I am an airplane fan, in general I like aircraft regardless of their nationality, sometimes i get in debates but i remember i should cool off, we are all humans, so I like to see J-20 as a technological marvel, I was born in 1971, so when i was young I love MiG-23 and MiG-25, later I discovered I love F-14 a lot, I am an engineer, but not in aviation, but still I love aircraft.
I follow J-20 because I love aerodynamics, I learned a lot talking with people online about aerodynamics, I love IAI Lavi.
I am a western guy because simply i was born in the western hemisphere, and I have to confess you I belittled J-20, with the age you learn to be more humble and honest.
Now I understand more J-20, it was made less stealthy than F-22 intentionally, the canards we set up there because tailerons push up the nose up, if they are statically instable, I mean the aerodynamic center of the main wing is ahead of center of gravity, the tailerons exert a tail up force so their lift is added to the aircraft if the aircraft is statically instable contrary to a statically stable aircraft where the tailerons reduce lift for a nose up pitch up force.
If they use canards the canards by being ahead of the wing, exhibit a high pitch up tendency, so they will give a quicker pitch up force.
J-20 was designed with that in mind, so they had to rely less in thrust vectoring control like F-22.
IAI Lavi for example is the best example, it was a F-16 with lower thrust but with higher instataneous turn rate than F-16.
Since Chengdu designed a modified Lavi, they applied that experience to J-20
