Model Helicopter
Safety Rules (Abridged)
Issue 1 2006 (amended)
Note: These rules are model helicopter specific and are to be used as a supplement to the
SAMAA National Safety Rules abridged parts 1 and 2 and the SAMAA National Safety
Code. In no way does it give a helicopter pilot permission to ignore the SAMAA Code.
1. Reserving your frequency is mandatory before switching on your transmitter.
2. A safety officer will be appointed at all helicopter flying events.
3. Only pilots actually flying and their instructor or observer may be in the flight area.
4. The use of an observer is strongly recommended, especially if two or more helicopters
are flying simultaneously.
5. Pilots shall keep a safe distance between their helicopters and all people at the flying
site, including themselves. These distances shall be;
5.1The pilot shall stand a minimum of 5 meters from a helicopter that is hovering.
The pilot shall stand a minimum of 10 meters from the helicopter, if a learner or
pupil pilot is flying.
The pilot and Judges shall remain a minimum of 9 meters from a flying helicopter,
when participating in a Competition.
A minimum of 30 meters if spectators are present or the helicopter is
participating in a Event, Airshow or Display.
6. Never under any circumstances fly the helicopter between yourself, the spectators,
other pilots or the pit area.
7. Pilots shall enquire about and adhere to all rules applicable at the flying site and keep
their model helicopters within the established flight boundaries of the flying site. There
shall be a minimum distance of 30m between the established flight line and any
8. Always ensure that the control surfaces are working in the correct direction before
starting your helicopter especially after any work has been carried out or radio adjustments
have been made. eg. -Aileron's, elevator, rudder, throttle and gyro.

9. If using a PCM receiver ensure that the failsafe function is set to at least reduce the
throttle to the low rpm position or to cut the engine completely. The other controls are
recommended to be set to the 'hold' setting.
10. Always ensure that the throttle is set to idle and any flight mode switches are set to
NORMAL / HOVER mode before attempting to start the motor.
11. When starting the heli always ensure that the rotor head is held firmly. Never release
this until you are ready to take off from the appropriate area.
12. Do not hover directly in front of other pilots. This is to ensure that they will have a clear
view of their own models.
13. Ensure that the blades are securely tightened within the grips. This can be checked by
holding the helicopter sideways with the blades opened; a gentle shake of the helicopter
should make the blades fall under their own weight. This can help eliminate boom strikes.
14. Ensure that the batteries have sufficient charge before making the flight. Note: -It is
advisable to fit a battery monitor.
15. Regularly range test the model and look for any servo glitching and if unsure then do
not fly. All new and rebuilt models must undergo range checks prior to flight. When an
'engine running' range test is performed, ensure the model is held firmly by the rotor head
and that your helper can kill the engine via an alternative method. i.e.: disconnecting the
fuel line or turning the ignition switch off etc.
16. Never spin the blades under power whilst in the pit area.
17. With electric helicopters, the main battery power to the speed control may only be
connected in the take off area when the pilot is ready to spin up and start flying. The power
will similarly be disconnected immediately after the flight and before the Helicopter is
returned to the pits.
18. Never leave a helicopter running unsupervised under any circumstances.
19. All models shall be airworthy. The pilot is responsible for the pre-flight inspection
before each session.
20. New and rebuilt helicopters must undergo a thorough inspection by the club safety
officer or in his absence the most experienced person available. This inspection should
preferably not be done by the builder.
21. Regularly check that all servos are not under excess load. This can be done by
removing the link from the servo and attempting to move the linkage by hand. This will
indicate if there are any stiff spots in the system. While the link is removed from the servo,
also check that the servo does not move more than the maximum limits of the control.
Note: -This check should be carried out in the workshop.

22. Regularly check for worn or damaged control linkages and chipped or damaged rotor
and tail blades.
23. When flying your helicopter with fixed wing aircraft present it is advisable to comply
with the following general guide lines.
At many fields, helicopters are only permitted to take off and land from the
designated helicopter area(s).
Helicopters are not allowed to fly in a manner that interferes with other aircraft
Only proficient helicopter pilots may join the fixed wing circuit and only if they
maintain forward flying speed in the same direction as the other aircraft.
The hovering of helicopters over the runway or in the flying circuit of the other
aircraft is forbidden.
Due care and consideration should be observed when fun fly, 3D type or park
flyers are flying.
It is advisable after announcing your intentions to land, to land, and there after
to state "helicopter "on" or "off" runway, taxiways or the designated helicopter
area. This is to avoid a situation where an aircraft needs to land (due to a dead
motor etc.) and a helicopter has landed on the runway and its rotors are
spooling down and the helicopter pilot is unable to move his helicopter from
the runway.
Note; The present legal maximum allowable all up weight of a model helicopter, is
limited to 6,5 Kgs. At the request of the Helicopter Sig a procedure is presently
being prepared, which will permit, under controlled and specified conditions, larger
proven helicopters, and suitably qualified pilots, to fly in the RSA.
This procedure when completed will be submitted to RAASA for acceptance, and
following this acceptance, SAMAA will have the Insurance policy extended to legally
permit the flying of these larger models.
Set out below are some of the conditions which will need to be observed by pilots
flying these larger helicopters;
Large helicopters (>1,8m rotor diameter) must always be flown with an observer
Large helicopters and Turbine powered helicopters must be fitted with a radio
controlled method to kill the motor, other than the throttle, i.e.: an electronic kill
switch or a fuel cut-off.
Large helicopters will be inspected during construction and test flown after
certification by an experienced and competent pilot.

