Question about late Mirage IIICJ modification data.

[KamilP]

Hi

In the book "Israeli Mirage and Nesher Aces" by Shlomo Aloni, I have found the information that: Throughout its 20 years of service, the Mirage III underwent just four major technical changes in IDF/AF service – theintroduction of the ‘holding switches’, replacement of the Cyrano with ballast, swapping the Atar 9B for the 9C and, finally, removal of part of the ballast at ace Kobi Richter’s request in 1977. This moved the centre of gravity backwards, cutting minimum speed from 150 to 120
knots and increasing maximum ‘G’ from 6.5 to 7.3, thus improving sustained turn rates".

 

I would like to create this late modification of Mirage from 1977 for SF2 by:
1) changing empty mass of plane;
2) changing inertia of plane;
3) changing center of gravity position of plane
but I need some additional informations which I can not find:
1) have I to change any other data in DATA.ini file to properly reproduce the changes in flight model?
2) what is the mass of Cyrano Ibis radar/nose ballast?
3) how much of the ballast was removed?
4) how much has the center of gravity changed?

Please help.
Thanks in advance.

I get smoked in the Mirage every time I think I got an idea.
