What about the
J-7?
As of now the J-7 are more successful than your LCA.
Your Tejas are still hanging around waiting for their indigenous "GE F414 engines" as we speak.
You think China is incapable of fault finding and over many years never learnt from its mistakes?
Mind you, Jian-7 is still operational today with the latest being the J-7G variant:
If the J-10 is so poorly designed, we would not be producing; J-10B, J-10S and developing the J-10AH variant. Instead, we would be stuck with the J-7 and we would probably be knocking on India's door for some 'Tejas 101'.
Thankfully, it was the India doing just that, knocking on westerner's doors, fearing Pakistan's JF-17 and China's J-10