28 Turbine powered helicopters, will have the required helpers, and equipment
present, before starting takes place. The helicopter must be well away from
spectators and other pilots, and in an area that has the minimum fire risk.
29 Turbine powered helicopter pilots must, in addition to the SAMAA and MHSA safety
rules, adhere to all relevant safety rules of the South African Model Jet Association
(SAMJA). This is to ensure the safe integration of a turbine motor into a helicopter.

1.2 Radio Control
When operating any radio control model aircraft, SAMAA members and other
pilots shall comply with the following:
I shall complete a successful radio equipment ground range check
before the first flight of the day.
I shall not fly my model aircraft in the presence of spectators until I
become a qualified flier, unless accompanied, and under the
instruction of an experienced R/C pilot.
I shall perform my initial turn after take-off, away from the pilots,
spectators, club House and parking area, and I shall not thereafter
intentionally fly over the pit area, spectator area, or parking area.
I shall not fly my model aircraft on the pilot station side (pit side) of the
flight line (the flight line is defined as a line a minimum of 7 metres
away from the pilot stations and parallel to the near side of the runway
in use).
I shall not deliberately fly a model aircraft without visual contact (i.e.
model aircraft to be kept within line of sight of the R/C pilot at all
I shall not knowingly operate an R/C system within 5km of another
R/C flying site.
I shall operate my model aircraft using only the ICASA and SAMAA
approved and published/gazetted radio control frequencies.
I shall not switch on or allow my transmitter to be switched on without
first checking the availability and reserving the frequency I intend to
use, with my membership card.
I shall not fly my model aircraft higher than approximately 400ft (120
metres) above ground level within 5NM, or within the CTR (control
zone) of an airport, without obtaining written permission from the air
traffic control authority at that airport.
I shall give the right of way to all full size or manned aircraft at all
times, and take the necessary avoiding action, when any full size or
piloted aircraft are in the proximity of my model flying activity.
I shall obey the Rules and Guidelines set out in the SAMAA Operation
Manual and Safety Code if no other code or rules are available at the
flying site I am using.
Specific Rules
Any model flying club or field located, within five nautical miles of an existing
full size airfield or aerodrome, or within the CTR ( controlled airspace), or
under the TMA of a manned Airport, is required to have contacted that Airport
and established the protocols under which the Club or field may operate. The

Page 3
initial contact will be established by SAMAA, after which the Club or users of
the field, must maintain regular contact in future.
The organisers of any public display, Airshow, Competition or similar event,
where spectators will be present, or where CAA Regulations need temporary
relaxation shall submit an " Application for a Permit to Conduct an Event" in
writing to the General Manager for approval at least 60 days before the event.
These applications must contain information relevant to event, such as
location, field layout, crowd control measures, frequency control system,
name of proposed safety officer or display/events director, names of pilots
who will be flying, together with their proficiency and any other or information
which could affect the safety of the public, as well as details of any temporary
relaxation or exemption required from the CAA for the Event..
The written Approval from the SAMAA, which may contain additional
conditions which must be complied with by the organisers, is required by the
organiser before the event may proceed.
All SAMAA Registered Clubs or flying fields shall produce their own set of
Field Safety Rules and Regulations. These rules shall, as a minimum,
contain the SAMAA Safety Code and Field
Operation criteria, as well as safety conditions applicable to their field. Further
these Club or field Rules shall reference the SAMAA Operations Manual. The
club shall be responsible for the enforcement of these rules and provisions
and shall be fully responsible for the safety of all members and spectators at
their field.
3D aerobatic aircraft and electric aircraft will comply with all model aircraft
safety rules and will fly within the approved circuit at a flying field.
At the discretion of club management, helicopters should be allowed to fly in
a circuit with fixed wing model aircraft, provided that the helicopter is flown by
a proficient pilot in a manner which does not interfere with the other model
aircraft flying in the circuit.
No pilot of a model aircraft, helicopter, 3D model, Fun Fly and park flyer is
permitted to:
(a) Fly his aircraft in the opposite direction to model aircraft in the circuit.
(b) Hover
his aircraft over the runway or in the circuit if other model
aircraft are flying.
(c) Do "shoot ups" over a runway.
Remember that these are the "Abridged Safety Rules" and the more
detailed rules and guidelines will be found in section 6.A.3 "The National
Safety Codes" in the SAMAA Operations Manual.
Additional rules, as found necessary, will be approved by the
appropriate SAMAA Committee and added to this Safety Code.

