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 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.
- 4mm gold plated bullet connectors
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.
