From one of the videos, the Turbo and the Supercharger are actually in parallel so you can lose either one and keep running. The supercharger will only provide 50% power. The counter-rotating was in the press release 15 days ago. So that is fairly recent. In terms of what it takes to make it counter...

Per this PR, DH is developing a counter rotating version. https://www.deltahawk.com/2024/04/10/piper-aircraft-and-deltahawk-engines-to-co-develop-stc-for-pa-44-seminole/ The old FAQ page had some information about CR engines and what they were doing to support them. I do not recall the details, and ...

everyone can work on it/familiarity everywhere Why wouldn't service availability for the Delta Hawk be even less than the Austro? Diamond has rolled out more locations that DeltaHawk has. On the flip side, DH has many fewer parts (no ECU, no valve train, no transmission...) and DH has a much shorte...

The super charger is for starting the engine, inflight restarts, and to provide 50% power in the case of turbo charger failure.
I do not understand how it works, but supposedly once the turbo comes up to speed the parasitic load for super charger is minimal and runs continuously.

Personally I wouldn’t own an Austro, especially on a DA40. The good news is they are exceptionally docile handling aircraft with best in class safety (like a 26G cage for the occupants). Like a few others, the determining factor is proximity to an Austro service center. For me since I am still work...

Cirrus gear is not "bouncy", it is on the stiff side. Diamond and Cessna gear are more forgiving of poor airmanship. Having watched way too many Cessna pilots land with all three wheels or occasionally the front wheel first; you can see how with low wing planes with much greater ground eff...

Alan, Join COPA. You will learn a lot about Cirrus, and you can ask Rick Beach and others about the crash statistics. Beyond access to the forum, COPA has many very informative articles in the regular magazine, they run the CPPTs and many other activities. When it comes time to address problems on a...

Out of curiosity, do you still own N1446C?

No, sold my piece of the partnership last summer. We were planning to leave the area, but that fell through. My partners are great guys, and found someone to buy me out.

@alanhawse The data shows exactly opposite what you are arguing on Cirrus. When you compare Cirrus SR22 accident and fatal rates against equivalent planes, e.g. DA-42, Bonanza... You will find that Cirrus is has lower rates or is extremely close to the point it is a statistical tie. The DA-40-180 is...

I doubt it will pencil out. I did it before with an SR20, the break even for the additional costs (insurance, MX...) was around 100 hours a year; and I managed to lease it out only 150 hours a year. So it did reduce my costs some. Downside, I was flying 150 hours a year, if there are two of you now,...
