I didn't feel the included battlescape skin for the 'Warbird' looked very piratey, so I spent a little time in photoshop and made it more to my liking. I made changes to the basescape plane sprite (hopefully the palette is correct), and the pedia image.
If you want to make your own changes I've included a photoshop file I was using to edit the sprite, I'd recommend using MapView then TileView and lastly PckView for exporting and importing the whole gunship as a spritesheet. As far as setting up MapView to view Piratez craft,
see this thread.
