After excessive testing… the Su-30SM can barely even keep up with an F-4E Phantom in a dogfight
The engines not only do not produce enough thrust for the aircraft to be competitive, the excessive drag also significantly hampers your flight performance
You may say “but you can disable the AOA limiter” and that is true but even then you stand no chance with aircraft like the Eurofighter and Rafale not only outturning you but also maintaining a lot more energy so you will just lose the fight
I would make a poll but most people will vote against this without having played with or against this aircraft so it would be quite unfair.
if you can’t win F-4E in dogfight using Su-30SM, it’s not bad engines, it’s bad pilot with low skill
and EFT and Rafale are lighter then Su-30SM, that is heavy fighter (what did you expect?)
