Firma 1400Kv Brushless Sensored Crawler Motor

The Spektrum Firma 1400 Kv Sensored Brushless Motor is purpose-built for 1/10 scale rock crawlers, scalers, and trailers. Featuring a precision 4‑pole 8‑magnet rotor, CNC-machined aluminium housing, FOC sensored control, and a 1/8″ hardened steel shaft, it's designed for smooth torque, scale control, and maximum traction.

Features

• Designed for extreme slow-speed, high-torque applications with advanced drag brake control
• CNC-machined aluminium can with insulated high-purity copper windings
• Butterfly 1/8″ (3 mm) hardened alloy steel shaft with polarity protection via magnetic encoder
• 3.5 mm gold-plated bullet motor connectors pre-installed
• Fully waterproof design suited for wet and dusty environments
