RULE FREEZE FOR THIS VOLUME
With reference to paragraph A. 12 of Volume ABR :
In all classes, the four year rule for no changes to model aircraft / space model specifications, manoeuvre schedules and
competition rules will be strictly enforced, but in step with the World Championship cycle of each category. This means
that in Volume SM changes can next be agreed at the Plenary meeting 2004 for application from January 2005.
The only exceptions allowed to the four year rule freeze are genuine and urgent safety matters, indispensable rule
clarifications and noise rulings.

GENERAL REGULATIONS AND SPECIAL RULES FOR CONTESTS, CHAMPIONSHIPS, AND
RECORDS FOR SPACE MODELS
PART ONE – GENERAL DEFINITIONS
1.1 SPACE MODEL
"Space Model" means an aero-model that ascends into the air without the use of aerodynamic lifting forces against
gravity; that is propelled by means of a space model engine; that includes a device for returning it safely to the ground
in a condition to fly again; and that is made of substantially non-metallic parts.
1.2 SPACE MODEL ENGINE
"Space model engine" means a solid propellant rocket reaction engine in which all chemical ingredients of a
combustible nature are pre-mixed and ready for use.
1.3 CLASSIFICATION OF SPACE MODELS
S1 Altitude Models
S2 Payload Models
S3 Parachute duration models
S4 Boost-glider duration models
S5 Scale-altitude models
S6 Streamer duration models
S7 Scale models
S8 Rocket glider duration models
S9 Gyrocopter duration models
S10 Flex-wing duration models
Each class, except class S7 has been subdivided related to engine size. Refer to the rules applicable to each particular
class.
PART TWO – SPACE MODEL SPECIFICTIONS
A space model must comply with the following requirements prior to launch, operation and flight.
2.1 WEIGHT
Gross or maximum weight, including space model engine or engines shall in no event exceed 0,5 kg (500 grams) except
S7 shall not exceed 1.00 kg (1000grams)
2.2 PROPELLANT
No more than 125 g of propellant materials shall be contained in its space model engine( s) at the moment of launch.
2.3 STAGES OF OPERATION
2.3. 1 There shall be no more than three (3) operable stages. A stage is defined as a portion of the model airframe containing
one or more space model engines that is designed to separate or which actually separates from the model while in flight.
An un-powered part of the model is not considered to be a stage. The configuration of a model is considered to be that
of the model at the instant of first motion on the launcher. Engines ignited simultaneously are considered one stage
regardless of the number of separated parts; for example Soyuz.

17. 12. 02 Page 8
2.3.2 Total impulse of engine( s) in a lower (booster) stage must, for safety reasons, be equal or greater than total impulse of
engine( s) in (any) of upper stage( s). The thrust of the booster stage also must be equal or greater than the thrust of each
of the upper stages. This does not relate the strapped-on boosters which are ignited simultaneously with the booster
stage.
2.4 CONSTRUCTION REQUIREMENTS
2.4.1 A space model shall be so constructed to be capable of more than a single flight and shall contain a means for retarding
its descent to the ground so that its structure may not be substantially damaged and so that no hazard is created to
persons and property on the ground.
2.4.2 A space model must not eject its engine( s) in flight unless it/ they is/ are enclosed in an airframe that will descend in
accordance with the provisions of paragraph 2.4.1. and, in the case of boost-gliders, engine casings not enclosed in an
airframe or boost-glider engine pods, must descend with a deployed streamer with dimensions no less than 25 mm by
300 mm or a parachute with an area no less than 4 dm². The engine( s) of the models cannot be fastened by flue and
cannot be an integral part of model's construction.
Tumble recovery of lower stages of multi-staged models is permitted without recovery device provided that:
1. The lower stage has three or more fins.
2. Length is no greater than 1-1/ 2 times the engine length.

necessary to maintain a substantially true and predictable flight path. If required by safety officers or judges, the builder
of the model must present data regarding the locations of the centre of gravity, centre of pressure, gross weight, burnout
weight, and/ or calculated or measured flight performance of the model.
2.4.6 A space model shall not contain any type of explosive or pyrotechnic payload.
2.4.7 Minimum gross launching weight (including engine and/ or pod) of the models which return to the ground in stable
gliding flight supported by aerodynamic lifting surfaces which sustain it against gravity (S4, S8 and S10) shall not be

