2in1 Brushless Motor with ESC for Rockcrawler. The 2in1 motor and controller combine strong performance with high torque, even at low speeds. It is waterproof and dustproof. The idle speed is 1800 kV, and the maximum current is 40 A. The operating voltage ranges from 7.2 to 12.6 V (2-3S LiPo or 6-9 cells NiMH). The BEC has a power output of 4 A at 6 V / 7.4 V (adjustable).

The SE edition of the regular Quicrun Fusion features numerous enhancements and optimizations made to this special motor/controller combo to maximize the driving experience. Visually, it stands out with an appealing design that is atypical for a Fusion combo.

The Quicrun Fusion SE is compact and has the size of a typical 550 motor, weighing only 201 g, making the combination of motor and controller nearly imperceptible. Thanks to the intelligent torque and speed control, a crawler can easily adapt to any situation. This combo is supported by an excellent waterproof and dustproof casing, ensuring that the fun knows no bounds. Even the electronic switch is appropriately protected.

The technology used is called FOC (Field-Oriented Control), which provides an excellent control feel. The sinusoidal motor drive keeps the controller and motor cooler, resulting in a silky smooth and quiet motor operation.
