Ah yes...what I like to call the "Flanker Dilemma" since it wasn't until Marc released it some of us noticed the undermodeling of the R-27 and R-73 as opposed to what various sources said about these weapons.  
  
This is what tflash at SimHQ suggests changing in the weapons pack (using weapons editor): 
  
Current values in Weaponspack: 
  
weapon---Accuracy--Lock-on-Noise re-CM rej---Seeker----turn rate 
AIM-9L---95------- 85------- 95------- 95------- 2,5------ 32 
AIM-9M--- 95------- 90------- 95------- 95-------2,5------ 32 
AIM-7F--- 90------- 85------- 90------- 80------- 6-------- 16 
AIM-7M--- 90------- 90------- 90------- 85------- 6-------- 21 
R-27R---- 80------- 80------- 90------- 40------- 5,6------ 24,5 
R-27ER--- 80------- 80------- 90------- 40------- 5,6------ 24,5 
R-27T1--- 85------- 80------- 90------- 30------- 3,5------ 27 
R-27TE--- 85------- 80------- 90------- 30------- 3,5------ 27 
R-73M1--- 90------- 85------- 90------- 30------- 2,5------ 48 
R-73M2--- 90------- 85------- 90------- 30------- 2,5------ 48 
  
change to: 
  
weapon---Accuracy--Lock-on-Noise re-CM rej---Seeker----turn rate 
AIM-9L---95------- 85------- 95------- 95------- 2,5------ 32 
AIM-9M--- 95------- 90------- 95------- 95-------2,5------ 32

R-73M2--- 95------- 90------- 90------- 90------- 2,5------ 48  
  
  
  
I think you'll like this set up better :)
