Check out the below link to a recording of the takeoff sound from the P-51 cockpit. I didn’t record this sound file, but I obtained it from an online acquaintence that took it during his flight and I edited it. This is a quite accurate representation. Turn the volume up on your computer sound system. If the plaster isn’t starting to flake off your walls, you just don’t have it turned up loud enough. Seriously, you will never be able to recreate the real sound from your computer, but this is as close as you will get. Have fun and thanks!
