That's really cool. I wonder how they got lateral control? There are quite a few videos on this and using a Spektrum radio to boot :)

The prototype craft flies only in circles, but by varying the wing pitch, Ulrich found he could vary the radius of those circles. He could change direction with tight turns, then fly in "straight" lines that are actually the arcs of very wide circles.

Yeah, I noticed it. We should post this on Horizon's Facebook page. Jim and Gary would get a kick out of it.

I took the liberty and posted the link on their Facebook page. They went ahead and reposted it.
