Firma 1400kv BL Sensored Crawler Motor

The Firma 1400Kv sensored crawler motor is a high-performance brushless powerplant built for 1/10-scale crawlers, rock racers, and trailers powered by 2S–3S LiPo packs. It features a low-cog, four-pole, eight-magnet rotor and a CNC-machined aluminum housing for durability and smooth rotation. Preinstalled with 3.5mm gold-plated bullet connectors, this motor is a solid upgrade from 540 brushed motors with the same diameter and mounting pattern, provided the vehicle can accept pinions with a 1/8-inch bore.

Inside, insulated high-purity copper windings pair with a hardened steel 1/8-inch (3.175 mm) output shaft and precision bearings for lasting durability and reliable torque at low speed. A waterproof sensor wire with a locking plug and gasket protects the sensor connection, while an internal magnetic encoder provides polarity protection and consistent three-phase signals aligned to rotor position. For best results, pair with a Spektrum FIRMA 60A sensored ESC; installation simply requires matching wire colors to the ESC connectors.
