Perhaps I can illustrate.
Each moving vehicle convoy and train has a complex trigger which causes it to start moving when one of our aircraft enter it's radius.
It looks like this :

You have to select exactly what will cause the trigger to do it's thing. To do that, you select the complex trigger, then right click and select Advanced Properties from the menu. You then get a screen like this, the box I have highlighted is what you need to manipulate.

So you click the little button beside Objects Script list and it opens the full list.

So on this screen the stuff in the left list is what will trip the trigger and start the convoy\train moving. The stuff in the right list is all the various objects and vehicles and what not you can use to trigger things. Since these practice rooms have all the WWII aircraft flyable in them, I added each of them to the left list. Its here you need to add the new aircraft, the Me-262, P-38, P-51 and Tempest. You'll see they have multiple entries sometimes, not sure what the -c means. I just added the first entry for each plane, like the p38j25 one I have selected here. Once they are added people flying those planes will trip the triggers as intended.
I could update the maps and re-upload them, but I think you said you had modified them for the dserver? So I don't know if that would help you.
