Paul...This looks interesting for aircraft applications:

Very similar to the Dynacam. Certified for aircraft years ago. It
was designed as a torpedo engine. Would not run over 2000 RPM so that
limited it for small planes that need props to go to 2700 RPM. Duke's
joint between the piston rods and the wobble plate looks to be an
improvement over the dynacam line contact.

The VE on this engine will also be excellent. The resistance to
detonation is probably because there is no hot exhaust valve in the
combustion chamber.

This configuration is common in high pressure hydraulic pumps.

Paul,
I've seen the engine on a display about 3-4 years ago, but have not seen it running. I think it will be extremely expensive.
Heres another one from down here.., http://www.pivotalengine.com/gallery.html
When will your ignition system be available?? I want to try it on a cont 0200 in my Luscombe
cheers,

Russ

Soon but keep at least one mag :)
