4. SPORTING CODE PROPOSALS
Secretary's Notes. The latest issue of Section 4 of the Sporting Code does not carry page numbers. Reference will
therefore be made only to paragraph numbers.
Words proposed to be deleted are shown struck through. New wording is shown in italics.
A) SECTION 4a - CIAM INTERNAL REGULATIONS
a) Paragraph A12, Effective Date of Rule Changes - United States of America (USA).
For all classes, rule changes from the current Sporting Code will become effective only when the
following Sporting Code is issued. The only exceptions will be for real safety matters and for absolutely
indispensable rule clarifications; also changes affecting noise. Changes to model specifications involving
model size and/or power limits and the introduction of new manoeuvre schedules shall receive separate
consideration in each case, allowing for World Championship schedules. These rule changes should
become effective the first of a non-world championship year for the event(s) affected.
The guideline to be applied for proposed exceptions is whether necessity is involved rather than
desirability or mere rule improvement. Technical rule changes affecting model, engine or equipment for
flying must be accompanied by supporting data.
Each proposal submitted for change to the Sporting Code shall contain an effective date for the
implementation of the proposal.
Within seven weeks after the Plenary meeting, the FAI will submit an Amendment List with accepted
proposals
B. SECTION 4b - GENERAL RULES FOR INTERNATIONAL CONTESTS
a) B.2.3. Continental Championships - Bureau. Amend to read:
These are limited international contests in which the competitors are nominated by their NAC and are
persons or teams from at least [three] four different nations from one continent. These contests are for
individual and possibly team classification and should be organised only in the years when there is no
world championship in the particular class.
Reason. To align with the General Section of the Sporting Code (Paragraph 3.5.3.)
b) B. 3.2. Sporting Licence - Bureau. Amend to read:
Every competitor and team manager entering an international contest must possess a Sporting Licence of
the FAI. This Sporting Licence is issued by the NAC of the competitor or team manager under the
conditions of the General Section of the Sporting Code and must bear the national identification mark.
Reason: To permit some form of sanction action to be taken against a team manager acting in an
unsportsmanlike way.
c) B.3.4 Age Classification of the Contest. - Russia Amend the first sentence as follows:
A competitor is considered to be a junior up to and including the calendar year in which he attains the
age of 18 21 . All other competitors are classed as Seniors.
Reason: Expansion of the age for juniors up to 21 will have a favourable effect on increasing the number
of countries/entrants for World and European Championships. Besides. it will allow to train juniors as a
reserve contingent for senior national teams on a regular basis. Competition organisers experience
(according to the statistics) some difficulties in recognising Junior Championships as such. In the
majority of sports disciplines, including aeromodelling, the age for juniors is 21 years.
d) B.3.5. National Teams for World and Continental Championships - Control line Subcommittee. Amend
to read:
A national team shall consist of three individual competitors, or three pairs of competitors for each
category as a maximum, and a Team Manager. For control line (F2) only, the team may consist of four
individual competitors or four pairs of competitors for each category as a maximum provided that the
fourth competitor is/are junior(s), plus a Team Manager. The reigning World or Continental Champion
would have the right (subject to the approval of his National Airsports Control) to participate in the next
world or continental championships in that category regardless of whether he qualifies for the national
team or not. If he is not a member of the national team, his score will not be considered in the team
results.
Reason: See 4.B.g) below.
e) B.9.1. (Timing) - Russia. Amend to read:
Each team shall have the right to must provide a timekeeper for the following classes of world and
continental championships: F1A, F1B, F1C, F1D, F1E, S3, S4, S6, S8, S9, S10; with the organiser to be
responsible for providing lodging and food only. If there is no timekeeper, then there is no team for a
World or Continental Championships. Teams should nominate only skilled timekeepers and the
timekeepers should bring binoculars, watches and tripods for their own use. The organiser must use these
provided timekeepers as a priority, before allocating duties to national or other timekeepers.
Competitors can act as timekeepers.
