 the J-10, despite rumours is not based on the lavi, chengdu was already working on a canard plane before the lavi program. the fact that you bring this up, raise question on sources of information, i hope it is not wikipedia ) Chengdu actually got technology from US (before USSR collapse, US allow chinese engineer to come to US and work with US defence contractors, this is documented) and Russia (after). both transfer were however incomplete and Chengdu had to adsorb the technology, the fact that they got input on modern technology form the 2 major power, is what make it logical that they can develop modern planes now.

 but seeing is believing, we have video of a thottle up, thottle down test on landing http://www.tudou.com/programs/view/VDrpLi8EER0/ showing it has operational engine. also the article you read is regarding J-10 problem which is unique to single engine planes. the J-11b has been equipped with chinese engine and flying in the elite unit near beijing, it hard to dispute something already in service.

 again i remind that this is just a prototype, it is not a production type. no one here suggest they can make a 100 of these economically. but making 1 working prototype is not that hard; remember that F22 prototype emerge years before US has the ability to mass produce them, that is the whole point of making prototypes, to solve problems. i really don't understand why some are acting like the existence of prototype must mean China has reach the same level as US, that just crazy thought. 218.186.8.234  00:57, 6
