How Do I Increase the Range of My RC Car?

Increasing the range of your RC car can be a great way to get more out of your hobby. With the right modifications, you can make your car go faster, farther, and with more control than ever before. Here are some tips on how to get the most out of your RC car.

Modify or Upgrade the Antenna

One of the simplest and most effective ways to increase the range of an RC car is by modifying or upgrading its antenna. This is especially important for cars that have stock antennas, as they are often short-range and lack the power to send or receive signals from long distances.

You can either buy a new antenna from a hobby store or modify one yourself. However, before you start making changes, it is important to understand the basics of antennas so you don’t do any permanent damage.

Run High-Gain Antennas

High-gain antennas are specialized antennas that provide increased range by focusing their signals in a specific direction. They are an ideal option for those looking to increase their RC car’s range without doing any major modifications. High-gain antennas come in two varieties—omnidirectional and directional—and both types can help increase your car’s range by up to 50%.

Upgrade Your Batteries

The battery packs in RC cars usually have lower capacity than normal batteries, so upgrading them can be a great way to increase your car’s range. Swapping out standard NiMH batteries for higher-capacity LiPo or LiFePO4 batteries can significantly improve both speed and distance. Just make sure that you buy compatible batteries for your particular model.

Change Your Motor Gear Ratio

Changing the motor gear ratio is another way to increase your RC car’s range. This involves replacing the stock gears with ones that have higher teeth counts, which will make your motor spin faster while using less power. This means that you will get more speed while using less battery power, which increases your overall range.


Increasing the range of an RC car can be achieved through various modifications such as changing or upgrading its antenna, running high-gain antennas, upgrading its batteries, and changing its motor gear ratio. With these tips in mind, you should be able to get more out of your RC car experience and enjoy longer racing sessions with greater control.
