The plane was designed in XP9 so it won't directly go over to XP11. Back when XP10 was new there was a thing called the xpfw 757, a free 757-200 designed for x-plane 8. You could convert that to be able to run in XP10 by opening it in the XP9 plane maker and updating it to an XP9 .acf file. I unfortunately can't get xp10 on my current computer as I don't have a disk drive but if you have XP10 you could open the .acf in the XP10 plane maker and then it might work for XP11
