Firma 1900Kv Brushless Motor (SPMXSM1600)

Firma 1900Kv Brushless Motor is a high-performance powerplant designed for 1/8-scale RC cars, including buggies, truggies, and monster trucks. It runs on 3S to 6S LiPo packs, delivering strong acceleration and reliable top-end speed for demanding off-road use.

Core to its performance is a low-cog, 4-pole, 8-magnet rotor housed in a CNC-machined aluminum shell for durability and smooth operation. Insulated high-purity copper windings, a robust 4mm output shaft with a hardened 5mm steel shaft, and precision bearings help ensure efficient, long-lasting performance. A Safe-D Shaft design provides a C-clip locking point to prevent pinion gear slip, and the motor ships with preinstalled 4mm gold-plated bullet connectors for easy installation. It is designed to pair with the Firma 130 Smart ESC, offering a strong upgrade for 1/8-scale racers and bashers using 3S to 6S LiPo power.
