Hi Folks,

I'm a Europa builder, and new to the list, and look forward to learning
more about these very unique engines. After some research, I figure (as
I assume most listers have) that the most reliable auto-conversion is
the rotary.

Anyway, here's my question; does anyone here have any experience with a
single-rotor mazda?

Also, I was wondering:

- what the all-up wet weight might be with redrive
- how much horsepower (~100hp?)
- what the fuel burn would be at 75%
- if there were problems with rough-running with only the one rotor, as
there are less pulses per rotation than an normal 4-banger.
- would adding a turbo increase efficiency (in addition to the
normalizing)?
- if leaned out as far as possible, would the efficiency be comparable
to a rotax 4-banger?

I could only find one single rotor example on the web, built by Yaw
power products (apparently no longer in the aviation biz) for Gerry Hess
up here in Canada somewhere. Could anyone point me to his email address?

Apologies if these question have already been answered.... is there a
searchable archive for this list somewhere?

Any info/experience would be greatly appreciated.

Cheers and many thanks,
Pete Zutrauen