being a tie for the first placer at the end of the third round.
4.3 LAUNCHING
4.3.1 Organisation
During all operations concerned with the launching and flight of space models, all authority for the safety and conduct
of operations on the flying field shall be vested in a range Safety Officer who must be a member of an FAI
Representative Aero Club and who must be 18 years of age or more. Deputy Range Safety Officers who meet the
above qualifications may have this authority delegated to them by appointment from the Range Safety Officer, but this
delegation or partial authority does not relieve the Range Safety Officer of overall responsibility and authority on the
flying field.
Adequate opportunity and facilities will be provided so that all competitors in each event at a competition may obtain
engines and prepare their models simultaneously for flight under the observation of officials.
4.3.2 Flight Permission
All space models presented for operation on the flying field shall be permitted or denied flight by the Range Safety
Officer or his duly authorised deputy on the basis of his considered judgement with respect to the possible safety of the
model in flight.
4.3.3 Launching Device
A lunching device or mechanism must be used that shall restrict the horizontal motion of the model until sufficient
flight velocity shall have been attained for reasonably safe, predictable flight. A launching angle of more than 60
degrees from the horizontal must be used.
4.3.4 Assisted Launch
A launcher must not impart to the model any velocity or change of momentum except that caused by the space model
engine( s) contained in the model. A launch assisted by mechanical devices built into the launcher shall not be allowed.
4.3.5 Launching Procedure
Launching or ignition must be conducted by remote electrical means at least five (5) metres distant from the model and
must be fully under the control of the person launching the model. The Range Safety Officer or his authorised deputy
shall possess an interlock key to the firing device that will prevent the model from being ignited and launched unless
said interlock key has been inserted into the device. Upon determining that the model may be ignited and launched in a
safe and satisfactory manner, the Range Safety Officer or his authorised deputy will insert the interlock key into the
firing device to permit ignition and launching. All persons in the vicinity of the launching must be advised that a
12
12
Page 13
14
17. 12. 02 Page 13
launching is imminent before a space model may be ignited and launched, and minimum five (5) second "count down"
must be given before ignition and launching of a space model.
4.3.6 Weather Conditions
See General Rules for International Contests, Para. B. 11.1.
4.3.7 Hazard
A space model in flight shall not create a hazard to aircraft and shall not be used as a weapon against ground or air
targets.
4.3.8 Thermal Creation and Detection
No mechanical or passive methods of thermal creation are permitted (waving jackets, spreading reflective sheets, hot air
blowers, motorcycles, etc.)
Ground or tethered thermal detection is permitted as long as it does not interfere with the conduct of the competition as
determined by the FAI Jury.
4.4 OFFICIAL ENTRIES
4.4.1 Entry
Before the first flight in any competition event, at least one model must be inspected and marked by the judges. The
next model can be inspected during the competition event. Two or more competition events may not be flown
simultaneously by the same model.
4.4.2 Model Marking and Identification
Each entry shall carry, prominently displayed upon its body, fins, or other exterior part, the competitor's FAI license
number in letters and numbers approximately one (1) centimeter high. The name, national insignia, or international
identification mark (see Section 4b, Annex 2) of the competitor's nation must be displayed on the exterior of the model.
A light coloured area of minimum dimensions 1 cm by 3 cm must be provided for the organiser's processing mark.
4.4.3 Builder of the Model
The judges shall make every reasonable effort to insure that each competitor has completely constructed the model
entered in the competition with "construction" to be interpreted as the action required to complete a model starting with
no more prefabrication than the amount used in the average kit. Models that are completely prefabricated or require
only a few minutes of unskilled effort for their completion shall be excluded from competition. Materials and design
may be obtained from any source, including kits.
4.5 OFFICIAL FLIGHTS
4.5.1 Definition of an Official Flight
A flight is considered official if the model or any part of the model leaves the launching device, loses contact with the
launching device after ignition, or becomes airborne, except in the case of a catastrophic failure according to the
provisions of Rule 4.6.3., in which case the flight is not considered official.
4.5.2 Number of flights
In each event, except Scale (S7), each competitor shall be given an opportunity to make three (3) official flights, time
and weather permitting. In Scale (S7) two (2) opportunities will be given, time and weather permitting.
4.5.3 Definition of an Unsuccessful Attempt
An attempt is classed as unsuccessful if the model or any part of the model leaves the launching device and at least one
of the following events occur:
13
13
Page 14
15
17. 12. 02 Page 14
a) model collides with another model during the flight,
b) proven frequency interference for radio controlled models,
c) catastrophic failure according to the provisions of the rule 4.6.3,
d) "no close" or "track lost" for altitude models.
If this happens on the first attempt then the competitor is entitled to the second attempt.
4.6 DISQUALIFICATION
4.6.1 Judges may disqualify any model at any time which, in their opinion, does not comply with the competition rules or
which the Range Safety Officer or his authorised deputy feels may not be reasonably safe in operation.
4.6.2 Judges may disqualify any competitor on the grounds of failure to practice or observe reasonable safety measures,
published or otherwise, for poor sportsmanship, for failure to abide by the orders of the Range Safety Officer or his
authorised deputy or for misconduct on general.
4.6.3 A model experiencing a catastrophic failure which, in the opinion of the judges, was not due to or caused by improper
design, construction, or pre-flight preparations of the model, shall not be disqualified from competition. A model
suffering such a catastrophic failure and thereby rendered incapable of additional flights may be replaced by another
model. For Scale models S5 and S7, experiencing a catastrophic failure, see rule 9.12.
4.6.4. By reason of flight characteristics, a model may be disqualified for a flight but is not necessarily disqualified for the
entire event.
4.7. RADIO CONTROLLED SPACE MODELS
4.7.1. For transmitter and frequency control see Volume ABR, Section 4b, paragraph B. 8.
4.7.2. Competitors must be called at least five minutes before they are required to occupy the starting area.
4.7.3. Once the competitor has been given permission to start, he may delay no longer than one minute before attempting
launching.
4.8. TIMING AND CLASSIFICATION
4.8.1. See Section 4b, para. B. 9.
4.8.2. The timing of flights is limited to a maximum determined by the individual class and size of engine used. The total
flight time is taken from the model's first motion on the launching device to the end of the flight.
4.8.3. The total time of the three flights of each competitor is taken for the final classification.
4.8.4. In order to decide the winner when there is a tie, additional deciding flights shall be made immediately after the last
flight of the event has been completed. The maximum time of flight in each additional round shall be increased by two
(2) minutes on the maximum time of flight of the previous round. There shall be only one attempt for each additional
flight. The times of the additional flights shall not be included in the final figures of classification for teams, they are for
the purpose of determining the winner and for awarding the prizes attached to the title. The organiser will decide the
time during which all competitors must launch their models. In the case of a tie in the team classification, the best
individual score (classification) will be used.
There shall be no more than two fly-off rounds to determine the winner. The second fly-off round will be timed to the
completion of the flight for final results.
4.8.5. For World and Continental Championships a round is defined as the amount of time allocated by the organiser for a
national team to prepare and launch their models for one official flight per team member (one hour is recommended).
4.9. ALTITUDE DATA
For measuring and calculating altitudes may be used the method based on the principles of triangulation, the method of
electronic or radar tracking or the method based on calculation of the height where the horizontal distance of tracking
lines of pairs of stations in space achieves their minimum.
14

