The BeeBrain BLV4 AIO Flight Controller with built-in 2.4GHz ExpressLRS is perfect for the smallest of builds. This all-in-one board combines a flight controller, 12AMP 4-In-1 BLHeli_S ESC, 5.8GHz VTX, and a 2.4GHz ExpressLRS receiver on one 29x29mm board. Amazing performance and features on a part that occupies so little real estate.
