Spektrum Firma 2100Kv Brushless Sensored Crawler Motor

Key Features

• 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. 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 Spektrum FIRMA 60A Sensored Brushless Smart Crawler ESC is required.