Page 15
16
17. 12. 02 Page 15
4.9.1 Triangulation Method
4.9.1.1 Tracking
All models in any event for which an achieved altitude figure is scored shall be tracked in flight be at least tow (2)
calibrated measuring devices which are situated on a measured baseline of at least three hundred (300) metres. The
distance to the launch pad shall be a minimum of 2/ 3 (two thirds) of the current would record. rounded to the nearest
lower 100 metres.
At world championships, a redundant tracking system shall be implemented with four measuring devices (Theodolites),
two at each tracking station. The best tracking pair will be designated as the primary trackers and their data will be used
first. If the primary trackers fail, the data from the secondary trackers will be used. If they fail, the combination of
azimuth and elevation from each tracking station will be used.
For models with engines over 20 Newton-seconds the base line must be a minimum of 450 metres. The distance from
the launch site to the centre line of the base line must be 1/ 2 the base line length.
The distance to the launch pad shall be at least 300 m for models with up to 2,5 NS impulse. The launch site must be
seen from the measuring devices.
4.9.1.2 Tracking Accuracy
The measuring devices must be able to measure angles in both the horizontal (azimuth) and vertical (elevation) axes and
shall have a minimum accuracy of +/-0,5 degrees in both azimuth and elevation.
4.9.1.3 Tracking Procedure
Model for which an achieved altitude figure is required will be tracked aloft visually by measuring device operators
manning each tracking device until they see that the model has reached the maximum vertical altitude of its flight. The
angle of azimuth from the baseline and the angle of elevation from the horizontal shall then be read to the nearest
degree of arc and reported to the launching area.
Angular data thus recovered from tracking will be reduced to altitude data by use of the principles of triangulation.
4.9.1.4 Computed Altitude
The computed altitude from each station's reduced altitude data must be within ten percent (10%) of the average
altitude computed utilising data from both stations. Computed station altitudes not falling within 10% of the average
computed altitude will result in a "no close" for the model. All altitudes will be rounded-off to the nearest metre before
this "10% rule" is applied. The official scored altitude is the computed average altitude.
A "track lost" is recorded where the trackers are unable to determine the position of the model sufficiently to obtain
any angles. A zero is recorded if the flight path is erratic, unpredictable, malfunctions or is disqualified for safety reasons.
In the event of a "No Close" or a "Track Lost" for the model, the competitor may be allowed to fly again until the end
of the round. The organiser is obliged to announce altitude calculations of each flight not more than ten minutes after
the launch, to leave modelers whose flights are considered "No Close" or "Track Lost" enough time to make another
flight in the same round. A safety disqualification or a model malfunction making the model difficult to track will
result in a "zero" for the flight.
4.9.1.5 Visibility of Models
All models that are to be tracked for altitude shall disperse a coloured powder at ejection which will aid tracking.
Theodolite operators may lose track of models which do not contain sufficient powder or contain powder which does
not contrast well with the sky. The organiser will have tracking powder available for competitor's use.
4.9.2. Electronic or Radar Tracking
Altitude data derived from electronic or radar devices is valid only if evidence is presented regarding proper calibration
and correction.

