You should check out the parade video, the plane had amazing manurvability. As for AESA JF-17 will also be going through an upgrade once 250 are inducted into PAF (since they jumped the number from the previous 150) after 5 years, and AESA will might just be 1 of many upgrades, in modern war fare ASEA and situational awareness is the way to go.
Who ever said it costs $ 8 Million, the plane is going to cost around
$ 20-25 million per plane (the western equiped copy). It's a 4th gen plane (even ACM said it during the thunder briefing, and said that the MiG-29's currently in Indian Air Force aren't a threat, and more high-tech planes are being acquired to take on MKI and MRCA, probably a jump on J10s which will also be equiped with western tech, since PAF said it' didn't meet their specification).
