That is inspiring!
Now 47, he is producing some kind of pedal-powered hang-glider. There are few details on his site, but I have written to him and hope to know more soon. Sounds really interesting. (update - exchanged email this a.m., 17th Feb. Following two pics provided by Rupert himself)
"The mechanism is very simple:
Bevel gears to change thrust direction, a flexi shaft for the supine version and away you go"
Coincidentally, I have been reading about a pedal powered aircraft, the Musfly, that David Cook was working on in 1979, the year I took 'O' levels. Sadly, the project was abandoned, but something Cook says in the book, Flying From My Mind, really struck a chord,
"I was beginning to think that what already existed wasn't necessarily always right and often the way forward is not to be influenced by the knowledge of other people, but to believe in one's own designs"
It seems to me that Sweet-Escott has that attitude too and it really chimes with mine, and I can't wait to see what comes of it. "Ru" tells me there is even a chance that the Nomad, which had push right, go right stearing at the feet, may go back into production.
