For any RC Truck enthusiast, the thrill is not only in owning and driving a good-looking mini version of a life-sized monster truck but also in the speed and power of the RC Truck as it flies around the course!
Brushless motors provide speed and performance enhancements over brushed motors for RC Trucks. The fastest RC Trucks on the market at the moment that use brushless motors are:
- The Traxass X-Maxx
- The Traxass Unlimited Desert Racer
- The Arrma RC’s AWD Senton 6s
These days, if you ask any RC enthusiast which motor is the best, you will undoubtedly hear the same answer – a brushless motor! A brushless motor has superior technology, and thanks to its reliability and longevity, this electric motor is quickly becoming the motor of choice for controlling powerful RC Trucks. In this article, we discuss the benefits and speed of brushless motor-powered RC Trucks.
Why Brushless Is Faster Than Brushed Motors In RC Trucks
Essentially, the most significant difference between a brushed and a brushless motor is the way they are constructed. The working principles are similar but, while the brushed motor uses a brush to convert electricity in the motor, its brushless equivalent does not.
This means that the brushless motor is more efficient and overall more powerful than the brushed motor. Brushless motors offer a higher torque to weight ratio and increased torque per watt of power input. The result of all this power and efficiency in a scaled-down version of a life-sized truck is – speed!
When it comes to purchasing a motor for RC Trucks, consider these before you decide.
- A brushed motor has lower power efficiency – between 75 and 80 percent
- Lower efficiency because of the design of the brushed motor causing the brushed motor to have lower speed ranges than a brushless motor
- Heat loss is higher because of the shifts of the shafts, the friction of the brushes, and commuters adding to lower efficiency
In comparison, before you purchase a motor for your RC Truck, consider this motor:
- A brushless motor has higher efficiency than a brushed motor – between 85 and 90 percent
- Brushless motors are significantly faster and more powerful than brushed motors due to their higher efficiency
- Higher efficiency means lower maintenance and higher run times for RC Trucks
- Brushless motors operate effectively at all speeds within their rated load
Are Nitro Motors Faster Than Brushless Motors?
Currently, brushless motors are faster than Nitro! This is because brushless motors are equipped to handle higher voltage than brushed motors and, with a higher voltage supply, brushless motors mean an RC Truck can race at extreme speeds – even faster than Nitro powered RC Trucks!

How To Tell If The RC Motor Is Brushless
If you cant decide if your RC Truck has a bushed or a brushless motor, this is how you can find out:
- A brushless motor has three or more wires leading from the Electronic Speed Control (ESC) to the motor
- A brushed motor typically has a black negative and a positive red wire
- With brushless motors, the ESC changes the power signals that are sent along the three wires
The Fastest Brushless RC Trucks
While there are many exciting brushless motor powered RC Trucks available on the market, we have limited our choice to these xxx RC Trucks:

Ultimately, the choice of the motor in your RC Truck depends on what you are trying to achieve. If you want high-power and high-speed, then a brushless motor is the way to go.
If you are happy to drive at a controlled, low speed with occasional bursts of high speed, then a brushed motor will suit your needs.
A brushed motor RC Truck would be ideal for the beginner who is learning how to handle the power of an RC Truck without too much outlay but, for the more advanced driver who has the need for speed, a radio-controlled, brushless motor powered RC Truck is the only option!
