That isn't what he meant, in order to get them back you would have to re-add them back into the default core and default loadout files, and when you do this you won't be able to log onto the server because those 2 files will be different then what is on the server.
But if you don't want to play on the server then you can do the following:
1. Add the shuttle model into your Models folder
2. Add the lines for the shuttle into the default core and default loadout files, one for each race.
3. After that is done, load up the game and give it a try.
If it still won't work, then go to
my web page and get my TeamSpeak info from my forums and come on and I can talk you through it if you want,
