Firma 780Kv Brushless Motor

The Spektrum Firma 780Kv Brushless Motor (SPMXSM1100) is built for large-scale RC power, delivering smooth, efficient performance on 3–8S LiPo systems. A low-cog 4‑pole, 8‑magnet rotor teams with a CNC‑machined aluminium housing featuring heat‑sinking fins for robust cooling and durability. High‑purity copper windings, precision bearings and a hardened 8 mm output shaft provide reliable torque delivery and long service life. Preinstalled 6.5 mm gold‑plated bullet connectors simplify installation, and the motor is perfectly matched to the Spektrum Firma 160 Smart ESC.