9.1. DEFINITION
Scale competition is a single event and is limited to flying space models that are true scale models of existing or
historical guided missiles, rocket vehicles, or space vehicles.
9.2. MULTI-STAGE PROTOTYPE
If the entry is a scale model of a multistaged vehicle, it may be designed so that one or more of the upper stages are
inoperable dummies. However, the upper stage of a multi-staged vehicle may not be entered and flown without its
operable lower stages unless specific data is furnished to the judges to prove that the upper stage configuration was
designed to be or has flown separately, alone, and as a vehicle itself. For example, all Aerobee rockets must have
operable boosters.
9.3. SELECTION OF PROTOTYPE
The competitor must have modelled one particular serial-numbered prototype, except in the case where the prototype is
in such large mass production that there is no single individual vehicle that can be singled out for scale modelling
purposes. However, the competitor shall make every reasonable attempt to model a specific prototype.
9.4. PROOF OF SCALE
The competitor must supply scale data to substantiate his model's adherence to scale in dimension, shape, colour, and
point pattern. Minimum allowable data consists of length and diameter of the prototype and one photograph. Further
data is certainly encouraged. Dimensional data must be from an accurate source such as magazines, books,
manufacturer's specifications or data sheets, etc. Photographs from any sources are acceptable. All data presented
should apply to the particular prototype that is modelled and entered. Judges may deduct points for incorrect data.
9.5. KITS
Flying scale space model kits may be used as a source of design, materials, etc. and acceptable for entry only if
accompanied by scale substantiation data other than that contained in the kit or available from the kit manufacturer. The
competitor shall be responsible for ascertaining the correct scale qualities of the kit and must pres ent satisfactory
evidence that the kit model is correct to scale.
9.6. STABILISING FINS
Scale models of rockets, missiles or space vehicles that are not fin-stabilised may be fitted with transparent plastic fins
so as to make the model stable in flight while detracting the least from the scale qualities of the model
9.7. PLASTIC MODEL KIT PARTS
Parts from plastic model kits may be used on scale space models provided that this use is pointed out in the data
presented with the model at the time of judging for scale qualities.

17. 12. 02 Page 21
9.8. CONDITIONS OF MODEL FOR JUDGING
Models will be judged for scale qualities in flight condition minus space model motors. All clear plastid fins, launching
lugs, and fittings and other flight items must be attached to the model for scale judging. Nothing may be added to or
taken off the model between the scale judging and the flight except space model motors and recovery device packing.
9.9. MAXIMUM WEIGHT AND IMPULSE
Maximum allowable gross launching weight in limited to 1000 grams.
Maximum allowable total impulse is 160,00 Newton-seconds. Maximum engine size allowed is 80 Newton-seconds.
9.10. NUMBER OF FLIGHTS
Each entry must make a stable flight, and two (2) opportunities will be available to the competitor for this purpose, time
and weather permitting.
9.11. SCALE JUDGING
Scale quality points will be awarded to each entry according to the following schedule:
9.11.1. A competitor who presents the following proper technical data may be awarded a maximum 50 points:
– authentic, authoris ed drawing( s) of the prototype with at least ten dimensions and three cross sections, i. e. data
which define colour of cross sections and markings on it;
– workshop drawing of scale model -scale 1: 1;
– at least one colour photograph of the whole prototype with clearly visible details of colour and markings;
– at least three photographs of details and assemblies;
– file containing all necessary technical data.
9.11.2. Adherence to scale: 250 points maximum. To be considered as a scale model the dimensions of the body diameter,
overall length, overall fin span (if finless use body length) should not depart from scale by more than 10% or else the
model is disqualified. The judging category should be judged in three areas: 1) body and nose cone -125 points
maximum; 2) fins -75 points maximum; 3) colour and markings -50 points maximum. This rule shall not be applied to
dimensions less than 5 millimetres
For models with clear plastic fins see Annex 9, Cat. Scale Adherence, Sub-Cat. Fins
9.11.3. Workmanship: 350 points maximum. To be judged on neatness, care of construction, and degree of finish. The judging
category will be judged in two areas: Workmanship of nose cone, body, fins and details: 200 points maximum and
Finish of nose cone, body and fins 150 points maximum. Good workmanship that detracts from scale-such as a high
gloss finish on a model that should have a flat or dull finish -will detract from maximum points.
9.11.4. Degree of difficulty: 200 points maximum. To be judged on the degree of difficulty involved in constructing the
model. Factors to be considered include symmetry of model. number of external components, intricacy of paint pattern,
degree of detailing, and degree of difficulty in adapting the model for flight conditions.
9.11.5. Flight, characteristics: 250 points maximum. To be judged on launch, stability of flight, staging (if any), and recovery.
a competitor has to designate which operations his models are to perform in flight (e. g. separation of stages. radio
controlled trajectory, ejection of payload, etc.).
If the model has been disqualified in both official flights the competitor will not be eligible for final classification.
9.11.6. In the case of World and Continental Space Modelling Championships dimension deviations from the Scale shall be
measured by a separate qualified measuring team approved by the FAI Jury. The measured dimensions will be
presented to the Scale Judges for verification and included with the Scale Judging Data.
9.12. Should the model experience a catastrophic failure, be incapable of additional flights (4.6.3.) and have scored no Flight
Characteristic points, the competitor's static scale points will be taken to decide final classification.

