Simple edit: Open VSF Vehicles folder, open USS_Nimitz folder, click on Components folder, click on boat_CVN file, scroll down through elements to Motor element, find [fuel_time] and add a 0 to 36000. That takes you from 10 hours to 100 hours runtime at WOT...add another 0 for 1000 hours, etc.
Today I had to reinstall VSF due to a few problems. After installing it I discover to my absolute horror I have no backup of the USS Nimits. Is there anyone able and kind enough to send me a downloadlink for it? I'd be most grateful.
