For the video, it looks roughly like 135 degrees in 4 seconds, or around 30 seconds ITR. Eyeballing it, it would be safe to estimate turn radius at about 100-200 meters. If it's a 9G turn, that puts the J-20's corner speed at between 338 and 478 km/h. Since the camera doesn't move much, though, it would be great to get a good corner radius estimate, though.

J-20 did participate in the exercise.
Here is a screen cap from another TV segment on the same exercise. You can see a J-20 taxiing before a Flanker (J-16?).
Probably the same exercise where they decimated the 4th gen aircraft and SAM defenses.
What are you talking about, if you're referencing the video that Hendrik put up,,,, theres nothing here that would even come close to allowing you to extrapolate those numbers??? post the segment that you believe back's up these nonsensical numbers?? 9Gs??? where are you even coming to that conclusion??
That's typical for Inst

@AFB: the reason we assume 9Gs is that the typical modern aircraft G-limit is 9Gs. The PAK-FA claims an 11G limit, while the Super Hornet is limited to 7.6Gs.
As to the rest of the video, we see a 100-120 degree turn in about 3 seconds. The corner radius is between 100 and 200 meters, using the J-20 as a yardstick for distance and noting that the camera is relatively static. This implies a velocity of 350-450 km/h using the 9G limit. Funny thing is, 9G at 450 km/h should actually be 40 degrees / second, so I need to recheck the video.

Looking at the video again, but at full screen, it's a 22.5 degree/sec turn of 4 seconds for 90 degrees. I'm trying to figure out how many J-20 lengths the J-20 is from the center. Most likely, this is not a 9G turn, given that the radius looks like 5-15 J-20s, or 100 to 300 meters. I'll try to measure the video a bit more closely. So this is possibly a low-speed turn below corner speed.
Okay, this looks like the turn radius is between 151 and 400 meters. Assuming 9G (and the aircraft slows down a lot towards the end, so assuming it hits turn rate limits is not impossible), you get between 414 and 616 km/h for the maneuver. It's difficult to play with, since the turn looks elliptical, not circular. Still, the funny thing is, at 616 km/h, 9Gs is still 30 degrees / second, and at 414, it's around 40 degrees / second.
