Extras to add to the MiG-21 MFN aircraft.cfg file can be best done with the standard 
Notepad windows application.

To have kneeboard Checklists and Reference in your sim by pressing Shift = F10 add 
this to each livery section ([fltsim.XX]  in the aircraft.cfg file:

kb_checklists=Mig21_check
kb_reference=Mig21_ref

I modified Dutch Owens FDE in the [autopilot] section by adding an entry:
max_bank=28.000000 in order to get more stable behaviour of the aircraft.

To have VC cameras in your sim add this to aircraft.cfg file (I did it at the bottom of 
the file, although to my experience it doesn't matter where you place the camera sections....)
