So what are FARs cover R/C aircraft (is there a weight or size threshold)?

The FAA accepts the Academy of Model Aeronautics definition of a recreational
model as weighing 55 lbs (dry, I think) and operating under 400' altitude
(a provision busted every day by all kinds of RC aircraft).

SUBJ: INQUIRIES RELATED TO UNMANNED AEROSPACE VEHICLE OPERATIONS

NOTE: This notice does not apply to the recreational, noncommercial use of model
aircraft. It is not intended to inhibit or restrict the routine operation of
model aircraft for recreational purposes. (The Academy of Model Aeronautics, in
part, defines model aircraft as weighing less than 55 pounds and being
operated below 400 feet above ground level.) Additional guidance for the
operation of these aircraft is provided in Advisory Circular AC 91-57, Model
Aircraft Operating Standards, dated June 9, 1981.

http://www.eoss.org/faa/AFS_400_UAS_POLICY_05_01.pdf

"AFS-400 UAS POLICY 05-01
TITLE: Unmanned Aircraft Systems Operations in the U. S. National Airspace
System - Interim Operational Approval Guidance
DATE: September 16, 2005
1. Purpose: AFS-400 UAS Policy 05-01 provides guidance to be used to determine
if unmanned aircraft systems (UAS) may be allowed to conduct flight operations
in the U. S. National Airspace System (NAS). AFS-400 personnel will use this
policy guidance when evaluating each application for a Certificate of Waiver or
Authorization (COA). Due to the rapid evolution of UAS technology, this policy
will be subject to continuous review and updated when appropriate."

The police officer probably ran afoul of this provision:

"6.11. Flight Over Congested or Populated Areas. If flight over congested areas,
heavily trafficked roads, or an open-air assembly of persons is required, the
applicant must provide information that clearly establishes that the risk of
injury to persons on the ground is highly unlikely."


Both documents refer back to a 1981 advisory circular under which the
Academy of Model Aeronautics has been operating:

http://www.eoss.org/faa/ac91-57.pdf

"1. PURPOSE. This advisory circular outlines, and encourages voluntary
compliance with, safety standards for model aircraft operators.

"2. BACKGROUND. Modelers, generally, are concerned about safety and do exercise
good judgement when flying model aircraft. However, model.aircraft can
at times pose a hazard to full-scale aircraft in flight and to personsand
property on the surface. Compliance with the following standards will help
reduce the potential for that hazard and create a good neighbor environment
with affected communities and airspace users.

"3. OPERATING STANDARDS.

"a. Select an operating site that is of sufficient distance from populated
areas. The selected site should be away from noise sensitive areas such as
parks, schools, hospitals, churches, etc.

"b. Do not operate model aircraft in the presence of spectators until the
aircraft is successfully flight tested and proven airworthy.

"c. Do not fly model aircraft higher than 400 feet above the surface.
When flying aircraft within 3 miles of an airport, notify the airport operator,
or when an air traffic facility is located at the airport, notify the control
tower, or flight service station.

"d. Give right of way to, and avoid flying in the proximity of, full-scale
aircraft. Use observers to help if possible.

"e. Do not hesitate to ask for assistance from any airport traffic control
concerning compliance with these standards."

RC aircraft have been grounded by the FAA at various times under
SFARS or NOTAMS for security purposes--during the Utah Olympics,
when a major politico is attending an outdoor event. etc.

I've been flying RC models for about 11 years:
