Sunnysky V series of motors are specially designed to power long-endurance multirotor aircraft. Design styles of the whole series are high efficiency, stable structure, lightweight, high consistency, etc. These flat Sunny Sky V4004 motors are designed for long-flight time multi-rotors. These motors can produce enough torque at low RPM and work at peak efficiency during flight.

The whole series uses Sunnysky’s patented Stepped and knurled design that not only efficiently prevents motors from getting loose, but also reduces the probability of malfunction and unstable output power. The whole series use original Japanese EZO bearings that provide quiet and stable flight in the air.

With the guarantee of strength, the caps of V motors are highly hollow-cutted to save weight, so that these Sunny Sky V4004 motors can reach maximum thrust-to-weight ratio and gain more flight time.

V series motors are tested with the strictest procedures of SunnySky QC protocols. Each of these motors is dynamically balanced with our highest standard. The axial and radial runouts of each rotor are tested strictly according to its design. The difference in the performance of each motor is controlled within 3% so that these products can provide precise and stable power for professional applications.
