I have some imagery from an early 1990s edition of Jane's All the World's Aircraft which detail the Sadleir 'rotor-in-wing' VTOL designs. They include some nice looking CGI models of various sized aircraft and a sub-scale flying model. Which basically fills the guy's backyard. Of course at the moment my office is being remodeled and they are in a box somewhere...I think for a while there Sadleir was pretty serious but just lacked the venture capital to leave the backyard and takeoff. That and the difficulty of getting a lot of vertical lift out of a ducted fan limited in size to the centre section of a compound wing. But they weren't an investment scam like some pusedo aerospace companies we could all mention...
