Jeffchele yes there is a way of changing the planes in the campaings that come with it. Remember to backup the original campaigns first before you do change them.
Their is several ways you can do this. You can make backup copy of you CFS2 program or a you can change the name of the CFS2 program install from lets say CFS2 to CFS2 pacific or what ever you want. Then start a new install. This way you will have two fresh install CFS2 program independent of each other.
One will bee the one you play with all the time and the other will bee your backup program in case you mess thing up.
This way your origiginal missions will safe as is.
Now you need to go to:
http://www.combatfs.com/index.php?loc=downloads&page=downloads&FileType=cfs2-uti...Down load this program call mk_cfs_util_v2.zip . This program is one of the best available for CFS2. It will allow you to change planes in your mission folder and campaigns as well without having to open your mission builder to do the same procedure.
Just remember it will take a small amount of work since the campaigns missions that come with the game are linear and not Dynamic as claim.
You will have to go to every missions in the campaing folder and change it manually through this program.
This program is one of the easiest ever to figure out.
Good luck on your edevour.
If you have any question please come back.
PS you can change Ships and add AI planes from your addon as your opponents in your Quick action mode through this program as well.
