I tryed to play the Kfir C.7 and its realy hard i would even say its the hardest plane to stock grind in the whole game. It either needs a br decrease to 11.7 or you have to give it Pythoon 3 as stock misssiles. bc there is nothing you can do without Chaff and AIM-9Ds at 12.0 facing 13.0 every second match.
