Product overview
The Scorpion HKIV-4035-450KV is a fourth-generation helicopter motor supplied as a propulsion component. Its electromagnetic architecture combines a 40 mm stator diameter, 35 mm stator thickness, 12 stator arms and 10 magnet poles. A 5+6 Turn Delta winding uses single-strand 1.35mm wire, with a motor speed constant of 450KV RPM / Volt. The motor weighs 456 Grams (16.09 oz), giving the installation a defined component mass alongside its electrical requirements.
Installation space must accommodate a 49.5 mm outside diameter and 64 mm body length, together with a 5.98 mm shaft diameter and 102.4 mm overall shaft length. The supplied package contains one motor, three female connectors, three connector covers and four M4 screws. Electrical limits are 12s LiPo, 75 Amps continuous current and 3330 Watts continuous power; the higher 95A and 4218 Watts ratings each apply for 5 seconds. Motor timing is 5deg and drive frequency is 8kH.