PART TEN -SCALE ALTITUDE COMPETITION (CLASS S5)
10.1. DEFINITION
This series of events involves altitude competition with scale space models and is a combination of the altitude
competition (Part 5) and the scale competition (Part 9). The objective of the competition is to achieve the highest
altitude with a scale space model.
10.2. RULES
All entries must comply with the rules of Scale competition (Part Nine) and will be judged under the same rules and
receive the same number of maximum scale quality points except that three flights will be allowed and no flight
characteristics points will be given.
ALTITUDE DATA rules 4.9 will be used for this competition.
10.3. SCORING
The total number of scale quality points awarded to an entry will be added to the highest official altitude achieved by
the entry. Only in the case of "no close" or "track lost", no altitude points are added but the flight is considered
qualified and the competitor's static points will be taken to decide the final classification. Otherwise, if the model does
not make a qualified flight after three attempts, the final classification will be zero.
The entry having the largest number of total points resulting from adding the static scale quality points to the altitude in
metres achieved from the same flight, will be declared the winner. In the event of a tie, the points gained for scale
quality will be decisive.
10.4. DISQUALIFICATION
The judges must disqualify from scale altitude competition any entry which, in their opinion, does not show sufficient
scale qualities or evidence of normal level of workmanship required for a scale model under the provisions of the scale
competition (Part 9). The intent of this rule is to eliminate from scale altitude competition any entry which has scale
qualities grossly subordinated in favour of altitude performance qualities.
10.5. SUB-CLASSES

11.7.4.6. Additional points will be awarded for landing:
When the nose of the model comes to rest in the central landing area one metre in breadth, 100 points will be given. Coming to rest in one of the two outer landing areas two metres in breadth gives 50 points and 25 points will be
awarded for landing in the rest of marked landing area.
No additional points will be awarded if the landing occurs 390 seconds after the start or if the model lands out of the landing area.
For each flight, the total score is compiled by adding points for flight time and additional points for landing.
11.7.4.8. The winner of a particular flight in the relating group receives a score of 1000 points. Other competitors receive points as follows:
Pc = W C R R ´ 1000
where Pc = points of the competitor
Rw = result of the winner in the relating group
Rc = result of the competitor
11.7.4.9. The five competitors with the highest scores after three starts qualify for the final round.
There will be one final flight for a group consisting of all participants of the final round.
If there is a frequency conflict, the competitor with the worst score in three qualifying flights must change the frequency
of his radio.
11.7.4.10. The final classification will be determined by the sum of all flight scores of each competitor.
When there is a tie, the best score of one round shall be used to determine the individual winner. If a further tie occurs,
the second best score of one round shall decide the winner.
11.7.5. ORGANISATION OF STARTS
11.7.5.1. Competitors shall be combined in groups by draw in accordance with radio frequencies used to permit as many flights
simultaneously as possible. For this competition, there must be a minimum of three competitors in a group. The draw
is organised in such a way that, as far as possible, there are no competitors of the same nation in the same group. The
flying order of the different groups is also established with a d raw. A different compositionof groups shall be used for
each round.
11.7.5.2. Each group is entitled to five minutes of preparation time before the starter gives the order to count off the working
time.
11.7.5.3. Each group of competitors has 12 minutes of working time to collect transmitters from the official, perform an official
fight and return the transmitters to the official. In the case of the working time being exceeded (a delay in returning the
a transmitter to the official), the competitor will be disqualified for the round.
Note: Working time can be repeated at the Contest Director's discretion for any unforeseen reason outside the
competitor's control ( for example, radio interference). The working time shall be repeated immediately after the end of
the current round.

The purpose of this competition is to achieve the longest flight duration using an auto-rotating recovery system.
12.3. SPECIFICATIONS
12.3.1. Each entry must be decelerated during descent by its auto-rotating recovery device. The resulting autorotation must be
around the roll axis of the model, and must be the result of proper deployment and operation of the recovery system.
12.3.2. Flexible materials can only be used for covering rigid support members. The recovery system shall not be constructed
solely, or in part, of flexible materials and rigging (e. g., a parachute with rigid stringers or folding rotors of flexible
materials between rigid stringers). entries using a recovery system which is designed to act (or which actually acts) in a
manner similar to a parachute, a rigid inverted bowl, or similar techniques are specifically excluded from this
competition.
12.3.3. The entry may not separate into two or more unattached parts, and shall be disqualified if it does so.
12.3.4. The 50% requirement of Rule 2.4.3. applies.

PART THIRTEEN -FLEX WING DURATION COMPETITION (CLASS S10)
13.1. GENERAL:
13.1.1. Flex-wing (Rogallo) duration competition comprises a series of events open to any single-staged space model which
returns to the ground in stable, gliding flight supported by flexible aerodynamic lifting surfaces which sustain it against
gravity.
13.1.2. The model must utilise a vertical ballistic take-off and achieve a stable aerodynamic glide recovery without any
separation of parts or discarding of engine castings( s).
13.2. CONSTRUCTION:
The aerodynamic lifting surfaces must be constructed from flexible materials such as fabric. tissue, or plastic foil. Ribs,
spars, stringers, and the remainder of the model may be of any material in accordance with requirements of Rule 2.4.
The 50% requirement of Rule 2.4.3 applies.
13.3. DISQUALIFICATION
13.3.1. Any entry which, under any circumstances or in any manner separates into two or more unattached pieces, or discards
its engine casing( s) shall be disqualified.
13.3.2. Any entry that is supported by other than flexible aerodynamic lifting surfaces or ascends in a climb not near vertical
while under rocket power shall be disqualified from the competition.
13.3.3. Any entry that descends with parachute or streamer recovery device( s) attached shall be disqualified.
13.4. TIMING AND CLASSIFICATION
Timing and Classification Rules 4.8 will be used for this competition.
13.5. RADIO CONTROLLED FLIGHT:
The model may be radio controlled to maintain its flight path in the vicinity of the launch site. Rule 4.7 applies.

