Given its huge PLA-star on details I'm sure it is a prototype only.
Yes he is.

it's a highly accurate 1:1 scale model at a theme park near the mentioned airport, there's also a 1:1 scale model of a J-10C
In case you have a direct question for him.

He isn't too active on this forum though.

Just for full disclosure, what was said is that a J20 was spotted at RiZhao (civilian) airport in Shangdong province.
The key sentence exactly translates is:
‘Don’t know if it coming here is related to the navy’ (I don’t have the exact eyebrow-lift-sideways-glance emoji).
I leave it to each member to decide if the question is rhetorical.
Not applicable on the J-20, as the engines are too close together to achieve a lot of yawing moment (unlike the B-2). Also, for artificial stabilization in a Su-57-style yaw-unstable configuration engine throttle response is way too slow.

If that's what was said then I would take it as purely rhetorical... author was likely just 'thinking out loud'.

The F-22 performs yaw movement purely 'peddling' the control surfaces in maneuvers like the "double peddle turn" and the "360' turn". Even the F-35 did it at the recent paris airshow - .
Is this possible with the J-20 layout? What if the Canards move differentially causing more drag on one side?
Yes, and its just the "pedal turn", slow the aircraft with full aft stick, and very low power, basically right or left pedal to the floor, kinda a flat spin on purpose, but the F-22 and the F-35 are very safe and happy chicks, the pedal turn is typically 180 degrees and then recovery, by opposite rudder to stop the spin, and forward stick to "break the stall".
but yes, I definitely see NO reason why the J-20 wouldn't do a very nice pedal turn, its disappointing for us all? that we have yet to see a real flight demo by the Chinese?? the US does it, the Russians do it, the Chinese could easily replicate those fancy airshow maneuvers.
in fact there is NO reason, the "beast from the East" couldn't fly the F-35 high program,,, in fact they should at their earliest opportunity! thank you for your "link".
the fact that we saw some very tight turns and aileron rolls from 2001 and 2002/4 were very encouraging....
those bad old canards won't hurt a thing, you should be able to go post stall in the J-20, while holding aft stick to stay post stall, push a pedal to the floor, rotate as long as you want, and effect a nearly instantaneous recovery by opposite rudder and forward stick.
I did some departure stalls in our old 172, and as long as the ball is in the center, it tends to depart with a little "tuck" in the direction its banked, in fact I had to work a little bit to get it to "depart". But I can assure you, if you didn't pay attention?? and allowed the ball to out the center?? she would tuck into a very nice spin! in fact I once did an unintentional quarter turn spin in an older Cessna 150, scared the krap out of me and my College Buddy, but pulled the throttle, opposite rudder, and forward stick, it stopped spinning on a dime! BOOM, and then recovered from the very steep nose down attitude,, ah yes, fun to be bit in the butt, but recovery was intuitive to the old Brat, actually gave me a great deal more confidence as I reflect back on that day
