quick question for the team...goes for pretty much all your planes, i know they fly by the book with all settings, speeds, etc. but when you reduce prop pitch to top of the green arc, you just get that throatier, characteristic more powerful sound coming from the engine, and recommended emergency and takeoff settings usually call for max rpm, is this just audio, not actual performance? more simply put, more power with that little bit less rpm or not? thanks
That's exactly right, and you noticed it. When you pull the RPM back, you are taking a BIGGER bite of the air, and you are operating the engine at higher torque and "brake mean effective pressure" (BMEP) values. When the blades take a bigger bite, you will hear that, since our prop sounds are separate and unique sound files from our engine sounds. You will also hear that "throaty" sound, sort of like a Harley when you click it into high gear and motor on down the road. Yes, this IS more performance, not just "ear candy". These sound sets were VERY carefully tuned and if you listen closely you can hear the prop tone change independently of the engine tone, which makes for some very interesting and realistic sounds, especially during climb and cruise. There is actually a sweet spot (at or around optimum cruise) where the prop and engine sounds "synch up" and you get a beautiful, rumbling harmony.
These sounds were professionally recorded from an actual P-51D and the sound.cfg files and .wav files were engineered by professional musicians.
