30A Brushless ESC Electronic Speed Controller with BEC

Overview

The 30A Brushless Electronic Speed Controller (ESC) provides smooth, linear, and dependable throttle modulation for multi-cell brushless motors. Optimized for small to mid-sized fixed-wing RC airplanes, helicopters, quadcopters, and autonomous DIY robotics projects, this lightweight speed controller serves as the primary gateway between your battery source and your flight hardware. Its optimized firmware ensures low-latency timing synchronization, delivering crisp throttle execution across all RPM bands.

Built-In Battery Eliminator Circuit (BEC)

This controller features an integrated internal Battery Eliminator Circuit (BEC). The BEC safely drops down the high voltage from your primary lithium flight battery to provide a regulated 5V power feed down the standard 3-pin servo lead. This feature removes the need to carry a heavy secondary battery, providing clean current to power your flight controllers, radio receivers, and control surfaces.

Pre-Wired Plug-and-Play Convenience

Designed to get you in the air quickly, this ESC features high-flexibility silicone power and signal wires. The primary power input comes pre-soldered with a rugged, high-current T-plug (Deans-style) connector to easily link up to your power supply. The output end features three insulated female bullet connectors, making it simple to connect your brushless motor leads without needing a soldering iron.
