FIRMA 1200Kv 1/6 BL Sensored Crawler Motor

The Spektrum FIRMA 1200Kv 1/6 BL Sensored Crawler Motor (SPMXSM3100) is built for giant-scale crawling where smooth control, torque and durability are essential. Its large 5684 can and sensored design help deliver low-cog startup and precise throttle response across challenging terrain.

Overview

Ideal for giant scale crawlers, rock racers and trailers running on 2S–4S LiPo power, this motor features a low-cog 4-pole, 8-magnet rotor, CNC-machined aluminium housing, insulated high-purity copper windings, a high-quality alloy steel 5mm output shaft and precision bearings for smooth, long-lasting performance. It arrives with 3.5mm gold-plated bullet connectors for straightforward installation, plus a waterproof sensor lead with a locking plug and gasket. A built-in magnetic encoder provides polarity protection by maintaining phase signal consistency — simply match wire colour to your ESC connectors.
