In my first point, it wasn't clear that I should go to "First Flight" for Erle-Copter. Since I have a PXFmini, I looked just under that section. For new builders, it is best to make it a simple 1..2...3.. build, and not require us to figure out to look all over the place.
But... despite updating the software, unfortunately I still cannot get the FC to work. When following directions, after connecting the power, now all FC LEDs come on, then a sound comes, then it shows the green light on and the red light flashing.
