Overview
The Hobbywing QUICRUN Fusion SE is an RC ESC+motor 2-in-1 FOC system for 1/10th rock crawler use, combining a 40A brushless sensored ESC and a 540-size motor in a single integrated unit to reduce wiring and save space.
Key Features
- Integrated ESC and motor design to reduce overall volume/weight and simplify chassis layout and wiring
- FOC (Field-Oriented Control) with sine-wave drive for smooth extreme low-speed control, strong low-speed torque, and quiet operation
- Efficient operation with low operating temperatures
- Smart torque output and speed closed-loop control for improved control on climbs and descents
- Drag brake tuning: 8 levels of drag brake force (Power) and 9 levels of drag brake rate adjustment; drag brakes can be 2 times stronger than comparable systems
- IP67 waterproof and dustproof protection (waterproof protection grade IP67)
- Multiple protections: battery low voltage protection, overheat protection, throttle lost protection, lock-up protection
- ESC parameter setup via LED Program Box; independent programming interface integrated on the electronic switch
- Designed for durability with silicon rubber gaskets, electronic buttons, and quality hardware
Note on IP67: The IP67 protection level is splash-resistant, water-resistant and dust-resistant under normal use, and is tested under controlled laboratory conditions to GB/T 4208-2017 / IEC 60529 IP67 level. Splash, water and dust resistance are not permanently effective, and the level of protection may decline due to aging. Do not soak for a long time to avoid damaging the product.

Details

The Hobbywing QUICRUN Fusion SE 2-in-1 FOC system keeps the ESC integrated into the motor can for a cleaner crawler install and simpler wiring.

The QUICRUN Fusion SE combines the ESC and motor in a compact 58mm integrated design to help save space in 1/10 crawler builds.

The Hobbywing QUICRUN Fusion SE combines the motor and ESC into one compact, pre-wired unit for a cleaner 1/10 crawler install.

The Hobbywing QUICRUN Fusion SE 2-in-1 ESC and motor setup is described as offering smart torque output with closed-loop control for climbs and descents.

U-matched hill holding with 8 levels of drag brake force and 9 levels of drag brake rate adjustment helps fine-tune control on steep crawler descents.

The QUICRUN Fusion SE integrates the ESC into the motor and includes an XT60 battery lead plus a wired on/off switch for clean crawler installs.

The Hobbywing QUICRUN Fusion SE 2-in-1 motor and ESC is rated IP67 for waterproof and dustproof protection in crawler builds.
