Great Video... Getting ready to build my first Quad-Copter, and really looking forward to it.
Just a note on your sound, it really is not that bad. I have been editing video for along time now, and one thing that I like to do is to put a sound track with it when it is edited and then turn the volume down on the plane video. I use Pinnacle Studio video editing software and is very easy to use, and you get a nice product out there.
