In this video series, I will teach you how to wire up ANY flight controller without reference to a diagram or manual. You'll know how to power the board and connect accessories like camera, vTX, and receiver. Quadcopter flight controllers seem complicated at first glance, but they all do pretty much the same thing. Once you understand this, wiring them up is easy.
