HobbyWing QuicRun Fusion SE 1800KV, for crawler, 540spec

The HobbyWing QUICRUN Fusion SE 1800KV combines a brushless motor and ESC into a compact, integrated 2-in-1 system built specifically for 1/10 scale rock crawlers. Designed with FOC (Field-Oriented Control) technology, it delivers ultra-smooth low-speed performance, strong torque, and quiet operation even under extreme crawling conditions.

By integrating the ESC directly into the motor housing, wiring is simplified and chassis space is freed up, making it an ideal solution for clean scale builds and tight crawler layouts.

Key Features

Integrated 2-in-1 Design

ESC and motor in one compact unit. Reduces wiring clutter, lowers weight, and simplifies installation.

FOC Driving Mode

Strong low speed torque and smooth startup performance, superior to many sensored brushless systems and even brushed setups.

Quiet & Efficient

Sine wave driving mode reduces heat, improves efficiency, extends runtime, and delivers near silent operation.

IP67 Waterproof

Excellent waterproof and dustproof performance for mud, snow, sand, and water crossings.

Intelligent Torque & Speed Control

Closed loop speed control and intelligent torque output simulate real vehicle cruise control and controlled downhill descent.

Active Drag Brake

Adjustable drag brake force provides strong hill holding capability.

Multiple Protection Systems

• Low voltage protection

• Overheat protection

• Throttle signal loss protection

• Lock-up protection

Easy Programming

Compatible with HobbyWing LED Program Box. Independent programming port integrated into the electronic switch.