PART FOURTEEN -SPACE MODEL RECORDS
14.1. GENERAL
All FAI space model performance records, must be established in competition sanctioned by the FAI representative
National Airsports Control or its affiliate in accordance with this Sporting Code.
Established records for any class of model for which new rules or rule changes apply, such that the performance of that
class of models is affected in any way, shall be retired whenever those new rules or rule changes become effective.
14.2. SURPASSING PREVIOUS RECORD
Attempts to surpass an established record must exceed by one percent (1%) the value of the established record
performance.
All models used for establishing or surmounting of the existing record must correspond to all regulations of Part 2 of
the Sporting Code, Section 4, Volume SM.
14.3. HOMOLOGATION REQUIREMENTS
In addition to the standard FAI homologation data, the following special space model record homologation
requirements must be met by any record claimant.
14.3.1. The competition flight card of the submitted record attempt shall be marked, "Record Attempt." Tracking station
angular data must be entered in ink. The name, signature, license number and address of the record aspirant must
appear, written in ink, on the contest card. The following data, entered in ink, must also appear on the contest flight
card: competition sanction number, event in which the record attempt was flown, date of record attempt, location of
record attempt, certifying signatures of three witnessing judges, a signed statement certifying the calibration and
accuracy of the tracking system used, and a statement signed by the three judges giving the make, type and
manufacturer of the engines used in the attempt.
14.3.2. In the case of parachute/ streamer duration record attempts, the three witnessing judges must submit a signed statement
giving size, material and design of the parachute used.
14.4. HOMOLOGATION DATA
The record claimant must submit the following homologation data:
14.4.1. An accurate drawing to scale of the model used in the record attempt, said drawing to include all principal dimensions,
gross weight, and burnout weight.
14.4.2 A clear, glossy photograph enlargement of the model used in the record attempt with a ruler, hand, or other object of
known size appearing in the photograph indication size of the model.
14.4.3. The record dossier should contain the completely filled out forms as shown in tables II through V as far as applicable to
the class concerned.
14.5. JUSTIFICATION
It is the purpose of homologation procedures and requirements to ascertain as will as possible that a given model did
indeed attain the flight performance claimed and that the flight was made within the requirements and standards of this
Sporting Code. The many factors involved in the flight of a space model require that the above additional data be
submitted to conform a record attempt. In unusual circumstances, the FAI may request additional substantiating data to
insure that these purposes have been achieved.

3. GENERAL JUDGING CRITERIA:
Experience shows that often two different sets of eyes, knowing the same rules, and seeing the same occurrence will
result in two different opinions on what happened. The following section attempts to anticipate areas where different
judgements can occur and provide the definition and interpretations necessary so we can reduce potential ambiguities
on the field.
a. Who can disqualify a flight (DQ). Timers will be called upon to make decisions on flight adherence to rules and
safety. The RSO and his deputies will also judge flight safety. The Judges, the RSO and his deputies are the only person
who can declare a disqualification -not team managers, competitors or by-standers.
b. Catastrophic Failure. A catastrophic failure by nature of the name has to be obvious. You as a judge must know of
the failure when it occurs. To look later at what appears to be a normal spent casing after a flight while a competitor
argues that the delay was too long, short, or missing offers no proof to the claim of a catastrophic failure.
c. Instability. Any non-glider model that loops while coasting or thrusting in unstable. Unstable models are unsafe and
cannot be qualified. Likewise, a power pod that detaches from an otherwise true-flying model and spins about,
disqualifies the flight.
d. Unsafe Recovery. Crashes and other unsafe recoveries cannot be qualified. What constitutes an unsafe recovery?
The rules state it is one that creates a hazard to property or people. For consistency let us ask ourselves if we would like
to be under the rocket we are judging when it lands. If the answer is "no" then a disqualification is called for especially
during payload flights where no minimum size parachute is required.
e. Engine Ejection. No engines can be ejected -even if they have attached streamers or parachutes, except for boost
gliders. All engines have to descend within an airframe that provides for safe recovery. Exception: Boost glider models
may eject pods or engines if they have a streamer or parachute. (See below for minimum sizes)
4. SPECIFIC EVENTS:
a. Rocket Glider and Boost Glider.
These models must ascend in a near vertical/ non-shallow manner. Where is the cut off on a shallow ascent? Interpret
this as a qualified flight: a glider that ascends under power at an angle or more than 60 degrees from the horizontal.
Gliders also may not loop while thrusting. After burnout, during the engine coast and ejection, looping is permitted -as
long as the model does not present a safety hazard to people or property.
Rocket Gliders cannot separate into two or more pieces; boost gliders may eject an engine pod. The pod (airframe) must
descend by streamer or parachute. The minimum sizes (25 mm x 300 mm for streamer, 4 dm 2 for parachute) are
interpreted as the deployed sizes. That is, if a Boost Glider airframe's streamer does not unfurl at least 25 mm x 300
mm, then the flight cannot be qualified; 4 dm 2 area minimum deployment for a parachute is necessary for qualification.
The same applies to an ejected engine.
Gliders have to have a stable aerodynamic glide recovery. Often opinions will differ on "what is a glide." Here is how
to interpret this. The recovery has to be effected by a stable, predictable, aerodynamic glide with air passing over the
wings. The model must descend with a nearly horizontal angle of attack. When is the descent not a glide? Imagine a
pilot inside a full sized glider exhibiting the same flight characteristics as the model you are judging. Would you be
willing to trade places with the pilot? A "no" earns the flight a disqualification. Rationale: No glide is unsafe recovery.
In classes S4, S8 and S10, a flight is declared official if the model maintains a stable aerodynamic glide for at least 60
seconds, or it lands by stable flight.
b. Streamer Duration.
Streamer lengths have to be a 10: 1 ratio to widths minimum.
Rules state that a streamer has to be a single piece of flexible material. This shall be interpreted as one uncut, no joints,
homogeneous piece, not two or more pieces, joined together to form one length.
Rules state that a streamer must unfurl. This shall be interpreted to completely unfurl so that the 10: 1 length/ width ratio
is exhibited. A small ball of wadded streamer at the end of an almost completely unfurled streamer, then must disqualify
the flight.
FAI rules do not prohibit streamers that form loops or bows once fully deployed. If the wind loops a streamer fully
deployed the flight must be considered official as long as no ground hazard results.

