I often swap radios and gauges between aircraft. I have done this many times in the past by simply editing an aircraft's panel.cfg file and replacing the name of a radio or a gauge with that of another. I recently tried to replace the radios in the Mooney Bravo, though, and I was unable to do so.The situation is this:I purchased the DreamFleet C177 Cardinal (absolutely fantastic aircraft, by the way) and I liked its radios so much that I decided to swap them into the Mooney Bravo. So... I edited the Mooney Bravo's panel.cfg file and replaced the line: gauge01=Bendix_King_Radio!Bendix-King Radio Nav-Comm 1, 0, 29with the line: gauge01=DF177EC!KING_KX175B_NAVCOM_1, 0, 29Not a good idea! - When I load the Mooney Bravo with the changed panel.cfg file, FS2002 halts with a message box stating: "Microsoft Flight Simulator has encountered a problem, and needs to close. ...send a report to Microsoft... etc."As a test, I tried to swap radios between two of DreamFleet aircraft - the Archer II and the C177 Cardinal, and that too caused FS2002 to crash. I asked about this in the DreamFleet forum but I have not as yet received an informative answer.Can any of you Avsim panel experts tell me what might be causing the FS2002 crash, and provide me with ideas as to how I might work around it?Thanks in advance for you thoughts,Robert Rent
