SU30SM thrust doesnt correspond the the real thrust of its AL-31FP engines in the Dev server. Both engines have a max afterburner thrust of 11.660kgf, although if u check a couple of sources, you can find out that its real thrust is actually 122.6 kN (12.500kgf). Looking at the fact that the SU30 is a heavier 2 seater aircraft, i dont see a reason to set the thrust to a lower value given the heavier weight that its got. To prove the my point, ive attached a couple of sources about the specs of its engines and honestly if Gajin wants their game to be realistic, then they should think about adjusting the thrust again before releasing it because honestly russia needs some tweaks to be top tier competetive again, it hasnt been doing too good lately.
P.S: Trust me, sooner or later someone will release unwanted files.
