Piston Dukes engine wind down
-
Just my personal opinion, which probably nobody wants lol, but I feel it should actually be shortened to match the sound of the engine stopping. The prop going back and forth at the very end is amazing, and something I've always thought wasn't quite right in flight sims, and is amazing to have now, but it seems just a touch slow at the very end there. There's just a bit more rotational resistance/friction in there IRL. (Source: I work on airplanes 5 days a week)
Not complaining though. It's absolutely incredible as is.

You're absolutely correct that it should be faster at the end. The friction becomes non-linear at low speeds in very complex and interacting systems like an internal combustion engine. These things seem dauting when I'm building the code to begin with, but once they're "settled" it's easier for me to make small improvements like this. I'll see if that's something I can add easily now.

Reciprocating Engine: 3.5 seconds to stop turning.
Piston Duke: 4.0 seconds.Turbine Engine: 53 seconds to stop turning.
Turbine Duke: 45 seconds. -

I only have a 73 Beech Baron to compare with but I think it's longer. I'll time it this weekend.
Thanks for your support and this amazing aircraft -
@Black-Square I think it's something about the linearity of the rates.
What I mean is this: In the Turbine Duke, the prop goes from invisible, to moving at perhaps 50-80 RPM (visually) in a fraction of a second, even though the NP indicates it's still spinning faster than that. But, after becoming visible, it does indeed take a while to stop. The animation doesn't depict a smooth deceleration from disc to visible blades at all (to whatever extent that it should be). Also, the audio seems to end long before either the NG or the prop stop spinning. It feels like the audio should last a bit longer, and the prop should have a somewhat more linear rate of deceleration. (To whatever extent that is realistic.) This is true of the TBM as well.
For example, the spin downs of the Lancair Evolution and FlyJSim Dash 8 Q400 in Xplane 12 seem a bit more realistic, although even the Dash 8's props just suddenly stop at the end of their animation... So maybe just the Lancair? It's audio is also more consistent in its taper off. Of course, I'm open to hearing that the Lancair is the one that's wrong.Finally, while the TBM 700 seems to take a while to feather its prop after shutdown, as per your linked video, the 850 and later models seem to feather much faster: https://www.youtube.com/watch?v=QfSDPwsIAlo
