Hobbywing QuicRun Fusion FOC System (2-in-1) – 1200KV Brushless Motor with Built-in ESC

The Hobbywing QuicRun Fusion FOC combines a high-performance brushless motor and ESC into a single compact unit, making it one of the cleanest and most efficient solutions for scale trucks and rock crawlers. With Field-Oriented Control (FOC) technology, intelligent torque output, and IP67 waterproofing, it delivers smooth, silent, and powerful performance in any terrain.

Key Features

• Integrated 2-in-1 Design – ESC is built directly into the motor, reducing space usage and simplifying wiring. The unit is the size of a standard 550 motor and weighs just 210g.

• FOC Technology – Field-Oriented Control ensures super-smooth startup, high torque at low speeds, and virtually silent operation.

• Intelligent Torque & Closed-Loop Speed Control – Maintains RPM and torque uphill, downhill, or under load, ensuring consistent performance.

• Waterproof & Dustproof (IP67 Rated) – Built for all-weather use in mud, sand, snow, or water.

• Long Battery Life – High efficiency and reduced heat improve runtime compared to traditional systems.

• Professional Drag Brake System – 8 levels of brake force and 9 levels of brake rate adjustment for superior hill-holding power.

• Advanced Electronic Switch – Sealed, dustproof, and impact-resistant for long-term durability.
