BETAFPV Cube 2-4S F411 Flight Controller with 5.8GHz VTX

The BETAFPV Cube 2-4S flight controller is a lightweight F411 board designed for whoop, micro and toothpick builds running 2-4S batteries. Weighing 1.8 g, it combines a 20×20 mm mounting footprint with an MPU6000 gyro and onboard 5.8 GHz VTX, making it a practical choice for compact FPV drones where space and weight matter.
