Product overview
The Scorpion HKIII-5040-530kv (8mm 34mm) is a helicopter motor engineered for high-speed racing applications. Its physical architecture combines a 50 mm stator diameter and 40 mm stator thickness with 12 stator arms and 10 magnet poles. The winding uses a 4+3 Turn YY arrangement and 2-Strand 1.4mm wire. With a speed constant of 530 RPM / Volt, the motor is described for use on 14s power, while its maximum LiPo cell specification is 16s.
For installation planning, the motor has a 62.1 mm outside diameter, 74.7 mm body length and 108.7 mm overall shaft length, with a 7.98 mm shaft diameter. Motor weight is 839 Grams; weight including packaging is 1500g. Continuous limits are 200 Amps and 11840 Watts, while the 250A and 14800 Watts peak limits each apply for 2 seconds. The electrical integration specifications also include 5deg motor timing, an 8kHz drive frequency and 0.006 Ohms motor resistance.
