Its motor body measures 57.5 mm x 61.5 mm, its external shaft measures 5.98 mm x 36 mm, and the motor weighs 532 grams. Its construction incorporates a 45 mm stator diameter, 25 mm stator thickness, 12 stator arms and 10 stator poles. The winding specification is 8T YY with 1.12 mm motor wire, and the motor constant is 365KV RPM/Volt.
An internal fan works with an external centrifugal fan to provide motor cooling. Continuous electrical ratings are 80 amps and 5106 watts; peak ratings are 160 amps and 10200 watts, each limited to two seconds. The specified LiPo cell range is 12s–16s. Accessories comprise three 6 mm female bullet connectors with heat shrink and one hardware pack containing M4 bolts. Packaged weight is 780 g. The box contents identify the included motor as HK5-4525-535kv, a designation that differs from the HK5-4525-365kv product identity.
