Has anyone worked with the rotary and a ducted fan? I have done a bit
with RC models, with acceptable performance.

So with the Sachs rotary, adding oil cooling to the engine should
help with better temps and lubrication. Still limited with 5000 to
6000 rpms, I was thinking of direct drive ducted fan instead of a
PSRU and prop.

Anyone have any experience with this approach, or pro's and con's?

Perry Mick. Fooled with it for about ten years. Finally gave up and
put a gear box on it and went 20 or 30 MPH faster on the same fuel burn.

What is the application and required speed range?
  George Wright

George was instrumental in writing a book on ducted fans as I recall.
What was the title and where can someone buy it George?
