I found out after looking through the files for quite a while. For anyone in the future who may want to do the same:
Turns out it was really simple when you know how to do it.
In \Data\Sim\Acdata
open the file for the plane you want to change. There’s two things to change: The cockpit visuals and the avionics. Avionics are controlled by the line beginning with typeAC
. Changing this from 5 to 2 turns it into a Viper. I think this is exposed by the editor as well, so you can see what each number means.
For cockpit visuals, change the line starting with cockpitName
. The name corresponds to folders in Data\Art\CkptArt
. Just removing the name defaults it to a Viper pit.
Obviously a good idea to make a backup of any files before tampering with them.
