As someone has pointed out elsewhere, you can see in one of their other videos that they have major inconsistencies in the videos that they post. For instance, in this picture, http://i.imgur.com/3Fgct.jpg you can see that there is no black square above the "S" logo. Then, the camera points downward, then upward again, and there is a black square above the "S" logo.

This video is very fake.

That's the most annoying inconsistency for me. I think that could be a patch to the wing applied after they managed to pull out the cloth from the spar (if you look at the blog a bit, there are some posts showing that issue). I think the shitty cut around 1:20ish could be them looking down during a screwed launch attempt, and splicing back in after adding the patch. You'll notice in the following video the patch is there from the start.

There is a Dutch news clipping from about a week after video 13 that shows the dude without the patch, which is puzzling. Again, easily explained as using an old photo from before 13, but still.

I also expected to see more up-down, up-down movement from the on-board video (with respect to ground) to coincide with the power strokes.
