Hi Henke

I have had to put aside my interest in this subject for almost 8 years for a variety of reasons but I am back, thankfully and I can see there have been some advances is EDF capabilities. That's an interesting turbo prop / fan installation you have posted there. How much thrust does it produce?

My interest in the hobby in general at this point is more of an academic pursuit. What I wish to build would not be accepted by AMA rules and standards without a massive waiver, so in this current climate of government oversight do to the irresponsible piloting of consumer quality "drones" I doubt I will ever see an endorsed flight. That said, the technology I require is probably still a couple of years away and regulations could pile up before then. Who knows, but I'm just babbling now.

My aim in my project is to create an as scale reproduction as possible on as many fundamental levels a 1/5 scale SU-35. This scale approach includes the engines. Since a strictly axial flow low bypass engine is problematic I though a more high bypass design with a centrifugal flow impellerwould offer greater possibilities of success.
