Car
Some RC cars run on a gigahertz frequency, rather than MHz. There are two major benefits of using gigahertz comm. They work better with other electronics and can transfer data up to four times faster.
The higher the GHz frequency, the longer the range of a remote control device. RCs operating in a frequency of 1GHz are less likely to be interfered with since there is only 1/1000 of the interference of RCs that operate at 27MHz. 2.4GHz RC models don’t have to worry about interference because they use electromagnetic signals.
How to Convert RC Car Frequency from 27MHz to 49MHz
You can’t change a car’s frequency with a crystal set, because that only adjusts minor details like reducing interference.It costs more time and money to change the frequency of RC than it is worth. The work that is required can be complicated, both in terms of rewiring and replacing components.radio control systems have a limited range and frequency, even if you can change them from one to the other.
How to Upgrade the Radio Equipment on Your RC Car
Some people might want to upgrade the radio equipment in their RC car rather than buy a new one. They might do this for sentimental reasons or because they want to customize the car.
Some improvements you can make while changing the frequency at which an RC car operates include:
Converting wheel-and-trigger RC controller to stick radio controller.upgrade to a more dependable brand to reduce the chance of your equipment breaking down.

Is adjusting the Radio Frequency in RC Cars Safe?
Radio waves are a form of radiation, and potentially dangerous for you. However, environmental radiowaves are non-ionized and pose no threat to your health.
Radio frequencies have no damaging effect on people. These frequencies are found in remote control cars and have yet to cause any harm.
In modern society, we are surrounded by electromagnetic radiation all of the time because of our culture’s use of wireless technologies.
Before attempting to change RC frequencies, educate yourself on the process.
RC cars are hard to modify and will require electrical engineering prowess. If you’re planning on changing sync frequencies, make sure you have the right knowledge before trying anything new.
For some RC cars, conversion to a different frequency is as simple as flipping a switch. For those that don’t name separate bands in their settings, you can use a crystal set. Converting a vehicle to an independent frequency requires more electrical knowledge than changing channels.