Page 4
(PART 2)
This code is endorsed by SAMAA, and should be included in each and every
SAMAA-registered model flying club's operations and safety requirements, as a
minimum requirement.
Under normal operating circumstances, there shall be no more than five (5)
model aircraft/helicopters airborne at any one time on a single flight line at any
field, unless specified under competition rules, special events, or authorised
by the club management.
Frequencies used shall be the ICASA/SAMAA approved frequencies. These
frequencies shall be controlled by a positive means, usually by the use of a
frequency board displaying approved frequencies and using the SAMAA
frequency system of "card on" is the mandatory minimum.
Radio transmitters not in use at a flying field shall be switched off and placed
in a transmitter pound.
A pilot intending to fly must first ensure that his transmitter frequency is not in
use, then reserve the frequency with his card or marker, before switching on
his transmitter.
Pilots should be qualified by an acceptable training program and the "SAMAA
Solo" is the minimum acceptable qualification for a pilot to be allowed to fly
unattended, by a instructor, when other pilots are present on the flightline.
Instructors shall be competent R/C model fliers who shall not only provide
adequate instruction, but also consistently demonstrate safety by their
example and attitude.
Strict announcement procedure by pilots must be normal operation where
pilots on the flight line call out to other pilots any intention to land, take-off,
move onto or cross the active runway. "Dead stick" situations take priority
over other operations.
Any guest or club visitor who is allowed flight privileges at any field, must be
suitably qualified and must be prepared to submit his model aircraft for an air
safety/airworthiness inspection, before being allowed to operate his aircraft
without supervision.
For insurance, CAA, and SAMAA compliance, any club organising a public
display, airshow, or Event, where the public will be present, shall submit an
"Application for a Permit to hold an Event" form to the General Manager for
approval. The written approval for the event may contain conditions which
need to be in place before the event may proceed.
j) Clubs and flying fields must clearly define the fly zones for their respective
fields, these shall be a minimum of 30 meters , in the case of smaller aircraft

Page 5
and 50 meters in the case of large scale or Turbine Jet aircraft, from
spectators, except in the case of takeoff and landing where 30 meters will be
allowed. They must further clearly define the flightline for each runway, and
the limit of the area in which model aircraft may operate when flying from that
Every SAMAA member is responsible for safety, and making sure the club
rules, the SAMAA rules, and regulations are observed, and shall ensure that
all model aircraft operations are conducted in the safest manner possible.
Club members who refuse to abide by club rules and regulations, and who
disregard instructions about safety, should be given a formal warning, and
should they still not comply, should have their flying privileges revoked.
Individual pilot station locations should be marked. Pilots must control their
model aircraft from these locations; but take-off and landing may be done from
nearer the runway itself, provided that all other pilots are informed of this
impending event.
Spectators, visitors and non essential Club members, are not allowed near the
flightline and pilot station locations, except in the case of spotters, callers,
instructors or authorised persons, whose presence is required.
A safety barrier or fence must be in place to prevent non-airborne model
aircraft that are out of control, from entering the, parking or spectator areas.
This fence should be a minimum of 30m from the flight line. A low fence
around or in front on the pilot stations, to protect the pilots flying is
All Clubs should have an aircraft check program so that all new model aircraft
are inspected prior to operation, particularly those belonging to beginners. A
re-certification program after major repairs and/or rebuilding of an aircraft is
Only one runway may be used at a time, all take-offs and landings shall take
place on the runway, into wind if possible, and take-offs shall commence from
directly in front of, or opposite the pilot stations. Pilot stations shall be used by
pilots when flying. If by common consent the runway is to be changed, due to
wind direction change, all pilots will move to the selected runway.
Where a flying site layout allows the operation of two independent runways
and flight lines simultaneously, the use of two flight lines, ie for competition
must have the approval of the
s) Contest director, or authorised Club official. These flight lines and runways
must not intersect and must be separated by at least 60 metres.
When flying electric powered model aircraft, the main power to the motor shall
only be connected when the model is in the starting box or on the flightline,
immediately before the pilot starts his flight. Similarly the power will be
disconnected before the model is taken back to the pits.

Page 6
As the threat to the future of Clubs flying model aircraft powered by glow or
gas engines has increased and become real in the last few years, it is now a
requirement that efficient silencers are fitted to all internal combustion
engines, and that the noise restriction on these model is observed.
In the interest of Safety, all large models will be restrained, either by a helper
or by other means so as not to be a danger to other persons present while
starting the engine..
Turbine powered models, will be started away from other aircraft and persons
in the pits and shall not be started unless the required safety personnel are
Large model aircraft or special aircraft over 25 Kgs will require a "permit" to
fly" following inspection and certification as set out in the SAMAA manual of
Operations before being allowed to fly at any SAMAA registered field.
Note; These are the National Model Aircraft Safety Abridged rules, other
applicable rules which are to be observed are the Helicopter, Glider and SIG Rules
and the SAMAA National Safety Code as contained in the SAMAA operations
