Just was reading about these guys. Interesting that SportAircraft Works is saying that they are going to be putting these in their SportCruiser?
I can’t believe it.

Jim,
I have looked at turbines in the past, but never really got serious based on their very high expense to buy. But their relatively low weight (I could not find this one's weight) and simplicity always looked good. But several things also concern me - relatively high fuel consumption (this one is about 14.5 gallons per hour at 100 HP). Also, it is hard to even think about an engine that turns about 59,000 rpm. That prop governor must be really something to get the prop down to 3300 or less. I bet the prop is also very expensive - would probably have to be a full feathering one that would probably cost way more than a Jab engine by itself. I also wonder about that 90 degree shaft and exhaust set up. Would that be easy to get under a cowling? Oh one other thing, the way the light sport rule is currently written it has to be in internal combustion engine. That needs to change - or the future electric Sonex will have a problem.

Good points Buz, I also wondered about the cost and size. The high RPM does not bother me so much as Turbines typically have a longer lifespan between overhauls than internal combustion engines, but then I looked at the fuel consumption, and thought that I really didn’t want to just fly for and hour and a half.
But I could fly really high! Grin…

Well, I will believe it when they actually start offering the jabiru in the sport cruiser as they said they would 2 years ago. It may take much more time to figure out a turbine.
