NewBeeDrone Hummingbird 305 F722 ELRS 80A 4-in-1 30x30 Flight Stack

The NewBeeDrone Hummingbird 305 is a 30.5x30.5mm flight stack engineered for heavy 5-inch to 10-inch freestyle and long-range drones. It combines an F722 flight controller featuring an integrated 2.4GHz ExpressLRS diversity receiver with a high-capacity 80A AM32 4-in-1 ESC supporting 3-8S LiPo power.

Key features

• Built-in 2.4GHz ELRS diversity receiver with a TCXO oscillator, low-noise amplifier (LNA), and dual U.FL antennas for a clean build without external receiver wiring.

• High-current 4-in-1 AM32 ESC rated for 80A continuous output (for 10 seconds) and 100A bursts per channel, built on a 3oz, 6-layer gold-plated PCB.

• Three onboard TVS diodes absorb up to 1.5kW of peak power, preventing voltage spike damage without needing an external protector.

• Factory-applied nano-coating on both the flight controller and ESC for moisture and debris resistance.

• Dedicated 10V 2A and dual 5V 2A BEC outputs provide direct plug-and-play power for DJI O3/O4, Walksnail, and HDZero digital video systems.

• MicroSD card slot supports up to 32GB FAT32 cards for extensive Blackbox data logging.

Before installing, verify your frame supports a standard 30.5x30.5mm mounting pattern and has adequate vertical clearance for the complete stack. The set includes a 1000µF capacitor, an XT60 pigtail with 14AWG wire, and full wiring harnesses for digital and analog video systems. For heavy 7-inch or 10-inch builds running high-voltage 6-8S packs, carefully solder the included capacitor to the ESC's dedicated corner pads to absorb extreme regenerative voltage spikes.
