Why Is My RC Car Moving by Itself?

Are you experiencing mysterious movements from your RC car? This phenomenon is not as strange as it may seem, and it has a logical explanation.

RC cars often move by themselves because they are designed to do so.

Your RC car is likely using a process known as ‘auto-correcting.’ This is when the car’s receiver uses a signal to detect any oscillations in the motor, and then makes automatic adjustments to maintain a straight path.

This means that if the car starts veering off course, or begins to wobble, it will make tiny corrections to get back on track.

Another factor that can cause your RC car to move by itself is radio interference. Radio frequency devices such as phones, microwaves and even other RC cars can disrupt the signal between your remote and the receiver on your car. This can cause your car’s movements to be erratic, making it appear as though it’s moving by itself.

Finally, if you have an old or poorly maintained battery in your RC car, it could be causing the spontaneous movement. Over time batteries can develop corrosion or other issues which can lead to inconsistent power supply and unexpected movements.


In conclusion, there are several reasons why your RC car may seem like it’s moving by itself. The most likely explanation is auto-correcting or radio interference, but old batteries can also cause unexpected movements. If you suspect that there is an issue with your battery then you should replace it immediately.
