@airfighter Ah, thanks for the reply. I have never flown an aircraft with Autofeather (ie AFX). I found a few good articles discussing it which helped. I have read quite a few articles on the real Avanti II and gleaned as much as I could with regard to climb performance, fuel burn at various altitudes, expected fast and efficient cruise speeds, etc. I will accept your assessment that the propeller simulation is off, but from what I have seen, the overall performance of the aircraft seems pretty damn good, even if the actual indicators are not aligning well with the position of the levers, etc. So far I am delighted that it is as accurate as it is.
