Description
Firma 1100Kv four-pole brushless motor with an 8mm shaft is a high-efficiency power unit designed for Arrma Roller kits and 1/5-scale bashers and monster trucks running on 3-8S LiPo packs.
Built with a CNC-machined aluminum housing, insulated high-purity copper windings, and a hardened steel 8mm output shaft, it delivers reliable, smooth performance. It comes preinstalled with 6.5mm gold-plated bullet connectors for easy installation and is designed to pair with the Firma 160 Smart ESC for a clean, matched setup. The Safe-D Shaft provides a c-clip locking point to prevent pinion gear slip, helping keep power transfer secure during aggressive driving.
