About this part

Hobbywing QuicRun Fusion SE FOC 2-in-1 540 Spec Crawler Brushless ESC and Motor System. This innovative 2-in-1 system utilizes a compact integrated ESC giving you one of the most compact and easy to setup motor/ESC systems. Featured FOC technology provides incredible low speed control and the smooth startup needed for rock crawling. This system also uses an IP67 waterproof rating giving you the confidence to tackle any trail condition. Additionally there are several programming options built into the ESC giving you the ability to tailor the driving experience to your preferences. Packed with technology specific for scale trucks and rock crawlers the QuicRun Fusion SE FOC 2-in-1 540 Spec is an excellent addition to your next build.

Features:
  • The integrated design of the ESC and the motor greatly reduces the overall volume and weight, and makes the layout and wiring of car frame simpler and more convenient.
  • The FOC driving mode provides excellent low speed torque and smooth running at extreme low speed, which makes this superior to the common sensored brushless power systems.
  • Thanks to the sine wave driving mode, the whole system has high efficiency, low heat, and effectively extends the runtime. Additionally the motor runs more quietly and smoother.
  • IP67 waterproofing gives this system excellent waterproof and dustproof performance. Under various weather conditions, the whole system can easily deal with environments containing silt, ice, snow, and water.
  • Intelligent torque output and speed closed-loop control, experience the cruise control and steep slope slow descent function.
  • Active drag brake force adjustment, providing super strong parking capacity on slope.
  • Multiple protection functions: battery low voltage protection, overheat protection, throttle lost protection, lock-up protection.
  • Supports LED program box to set ESC parameters (sold separately).
NOTE: To access ESC adjustments the Hobbywing LED programming card (HWA30501003) is required (sold separately).

I have this in a trx4 and I love it. I also have a 1800 kv pro and this one feels more smooth to me. It is about the same speed as the stock motor as far as I can tell. The best part though is the drag brake force. This thing is a beast. The tires slip long before the motor does. I also love the low end speed control. It's a great motor and I'm sure it's the best one you can get for this price. Definitely worth the money.

This my first time I buy Fusion, and I understand why is difficult to beat at this price, even the 1080 have trouble to beat this Fusion. Some youtubers consider don't have modulation, but wrong. Once you install the motor you can see the modulation is pretty torque. I bought the 1200kv, with this I can go 12t Trx4 instead 10t. And before give the rating is was sold again. Amain buy 100 and you will sell again all. Great motor no regrets ?

El sistema FOC es asombroso. Esto la da un realismo total a mi Crawler Vanquish VS4-10 Phoenix

Phil IdellVerified owneron Hobbywing QuicRun Fusion SE FOC 2-in-1 Crawler Brushless ESC & Motor

Works great. Good speed, small footprint, easy install and programming. I picked up a few of these and the pro. Who knows, maybe I will grab up the Axe system and put in my SCX6.

Chef's kiss on this 2n1. If you have a straight axle rig, this is your motor

What reviewers say

Reviewers almost uniformly rate this 2-in-1 FOC motor and ESC system highly, with all seven reviews giving five stars. Owners describe smooth, torquey low-end performance, strong drag braking, and a small footprint that removes the need for a separate ESC and its wiring. Several note speed roughly comparable to a stock motor and easy installation and programming. Reviewers installed it in TRX-4, TF2, RC4WD Blazer, Vanquish and SCX6 crawlers. One review reports a 1200Kv unit allowing a 12-turn motor in a TRX-4 instead of 10-turn, and another notes a dispute over modulation that the reviewer found was not an issue after installation. No significant recurring problems are reported.

  • + Smooth, torquey low-end control
  • + Strong drag braking
  • + Small footprint, no separate ESC
  • + Easy install and programming
  • − Speed roughly similar to stock motor
  • − Modulation criticism from some outside sources
