Hummingbird V4 ELRS 2.4G AIO Flight Controller

Let's be honest. Your current whoop is probably suffering from the holy trinity of problems: a dodgy RC link, a VTX that cooks itself on the starting grid, and tragic voltage sag. The Hummingbird V4 AIO is the cure. It combines a rock-solid SPI ELRS 2.4G receiver with a clever 400mW SmartMax VTX and a proper solid-pin power connector, creating the most potent 1S brain you can cram into a 65mm frame.

Why You Want It

Because this isn't just an upgrade; it's practically cheating. The SmartMax VTX stays cool while you're disarmed, then intelligently ramps up to 400mW the moment you arm, giving you incredible penetration without melting your canopy. The 12A Bluejay ESCs and BMI270 gyro provide that buttery-smooth, locked-in feel that stock whoops can only dream of. It's the unfair advantage you need to dominate your local whoop race or just fly with impunity around the house while it's chucking it down outside.
