Excellent upgrade for 540 brushed motors with the same diameter and mounting pattern (vehicle must accept pinions with a 1/8" mm bore)

Perfect balance of speed and torque, great for trail and scale crawling applications

High-quality 4-pole sintered rotor

Polarity protection - magnetic encoder inside the motor guarantees consistency between three phases’ signals and always outputs precise signals indicated by rotor position.

3.5mm Gold Plated Bullet Connectors

Overview

The Firma 2100Kv Sensored brushless motor is a great choice for 1/10 scale crawlers, rock racers, and trailers running on 2S – 3S LiPo power.
