Overview

The Firma 2800Kv Sensored brushless motor is a great choice for 1/10 scale crawlers, rock racers, and trailers running on 2S – 3S LiPo power. Featuring a low cog 4-pole 8-magnet rotor design, CNC machined aluminum housing, insulated high purity copper windings, high-quality alloy steel 3.175mm (1/8″) output shaft, and precision bearings for high durability and smooth rotation. Preinstalled with 3.5mm gold plated bullet connectors for easy installation. The

  • Excellent upgrade for 540 brushed motors with the same diameter and mounting pattern (vehicle must accept pinions with a 1/8" mm bore)
  • Perfect for high speed off-road applications such as rock bouncers and rock racers
  • 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