17. 12. 02 Page 44
c. Payload Flights. See General, par. 3d. Unsafe Recovery.
d. Scale Events. : The scale judges will judge scale models for flight characteristics in accordance with Annex 9
particularly taking care of the following:
d. 1. Flight Characteristics-Staging: Stages must separate step by step. If the 3 rd stage separate s imultanously with the
2 nd stage the flight will be considered two stage only. With Saturn 1B and Soyuz if the competitor performs a powered flight of command modul, this shall be evaluated as "modeller's third stage" , according to par 2.3.1.
d. 2. Flight Characteristics -Special Effects: As Special Effects (according to the judging rules) may only emulate the
action of the prototype. Three staged rockets, like Ariane, shall not deploy nose cone cover shield and jettison a satellite during operation of the 1 st or 2 nd stage. On the contrary, with Saturn or Soyuz function of rescue system during the 1-st
stage operation is planned and possible. In case of doubt, competitor is obliged to prove reality of declared special
effect by relevant technical data. How many points award for several special effects? Compare the degree of difficulty of four booster separation to smoke before lift off!
d. 3. Flight Characteristics-Recovery: For single stage, one parachute up to 10 points will be awarded. If a single stage
rocket separates up to 20 points will be awarded. With multistage models deployment of a parachute will be awarded up
to 10 points and a deployment of a streamer 5 points. Maximum recovery points in any case may not exceed 40. To prove if the scale models to be launched are the same models which were submitted for static judging, judges will
designate each model with an appropriate marking during the static judging.
e. Parachute Duration.
Parachutes must deploy. No minimum sizes are stated. Where then is the cut off of a deployed parachute and one not
deployed? FAI rules state that at least three shroud lines make up the parachute. Broadly speaking, to deploy means to
widen. The working definition on a "deployed" parachute then will be one which exhibits at least three shroud lines and
widens out when ejected. Thus if a model descends under a crumpled wad or slender stick of parachute material, then
this is not deployment. However, if the model descends with the parachute partially open or spread out as a fan, the
flight is qualified. This un-blossomed parachute will be timed and considered an official flight. The descent must still be
safe.
The decision of the RSO of his deputies on matters of safely take priority.
5. ORGANIZERS TASKS:
a. Scale Events -The organiser of an international contest shall appoint three scale judges from the nomination list of
Space Models FAI Judges. In case of World or Continental Championships, there will be appointed five FAI judges and
one reserve judge of different nationalities, including the Chief Scale Judge. Their names will be submitted to the
CIAM or CIAM Bureau for approval. The Chief Scale Judge may not be from the organising NAC. He shall organise
work of the judging panel and shall represent it. An extra judge (who may be the reserve judge) shall be appointed as
the chief of the dimension measuring team.
The organiser shall also provide an adequate area for relevant number of entries with bright overhead lights and with
tables for turn in, static judging and dimension measuring. The static judging area will be equipped with dimension
measuring devices and a PC with a qualified operator. Access to the static judging area during static judging will be
restricted to all persons except for static judges, dimension measuring team, PC operator, contest director and FAI Jury.
b. Altitude Events -Organiser of an international altitude event must provide altitude measuring devices in
compliance with the rule 4.9.1.2. and qualified personell for altitude measuring. He also must provide
radiocommunications between tracking stations, RSO and the computer center in the field. Altitude measuring team
shall do test tracking on duration and/ or scale models on the day preceding the competition day( s) for altitude events to
check tracking and data reduction systems. The head of the altitude measuring team shall present test altitude measuring
results to the Jury to prove altitude measuring team readiness and necessary accuracy of measurements and get
Juryapproval, before the official flights begin in an altitude event.
c. Range Safety Officer (RSO) -Organiser of an international contest will appoint a person to act as Range Safety
Officer (RSO) from the FAI nomination list of judges – specialized in spacemodelling. He may appoint other qualified
persons to act as his deputies in accordance to the provisions of the rule 4.3. In case of World or Continental
Championships, organiser of the contest shall submit name of RSO to CIAM or CIAM Bureau for approval. RSO may
not be from the organising NAC. When the there are junior and senior classifications at the same place and at the same
time organiser shall appoint two RSOs one for senior and the other for junior classification. They shall be not of the
same nationality but shall have one language in common.

