The HGLRC Zeus F728 is a combination of a Zeus F722 mini flight controller and a Zeus 28A ESCs. The stack is especially suitable for 3-4" drones and 5" ultralights.
The flight controller meets all the requirements of a modern board such as an F7 processor, large solder pads, a connector for connecting a DJI FPV or 8M memory for a black box. The ESC uses the BlHeli_S firmware. Its main advantage is a protective TVS diode, current sensor and large solder pads for easier installation.
