It’s the only known aircraft to have performed the tumble climb. It has good controllability at high AOA. If they didn’t want that then they wouldn’t have used ventral strakes.

It’s been like 13 years since we all read Dr Song’s paper. Hey did all our Chinese get better since then.
Do they have TVC? If not how are you so sure?
That looked more like a failed attempt at a clean unloaded roll than some sort of deliberate maneuver to me. J-20s have a tendency to deviate their longitudinal axis from their velocity vector when rolling, aka "tumbling"
Do you have a video of the J-20 pulling high AOA? I can't seem to find any where it does, at least compared to the F-22 and Su-57 which can both casually pull 90+ degrees
