Hummingbird 200 ESC RaceSpec 80A 3-6S AM32 20x20

An ESC (Electronic Speed Controller) acts as the power-management bridge between your flight controller and your motors, translating low-voltage signals into high-current pulses to precisely regulate motor speed. Modern FPV builds predominantly use 4-in-1 ESCs, which integrate control for all four motors onto a single board to save weight and simplify wiring. They are rated by Amperage (A) to match motor power draw and Voltage (S) for battery compatibility, utilizing fast digital protocols like DShot to provide the instantaneous throttle response required for racing and freestyle acrobatics.
