Hummingbird 305 4in1 ESC 80A 3-8S AM32 30x30 Built for Durability & Reliability

The Hummingbird 305 4in1 ESC 80A 3–8S AM32 30x30 is engineered for pilots who demand uncompromising power, durability, and clean design in high-performance FPV drones. Designed to handle up to 80A continuous and 100A burst per channel, this ESC delivers reliable current output for even the most demanding builds from 5-inch freestyle drones to 10-inch long-range platforms.

Featuring a 6-layer, 3oz copper PCB with blind via gold plating, the Hummingbird 305 4in1 ESC maximizes electrical conductivity and thermal dissipation. The board integrates three massive onboard TVS diodes, providing surge protection rated for over 1.5kW peak power—eliminating the need for external TVS components.

Powered by the AT32F421 MCU with a built-in gate driver, this ESC runs AM32 firmware for ultra-smooth throttle response and modern configurability. The corner-mounted capacitor pads make it easy to add extra filtering for large drone builds like 7” or 10”, without messy wiring.

If you’re building a heavy-duty, reliable FPV system with up to 8S LiPo support, the Hummingbird 305 4in1 ESC is the bulletproof power system you need.
