Yesterday I sent a zip file containing an a/c to my buddy. We have done this a couple of dozen times in the past. The a/c is properly installed and yet will not show up in the gane under the manufacturer or the "Any" aircraft search. I checked and it's not inside a folder/inside a folder. I've caught this in the past. Any ideas as to why this a/c is a no show in the game. It's in the a/c folder of FS9.
Cant thing anything more than a wrong installation...Probably this craft has some special instructions in the readme file...I just suppose...
Maybe sharing the link for this craft could help us to give you a more specific answer.
t-33a.zip on AVSIM will get the a/c. The one I passed on hasd several mods to the panel.
