3) At all flying sites a straight or curved line(s) must 

be established in front of which all flying takes place 

with the other side for spectators. Only personnel 

involved with flying the aircraft are allowed at or in 

front of the flight line. Intentional flying behind the 

flight line is prohibited.
4) I will operate my model using only radio control 

frequencies currently allowed by the Federal 

Communications Commission. (Only properly licensed 

Amateurs are authorized to operate 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.
