Includes: (1) Ezrun MAX 4278 SD Motor (2250kv) (1) Manual Features: EzRun MAX 4200 Series G2R Motors have excellent compatibility with the Hobbywing EZRUN MAX8 G2S ESC. The ESC can automatically recognize this motor, creating a fully sensored power system that offers improved control performance and a refined control feel, while also enabling motor overheat protection. The rotor features four high-strength, high-temperature-resistant sintered Nd-Fe-B magnets with widened magnetic tiles, delivering exceptional torque, explosive power, and stable output. An independent magnetic ring ensures that the Hall sensor consistently outputs a pure rotor position signal, effectively avoiding sensor signal interference and enabling stable operation in sensor mode. With high output efficiency, this motor reduces temperature and delivers more power under the same load. Its CNC-machined aluminum housing, high-purity copper windings, advanced rotor structure, 0.2mm silicon steel laminations, high-quality stainless steel output shaft, and high-precision bearings enhance durability and smoothness. The innovative new sensor interface and rubber-covered bearings provide superior waterproofing and dustproofing compared to traditional sensored motors.
