Product overview
The Scorpion HKIV-4035-520kv is a helicopter propulsion motor with a 12-arm stator, 10 magnet poles and single-strand winding. Its stator measures 40 mm in diameter and 35 mm in thickness, with a 5+6 2Y winding and 1.35mm wire. Mechanical integration must accommodate a 49.5 mm outside diameter, 64 mm body length and 5.98 mm shaft diameter. Overall shaft length is 102.4 mm, and motor weight is 456 Grams (16.09 oz).
Electrical integration is defined by a 520KV RPM / Volt rating, a maximum 12s LiPo configuration, 5deg motor timing and 8kHz drive frequency. Continuous limits are 84 Amps and 3729 Watts; the 4617 Watts peak rating is limited to five seconds. The supplied configuration lists a motor, three female connectors, three connector covers and four M4 screws. However, the included motor is designated HKIV-4035-500KV, differing from the product’s HKIV-4035-520kv identity. Weight including packaging is 882g.
