NewBeeDrone Hummingbird V4 AIO Flight Controller ELRS 2.4G with 25-400mW VTX

The Hummingbird V4 AIO is a highly integrated flight controller tailored for ultralight micro whoops and toothpick builds. Consolidating the flight controller, brushless ESCs, a 2.4GHz ExpressLRS receiver, and an adjustable analog VTX onto a single board, this AIO eliminates complex wiring and drastically reduces total build weight.

Key features

• Integrated 2.4GHz ELRS receiver ensures high-refresh-rate, low-latency control without requiring a separate external RX board.

• Built-in 5.8GHz analog VTX switches from 25mW up to 400mW, significantly improving video penetration through walls and dense indoor environments.

• Consolidated components minimise solder joints, saving critical grams on micro builds where every fraction of a gram affects flight times.
