Indeed it does, and I long to see some "blue smoke " from all these birds although these vapor clouds are "telling the truth" as well. I would love to see the J-20 covered up in blue smoke, I understand the T-50 to a certain extent, the LEVCONs do react independently, and in concert with the other control surfaces?
The J-20 on the other hand is a much different animal, and those distant coupled canards take a little more thought? LOL
of the keypubs forum hassomething interesting to say
i quote.............

Excerpt taken from an official company document from earlier this year:
Either the wording "Indian variant" is basically a discrete way of saying 'Stage 2 prototypes'...or the differences between the Russian and Indian types is more fundamental than just 'source code'.

@Air Force Brat, what do you think,???????????????

@Air Force Brat, what do you think,???????????????
The Indian FGFA was to have several principal differences from the Russian PAK-FA, number one being a pilot/weapons system operator? something like the F-4, F-14, the idea being that two heads are better than one, and improved avionics/weapons systems?? Now I have never even seen design drawings of the FGFA, which I find a bit odd, since if we were to propose a two seat F-35?? (not gonna happen), but if we did, the first thing we would see would be an artists concept.
The disadvantages of that are weight gain, and lost space?? Using carbon fiber could theoretically reduce weight and RCS, making the FGFA not much heavier than the PAK-FA? and lowering RCS??? (also IMHO not going to happen). The reference to the higher composite content of the load bearing structure of the Indian version is to supposedly offer greater strength, while reducing RCS and weight? always a good sales pitch, and Sukhoi are master salesmen?
At this stage FGFA is way off in the future, and both Indian and Russia are focusing on the -2 version of PAK-FA, principally India coming onboard with "substantial" Capital?? and also a commensurately increased "design direction" and India wants/needs to fly PAK-FA if they are to lay out this kind of MONEY! So the Indians want more "input" and they also want more "access" to all the particulars of -2. The Russian's have historically over-promised, and under-delivered, and the Indians want to make sure they at least have a co-pilots position on where this project goes from here??
to all this I would add that the Pre-Preg carbon composites do offer additional structural strength and integrity, (the bonding agent being incorporated into the carbon fibre material, creating a more "homogenous" structure), and could? offer some reduction of RCS in the primary structure? I would love to see some design concepts, for instance is India thinking SU-34??? side by side seating? or J-15S tandem seating for the additional flight crew member, both have advantages and disadvantages, I myself find the SU-34 to be much heavier and less maneuverable, and favor the more "fighter" tandem seating.
they did say that they had created a priliminary design of the 2 seater ,
as had been posted in this thread. (not the pic, but the news)
if the 2 seater exists , we will know in December.
for the 2 pilot theory,
Weapons Systems Operator, in WVR combat is a great advantage, with Helmet (with a boresight of 60- 90 degrees) cued missile like the R74
in fact i believe one of the reasons why the MKI held its own against the Typhoon in recent exercises is the WSO.(extra pilot)

Your questions can not be answered, first because you need data from Russia that compares MiG1.44, S-37 and T-50 aerodynamically and second because in this forum you can not compare aircraft due to the chest dumping it provokes.

Just enjoy how the vortices are controlled by the LEVCON

The picture above shows how the flexing of the LEVCON keep the vortex near the wing
