I found a couple of battle tracks at Google Warehouse, and converted them to a number of 3d formats.  I did contact the author, but he hasn't contacted me yet.  These battle tracks are recreations of Battle Track from another game, so we should change the textures and the names--http://www.mediafire.com/?jzmmiganzwj & http://www.mediafire.com/?iknagqm1mag
