You need to go do your research. The advantage of the stab for supersonic flight was discovered on the X-1, although it used a hinged elevator. The stab was not invented for the X-1. The whole stab moved only as part of the trim system, as on other planes. When going supersonic, Yeager discovered that the trim system provided control when the elevator didn't.

THe Wright Flyer used an all-flying canard, so the concept wasn't really new. It became standard on the F-86 and other fighters because of the X-1 experiences.
