You guys take the fun out of staying in character
When you start a mission, it creates a file called _gen.mission. If you have a problem with a mission, they ask you to submit it. You can also use this to save a career mission (under another name) and fly it again later.
What I did was to start a career mission but in the load-out right before you start, I exited. I then used the ROFeditor to load the _gen.mission and give myself a DH-4 instead of a RE8. Unfortunately, when I went back in and reloaded the mission, I found I was back to flying a RE8.
So why am I trying to give myself a DH-4. We I've invested a lot of time with my Squadron and built up my pilot. I don't really want to throw him away and start again, and for the life of me, I can't find the transfer button LukeFF talked about. I was trying to liven up my campaign by flying something a bit different.
