Thanks a lot simflyer, As we have grey weather, I think I can manage some time to do researches...Claude,
I think that Victory and maybe also Stealth stil exist and on Yahoo forums could be found contacts.
Here in Czech was B10 wing spar recalculated to meet our strenght limits and also 2seater was built.
Drawings could be found by people around. I had contacts cca on 5 MW here and maybe one is for cheap sale.
U2 wing could be adapted to use on trike, as B10 is.
Maybe is real to organize some flywings fly in - probably in Germany.
