Spektrum SPMXSM3002 Firma 2800KV Sensored Brushless Crawler Motor 

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 4mm gold plated bullet connectors for easy installation.

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 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. When installing simply match wire color to esc connectors
• 4mm gold plated bullet connectors
• Waterproof sensor wire with locking plug and gasket
• High-quality construction with precision ball bearings and hardened steel 1/8" shaft
