Heh!, Heh!, Heh!, truth is the Indian guy knows just as much as any one of us, and we are ALL speculating based on what we actually do know. Truth is, most Westerners have far more information on their own aircraft than any of us, except possibly the few people in or near the factory, or that have some inside connection will ever know??
Whether it has a stealth coating at this stage is beyond irrelevant, and it likely does NOT?? reason being that aircraft in "test" are constantly being dis-assembled, inspected, and re-assembled, time after time, after time. NONE of these aircraft will be in any way IOC for some time, then and only then will stealth coatings really matter as the J-20 is worked up, and its true capabilities or lack of them will be explored.
It will have strengths and weaknesses, just like any other airplane, but remember, the Brat has been telling you that high end L/O aircraft are very expensive, very complex, and very rare by their very nature.
The Chinese like everyone else are in a budget crunch, their very ambitious plans have been dialed back like everyone else's, and in spite of the many protests to the contrary, the Chinese economy piggy-backs off the US economy, and vica-versa. I just have to chuckle, all these back and forth "tweaks", only encourage the world to realize that we do need to be prepared for people to "get out of hand", and if we don't give heed and prepare we are a bunch of dufuses? which looking at the BHO team, including HRC??? is very likely??? and I'm going to chuckle once again? what else can we do??? crazy, but the J-20 is coming along, albeit slowly, and surely, she will mature, just as the F-35 is maturing, and in spite of protestations to the contrary, she is currently suffering "growing pains", fact of life fellers, fact of life in the "big boy world".
