Avweb produced two videos on the operation and description on Diamond's Austro AE300 engines.
The nickel tour is that they are heavier than Thielert's engines, but are promised to be much more durable.
A typical design decision is that the Austro has a heavier cast iron block, but this allows for the engine to be rebuilt.
I'm wondering why they didn't sleeve an aluminum block. That would appear to me to give the best of both worlds, though my experience with sleeved engines is locomotive engines, which are sleeved iron blocks, I might be missing something.
They are promising a 1000 hour TBO, and hope to extend that significantly as Diamond gets information from the field on the first engines..
