Well, I stand corrected. I had some more time so I went and looked around some more and I will admit it can do more than I thought.
Being able to climb is what impresses me, with that you are flying. Before that it is just extending a glide. I wonder how he carries fuel? Compressed or just in tanks?
Those banked turns he did are pretty cool, I could see something like this being a big hit at airshows and other stuff like that.
