The U.S. FAA proposal keeps commercial / public operations UAS (drone) below 500ft AGL and more than 5 miles from airports.
This should effectively keep them separated from "full scale" piloted aircraft. It would also instill some required knowledge base of operations, rules and regulations, and keep the UAS from overhead of "non participating" humanoids.

Private "modeler" RC operations for fixed wing, glider, and Helo's are expected to follow the guidelines of the AMA. The problems are these new self stabilized gyro copter RC aircraft are often flown by amateurs who have no knowledge of the AMA, their guidelines and insurance coverage options.
