These flat Sunny Sky V4004 motors are designed for long-flight time multi-rotors, providing enough torque at low RPM and peak efficiency during flight. The motors use Sunnysky's patented design to prevent loosening and ensure stable output power. With original Japanese EZO bearings, they offer quiet and stable flight. The hollow-cutted caps save weight, maximizing thrust-to-weight ratio for extended flight time.
Tested with strict QC protocols, each motor is dynamically balanced to the highest standard. The axial and radial runouts are tested to ensure precise and stable power output. With a controlled performance difference within 3%, these motors are ideal for professional applications.
