Obviously such small surfaces wont flex as much, the wing example was something I quickly found on YouTube so I could give you a better idea on how it looked in real lifeThanks for the reply. I understand when it comes to wings. But I'm not too sure about the canards. Perhaps we should expect it to behave much like the wings, perhaps we shouldn't, I don't know. That's why I'm asking as my knowledge on this point is rudimentary at best.
This is more of a physics and material science question so AFAIK the general rule is that small surfaces flex much less than bigger ones. With these high speeds, and sudden changes in the aircraft direction the canards must flex otherwise they will get destroyed.
I am sure the Chinese did their own homework before investing billions into this project.
