SO at the end, China might as well just built a fighter plane SIMILAR to the F-35 in ability and class but frame-based on the J-10, since the Jian-10 is flexible and VERY manuverable...
Then again, if the J-10 needs redesigning... itz gonna take forever and just how much is it gonna cost China? American Raptor's cost is like above 100 million and the JSF is only 33-38 million, same cost as the Su-30, I mean if China can built a version comparable to the JSF and cost just around that much, China might as well built it
