OK Graham,

I got it and lift my hands. I feel I am a poor victim of "One Blade 
Awesome Myth Aspect (OBAMA)".

Think about the one blade for a moment. It produces thrust one side of 
the airplane only, left, top, right then bottom. And that doesn't 
include the asymmetric effect of angle of attack.The airframe will 
oscillate in a corkscrew fashion, what a horrible prospect  I can almost 
feel my teeth rattling at the thought of it!

2 stroke diesel? Now that is a good idea, most efficient form of piston 
engine.

Not true Raimo, it is impossible to balance out the assymetric thrust. 
Vibration will be awful, so no laminar flow.

Well Graham - Germans have done many "impossible" things during 
centuries...
I have seen a film about this construction (but maybe it was shit who 
knows!).
Please remember, they built also the first ever diesel aircraft (Junkers 
Jumo?) during -30s.
That should have been also "impossible"...
