While outside of G2 (it is not running) and using your Windows Explorer go to PROGRAM FILES and then to REAL FLIGHT and then to the COLOR SCHEMES folder. There you will see file names of those color designs/schemes that you downloaded (they will have a recent date. You have to "install" them by either right or left clicking on them. Which click to use, depends upon where you downloaded them from. Try your left click first and follow the directions.
If you download from this site:
http://zeus.rcwizard.com/fubar_hill/G2.htm
you have to do a right click. This creates another subdirectory and in it is your active color scheme file. MOve this file out of this subdirectory and on to Real Flights main listing of color files. whew!!! Once done, you can then delete the empty source directory as well as the original zipped directory as these are not needed anymore......they just transported the file that you wanted. Be careful and know what your are deleting though.
Then you can start up Real Flight and your downloaded color schemes should be listed along with Real Flight's stock schemes.
Hope this helps!
