I saw them at SnF, and they have a lot of interesting technological innovations in their engine. I am a real foot-dragger when it comes to clean sheet engine designs, but everyone needs to get a chance to prove themselves!

Worth keeping a close eye on their progress.
 
Bob Patterson was at Oshkosh, but don't believe he had a booth -- was often in HBC hanging around the Moose. Recommend you contact him through his website.
