My supersonic plane starts shaking in 600 m/s or more. I tryed to add some struts but it doesnt help . Do you know what do do?

That plane has A LOT of control surface area. I would suggest removing about half of them, because I think your problem might be that they're exerting all sorts of stresses on the craft. 

Also, your thread has been moved to Gameplay Questions, and welcome to our forum.

You could also reduce the maximum deflection on all of them to 50 or so to get the same effect without changing the look of your plane.
