Are you looking to boost the performance of your Traxxas TRX-4 without breaking the bank? Upgrading to a brushless motor is one of the best ways to achieve this goal. Brushless motors are more efficient, powerful, and durable than brushed motors, which are installed in most stock RC cars. The TRX-4 is a popular off-road vehicle that can benefit greatly from a brushless motor upgrade. In this article, we will explore the benefits of upgrading to a brushless motor, factors to consider before making a purchase, top budget brushless motors for Traxxas TRX-4, installation process, maintenance tips, comparison of brushed vs. brushless motors, and answers to frequently asked questions.

HOBBYWING Quicrun Fusion SE – best budget motor

The Verdict

The HOBBYWING Quicrun Fusion SE is by far the best system for the price. The Pro Ver. is nice as well you gain more speed and bottom in control with an okay price – IMO nowhere close to the best bang for your buck at the SE.

(Recommended) HOBBYWING Quicrun Fusion SE 540 Spec (Fusion SE 1200KV) on Amazon (Ad)
Hobbywing QuicRun Fusion SE 1200KV / 1800KV on eBay (Ad)
(Pro-Ver. cost more for a bit more performance) HOBBYWING Quicrun Fusion PRO 2300KV FOC System 2in1 on Amazon
Hobbywing QuicRun Fusion Pro FOC 2-in-1 ESC & Motor System 2300Kv on eBay
To get the most out of your Hobbwing ESC you need a program card

Here is a good video comparing (SE 1800kV & SE 1200kV) by Crawler Canyon YT.

Note: Usually lower Kv / more turns are better – “Well” if you have fewer rules. with lower Kv you have more voltage, gear, and efficiency range. For example – many times with lower Kv you can get near equal wheel speed with lower temp, more torque, and longer runtimes. not to count you can run a smaller and less amp / C rating battery (you can get away with a cheaper battery)… but you must run more voltage to achieve this!!!

Video showing comparing Fusion SE vs Fusion Pro vs Spektrum Firma.

Note: The Fusion Pro has much better control in the startup / low rpm and is a better pick if you’re not on a budget – The Fusion SE works well on startup / low rpm for half the price of the other two the one in the video is Fusion SE 1800kv for a bit more speed. Still recommend the Fusion SE 1200kv it’s a better deal and has better low startup / low rpm control (you do lose a bit of top speed)

Why Upgrade to a Brushless Motor for Traxxas TRX-4? And Benefits of a Budget Brushless Motor Upgrade

Upgrading to a budget brushless motor offers several benefits for TRX-4 owners. Firstly, brushless motors are more efficient than brushed motors. They use less energy to produce more power, which means longer run times and less heat generation. Secondly, brushless motors have better acceleration and top speed than brushed motors. They can also provide more torque, which is essential for off-road vehicles that need to climb steep hills and obstacles. Lastly, brushless motors are more durable than brushed motors. They have fewer moving parts, which means less wear and tear and fewer maintenance requirements.

Factors to Consider Before Choosing a Budget Brushless Motor

Before purchasing a budget brushless motor for your TRX-4, you need to consider several factors. The first factor is the size of the motor. You need to ensure that the motor fits your TRX-4’s specifications and can handle the vehicle’s weight and size. The second factor is the motor’s KV rating, which is a measure of its speed. A higher KV rating means a faster motor, but it also means more heat generation and less torque. You need to choose a KV rating that matches your TRX-4’s intended use. The third factor is the motor’s construction and quality. You need to choose a motor that is well-built, durable, and can withstand tough off-road conditions.

Installation Process of a Brushless Motor Upgrade

Installing a brushless motor upgrade on your TRX-4 is a straightforward process that can be done with basic tools and some technical knowledge. Here is the Video…

Maintenance Tips for Your Brushless Motor

You need to perform regular maintenance to keep your brushless motor running smoothly and efficiently. Here are some tips:

Clean the motor regularly with a soft brush or cloth to remove any dirt or debris.
Check the motor’s bearings for wear and replace them if necessary.
Check the motor’s wires and connections for any damage or fraying.
Lubricate the motor’s bearings with a high-quality lubricant.
Avoid running the motor at maximum power for extended periods to prevent overheating.

Frequently Asked Questions About Brushless Motor Upgrades

Q: Can I use a brushless motor with my stock ESC? A: It depends on the motor’s specifications and the stock ESC’s compatibility. It is recommended to use a compatible ESC with your brushless motor to ensure optimal performance and safety.

Q: Will upgrading to a brushless motor void my TRX-4’s warranty? A: It depends on the manufacturer’s warranty policy. Some manufacturers may void your warranty if you modify your vehicle, while others may not. It is recommended to check your warranty policy before making any modifications.

Q: How do I choose the right brushless motor for my TRX-4? A: You need to consider factors such as motor size, KV rating, and construction quality. Research different options and read reviews to find the best motor for your TRX-4’s intended use.
