That is the exact point....FAA regulates and controls the airspace. They have the laws and regulations. Just because the words "model" are not written explicitly. It is explicitly stated what can and can't be in REGULATED airspace. Air ports and corridors are regulated and controlled airspace......it doesn't matter, manned, FPV, model airplane or UFO. If your in the controlled airspace your under the FAA laws and regulation by default. If they could catch them, ET would be fined for flying near a airport in the regulated airspace.
The FAA never wrote a regulation for model airplanes or sUAV's. There were no laws written either. This was specifically pointed out by an NSTB judge in the Pirker case last March. They do have laws and regulations for obstructions to airspace however. Although there is nothing specific about model aircraft there the FAA can say you unlawfully obstucted a full scale aircraft. In the Pirker case however he did not obstuct any aircraft and they were trying to fine him for unsafely flying an FPV model aircraft.
