The HGLRC Zeus is a 20mm Betaflight F4 flight controller with built-in 15 amp BLHeli_S ESCs. It's perfect for micro builds such as 3" or 2" brushless quadcopters, where it's important to save weight and space.
I've invited my friend Xavier, who specializes in micro quadcopters, to join me for this build. He's going to do the build and I'm going to make "helpful suggestions". I think you guys are really going to enjoy this format.
