Built for Micro & Toothpick Builds
The 30A 4-in-1 is the smallest in the BX lineup, designed for 2–4 inch toothpick, micro quad, and lightweight cinewhoop frames where every gram counts. At 7g and a 20×20mm/M3 mounting pattern, it drops directly into micro stacks without adding unnecessary weight.
120MHz Processor with Bidirectional DSHOT
Powered by the AT32F421 running at 120MHz, this ESC supports bidirectional DSHOT300 and DSHOT600 — enabling Betaflight's RPM-based filtering for dramatically lower motor noise and smoother flight feel. The high clock speed ensures zero lag between stick input and motor response.
AM32 Firmware with Web Tuning
Running open-source AM32 firmware, the ESC offers a user-friendly web-based tuning interface — adjust motor timing, PWM frequency, and startup power without installing desktop software. Ready to fly out of the box with default settings tuned for micro builds.
Clean Power Delivery
Equipped with a 220µF low-ESR capacitor and 14AWG power leads with an Amass XT30 plug, the 30A handles 3-6S LiPo with stable voltage under load. The 6Pin+8Pin SH1.0 flight controller connector ensures a secure, low-resistance link to your FC.
Full Protection Suite
Built-in over-temperature, low-voltage, and signal-loss protection keep your micro drone safe during aggressive freestyle or proximity flying. The compact 6.5mm-thick PCB fits inside even the tightest micro canopies.
