Product overview
The Scorpion A-5524-205kv V2 serves 74"–78" acrobatic airplanes and sport/UAV aircraft, with a stated single-engine sport/UAV aircraft weight range of 30–40kg. Its BLDC architecture combines a 55.0mm-diameter, 24mm-thick stator with 12 stator arms, 14 magnet poles and a 9T/10T Delta winding. Silicon steel stator sheets are 0.2mm thick, while the enamel-coated copper windings use two 0.96mm strands rated above 200C+. For installation planning, the motor body measures 74.0mm x 65.8mm, the external shaft is 10mm, and weight rises from 622g for the motor alone to 655g with prop mount accessories.
The supplied configuration contains the motor, an A-55/65 cross mount, four M4 mounting bolts, three prop bore spacers, three female 6mm connectors, three heat-shrink pieces, three stickers and two M8 nuts. Recommended integration choices are 21x12, 22x10E or 23x8E propellers and a Tribunus III 14-150A ESC SBEC. Continuous ratings are 80A and 3552 Watts; peak ratings reach 105A and 4662 Watts for intermittent full-throttle use lasting 5–60 seconds, depending on application and cooling. The maximum rated LiPo configuration is 12s, with higher cell counts possible when using smaller propellers.
