You are clearly just a Pakistanis fanboy. I remember you are the one who brag about rejected J-31 is superior to J-20.Mr gambit your all posts are informative and logical, keep going, ignore these chinese fan boys, they do not have knowledge about Aerodynamic and i also agree with you that J-20 is based on MIG 1.44 but with lots improvement and innovation and it has frontal stealth only
If you clearly think mig 1.44 is just a J-20 with stretched fuselage to accomodate internal weapon bay and redesign air inlet without a major redesign. Surely, you know not much about aerodynamic.
