Learning the most basic techniques in fixing an RC car that won’t run is very important for it allows you to perform troubleshooting by yourself. It will also enable you to reduce the expenses incurred just to have the vehicle fixed.

To do this, all you need is to conduct some online research as to how the troubleshooting is done by checking some instructional videos and articles. You can also try doing any of the tested and proven procedures provided below.

1. Check the RC car’s power switches

The most basic RC car troubleshooting technique that you should do in the event that your RC vehicle won’t run is to check the power switches. To do this, check the power switch of the car and that of the transmitter.

Always bear in mind that the vehicle and the controller must communicate to deliver their respective functions. So in order for these to communicate, both of them should be turned on.

Since checking the power switches of the vehicle and its transmitter is very important, make sure you know where these switches are. Although most RC car models are equipped with switches that are visible, there are models that come with hidden switches.

If this is the case, you need to have the appropriate tools such as a flashlight in order to see whether it is turned on or not. You might even need a particular tool just to have the switch turned on, so make sure that you have such a tool.

2. Replace old batteries

RC cars rely on batteries to provide them with the needed power to run at high speeds and perform a number of functions. But due to continued use, the batteries will eventually lose the charge needed and this becomes one of the most common reasons why the RC car won’t run even when turned on.

Given such information, it is important to regularly check the batteries in your RC car. For better results, try to use a tester that will help you identify the batteries that must be replaced.

Aside from that, avoid mixing the old and new batteries used in the vehicle. As much as possible, use the same set of batteries and replace all of them all at once, although some of these still have the charge needed to power the vehicle.

3. Reconnect worn-out wirings

RC cars are equipped with wirings that allow it to run and work according to the commands provided by the user via the controller as well as obtain the needed power from the batteries.

But due to continued use, these wirings usually become loose or can become broken. As a result, the vehicle will no longer work or run as expected. Due to this, it is important for you to check the car’s wirings regularly.

4. Reset the car’s gears

Aside from wires, RC cars are also using a number of gears that allow it to run and do other functions. In fact, the car’s running mechanism relies heavily on gears.

Therefore, when any of these gears slip, you will automatically hear a grinding noise. If you hear such a noise or the car still fails to run after doing some troubleshooting, try to check and reset the dislocated gears if there is any.

This can be accomplished by opening a specific area where the gears can be found. To do this, you might need to remove some screws and other components that tend to cover the gears.

Make sure to remove and return these properly for failure to do so would definitely affect the vehicle’s performance. In the event that you notice that the gears need replacing, have them replaced immediately to avoid further damage.

5. Check the transmitter and frequency used

It is also important for you to regularly check the transmitter and frequency used in your RC car. This is because the car will surely not run if the transmitter and frequency used is different from what is required.

To do this, take a closer look at the transmitter and make sure that it is the unit that was sold along with the vehicle.
