Firma 4074 2050Kv 4-Pole Brushle (SPMXSM1700)

Firma 4074 2050Kv Brushless Motor is a high-performance drive designed for 1/7 and 1/8-scale RC buggies, truggies, and monster trucks powered by 3S to 6S LiPo packs. It features a low-cog 4-pole, 8-magnet rotor, a CNC-machined aluminum housing, insulated high-purity copper windings, and a hardened 5mm steel output shaft with precision bearings for durable, smooth operation. The motor ships preinstalled with 4mm gold-plated bullet connectors for easy installation and is designed to pair with Firma ESCs for optimized performance.

Designed for 3S–6S LiPo setups, this 2050Kv motor delivers strong torque and reliable power for fast laps and rugged off-road use. The Safe-D Shaft provides a C-clip locking point to prevent pinion gear slip, and the high-efficiency design, along with a 4-pole sintered rotor and precision bearings, ensures long-lasting performance. It’s a capable upgrade for 1/7 and 1/8-scale racers and bashers and pairs well with the Firma 150 Smart ESC to deliver a balanced, high-performance drive train, with secure 4mm gold-plated connectors simplifying installation.
