Fellow Bearhawk Builder is looking at various engine options:

When I suggest a Rotary is the response:

They consume too much fuel, as there was a Kit Plane article
that said they had much worse consumption than a 180hp 0-360.

Looking for solid fuel consumption evidence to post up.  RX8 vs RX7 also a plus.

Thanks,

Not true. Ask anybody flying them. They are about 5% worse and they will
burn auto fuel which is a 25% savings.
