The HW30A 30A ESC Brushless Motor Speed Controller is a compact and reliable electronic speed controller designed to efficiently drive brushless DC (BLDC) motors in RC aircraft, quadcopters, drones, helicopters, boats, and robotics projects. With a 30A continuous current rating and 40A burst current (up to 10 seconds), it delivers smooth, responsive throttle control while maintaining stable performance under demanding conditions. It supports 2–3S LiPo or 4–10 cell NiMH/NiCd battery packs and features a built-in 5V/2A BEC (Battery Elimination Circuit) to power receivers, servos, or flight controllers without requiring an additional power source.

The ESC includes intelligent protection features such as safe power-on arming, low-voltage cutoff, overheat protection, signal-loss protection, and throttle calibration, ensuring reliable operation and protecting both the battery and motor. Its low-resistance MOSFET design improves efficiency, reduces heat generation, and provides fast throttle response for smooth acceleration and precise motor speed control. The compact and lightweight design makes it ideal for space-constrained RC and DIY electronics projects.
