Hummingbird 305 Flight Stack – F722 FC with Built-in ELRS + 80A 4in1 ESC Optimized for 5” to 10” Drones | Up to 8S LiPo Support | Built for Power & Durability Hummingbird 305 Stack combines advanced control with unmatched power. This stack is built for serious freestyle and long-range missions, featuring the Hummingbird 305 Flight Controller with a high-speed F722 MCU, built-in 2.4GHz ExpressLRS Diversity Receiver, and full support for Betaflight & iNAV firmware. Designed with a TCXO oscillator and barometer, it’s ready for precise GPS navigation and auto-return missions. Matched with the Hummingbird 305 4in1 ESC, this power system supports up to 80A continuous for 10 seconds and 100A burst for 3 seconds per channelper channel on 3–8S LiPo, delivering insane performance with robust protection. The ESC features 3oz 6-layer gold-plated PCB with blind vias, AT32F421 MCU + integrated Gate Driver, and 3x massive onboard TVS diodes, eliminating the need for external surge protection. This stack is ideal for 5”, 7”, and even 10” drones, offering maximum reliability, clean wiring, and consistent high-current performance.
