RCINPOWER AOS Supernova 4220 415KV Brushless FPV Drone Motor

The AOS Supernova 4220 415KV is a high-performance brushless motor specifically engineered by Chris Rosser at AOS RC for heavy-lift platforms, large VTOL aircraft, and X-Class FPV drones using 13-inch propellers and larger. Manufactured in collaboration with RCinPower, this motor utilizes 3D transient field modeling and extensive finite element analysis to deliver high torque, rapid throttle response, and thermal stability under sustained heavy loads.
