Diabolic
This is a photo of the only one I have seen. I found it like this at Joe Nall. The sign claimed that the tail came of 15 seconds into the flight. I did not see how the guy did it but I looked at the construction in the tail and it was not strong by any stretch.
I had been interested until I got a good look at this one. If you get one I would follow FlyHard's advice and keep it slow.
