Consider this my request for a subscription to your rotary engine
newsletter, also where can test engines be purchased...Thank you
...Roger Clark

Short blocks can be bought at your local Mazda dealer or
at wrecking yards. One must add a gear box, intake manifold
and cooling system for use in an aircraft.

Nobody is building a firewall forward packages as the engines
are very low cost. There is no money in it when one can
buy an engine for several hundred dollars. It is up to
you to equip it for aircraft service.

Read the web site for a list of part suppliers.
