Don't worry Ed, I following the thread, enjoying the pictures, but simply don't have much to add. I don't have the model installed, but had a quick look whether I could say anything about your sound issue. In the sound.cfg file there are 3 entries for touchdown sound. There are CENTER_TOUCHDOWN, LEFT_TOUCHDOWN and RIGHT_TOUCHDOWN. There all call for various "opencockpit_touchdown" files, which files can be found in the default sound folder. These are the "hard tyre bump sounds". In my default sound folder I have sound files called xlg_splasha.wav, xlg_splashb.wav and Xwaterloop.wav. Try to change the "opencockpit_touchdown" entries int one of these. Cheers, Huub
