I've asked this many times...
How do I get the AI MD-83,  Piper, ect. to work on fs04?  I've been going through looking for downloads, and even manuel instructions on changing the airplanes.
In other words,  "Help ME!"

Scott. These are the default AI Only aircraft that Maldeav is asking about. To make them flyable edit the AIR files with AirEd from the Aircraft Design section. http://www.simviation.com/fsdesign_utilities.htm

Change the Aircraft Type from 2 to 0. Then copy/paste in a panel folder from a similar flyable aircraft. Don't expect miracles. They have no DVC & were never intended to be player flyable.
