No, it's not. I'm just pointing out the 4 electric motors because they're not directly visible in the video, and their use makes the whole flying thing a bit more plausible.
There's no need for you to position yourself as a gatekeeper for HN comments, either, but you're doing it anyway. Who elected you to quota individual comments? When you went after me, I had left three comments on this entry. There were more than a dozen by the time you said something, and I had made my point and was willing to back out.
If you've identified a noise problem in the signal -- the only possible reason to go directly after another commenter and expect that you're improving HN at all -- how does spamming yet more about the noise problem improve the situation for anybody?
Thanks for reminding me why I don't contribute to HN, by the way. I'll show myself back out.
You can see a pic of said motors here: http://www.humanbirdwings.net/wp-content/uploads/2012/01/Tim...
