I always liked the rotary engine idea, so I will keep looking for that
high horsepower.
HOWEVER, I am a chicken. That engine will have alot of hours on it on a
few planes before I would even consider it. I still won't consider an IVO
prop, IMHO it is asking for trouble in an unforgiving environment. At
least the Franklin engine has been around.
I don't relish the lycoming/continentals in that they are old technology
etc. But they are really proven. When I was deciding on my engine, I
figured that the rest of the plane was experimental enough, especially
since I built it!
But of course, if no one ever experimented, we wouldn't be flying in the
first place.
What I am looking at as a possible project, is the Laser ignition. Seems
to be a really safe, and very reliable to squeeze some efficiency out of
the IO-360.
I guess it comes down to the risk/reward decision that each of us makes.
Sorry for rambling, just a few thoughts.
