This video https://www.youtube.com/watch?v=wUVvQk7XLd4 if none other vindicates the outline of the geometry of the frame I've pursued (and patented, else attempted to) over the last two years albeit at a larger scale altogether. We may yet use the components listed in the video to compare the thrust available from the overlapped-8 used I our prototype as against a conventional X-8, which I have always suspected of generating rather less.
Won't be anything we get to do however this side of the GoFly challenge...
