To all those who understand the structure of files in FS2000, is there a special relationship between the panel and the .air file. The reason I ask this, is because I found a great 747-400 model and .air file, but I want to use a panel (from Jumbo 3.0, see message "Jumbo 3.0 Anyone?") in conjunction with this greate 747-400 model. Will all the switches work? Will I need to change anything? Thanks for the help.