Reason: Now not every team has a timekeeper. For example, at the last European Championships, 1998 in
Portugal, most of the timekeepers were young boys and girls from Portugal. Sometimes, they could not
see the models. S Makarov (F1A, Russia) in the 6th round had zero time but his timekeepers wrote 3
minutes. S Makariov told the jury member P Chaussebourg that he had not had a max in the round and
repeated an attempt. The same thing happened with V Stamov in the 5th round. In both cases, the
timekeepers were from Portugal although at different positions on the starting line. At approximately
half of the starting positions, there were only young Portugese timekeepers.
f) B.12.1. Classification and Awards at World Championships - Control line Sub committee.
l earn the title of Junior World Champion in the category.
* See Agenda Item 4.b.a) above.
Reason: See 4.B.g)
g) B.12.2. International Team Classification - Control line Sub committee. Amend sub paragraph B.12.2a):
a) The international team classification is established by taking the total scores of the three members,
(in the case of control line, the three best scoring members) of the team together. In the case of a
team tie, the team with the lower sum of place numbers, given in order from the top, wins. If still
equal, the best individual placing decides.
Reason: The issue of clarification of junior participation as a team member of F2 teams at Continental
and World Championships is not a matter for proposal but one for proper wording of the amendment
adopted previously. As minuted in the 1995 Bureau Minutes (page 5, item 9) the President noted that the
decision to adopt the original French proposal had ben taken at the 1993 Plenary but the implementation
at the 1994 WC in China was flawed. A better wording was requested of the technical meeting ad
committee. Further requests came from the Sub committee Chair who indicated at the 1996 Fall Bureau
meeting that the system worked well at the 1996 F2 World Championships in Sweden and recommended
continuation for at least two more World Championships. The changes proposed are in response to the
requests of the President and the Plenary.
C. SECTION 4c - AEROMODELS
C1 PART ONE - GENERAL REGULATIONS FOR AEROMODELS
a) 1.1. General Definition of Aeromodels - Bureau. Amend to read:
An aeromodel is a heavier-than-air craft of limited dimensions, with or without engine, not able to carry a
human being and to be used for competition, sport or recreational purposes rather than unmanned
aeronautical vehicles (UAV) developed for commercial or governmental scientific research or military
purposes..
Reason: With the understanding that the FAI is creating a commission for UAVs, it should be noted that
the lines which separate the recreational model from the unmanned research/scientific/military vehicle
have become blurred. This is due largely to the increased size of aeromodels. The added text supplies a
clearer definition of an aeromodel as opposed to a UAV.
b) 1.2 General Characteristics for Aeromodels
i) Bureau. Amend the first sentence:
Unless otherwise stated, aeromodels shall meet the following general specifications *:
* See Section 4c, Part 7 - Records for specifications concerning aeromodelling records.
ii) Belgium. Amend the paragraphs about noise limits as follows:
Noise limits shall be applied apply to all aeromodelling engine categories, effective January 1, 1991; with
96 dB(A) at 3 metres for any category which does not have approval for any other noise rule. Specific
noise measuring procedures are to be developed by each subcommittee for its category.
Noise limits do not apply to models with electric motors.
Noise limits apply to all aeromodelling categories. Limit per model is 96 dB (A) at 3 metres when
measured over concrete or 94 dB (A) when measured over short grass. Further noise reduction may be
imposed in category-specific rule sets. Unless otherwise specified, noise measuring procedure must
comply with the procedure delineated in rule 5.1.2 of the present sporting code.
Reason: Clarification. Worldwide, noise reductions on air traffic are enforced. The FAI recommended
overall noise reductions for all air sports during the general conference of 1997. The present rule in
section 4 of the sporting code failed to impose significant noise reduction for most categories - no
significant effort was made in F1C, F2A, F2C, F2D, F3C and F4.
This proposal intends to impose a blanket noise reduction for all aeromodels that should prevent any
combustion engine being used without an efficient noise muffler. The intent of the rule as it was written
in the early 1990s was exactly as stated here. Sadly, it was bypassed by some subcommittees who
obtained derogations (F1C, F2A) arguing about a limited time of a motor run. For other categories, fake
silencers were introduced in the definition of the models (F2D, F3C) based on physical dimension, not on
effective noise reduction. These appendages are essentially useless in their function as "silencing
devices".
