No the Dash's are quiet! Some may be just a bit loud (like some of the 100's), but the 200's, 300's are very quiet. The 300's engines are further back, so its really nice. 900 RPM on props, and no wind noise, because we can't get over 230kts in level flight, well makes for a nice quiet cockpit.. 750's are the best for the 8's..
