Every new version of Scorpion Motors improves upon the previous versions, and now we are pleased to announce the release of the fourth generation HKIV-40 series motors. With the same motor design and materials of our World Championship Winning HKII-45 series, and single strand winding technique on this size of motor, it has better efficiency and power conversion than HKIII-40 series.
Additionally, the HKIV-40 series motors have an entirely new EM field design, which improves the compatibility with various speed controllers available on the market. This new design motor will deliver even more power to your helicopter, with increased efficiency!