Many categories of combustion engine powered model aircraft are no longer allowed in several densely
populated countries because they are too noisy. Imposing a blanket noise reduction will significantly
contribute to the regaining of the popularity of aeromodelling.
c) 1.3.1. Category F1 - Free Flight.
i) United Kingdom
a) Proposal to ban use of R/C in free flight competition models: Amend to read:
This is a flight during in which there exists no physical connection whatsoever between the
aeromodel and the competitor or his helper. Radio control functions are allowed only when
specifically stated in the rules for the relevant class. any person. Transmissions to the model
for the purpose of controlling the flight are not allowed at any time from the moment when an
attempt starts until the model returns to the ground. Exceptions to this rule are the use of a
launching cable to control a cable-launched glider during the launch and the steering of
indoor models as permitted by rule 3.4.7 in Section 4c.
b) Proposal to limit use of R/C in free flight competition models. Amend to read:
This is a flight during in which there exists no physical connection whatsoever between the
aeromodel and the competitor or his helper. Radio control functions are allowed only when
specifically stated in the rules for the relevant class. any person. Transmissions to the model
for the purpose of controlling the flight are not allowed at any time from the moment when an
attempt starts until the model returns to the ground. Exceptions to this rule are the use of a
launching cable to control a cable-launched glider during the launch and the steering of
indoor models as permitted by rule 3.4.7 in Section 4c.
If transmissions are used to control the flight, the score for that attempt is zero and the attempt
may not be repeated.
Reason: None given
ii) Italy. Amend to read:
This is a flight during which there exists no physical connection whatsoever between the aeromodel
and the competitor or his helper. Radio control functions are allowed only when specifically stated
in the rules for the relevant class. Any control or sequence of controls operated by systems inboard
is not allowed after the beginning of the flight except when specifically stated in the rules for the
relevant class.
Class: F1A - GLIDERS (A-2 class)
F1B - MODELS WITH EXTENSIBLE MOTORS (WAKEFIELD)
F1C - POWER MODELS
FID - INDOOR MODELS
F1E - GLIDERS WITH AUTOMATIC STEERING
F1F - HELICOPTER MODELS
FIG - MODELS WITH EXTENSIBLE MOTORS (COUPE D'HIVER)
F1H - GLIDERS (A-1 class)
F1J - POWER MODELS (1/2 A class)
F1K - MODELS WITH CO2 ENGINES
F1L - INDOOR EZB MODELS
Reason: See Annex B.
C2. PART TWO- GENERAL RULES FOR INTERNATIONAL CONTESTS
a) 2.3.9 - Israel. Amend to read:
Except for Indoor and Scale, each model must bear the nationality abbreviation of the International
Olympic Committee and for Free Flight models the FAI licence number or the National Identification
Number of the competitor., all this on the upper surface of the wing. The letters or figures of the
national abbreviation must be at least 25 mm high and appear at least once on each model (preferably on
the upper surface of the left wing for Free Flight models). See Annex 2 in Section 4b and examples on
the following pages.
Reason: Until recently, the FAI licence of the competitor appeared only on the FAI sticker and since it
is just a code there is no necessity to show it using big letters or figures.
Competitors with long FAI numbers need to cover a certain part of the wing un-necessarily.(In Israel, we
use a seven-digit number ........).
D. PART THREE - TECHNICAL REGULATIONS FOR FREE FLIGHT MODELS
D1 CLASS F1A - GLIDERS
a) 3.1.2. Characteristics of Gliders
i) - Russia. Amend to read:
Surface area (St) ............. 32 - 34 dm2
Minimum weight ............ 410 grammes
Maximum length of launching cable loaded by 5 kg ............ [50 ] 45 m
Rule B.3.1. of Section 4b does not apply to class F1A.
Reason: To reduce the number of competitors in a flyoff. to improve the identification of models
(particularly in a flyoff), to make a contest more interesting in main rounds.
ii) - Germany. Add the following:
At junior contests, the models shall have no timed moving surfaces other than rudder and
dethermalisers.
