FS2004 T-6 Harvard Sounds. by Doug Smith This sound folder can be used in any T-6 Harvard aircraft for FS2004. It has an authentic snarl heard when the props exceed the speed of sound both from the cockpit, and outside the aircraft. I recorded the sound myself and incorporated it into the fabulous Wasp sound bundle by Jay Farmboy McDaniel. (fb_wasp_sound. zip) Disappointed by the T6 sound packages available, I believe this sound bundle will give you the truest sound available and it is my pleasure to share with the Flightsim community. Thank you FB for your fine editing. Replace the sound folder in any T6 folder with this one, and alias all T6s to this folder. Enjoy D. Smith
