HOBBYWING QUICRUN Fusion SE 1200KV 2in1 Crawler 1/10 540spec HW30404318

The Hobbywing QuicRun Fusion SE 1200KV is an integrated brushless motor and ESC system for 1/10 RC rock crawlers, suited to trail drivers wanting smooth low-speed control, simplified wiring and strong hill-holding performance.

This compact 2-in-1 crawler power system combines the motor and ESC inside a 540-size style unit, reducing wiring clutter and saving chassis space. FOC control, sine wave drive, active drag brake adjustment and IP67-rated protection make it a practical upgrade for technical crawling, scale trail driving and steep terrain control.

Features

• Integrated 2-In-1 Design: Combines the brushless motor and ESC into one compact crawler power system
• 1200KV Crawler Tune: Lower KV option suits controlled crawling, technical trails and torque-focused setups
• FOC Control Technology: Field Oriented Control supports smooth low-speed throttle response and intelligent torque output
• Quiet Sine Wave Drive: Helps reduce motor noise while improving smoothness and efficiency
• Active Drag Brake: Adjustable drag brake helps hold the vehicle on climbs and descents
• Closed-Loop Speed Control: Helps maintain controlled wheel speed when climbing or descending under load
• IP67 Protection: Designed for normal wet, muddy, sandy, snowy and dusty crawler conditions
• Compact 58.1mm Length: Shorter size helps fit more 1/10 crawler chassis than larger integrated systems
• Adjustable BEC Output: Switchable 6V or 7.4V output supports compatible standard and high-voltage servos
• LED Program Box Compatible: ESC parameters can be adjusted using a compatible Hobbywing LED Program Box, sold separately
• Multiple Protection Functions: Includes low-voltage, overheat, throttle signal loss and motor lock-up protection
