That thing looks and sounds great Craig! I'd love to keep up with your progress.
I hear rotary engines are more efficient since the parts move continuously instead
of stopping and reversing direction. How heavy are we talking? And is this
an auto conversion? Fixed pitch or constant speed? Sorry I'm berating you
with questions, but you've now tweaked my interest, and I can't stop thinking
of the possibilities!

It's not better efficiency, but reliability, fewer moving parts, no valves, significantly
higher TBO. BSFC is slightly higher by about 5%, but you can burn auto-gas,
big savings.

With lightweight aluminum end housings, I'm figuring installed FWF of 275lbs. That's
including rad, cooling and accessories.

Yes.
[/quote]Fixed pitch or constant speed?[/quote]
One can go either route, but my plan is to go with a vari-prop constant speed unit
to maximize performance and efficiency.
Of course there is a lot more labor involved, as it is an auto conversion, and
requires a lot of custom built stuff. But the results I believe will make up for
the expended effort.