Reason: During the 1998 Junior World Championships, most juniors used models far beyond their
technical comprehension. It is against the philosophy of Junior Championships to have rather a
competition of the adult experts than of the junior contestants.
b) 3.1.6. An attempt may be repeated. - Germany. Amend to read:
a) the model collides with a person (other than the person who launched it) when being launched.
b) during towing, the model collides with a model in free flight (but not with a model being towed or
with a towline) and towing cannot continue normally.
c) during the flight the model collides with another model or a towline other than its own towline.
Should the model continue its flight in a normal manner, the competitor may demand that the flight is
accepted as an official flight, even if the demand is made at the end of the flight.
The repetition of an attempt must take place within a ten minute period after the end of the round or fly
off.
Reason: Unsuccessful attempts according to 3.1.6. are not a competitor's fault and therefore may be
repeated. If that occurs at the end of a round or during the fly off, the competitor must have a defined
timeframe to repeat the attempt.
c) 3.1.7. Duration of Flights - Italy. Amend to read:
[The maximum duration to be taken for each official flight in world and continental championships is to
be three minutes and thirty seconds for the first round and three minutes for subsequent rounds. These
maximum durations are to be used for other international events unless different durations have been
announced in advance and approved by CIAM for specific rounds.]
The maximum duration for all official flights is to be three minutes.
In the event of exceptional meteorological conditions or model recovery problems the Jury may permit the
maximum for a round to be reduced. Such a modified maximum must be announced before the start of the
round.
The flight begins when the towline leaves the model and this must happen within 5 minutes from the
declaration of launch by the competitor to the timekeeper.
Only D.T. devices are allowed after the beginning of the flight.
Reason: See Annex B.
d) 3.1.10 Number of Helpers - Germany. Amend to read:
The competitor is entitled to have one helper. At junior contests, no adult except the registered team
manager must be closer than 20 meters from the starting pole position and from the junior contestant in
the upwind starting area.
Reason: Abuse of the current rules during the 1998 Junior World Championships in Sibiu.
e) 3.1.11 Launching Devices. - Russia. Amend 3.1.11.a) to read:
The glider must be launched by means of a single cable and its length, including release equipment and
the launching device shall not exceed [50] 45 metres when subjected to a tensile load of 5 kg. This tensile
load shall be applied by means of an appropriate apparatus available to the competitors before and during
the competition and also to officials during the competition when checking at least 20% of the models.
Reason: To reduce the number of competitors in a flyoff. to improve the identification of models
(particularly in a flyoff), to make a contest more interesting in main rounds.
D2 CLASS F1B - MODELS WITH EXTENSIBLE MOTORS
a) 3.2.2. Characteristics of Model with Extensible Motor
i) - Italy. Amend to read:
Surface Area (St) 17 - 19 dm2
Minimum weight of model less motor(s) [195] 205 g
Maximum weight of motor(s) lubricated [35] 25 g
Rule B.3.1. of Section 4b does not apply to class F1B.
Reason: See Annex B
ii) - Russia. Amend to read:
Surface Area (St) 17 - 19 dm2
Minimum weight of model less motor(s) [195] 200 g
Maximum weight of motor(s) lubricated [35] 30 g
Rule B.3.1. of Section 4b does not apply to class F1B.
Reason: To reduce the number of competitors in a flyoff. to improve the identification of models
(particularly in a flyoff), to make a contest more interesting in main rounds. Now F1B models score
more advantage over F1A and F1C models. Very often one must fly 7 minutes and more to be a
winner. At the last European Championships in Portugal, 16 competitors met in fly offs. Three of
them had to fly more than 7 minutes early in the morning. It was not easy to identify and track
models in fair weather conditions.
iii) - Germany. Add the following:
At junior contests, the models shall have no timed moving surfaces other than rudder and
dethermalisers.
Reason: During the 1998 Junior World Championships, most juniors used models far beyond their
technical comprehension. It is against the philosophy of Junior Championships to have rather a
competition of the adult experts than of the junior contestants.
b) 3.2.6 Repeat of an Attempt - Germany. Amend to read:
An attempt may be repeated when the model collides with another model in flight, or a person other than
the competitor himself while being launched. Should the model continue its flight in a normal manner,
the competitor may demand that the flight be accepted as an official flight, even if the demand is made at
the end of the attempt. The repetition of an attempt must take place within a ten minute period after the
end of the round or fly off.
