I’m wondering if for a future update the sounds can be revisited. The real Dart engines had an extremely shrill shrieking sound at idle and lower power settings that transitioned into a bass-filled rumble at higher power. It seems like the high pitched shrieking was toned down excessively for this release, especially in the exterior view. I’d encourage an analysis of the sounds included in AFG’s old freeware YS-11 for FS2002-2004 as an ideal exemplar.

I watched my grandparents board a Piedmont YS-11 in 1970 at what is now KGSO. I still remember the shrill metallic scream of those darts to this day. It's that kind of sound!

Thank you for this topic, you were able to define with precision how a Dart sounds just using the right words. I used to fly the AFG YS-11 a lot, and the sounds on that thing are really the closest I’ve ever seen to the real one. This IniBuilds YS-11 just needs a few minor corrections and revisited sounds to be a well rounded fan favorite local legend! Inibuilds, there’s a lot of videos on YouTube, and also the AFG Freeware to use as a reference, it would be AWESOME if you guys give another chance for those Dart sounds! 
 

Best Regards!
