I'm not arguing either, and if it sounded like I was I apologize. Like I said, I can't say you're wrong since I don't know the answer... you may in fact be right. It just doesn't look or feel like the right explanation to me. Watching the video again I kind of see the tail thing you're referencing but it's really hard to watch the controls on the radio and the heli at the same time. Too bad Bill Nye doesn't hang out in the forums.
