A little late now, but maybe the attempt to use an automotive engine designed to run at 15% power for most of it's life versus 75-90+% power wasn't the best idea. I don't mind the automobile engine if it comes with automobile economies of scale. Benz sourced Austro engines used to affordable in the...

Using this chart from the Austro Operations Manual, with climb power set to 92%, we should see 92% up to 10,000ft. Then 87% at 12,000, 80% at 14,500 and 75% at 16,000. I am seeing better than that ... eg 88% in climb at 14,000 on my last cross country flight. So it appears the engines are performin...

As far as I know, the turbo and exhaust manifold are all the same between the 42 and 62. Only difference is higher boost/manifold pressure in the 62. They both hit their critical altitude around the same altitude but the extra few hundred RPM may give the 62's Austro's an edge.

Russ, sorry for the delayed response. Here you guys go.

Plane has sold. Thanks for looking

Alright, nudged my shop after Marlon checked in and they had a report to send over. It's thorough. A whole teardown and inspection: release torque checks, hypotheses on probably cause, photos closely identifying all relevant components, records review, etc The #4 piston failed with a hole through th...

Nothing. Checked in with the shop again. Sort of gave up on it.

No issue sharing. I had one engine fail in flight and decided to change the other so they were matched. I kept the remaining good engine for parts.

New price at $825k

And thanks to Russ--I omitted a few of the key options:

long range tanks
TKS
Air conditioning

Thanks for looking

Is the 5°C limitation an OAT limitation? Or fuel temp limitation? I was impressed how much the fuel pumps heat up the fuel on a cold night. -18°C (ISA-1) temps outside and fuel temps were still a nice 16/17°. This was at least an hour into the flight, too. https://i.imgur.com/u69OfA4.jpg Reminds me ...