Reason: Unsuccessful attempts according to 3.1.6. are not a competitor's fault and therefore may be
repeated. If that occurs at the end of a round or during the fly off, the competitor must have a defined
timeframe to repeat the attempt.
c) 3.2.7. Duration of Flights - Italy. Amend to read:
[The maximum duration to be taken for each flight in World and Continental Championships is to be
three minutes and 30 seconds for the first round and three minutes for subsequent rounds. These
maximum durations are to be used for other international events unless different durations have been
announced in advance and approved by CIAM for specific rounds.]
The maximum duration for all official flights is to be three minutes.
In the event of exceptional meteorological conditions or model recovery problems the Jury may permit the
maximum for a round to be reduced. Such a modified maximum must be announced before the start of the
round.
The flight begins when the competitor releases the model and this must happen within 5 minutes from the
declaration of launch by the competitor to the timekeeper.
Only the folding of the propeller and D.T. devices are allowed after the beginning of the flight.
Reason: See Annex B.
d) 3.2.10. Number of Helpers. - Germany. Amend to read:
The competitor is entitled to have one helper at the starting pole position. At junior contests, no adult
except the registered team manager must be closer than 20 meters from the starting pole position and
from the junior contestant in the upwind starting area.
Reason: Abuse of the current rules during the 1998 Junior World Championships in Sibiu.
D3. CLASS F1C - MODELS WITH PISTON MOTORS
a) 3.3.2. Characteristics of Models with Piston Type Motors - Italy. Amend to read:
Maximum swept volume of motor(s) 2,5 cm3
No exhaust extensions whatsoever are allowed to the exhaust opening(s) of the motor
Minimum total weight 300 g/cm3 swept volume of motors
Minimum loading ......................................................... 20 g/dm2
[Maximum duration of motor run: 5 seconds from release of model.]
Rule B.3.1. of Section 4b does not apply to class F1C.
Fuel of motor run is determined by 25 cm length tube (standard commercial 2 mm inside ? silicon-
rubber tube) supplied by the organisers before the contest. The tube is to be entirely external and visible
from the carburettor to a reserve tank from which it is to be detached when the model is released.
Fuel to a standard formula for glow plug and spark ignition motors will be supplied by the organisers, and
must be used for every official flight. The composition shall be as follows: 80% methanol, 20% castor oil.
Note: Fuel for compression ignition motors is not restricted.
Before each attempt for an official flight the fuel tank must be rinsed (washed out) with standard formula
fuel.
F1C models may use radio control only for irreversible actions to restrict the flight, that is motor stop or
dethermalisation. Any malfunction or unintended operation of these functions is entirely at the risk of the
competitor.
Reason: See Annex B
b) 3.3.5. Definition of an Unsuccessful Attempt - Italy. Delete 3.3.5.a)
An attempt is classed as unsuccessful if the model is launched and at least one of the following events
occur. If this happens on the first attempt then the competitor is entitled to a second attempt.
a) the time of the motor run from the release of the model exceeds the time specified in 3.3.2. or 3.3.8
as appropriate for the flight.
b) when a part of the model becomes detached during the launch or during the flight.
c) the duration of the flight is less than 20 seconds.
Reason: The time of the motor run is longer specified in 3.3.2.
c) 3.3.6. Repeat of an Attempt - Germany. Amend to read:
An attempt may be repeated when the model collides with another model in flight, or a person other than
the competitor himself while being launched. Should the model continue its flight in a normal manner,
the competitor may demand that the flight be accepted as an official flight, even if the demand is made at
the end of the attempt. The repetition of an attempt must take place within a ten minute period after the
end of the round or fly off.
Reason: Unsuccessful attempts according to 3.1.6. are not a competitor's fault and therefore may be
repeated. If that occurs at the end of a round or during the fly off, the competitor must have a defined
timeframe to repeat the attempt.
d) 3.3.7. Duration of Flights. - Italy. Amend to read:
[The maximum duration to be taken for each flight in World and Continental Championships is to be four
minutes for the first round and three minutes for subsequent rounds. These maximum durations are to be
used for other international events unless different durations have been announced in advance and
approved by CIAM for specific rounds.]
