I Actually had already done this Just as a test and works OK never found any issues with renaming them for the OVII . I did loose the Icons within Xplane UI but I guess Because I never renamed the 2.png files in the Model Root folder, I have now renamed all the Icon files and the ones included in the liveries and everything is OK.
As A further Note , the one problem I can see in doing this myself is that, any other software that checks against the ACF name (Im think smart copilot here) would throw a You must be in the same aircraft error!
I also Yesterday created a smartcopilot file for the OVIII Posted it in the downloads section here would be good if we could get some Mooney users testing and reporting any problems.
Cheers
