I would like to see Flite test do a show about cyclogyros and attempt to make an rc one. I did not know these existed, but was intrigued when I saw one in this recent article. I have not seen a video that has explained how they work that has been nearly as good as Flite test production quality. Peter Sripol made a magnus effect plane, but that is slightly different in the way that it functions in that the "wings" are only for lift, not propulsion as well. Foamboard with some 3d printed parts should be able to make one.
