A couple of years ago, I had a thread going about a wingless "contraption" built by a friend, which I was a little skeptical about.
It flew quite well and I was a little surprised that it could almost go slow enough to be hovering.
Now he's done a much improved version, which flies super slow or fast and can do quite a few aerobatics.
Has anyone got any ideas on what makes this thing actually fly as well as it does? - I've included a few photos taken about 9 months ago, - haven't seen this guy around much lately, so I didn't get many details of the plane, just the photos.
I do know though that it doesn't "prop hang", ( not much power, - it has a 20 size motor I think).
The first photo is of his original effort.
