Introducing the Furitek UNITY PRO Brushless System compatible with TRX-4M

We are thrilled to unveil the Furitek UNITY PRO, the pioneering 2-in-1 brushless system tailored for 1/24 and 1/18 scale RC crawlers. As a leader in electronics for mini crawlers, Furitek continues to push boundaries, delivering cutting-edge technology that enhances your RC experience. The UNITY PRO combines a brushless motor and brushless ESC in one compact unit, equipped with FOC technology to provide unparalleled smoothness, powerful start-up punch, and seamless power transitions. This system is designed to meet the needs of serious hobbyists and competitive racers alike, offering a host of features that ensure optimal performance and convenience. 

Key Features

Completely Waterproof and Dustproof

The UNITY PRO is designed to withstand the elements, featuring a new enclosing case that protects against dust and water. This durability ensures reliable performance in any environment, whether you're navigating rocky terrains or muddy trails.

FOC Technology

Field-Orientated Control (FOC) technology provides ultra-smooth throttle control and consistent power delivery. This advanced technology helps maximize efficiency and prolongs the lifespan of your RC crawler.

Integrated 5A BEC

The built-in BEC with a substantial 5A output can handle the demands of high-torque servos and heavy vehicles without the need for an additional BEC. It supports multiple voltage settings (5.5V, 7.4V, 8.4V), accommodating a wide range of setups.

Separate Power Switch

A dedicated power switch allows users to place it conveniently on their rigs. This feature lets you easily turn the system on and off, preventing unnecessary battery drain and enhancing overall convenience.

Mobile App Integration

The Furicar app, available on both Android and iOS, offers real-time telemetry, live tuning, and easy programming. The app's user-friendly interface allows you to fine-tune your setup on the go, ensuring your crawler performs at its best in any condition. (Repeater module required for some features.)

FREE Lifetime Firmware Updates

Stay ahead with lifetime free firmware upgrades, ensuring your system benefits from the latest features and improvements. Our new firmware algorithm enhances startup smoothness, bringing your RC crawler to the FOC stage seamlessly.

Furitek Unity Pro

I installed this motor on a Traxxas TRX4M. It is much smoother and slower than the stock brushed motor, which would be expected.

It came with the Bluetooth lead, but honestly, it does fine just as it’s sent. The Bluetooth allows you to adjust the ESC settings via cell phone.

The motor is pretty fast on 3S with my 2spd transmission in high gear. In low gear, it’s got plenty of pulling power and can creep really slowly and it’s nice and smooth.

When it comes to a normal obstacle, it will continue over the obstacle without adding more throttle, which is another reason to make the swap to brushless.

Furitek products are always a good choice. Do they cost a little more? Yes. The smoothness and simplicity to program, along with quality of the product are what you are paying for.

I did previously have an InjoraPurple Viper and ESC in it. The Viper did start to stutter a bit after several uses, but Injora did warranty the motor and sent another. While programming isn’t difficult with Injora, it does require a laptop to program. Phone programming while crawling vs laptop and disconnecting wires to hook to laptop and program, then reconnecting… only you can decide which is best for you.

I also have another TRX4M with the Komodo motor and Lizard Pro ESC. That’s another excellent combination. The Komodo is a small outrunner style motor, the Unity is an enclosed style motor with the ESC made onto it.

If the ESC were to stop working, you might be left having to replace the entire unit, but I’d check with Furitek directly about it. The Unity will use less physical space in the vehicle, as it’s all one piece.

The Komodo and Lizard ESC are two pieces, but they are small. Still, you need a spot for the ESC. I Velcro taped mine to the top of the Injora transmission, which works well for my vehicle.

Each unit has an on and off switch, which I like. If you don’t like the switch, cut the switch off and solder the wires together, and the battery will turn the vehicle on when it’s connected.

Great Motor.

Recently got into mini crawlers and built my first one. Motor with esc combo was a great space saver and has awesome power for has small as it is. Heli direct had it tracking the same day and it arrived perfectly. Might had one to my son's truck.
