Dam good Copy ,we don't know how to copy AK-47
our indigenous Tejas took 43 years to develop and we spend 1.2 billions of dollar still nowhere near induction in airforce.
we just say MK2 will solve the problem and i think it's a Guinness book of record Longest time to develop Fighter aircraft.
And Here china is breaking every record and developing Fighter plane like 5th Generation J-20 And J-31
4.5 generation J-11b and J-10b
4 Generation J-17
i wander if this so call copy is not going to perform like original or is going to do better then original because they are develop a decade after the original .
We are using this flanker for long time but even today we have to send the engine to russia for maintenance it's a shame .
