Firma 800Kv 4-pole Brushless Motor

The Spektrum Firma 800Kv 4-pole Brushless Motor (SPMXSM2600) delivers serious torque and efficiency for large-scale RC applications. Built around a sensorless inrunner design with a low-cog 4-pole rotor, it provides smooth power delivery on 3–8S LiPo while maintaining durability thanks to a CNC machined aluminium housing, high-purity copper windings and precision ball bearings.

A hardened 8mm Safe-D output shaft helps prevent pinion slip, and preinstalled 6.5mm gold-plated bullet connectors simplify installation. With up to 110A continuous current handling and an 87% efficiency rating, this 1/5 scale motor is a robust choice for high-power setups. It is also recommended to be paired with the Spektrum Firma 160A Brushless Smart ESC.
