My calender says that BOTH are law now, passed and signed. My calender says AMA limits FPV to LOS and flying beyond LOS then subjects you to 14.91.119(c) just as any other aircraft.
There is nothing in that law that says models or any type of RPVmust comply with FAR part 81. It says that the FAA must write regulations that incorporate the requirements of that law and implement them by September 2015. Nothing in that law is required to be followed till that is done.
