Motor Types
Brushed and brushless motors are the only ones that exist. While some persons may argue that there are others, they all fall under the category of either brushed or brushless. The difference lies in the way the energy conversion mentioned above takes place. To make it simple, the brushed motor uses an impact to transfer the current using “brushes” made of metal. No physical contact takes place in the brushless alternative, as the motor is rotated electronically.
The Intended Audience
The focus of this article is the brushless alternative as its lack of impact and architecture makes it the better alternative of the two. As it is more powerful, it is better suited for projects that require power and speed. Note that brushless motors are also more expensive, so if you can afford the performance and you need it, feel free to pick one up.
What if the prior statement doesn’t describe you? This means you’re either on a tighter budget, you don’t need the performance or both. In this case, you’re better off grabbing a brushed motor. These motors are also better for those who are just jumping into the RC world for the first time. A good motor for you, in this case, is the Traxxas Brushed 550 motor. It is shipped with a 48P 19T with Set Screw.

Best Brushless RC Motor in 2019 – Buyers Guide
Now that you’ve seen the products, it’s time to discuss the considerations behind them that may factor into your decision.
- Application
One of the most important things in choosing a motor is the application for which it is needed. Some motors, such as the iFlight XING CAMO 2207, are suited to flight applications. While you can use a motor for something other than its intended purpose, you don’t get the benefit of the features when you. Ensure you pay attention to the designated purpose of the motor before you make a choice.
- Precision-balancing
This weighs heavily on the performance of the motor. A precision-balanced motor is a better performing motor. This engineering technique allows for efficient operation. This means that the motor can endure sustained use without compromising its smoothness or its reliability. The balancing technique also has benefits where battery life is concerned.
- Scale Compatibility
Ensure you pay attention to the scale compatibility that the motor is best suited for. An improper scale selection can present building, performance, and clearance issues for your RC project, which compromise the effectiveness of the finished product.
- Heat Mitigation
Like most electronic equipment, brushless RC motors are susceptible to heat damage. The caveat is that heat is generated within their normal course of operation. The onus is, therefore, on the product creators to put the required measures in place to tackle any issues that could arise surrounding heat. iFlight, for example, uses a multi-hole system to continuously pull heat away from the motor as it works. Pay attention to the inclusion or lack of heat mitigation measures as these could be the difference between a working motor and an explosion.
Conclusion
The question of the best brushless RC motor is not as simple as it sounds. Since the motors have different applications, it becomes a case of comparing apples to oranges. While there are some base features that are constant, for the most part, the builds are specialized based on the application.
Therefore, instead of trying to ascertain which motor stands above all others, consider your specific needs before making your selection, and choose one that best aligns with said needs. Hobbysky, for example, has a pretty neat brushless motor that was discussed above. It offers great flight performance and good flight duration. However, none of this is useful if you’re building a crawler.
