About the Motor

Engineered for Speed and Endurance
This 4500Kv 4-pole brushless motor combines high efficiency with rugged construction to deliver both power and longevity. The low-cog sintered rotor and precision ball bearings reduce resistance and improve overall performance. A hardened steel shaft adds durability, while the CNC-machined aluminum housing helps with heat dissipation during high-speed runs. The insulated high-purity copper windings maximize efficiency, ensuring consistent output on both 2S and 3S LiPo setups. Designed as a direct replacement for the Firma Motor/ESC/Receiver Combo, this motor offers plug-and-play convenience with race-winning performance.
