Gosh, that second one is great shot. Hope it gets posted on the internet.

Here's a good one.

Was there that bulge on the undersurface of the LERX on 2001 and 2002? I think I have not seen it on them. I wonder for which purpose it is...

Yes, just part of the housing for the main landing gears

The Wall Climbing Party!

Haha, ingenious pile of dirt

The engine is better mated with the fuselage, so it's not ugly anymore. The LERXes are most DEFINITELY straighter, and the LERXes in front of the canards seem completely gone.

Ditto, and some comparison photos:

Large but grainy...

So VERY clearly the J-20's aerodynamics have been tweaked in ways that aren't insignificant at all...the loss of the LERXes in front of the canards and the intake slope both indicate that they've adjusted how they manage vortex generation (or maybe those tiny LERXes just didn't matter that much). I'm wondering whether this makes the J-20's vortices closer to the kind generated by the F-22 and/or increases their lift coefficient/lift drag ratio...but my gut ins hinting at me that the changes aren't so significant that we'll see instant condensation at high alpha any time soon.

Maybe the tilted intake contributes now a lot more to the body lift then those LERX's. But what a beauty... This is worth every second watching at it to notices all the little details. But I do see some PS still cause there are strange changes here and there.

I wonder where the cannon is located.

Might as well post some more. It's a special occasion after all

Just like Mr. Deino, I too would love to see some photos from the perspective of that J-10 chase plane.