The maximum duration for all official flights is to be three minutes.
In the event of exceptional meteorological conditions or model recovery problems the Jury may permit the
maximum for a round to be reduced. Such a modified maximum must be announced before the start of the
round.
The flight begins when the competitor releases the model and this must happen within 5 minutes from the
declaration of launch by the competitor to the timekeeper.
Only the folding of the propeller and D.T. devices are allowed after the beginning of the flight.
Reason: See Annex B.
e) 3.3.8. Classification - Italy. Delete 3.3.8.e)
a) See 3.1.8.a.
b) See 3.1.8.b.
c) Starting positions will be decided by a draw for each flyoff. The organiser will establish a 10 minute
period during which all flyoff competitors must start their engines and launch their model. Within
these 10 minutes the competitor will have the right to a second attempt in the case of an
unsuccessful attempt for an additional flight according to para 3.3.5.
d) See 3.1.8.d.
[e) See 3.1.8.e. The motor run is 5 seconds.]
Reason: The time of motor run is no longer specified.
f) 3.3.9. Timing - Italy. Delete 3.3.9.c)
a) See Section 4b, para. B.9.
b) The timing of flights is limited to the durations specified in 3.3.7. and 3.3.8. The total flight time is
taken from the launch of the model to the end of the flight.
c) The motor run must be timed by two timekeepers with quartz controlled electronic with digital
readout The motor run is determined as the average of the two registered times, and this average is
reduced to the nearest 1/10th of a second below.
Reason: The time of motor run is no longer specified in 3.3.2.
D4. CLASS F1D - INDOOR MODELS
a) 3.4.2. Characteristics of Indoor Models.
i) France. Amend to read:
The span of the model shall not exceed [650 ] 550 mm. The weight of the model without rubber motor
shall not be less than [1 ] 1,2 gram. This restriction does not apply to record attempts.
Reasons: 1. The modification of the wing span makes possible carrying the models as cabin
baggage during air trips avoiding damage to the models.
2. At the minimum weight of 1 gram , the models are extremely fragile and difficult to
build. The difficulty to get good materials (Balsa and microfilm) to build a model at the
minimum weight is a serious argument against the development of the F1D class. The
increase of the weight will probably bring new comers to F1D class, particularly
youngsters.
ii) Hungary. Amend to read:
The span of the model shall not exceed [650] 550 mm. The weight of the model without rubber motor
shall not be less than [1] 1,2 gram. The weight of the lubricated motor shall not be more than 0,5
gram. This restriction does not apply to record attempts. These restrictions do not apply to open
record attempts.
Reason: As agreed by the majority of competitors, the need has arisen to change F1D model
specifications because of problems with:
? access to good quality balsa wood (to be able to build close to 1 gram);
? access to good quality microfilm, also some wish to use plastic film;
? transportation of models (the models are too fragile; safe transport of big boxes on airliners is
nearly impossible);
? access to suitable big halls for training and for contests;
? finding organisers for championships (recently there have been only two counties active,
Romania and perhaps the USA because of the financial risk caused by the too high rental costs
of suitable big halls, too long a duration of the championships because of the extremely high
performance of F1D models and the decreasing participation).
? participation in general (because of the problems above); and
? involving new competitors (because of the extremities of the class).
The proposal is based on experience, discussions, questioners and special experiments and is a
summary of different suggestions made by different persons. The proposals also reflects the changes
in the record section.
See also Annex C.
b) 3.4.9. Timing of Flights. - Hungary. Amend sub paragraph 3.4.9.a) to read:
a) the model comes to rest touches on the floor of the building.
Reason: The proposal will solve the present uncertainty in terminating flights that may cause up to about
5 seconds difference in recorded time.
D5. CLASS F1E - SLOPE SOARING GLIDERS
a) 3.5.6. Repeat of an Attempt. - Germany. Amend to read:
An attempt may be repeated when the model collides with another model in flight, or a person other than
the competitor himself while being launched. Should the model continue its flight in a normal manner,
the competitor may demand that the flight be accepted as an official flight, even if the demand is made at
the end of the attempt. The repetition of an attempt must take place within a ten minute period after the
end of the round or fly off.
