Playing DCS Liberation dynamic campaign and single player missions in general, 
I noticed that US made planes completely dominate in AI vs AI scenarios, 
since the AMRAAMs trounce any "comparable" Russian missile in terms of kinematic performance. 
Due to how the AI acts in BVR, even the Sparrow has an edge due to its lofting capability. 

To make AI matchups more interesting, I've given the R-27ER the ability to loft in a manner similar to the Sparrow. 
Range, mass, drag, etc. weren't changed. 

The R-77 also received the ability to loft, alongside getting extra mass and a boost phase, again along Sparrow lines.
ECM resistance tweaking is WiP.

The results so far have been promising - both missiles give Russian built aircraft a fighting chance agance AMRAAM carriers,
without being blatantly broken like the R-77M from the Su-35 mod.

Ranges of the Vikhr, Kh-25ML and Kh-58 also got tweaked.
