Quicrun Fusion SE Crawler - 1800KV

HW30404317 is the Hobbywing Fusion SE 1800KV – a smart 2-in-1 brushless motor with a built-in 40A speed controller (ESC), developed specifically for 1/10 crawler cars. The integrated solution saves a lot of space in the chassis, provides ultra-smooth FOC-controlled motor operation and is IP67 waterproof, so you can drive in almost any terrain and weather.

Compact 2-in-1 design – easy installation in 1/10 crawlers
Motor and ESC are built together in one unit, so you don’t have to find space for a separate speed controller and extra wires.
Fits perfectly in most 1/10 rock crawlers and scaler builds:

• Easy to install in all 1/10 crawler cars
• Less cable clutter and better space in the chassis
• XT60 connector pre-installed from the factory – be aware of this in relation to your batteries
• No soldering required: simply connect the receiver cable to your receiver and the power plug to the battery

The motor is 58 mm long and 36 mm in diameter, so it fits most standard motor mounts for 540-size motors.

FOC technology – extreme control and efficiency
Fusion SE uses FOC (Field-Oriented Control), which has been a game changer in crawlers:

• Very smooth and controlled driving – even at ultra-low RPM
• Almost silent operation with plenty of torque
• High efficiency = lower temperatures and longer run time
• Significantly better response and power delivery than traditional brushless systems

The FOC system ensures that the motor delivers power exactly as you request it on the throttle – both for crawling and when you need more punch.

—

Intelligent Torque Output – full control uphill and downhill
The built-in FOC ESC has smart torque management, so the car behaves predictably on both climbs and descents:

• The ESC automatically adjusts the motor’s output and RPM according to your throttle input
• Intelligent Torque Output helps match the motor’s power to load and incline
• Gives you better control on technical sections where grip changes

The result is a crawler that feels more “mechanically locked” to the surface, without sudden jerks or unpredictable behavior.

—

Powerful Drag Brake and hill-hold function
For serious crawling, a strong and adjustable drag brake is crucial. Fusion SE delivers:

• 8 levels of Drag Brake Force (Power)
• 9 levels of Drag Brake Rate (how the brake builds up)
• Up to 2x stronger drag brake than normal brushless setups

This gives you an almost “locked axle” feel when you release the throttle – perfect for steep descents and precise positioning on rocks.

—

Robust and built for hard use
The Hobbywing Fusion SE is designed to withstand daily use and tough runs:

• Silicone rubber seals and tight buttons
• Quality components and hardware for long life
• Designed to withstand impacts, vibrations and dirt from off-road driving

—

IP67 waterproof – ready for all conditions
With an IP67 rating, the Fusion SE is protected against water, dust and dirt:

• Can be used in wet terrain, mud and snow
• Protected against dust and small particles
• Ideal for outdoor crawl sessions all year round

Note: IP67 means water and dust protection under controlled conditions. It is not a guarantee of permanent sealing. Prolonged submersion in water is not recommended, as it may damage the product, and the protection level may decrease over time due to aging.

—

BEC – strong power for servo and electronics
The built-in BEC can supply plenty of power to powerful crawler servos:

• Adjustable BEC voltage: 6.0V or 7.4V
• Continuous BEC current: 4A
• Peak BEC current: 6A

Perfect for high-torque servos, winches and other accessories, without needing an external BEC.

—

Driving modes and programming
Fusion SE gives you flexible driving profiles and fine-tuning:

• Driving modes (via programming box):

- Forward / reverse and brake
- Forward and reverse
- Constant speed forward and reverse (cruise-like control)
- Drag Brake can be set so the car can hold position on hills, etc.

• Programming via:

- SET button on ESC: Not supported
- LED Program Box: Supported
- LCD Program Box: Not supported
- OTA Programmer: Not supported
- Programming port: Independent interface (at the switch position)
