i find it kind of redundant how it has both foward canards and TVC. Having both doesn't really provide that much maneuverability if it only had either canards or TVC. It only ads more weight and structural stress. Even with TVC on that Flanker, J-10 being smaller, lighter with foward canards I suspect it can match that Flanker if not better. TVC is overrated in my views, its mind game, when people think TVC on a fighter it means extreme maneuverability. What if you put TVC on either J-8 or JH-7, does it make it more maneuverable then the J-10. No
So this means the current systems of J-10 are better than SU-27/30's of PLAAF?
