Product overview
The Scorpion A-7430-155kv (V2) is an electric propulsion motor for freestyle and UAV airplanes requiring an 80cc-100cc equivalent gas engine. Its construction combines rotor magnets with 0.2mm silicon steel stator sheets and single-strand enamel-coated copper windings rated above 250C+. A 74.0 mm diameter, 30 mm thick stator has 24 arms, paired with 28 magnet poles. The winding specification is 7T 4Y with 1.12mm diameter wire, and the motor speed constant is 155 RPM / Volt.
Airframe integration must accommodate the 86.80mm x 70.4mm motor body, an additional 20.0mm prop spacer and a 10mm external shaft. Weight is 1271.0g for the motor alone or 1367g including prop mount accessories. This is a propulsion component for airplane integration. Optional accessories comprise a 100cc-120cc cross mount, a 100cc-120cc standoff set and an 80V 1880uF capacitor / PDB board with mounts. The recommended controller is the Tribunus II+ 14-200A ESC SBEC, which requires baffling that directs airflow directly to it; a cowl opening alone is insufficient.
Continuous ratings are 110A and 5328 Watts, with peak current of 150A. Peak power is 7500 Watts for intermittent full throttle lasting 5-60 seconds, depending on use case and cooling. Recommended propellers are 28x12 C2E or 28x13 C2E on 12s, and 25x12E or 26x12E on 14s. Aircraft weight ranges are 10kg-22.72kg for acrobatic use and 16.14kg-48.43kg for single-engine sport/UAV use. Excessively long battery cables will damage the ESC and void the warranty; the Scorpion 1880uF Capacitor / PDB Board is recommended for long-cable installations.
