"By the way, what about model aircraft and helicopters? Do they have the same weight and height requirements? "
Yes. Yes they do. And why on Earth would they not? These rules will apply to all remote controlled model aircraft, which includes all variants and versions of without any other distinction. Its not as if "model aircraft" and "helicopters" have not caused serious injury or death in the past. That is not the exclusive preserve of that other model aircraft, the multi-rotor colloquially, and incorrectly, known as Drone in popularspeak.
