ok than i believe u on the maneuverability part, that should be fixed in a few years. but overweight by 1.5 tons? wow that's a lot that means that the lca should be 4000 kg? that's less than a trainer aircraft (the hawk weighs only 4400 kg). i think they will reduce the weight by 300 kg max since this is the 2nd a/c they have built they dont know weather they should make some parts thinner or thicker and they just kept them thicker to be safe.
but everything else i said is a fact although the aesa hasn't been integrated but the fact that it has been ordered means it will be and when the 1st squadron is raised in 2010-2011 all of the lca's will have aesa, and the aesa alone is a potent ew system, that combined with jammers, composites, and a small size should give it less rcs than jf-17, and also another ew will help its survivability. not to mention better avionics.
so basically the jf-17 scores over the lca in close range combat and maneuverability and the lca scores in bvr combat and strike thanks to its aesa, ew systems, and better avionics.
