I followed the development of the Alekto (TT62) for a while but then it seems the company shut its doors:
From Wikipedia: "Die HPA hat im Juli 2006 Insolvenz angemeldet".
I don't really speak or read German but "insolvenz" doesn't sound too great...
Unfortunately the founder and leading man of the company died before the prototype took to the sky, and if I recall correctly the performance and behaviour of the original design, with embedded Thielerts and props on pylons, was so flawed that they decided to scrap it and redraw it - like a modern PA31! A real shame.
I haven't seen anything about it in years.
