You should look at what frequency the cars use if you want to purchase a remote-control car to play with buddies. Can two remote-control cars share the same frequency if RC cars aren’t always great on the same spectrum?
Keep your remote-control cars, boats, and airplanes apart when using them on the same frequency, whether it be 27MHz or 49MHz. If they travel too close together, signal interference develops from crosstalk, which makes the cars stutter, stop moving, or become twitchy.
What exactly is the problem, what causes all these frequency problems, and how are they being addressed? Let’s examine all the variables, which should make it clear why you need to be aware of them before making a purchase.
Using Two Models Simultaneously
Two remote-controlled cars could share the same frequency. You won’t be able to drive both remote-controlled automobiles at the same time, though.
The TQ and TQi 2.4GHz radio systems automatically locate and lock onto the receiver that they are linked to, so you can just “turn on and drive” if one or both of your models have them.
You must ensure that your models are not on the same frequency if you are both utilizing the AM TQ radio system. Onboard the vehicle, there is a crystal in the transmitter and a complementary crystal in the receiver. These crystals regulate the frequency that your car utilizes for signal transmission and reception. Your two radio systems won’t interact with one another as long as they are operating on distinct frequencies (using various color crystal settings).For its radio system, Traxxas offers six different frequency crystal sets. You can get a replacement crystal set for your radio system so you and your friend can operate your models simultaneously if you and your friend are on the same frequency. The frequency crystal set you require will determine the part number to order.
Issues with Radio Controlled Cars and the Same Frequency
Due to having been given the same frequency by the manufacturer, there are some extremely typical concerns with sharing that will affect your experience with RC cars.
The two remote-controlled cars you have running about are unable to distinguish between which vehicle and which controller is giving the car commands, which is the main reason this affects usability.
The makers of RC cars are aware of this and do their best to offer vehicles with either of the two primary signals, giving you the option to choose the optimal RC car frequency before making a purchase.
How to Avoid Radio Frequency Interference in Rc Cars?
Let’s dive in and find out how to get racing again and how to stop remote control vehicle interference! There are a few popular strategies to help lessen or eradicate all interference from occurring while you are out racing your car!
Try to Avoid Approaching Other Rc Cars Closely
The 2.4GHz frequency allows numerous different automobiles to often race without affecting one another due to its many variances.
Although having a 2.4GHz spectrum radio does not guarantee that you won’t experience cross talk with another racer, you should move away from each other if this does occur.
In the toy sector, where radios typically operate between 27MHz and 49MHz on the MHz frequency, this can become a more serious problem.
The most distance you can walk inside the MHz range is approximately 100 feet, give or take. If necessary, you can always move 200 feet down the street to be free of an interfering signal.
Selecting Different Frequencies
There are only a certain number of radio signals that can be utilized for radio-controlled cars because they operate on radio waves. Although they don’t happen very often, you could have overlap.
Again, this is considerably easier for GHz spectrum radios because there are thousands of frequencies available, making the chances of a duplication extremely slim.
The problem is that toys for children often only exist in two frequencies, 27MHz and 49MHz. This implies that if you are buying two to play together, you need to make sure that you DON’T buy the same frequency for both.
Pick Rc Vehicles with Selectable Band Frequencies
The majority of low-cost RC cars lack the capacity to be modified or to choose a different frequency to move away from another vehicle.
For instance, a 27MHz radio controlled car would technically be on channel 4 at 27.145MHz.
Any reference to “band selectable” in the paperwork for these lower frequency vehicles indicates that there is a way to change the band that is being used.
The phrase “may be playable with up to xx additional cars” may be found on a car’s box; this is an indication that the vehicles have a switch that enables the tiny frequency difference to play together.
These can also be color-coded to make them easier to distinguish; in this instance, they align to the following:
- Channel 1 – Typically labeled Brown: 26.995MHz.
- Channel 2 – Typically labeled Red: 27.045MHz.
- Channel 3 – Typically labeled Orange: 27.095MHz.
- Channel 4 – Typically labeled Yellow: 27.145MHz
- Channel 5 – Typically labeled Green: 27.195MHz
- Channel 6 – Typically labeled Blue: 27.255MHz.
Protecting Hobby-Grade Vehicles from Interference
This is where the significant differences between a toy-grade car and a hobby-level RC car start to become apparent.
Compared to their toy relatives, hobby level RCs are far more adjustable; as a result, it is entirely feasible to replace the radio and obtain a different signal rather than being restricted.
This flexibility to customize compromises sustainability; the majority of hobby automobiles are not likely to be cheap and can frequently cost thousands of dollars.
In addition to the methods mentioned above, there may be other ways to make adjustments, such as changing the actual crystals that are utilized to transmit the signal.
Rc Car Frequency Adjustment
There are some straightforward fixes, such as the one we just discussed, and then there are changes that, in most cases, depend on good hobby automobiles.
How can the frequency of a remote control car be changed? With the more expensive hobby-level cars, you can choose to delve deeper and adjust the frequency that is responsible for sending the car its signal.
By altering the crystal, different RC cars can have different frequencies. RC supply stores are normally where one may get more crystal sets. After that, you can switch the crystals in the receiver and remote control to adjust the frequency of the car.
Changing the frequency will enable you to simultaneously control two distinct remote-controlled cars. You should do your research before buying an RC vehicle because you can’t do this on all of them.
There are six channels in the 27MHz and 49MHz frequency ranges (also used for miniature RC vehicles), 10 channels in the 50MHz frequency range, and a lot more options for hobby-level cars (requiring a radio license).
In addition to this, there are 30 channels in the 75MHz band that are accessible in the US for hobby-grade RC vehicles.
The Various Frequencies for Rc Cars
Which type of car you need to buy and which signal is best for your needs will depend on how you intend to use your RC car.
The majority of the time, a hobby-grade car will be the better option because it allows you to make changes and improvements over time rather than being constrained to the same low-quality, nearby play that a toy car does.
27 Mhz and 49 Mhz for Rc Cars
As we have covered, the two main signals are those where cross-talk is most likely to occur and restrict the enjoyment of other drivers.
Toy RC cars are always sold in one of these two ranges, typically far more in the 27MHz band.
2.4ghz Rc Car Frequency
You don’t need to worry too much about interference when using a remote-controlled automobile that operates on the 2.4GHz frequency. This is mainly because GHz transmitters are designed to connect with the signal receiver.
Based on their particular electromagnetic signature, this is. As a result, you won’t experience any RF interference amongst the various GHz-powered remote-control car models.
You will be unable to complete the task if you attempt to control two different remote-controlled vehicles using the same transmitter.
Final Words
Never choose an MHz frequency car when shopping for an RC car to drive as a hobby since there are simply too many problems caused by competition on the band. Instead, put your attention on a better-quality vehicle that operates in the 2.4GHz band to guarantee that you may race whenever you want, wherever.

Can you run two 2.4 GHz RC Cars at the same time? Each receiver can only be coupled (also known as binding) with one transmitter at a time since each transmitter has a distinct signal ID. Simply bind a receiver to each transmitter to use both transmitters simultaneously on different vehicles.
