Paul,

Take a look at this project.

http://sonexlinks.com/builders/pmain/index.htm

The builder is Pat Main, Sonex plans #72.  The engine is a Mid West circa 94
(105 hp).

I was able to contact Mid West (now in Germany), a Ken Huntly
(http://www.midwestengines@avnet.co.uk ) returned an email with the attached data
sheet.  The comes with a redrive, but it isn't a planitary.

No yet word on fuel consumption, TBO, wieght.

Sure would like to see the Moller engine sometime, maybe it'll be ready by
the time I'm ready to install an engine on my project.

Any experiences/thoughts on the Mid West?

Looks cool. Well the BSFC is a bit high I think. Something to do with the
air cooled rotor required blower sucking down HP I suspect. Wankel Gmbh 
claims better BSFC for their similar HP rotaries. I have heard nothing 
bad about this engine but they are not cheap at about 10 or $12K.

Can you print and scan that data sheet? Can't handle .doc files.