2. Competitors
All competitors in the specified open international contests are eligible for the World Cup.
3. Contests
Contests included in the World Cup must appear on the FAI Contest Calendar and be run according to the FAI Sporting
Code. The contests to be counted for a World Cup in one year are to be nominated at the CIAM Bureau Meeting at the
end of the preceding year and are to be indicated on the FAI Contest Calendar.
4. Points Allocation
For S4B, S6B and S9B :
Points are to be allocated to competitors at each contest according to their placing and results as given in the following
formula below :
B = 10 log( ´100 ÷ ø ö -+ ç è æ ´ log(N) A) Max X K
where: B = points awarded to the competitor
X = competitors score
Max = 3 x 240 = 720 – total maximum flight time points for three flights in a class,
A = number of competitors
N = placing of competitor.
For S7 and S8E/ P
B = 10 ) log( ÷´100 ø ö + ç è æ ´ -log(N A) Y X K
where: B = points awarded to the competitor
X = competitors score
Y = winners score
A = number of competitors
N = placing of competitor.
For all classes
Points are awarded only to competitors completing at least one flight in the contest.
In the event of a tie for any placing, all competitors with that placingreceive the number of points appropriate to that
placing, rounding up the score to the nearest whole number of points
5. Classification
The World Cup results are determined by considering the total number of points obtained by each competitor in the
World Cup events. Each competitor may count the result of all competitions, except that only one competition may be
counted from each country in Europe (taking the better score for any European country in which he has scored in two
competitions). To determine the total score, up to three events may be counted, selecting each competitor's best results
during the year.
In the event of a tie the winner will be determined according to the following scheme. The number of events counted
will be increased from three, one at a time, until the winner is obtained. If this does not separate the tied competitors
45
45
Page 46
47
17. 12. 02 Page 46
then the winner will be determined by considering the points obtained in the best three events multiplied by the number
of competitors flying in each event. The winner is the one with the greatest total thus calculated.
6. Awards
The winners earn the title of Winner of the World Cup. Certificates, medals or trophies may be awarded by the
Subcommittee as available.
7. Organisation
The Subcommittee shall be responsible for organising the World Cup and may nominate a responsible person or a
special subcommittee to administer the event.
8. Communications
The Chairman of the Space Model Subcommittee should receive the results of each contest in the World Cup and then
calculate and publish the current World Cup positions. These should be distributed to the news agencies and should
also be available to any interested bodies or individuals. Latest results will also be sent to the organiser of each
competition in the World Cup for display at the competition. Final results of the World Cup are sent to the FAI,
National Airsports Controls and modelling press. Each World Cup Contest Organizer is obliged to send results of his
contest to the Chairman of the Space Models Subcommittee and to another person (if nominated) responsible to
administer, the event within three days after the contest has ended. The current World Cup position will be calculated and distributed within the next seven days.
9. Jury
A jury of three responsible people shall be nominated by the CIAM Space Modelling Subcommittee to rule on any
protest concerning the World Cup during the year. Any protest must be submitted in writing to the Space Model
Subcommittee Chairman and must be accompanied by a fee of CHF 80. In the event of the Jury upholding the protest,
the fee will be returned.

resembling the prototype, of rocketplanes or future (futuristic) starship (S-F) past or present. The objective is to build a
model of a Rocketplane/ Starship and fly it by radio control. Rule 4.7. applies.
11.8.2. Choice of the Model:
The competitor must have produced a genuine rocketplane or spaceship (futuristic or not). However, the competitor
shall do his best to reproduce a model from an original subject.
There are two possible subclasses to be chosen:
l rocket powered aircraft S11/ P (R)
l spaceships (futuristic or not) S11/ P (S)
11.8.2.1. Maximum Weight and Thrust:
Maximum weight (at take -off) ...................................... 1000 g
Maximum total impulse................................................... 160 Newton seconds
Engines up to 80 Ns are allowed.
11.8.3. Spaceship with Several Stages:
If the entry is a scale model of a multi-stage vehicle, it may be designed so that one or more of the upper stages are
inoperable dummies. However, the upper stage of a multi-staged vehicle may not be entered and flown without its
operable lower stages unless specific data is furnished to the judges to prove that the upper stage configuration was
designed to be or has been flown separately, alone and as a vehicle itself.
A futuristic spaceship can have several stages. The last stage must be radio-controlled.
11.8.4. Stabilisation Flaps:
The rocketplane model (or starship) should have the functional radio-controlled control surfaces of the real craft.
11.8.5. Kit of Plastic Parts:
Parts from plastic model kits cannot be used.
11.8.6. Introduction of the Model for Judging:
Models will be judged for scale qualities in flight condition minus space model motors. All clear plastic fins, launching
lugs and fittings and other flight items must be attached to the model for scale judging. Nothing may be added to or taken off the model between the scale judging and the flight except space model motors and recovery device packing.
11.8.7. Number of Flights:
Each model must make one stable flight. Two attempts will be accorded to the competitor, time and weather
permitting.
11.8.8. Judging of the Model:
The models will be judged according to the following rules:
