As Ramius said (thanks Ramius), I did nothing much!!!
Only database changes and the 3d file switch.
So well inside SCS rules
And as I have done, I have a hull with wrong hardware! That's right.
I didn't fill like doing more as I am waiting for full patch. And would have to do all again with full patch.
But you can have that hull with the right hardware. You just have to create the new sensors and other hardware at the database and attribute them to the object.
Now... as I have always said, the only thing that cannot be changed is the loadout. But even that you can choose what you load and how much before you set sail on the horizon.
Oh... and non drivable alfa is much easier as you do not have to adjust masts and antenas
Cheers,
