It must be a light engine if they're shortening the fuse. Seems that a longer cowl and two more prop blades would contribute to instability, meaning a longer tail moment. The vertical tail is bigger, but is it enough?
Two stroke ?!?!?!?! Where are they going to find room for 12 big a** expansion chambers?
I think the two-stroke referenced was the diesel. 2-stroke forced induction diesels are thoroughly proven (and simple) technology- millions upon millions of Detroit Diesel 71 and 92 series engines are still running around out there. About the only downside for an aircraft application is that you can't run one with *just* a turbocharger, you have to have at least a small engine-driven supercharger in order to get the engine started and allow it to idle, and that's added weight.
True, but liquid cooling does allow a much higher output per unit of displacement, so that can be a wash. A few gallons of coolant still weigh less than more aluminum for a bigger overall engine. And if you're trying to stay under a displacement limit, liquid cooling looks even more appealing.
ANY facts on whos motor ( IO-12) it is and its stats or performance?
I was told by a 911 owner (replaced it with a squeak) that the flat 6 and all its ducting weighs more than the 350 (with aluminum heads and intake AND radiator) than the original air cooled and oil cooled set up.
Apparently this is not that unusual a motor swap from whative been told

I'm not sure that it can't be done.
Not convenient, but it can work.
It could be set is up to idle like a turboprop, high idle with the prop in flat pitch.
You could start it with an air cart and to give some manifold pressure until it spools up.
