Yes - you can just replace the "wind.wav" that resides in the "sounds" folder, but not inthe specific planes folder.
OR, you can choose winds for different planes and place the wind file directly into the specific folder.
You can listen to the wind files in the folders for the Fw190s, F4us and Ju87 as examples that I included in the pack. basically emulating the whine of the 190s, the "whistling" of the f4us, and the siren on the dive of the 87.
