Jim,
Hey, good to see you posting again. The answer is a little iffy.
If you're flying my stuff, the answer is an unqualified yes for any of the auto-installers in the ETO and MTO. As a general rule, I use add-on ships rather than stockers, and those which I can include are included, and those which I cannot are hyperlinked.
For anything that is not an auto-installer but is still something I did, the answer is a likely yes for the ETO and MTO, but I can't say that with any certainty regarding the Eastern Front.
If its anyone else's work for the ETO and MTO (such as Captain Kurt, Stuart277, or Devildog73) I can't say for sure. Removing the Japanese and CFS1 types are generally pretty safe, but keep them in a backup folder in case you need them.
