Same body, with a slim painted surface and more weight on nose - 2 cloth pegs. Here are the images of the flights; better to say short jumps up and fast falls, although photo's may cheat. No, it was not flying, except maybe few parts of seconds or a second the most. That was the reason why I persisted in further development of this strange model.
Here are links for videos of flights:
