Chengdu surely give it a nice name, dont they? Mighty Dragon sounds incredibly suitable for its size and shape.

Yes, it is a very pretty airplane, in a "Batplane" kind of funky kool way, outstanding discussion gentlemen, and your observations are very astute, and you are beginning to understand the complexities of this very "smart" airplane. To say that I admire Dr. Song would be a tremendous understatement, lets just say he is the Chinese Kelly Johnson, very sharp, smart, of course no one is likely to top the real Kelly, but Dr. Song displays that same kind of focused, practical, yet far out engineering mojo, not to take away anything from the engineering team, but simply to give them a persona to lead in a meaningful direction...
All we need now is for the Eng to slap all our knuckles with his slide rule, there is a very nice discussion of the many engineering attributes of the J-20s aero on the aerodynamic thread, you'll have to sort through some of the more obnoxious "discussions", but I would like to see those of us, including you Scratch, que up that thread and keep it running, particularly as we have these awesome pictures with vapor. and I continue to give credit where it is due, without the very articulate "walk thru" given to me by the Eng, I was very frustrated, when he finally got down to my level, the lightbulbs started to pop on, thanks again brother.
while it is a very long shot Deino, I would like to suggest that your "publisher" might send a formal letter to President Xi, I really think the Chinese people would love to see their airplane have an official introduction in Combat Aircraft Monthly

I have a stupid question. What are the holes along the center line of the fuselage for? I think the 200X planes don't have those (the ones on the backend of the fuselage nd only the 201X's have them??? I also just noticed a "hole" just in front of the cockpit in the pic above. I apologize for the amateurish language. I should pay more attention to the terminology.

Not knowing what the actual angle of attack really is in that particular moment, I believe it's still likely that the canards, while having a negative angle of incidence here, do have a (slightly) positive angle of attack. And therefore also / mainly contribute to a continued pitching moment?
To me that red thing in front of, and the light grey area behind the canopy are some kind of antenna / aperture cover. While the dark spots in the back are likely access panels to the stuff that's underneath.
Actually, those really small, black dots just in front of the canopy, if they really are anything, could potentially also be static pressure ports. Small wholes allowing ambient air pressure to enter the system to gauge altitude and so on.
A pattern of small holes on in aircraft while backed up by sufficient computing power - that's not a problem anymore - can serve to provide ambient pressure, speed, angles of attack and side slip information. Recently I saw on the Science page of the BBC website that bats use hairs on their wings to sense local airflow to react instantly on changes in wind and circumstances - a similar concept.
There are all sorts for reasons for such marks/spots/openings.
Sensors, or coverings for sensors. Covers to access panels. Covers for refueling. Coverings that are pervious to air and pressure for sensors.
Any number of reasons.
