How do I change which aircraft loads when I choose a flight? I have downloaded the MV Challenge flight for the Concorde which uses the old FS 2000 Concorde but want to use the new GMAX Concorde from Project Mach 2. Probably quite easy but I haven't stumbled on how to do it yet!

Open the *.flt file with Notepad or Wordpad. Search for:&l;Plane.0&r;Aircraft=Cessna Skyhawk 172SP -- Change this to the exact title of the aircraft you want to use, then save the file.
