RCINPOWER AOS Supernova 4220 515KV Brushless FPV Drone Motor

The RCINPOWER AOS Supernova 4220 515KV is a high-power brushless motor designed by Chris Rosser at AOS RC specifically for heavy-lift platforms, large-scale cinematic rigs, and X-Class FPV drones running 13-inch and larger propellers. Manufactured in partnership with RCinPower, this high-KV variant utilizes advanced 3D transient field modeling and magnetic finite element simulations to maximize flux capacity, delivering massive torque, immediate throttle responsiveness, and sustained thermal performance.
