Ok, I've used google translate. I moved the position up and slightly more back. Redownload from the link above. This version also includes the fix to the view range.
Note, don't compare this with DCS. Our cockpit isn't as accurate, and the sizes aren't the same. For example, if we have the head in the correct position, turn round and look at the seat back and you'll see it seems quite low. Maybe the seat needs resized.
