Hi Mal,
There were gauge issues and those that FsX wouldn't accept I changed for more modern ones. A couple of the models had texture issues so I left them behind (we have to remember that it's an Fs2002 plane, so about 9 years old now!) and I used a set of textures that gave good reflectivity. I think I had to change out the prop texture and darkened the glass alphas to minimise the "behind the clouds" issue.
Beautiful though this Lyons masterpiece is, as I mentioned above it is elderly and isn't on a par with a contemporary, made for FsX aircraft.
