How Can I Add More Power to My RC Car?

When it comes to racing remote-controlled cars, power is the name of the game. Experienced RC racers know that having the right motor and battery combination can give them an edge over their opponents.

Although many RC car kits offer great performance right out of the box, there are a few modifications you can make to give your car even more power.

1. Upgrade Your Motor – One of the simplest and most effective ways to add more power to your RC car is to upgrade your motor. Motors are rated in turns, which indicates their power output.

The higher the turn rating, the faster your car will go. If you’re looking for maximum speed and acceleration, a brushless motor is a great option. Brushless motors have no brushes or commutators, which makes them more efficient and powerful than brushed motors.

2. Use High-Performance Batteries – Batteries provide the energy that powers an RC car’s motor and electronic components.

When it comes to batteries, not all are created equal; some offer higher discharge rates than others, resulting in more power and speed for your RC car. LiPo (lithium polymer) batteries are considered by many to be the best type for RC cars due to their high capacity and discharge rate.

3. Install A Performance Exhaust System – Just like real cars, installing a high-performance exhaust system on your RC car can help it breathe easier and increase its overall performance. Exhaust systems help reduce air resistance by allowing air to escape from the engine quickly and efficiently.

4. Tune Your Engine – Tuning your engine is an important step in getting maximum performance out of your RC car.

There are several different types of tuning you can do such as adjusting fuel mixture ratio or spark plug gap size.


These modifications can help you add more power to your remote-controlled car so you can blaze past your opponents on race day! By upgrading your motor, using higher-performance batteries, installing a performance exhaust system, and tuning your engine properly, you can take your RC car from good to great!
