NewBeeDrone Hummingbird V4 BNF Whoop ELRS 2.4G SmartMax 400mW VTX

The Hummingbird V4 is a 65 mm, 1S brushless tiny whoop that weighs just 19.5 g without a battery. It comes bind-and-fly on the Hummingbird V4 AIO board with an SPI ELRS 2.4 GHz receiver and a SmartMax VTX, making it a light, quiet indoor flyer for beginners and a sharp whoop-racing machine for experienced pilots.

Key features

• Hummingbird V4 AIO: STM32F411, BMI270 gyro, 12A BLHeli_S ESCs flashed with Bluejay 0.19.2 at 48 kHz, NBD7456 OSD compatible with Betaflight
• SmartMax VTX: 25 mW for racing, 100 mW, or temperature-managed output up to 400 mW through the BeeTX 5.8 GHz antenna
• SPI ELRS 3.x receiver; radios on ELRS older than 3.0 need updating, as Betaflight 4.5 no longer supports them
• Hummingbird 0702 30000KV motors on a polypropylene Cockroach V3 65 mm frame with Azi 31 mm tri-blade props
• BeeEye camera under a Goober V2 canopy with a 3D-printed camera adapter; canopy and prop colours are random
