Interesting, but do you have any proof of such upgrades? Specifically to the 27 fam. and the 73. because I do know some people, you know.
I am not saying the kinematics and aerodynamics of our current R-27 fam. in DCS are correct, they obviously lack a proper CFD treatment but for that matter, you shouldnt even be able to fire an ET if there are any clouds or the target has active or passive countermeasures.
