Hi Again, Since purchasing and flying the Saab 340, I find that when I go to fly the Cessna Corvalis it doesn't start up and running, The electrics are off and so is the engine, These I can sort, but when the ATC asks me to enter the plane id (ie 4702) I can't get the numbers to show, pressing xpdr and code leaves all the squares blank except the last four. As I am a newbee it might be something I've done. Your help would be appreciated. Caravancol ps both the planes are in the same x-aviation folder.
