The XXD HW30A 30A Brushless ESC (Electronic Speed Controller) is a high-performance and lightweight motor controller engineered for brushless DC motors used in RC airplanes, quadcopters, helicopters, and multi-rotor drones. With a robust 30A constant current rating and a short burst capacity of up to 40A (under 10 seconds), this ESC delivers smooth and precise speed control for a wide variety of brushless motors.
Powered by 2–4 cell LiPo batteries or 5–12 cell NiMH/NiCd packs (input range 5.6V–16.8V), the HW30A includes a built-in 2A linear BEC (Battery Eliminator Circuit) that supplies regulated power to your receiver and servos, eliminating the need for a separate battery. The ESC is optimized for smooth, linear throttle response, providing pilots with accurate motor control during flight maneuvers.
Built with low-resistance MOSFETs, the HW30A minimizes heat loss and runs significantly cooler than many competing ESCs of the same rating. It supports high-RPM motors and uses smaller MOSFETs to reduce overall weight without sacrificing performance — a critical advantage in aerial RC applications where every gram matters.
The ESC is fully programmable either through your transmitter or via an optional programming card, allowing you to customize parameters such as brake mode, throttle range, low-voltage cutoff, motor timing, and start-up behavior. Built-in safety features such as auto signal loss shutdown, safe power-arming, and auto motor cutoff with reset ensure reliable and safe operation in all flying conditions.
