Product overview
The Scorpion HK5-4035-535kv is a BLDC motor intended for 600 to lightweight 700 size helicopters using a 12s LiPo battery, with additional applications extending to the stated power envelope. Its architecture combines an internal fan with an external centrifugal fan for motor cooling. The stator has 12 arms and 10 poles, with a 5T / 6T Delta winding and 1.35mm motor wire. This is a propulsion component supplied with connection accessories and hardware.
Installation space must accommodate a 49.5mm × 67.1mm motor body and a 5.98mm × 38mm external shaft; motor weight is 474.8 grams. Electrical integration must account for 96 amps and 4264 watts continuously, while the 160-amp and 8200-watt peaks are limited to two seconds. The specified maximum battery configuration is 12s, with higher cell counts possible through appropriate gear ratio adjustment. The box includes one motor, three female 4mm connectors, three heat-shrink pieces and one hardware/accessory pack.
