ESC 30A Brushless Speed Controller

30A ESC Brushless Speed Controller delivers rock-solid 30 A continuous (40 A burst) power for RC airplanes, multirotors, helicopters, and small boats or cars. A built-in 5 V/2 A BEC powers your receiver and servos, so there’s no need for a separate pack. Pre-soldered Deans-compatible T-plug plus 3 × 3.5 mm motor bullets get you airborne fast.
