equipment on Amateur Band frequencies.)
5) Flying sites separated by three miles or more are
considered safe from site-to site interference, even
when both sites use the same frequencies. Any
circumstances under three miles separation require
a frequency management arrangement, which may
be either an allocation of specific frequencies for
each site or testing to determine that freedom from
interference exists. Allocation plans or interference
test reports shall be signed by the parties involved
and provided to AMA Headquarters. Documents of
agreement and reports may exist between (1) two or
more AMA Chartered Clubs, (2) AMA clubs and
individual AMA members not associated with AMA
Clubs, or (3) two or more individual AMA members.
6) For Combat, distance between combat
engagement line and spectator line will be 500 feet
per cubic inch of engine displacement. (Example:
.40 engine = 200 feet.); electric motors will be
based on equivalent combustion engine size.
Additional safety requirements will be per the RC
Combat section of the current Competition
Regulations.
7) At air shows or model flying demonstrations, a
single straight line must be established, one side of
which is for flying, with the other side for spectators.
8) With the exception of events flown under AMA
Competition rules, after launch, except for pilots or
helpers being used, no powered model may be
flown closer than 25 feet to any person.

9) Under no circumstances may a pilot or other
person touch a powered model in flight.
Organized RC Racing Event
10) An RC racing event, whether or not an AMA Rule
Book event, is one in which model aircraft compete
in flight over a prescribed course with the objective
of finishing the course faster to determine the
winner.
A. In every organized racing event in which
contestants, callers and officials are on the course:
1. All officials, callers and contestants must properly
wear helmets, which are OSHA, DOT, ANSI, SNELL or
NOCSAE approved or comparable standard while on
the racecourse.
2. All officials will be off the course except for the
starter and their assistant.
3."On the course" is defined to mean any area
beyond the pilot/staging area where actual flying
takes place.
B. I will not fly my model aircraft in any organized
racing event which does not comply with paragraph
A above or which allows models over 20 pounds
unless that competition event is AMA sanctioned.
C. Distance from the pylon to the nearest spectator
(line) will be in accordance with the current
Competition Regulations under the RC Pylon Racing
section for the specific event pending two or three
pylon course layout.
11) RC night flying is limited to low-performance
models (less than 100 mph). The models must be
equipped with a lighting system that clearly defines
the aircraft's attitude at all times.
