Compact brushless power for precise crawling

The Hobbywing QuicRun Fusion SE 1800KV combines a sensored brushless motor and ESC in one compact unit for 1/10 rock crawlers. The integrated design frees up chassis space and simplifies wiring, while Field Oriented Control (FOC) delivers smooth low-speed response and strong crawling torque.

Features

• FOC control for smooth starts and precise low-speed driving.
• Closed-loop speed control adjusts torque as the load changes, helping maintain a steady crawling pace.
• Adjustable active drag brake for controlled descents and holding on slopes.
• Quiet, efficient sine-wave operation.
• IP67-rated waterproof and dustproof design.
• Low-voltage, over-temperature, throttle-signal loss and motor lock-up protection.

What is included

One 1800KV Fusion SE integrated motor and ESC unit, with its wiring, XT60 battery connector and electronic power switch.

Compatibility

Designed for 1/10 rock crawlers using a 540-size motor installation. The motor body measures 36mm in diameter and 58.1mm long, with a 3.175mm output shaft. It supports 2S-3S LiPo or 6-9-cell NiMH batteries and provides an adjustable 6V or 7.4V BEC output.

Setup and programming

The ESC is built into the motor, so a separate speed controller is not required. ESC parameters can be adjusted with a compatible Hobbywing LED program box through the dedicated programming port on the electronic switch. A programming box is purchased separately.

Does this need a separate ESC?

No. The ESC is integrated into the motor for a compact installation with less wiring.

Which batteries can it use?

It supports 2S-3S LiPo and 6-9-cell NiMH batteries, with an XT60 battery connector.

Is this suitable for slow technical crawling?

Yes. FOC control provides smooth low-speed operation, while closed-loop speed control adjusts torque as the load changes.

How are the settings adjusted?

Use a compatible Hobbywing LED program box, sold separately, connected to the programming port on the electronic switch.

What size is the motor?

The motor body is 36mm in diameter and 58.1mm long, with a 3.175mm shaft.
