Great video, but are you sure that that is the female end? The connection to your battery was female. I like flux core solder as well. The rest was pretty good, informational, and would help anyone. Your next video should show the basics for setting up a control board if you are going multi rotor (that sounded odd, going multi rotor). Or it could show the importance of having everything correct (CG connections, prop on right way, etc. ) Great Video.
