Warwick,
The Mig 15 CG is measured from the rear of the wing root forward. It is measured dry with wheels down. the forward most measurement is specified at 7.75 inches the aft measurement is 7.25 inches. Hope this helps.

Also, make sure you have a full UAT when checking the CG.
On the BVM website in the MiG addendums, it is sugessted that you use the aft CG for better landings, and 35 degrees of flap, instead of the earlier setting of 45 degrees.