Reason: Unsuccessful attempts according to 3.1.6. are not a competitor's fault and therefore may be
repeated. If that occurs at the end of a round or during the fly off, the competitor must have a defined
timeframe to repeat the attempt.
E. SECTION 4e - PROVISIONAL RULES
E1 CLASS F1G - MODELS WITH EXTENSIBLE MOTORS, COUPE D'HIVER
a) 3.G.2. Characteristics of Model with Extensible Motor, Coupe D'Hiver. - Italy. Amend to read:
Minimum weight of model less motor(s) ...........70 g
Maximum weight of motor (s) lubricated ..........10 g
The number of models eligible for entry by each competitor is three.
Rule B.3.1. of Section 4b does not apply must be applied to class F1G.
Reason: Rule B.3.1. of Section 4b must be applied to class F1G.
b) 3.G.7. Duration of Flights - Italy. Amend to read:
The maximum duration to be taken for each official flight is to be two minutes. In the event of
exceptional meteorological conditions or model recovery problems, the Jury may permit the maximum for
a round to be changed. Such a modified maximum must be announced before the start of the round.
The flight begins when the competitor releases the model and this must happen within five minutes from
the declaration of launch to the timekeeper.
Only the folding of the propeller and D.T. devices are allowed after the beginning of flight.
Reason: See Annex B.
E2 CLASS F1H - GLIDERS. A-1 FORMULA
a) 3.H.2. Characteristics of Models, A-1 Formula
i) Germany. Amend to read:
Maximum Surface area (St) ...........................................18 dm2
[ Minimum weight ..................................................220 g]
Maximum length of launch cable loaded by 2 kg............50 m
The number of models eligible for entry by each competitor is three.
Rule B.3.1. of Section 4b does not apply to class F1H
Reason: In most countries pupils and juniors construct gliders with less than 18 dm2 surface (e.g.
Kleiner Uhu, Windrush). They should be allowed to compete with these models in F1H without a
minimum weight of 220 g. Gliders smaller than 18 dm2 but weighing 220 g are very difficult to
handle.
ii) Italy. Amend to read:
Maximum Surface area (St) ...........................................18 dm2
Minimum weight ........................................................220 g
Maximum length of launch cable loaded by 2 kg............50 m
The number of models eligible for entry by each competitor is three.
Rule B.3.1. of Section 4b does not apply to class F1H
Reason: Rule B.3.1. of section 4b must be applied to class F1H.
b) 3.H.7. Duration of Flights - Italy. Amend to read:
The maximum duration to be taken for each all official flight is to be two minutes. In the event of
exceptional meteorological conditions or model recovery problems, the Jury may permit the maximum for
a round to be changed. Such a modified maximum must be announced before the start of the round.
The flight begins when the towline leaves the model and this must happen within 5 minutes from the
declaration of launch by the competitor to the timekeeper.
Only D.T. devices are allowed after the beginning of the flight.
Reason: See Annex B.
E3 CLASS F1J - MODELS WITH PISTON MOTORS, 1/2 A FORMULA
a) 3.J.2 Characteristics of Model with Piston Type Motors - 1/2A.
i) Italy. Amend to read:
Maximum swept volume of motor(s) .............1,00 cm3
No extensions whatsoever are allowed to the exhaust opening(s) of the motor(s).
Minimum total weight ..........................160 g
Minimum loading ........................................ 20g/dm2
[Maximum duration of motor run ..................... 7 seconds from release of model.]
Fuel of motor run is determined by 20 cm length tube (standard commercial 2 mm inside ? silicon-
rubber tube) supplied by the organisers before the contest. The tube is to be entirely external and
visible from the carburettor to a reserve tank from which it is to be detached when the model is
released.
Fuel constituents are not restricted.
The number of models eligible for entry by each competitor is three.
Rule B.3.1. of Section 4b does not apply to class F1J.
Reason: 1. See Annex B.
2. Rule B.3.1 must be applied to class F1J.
ii) Russia. Amend to read:
Maximum swept volume of motor(s) .............1,00 cm3
No extensions whatsoever are allowed to the exhaust opening(s) of the motor(s).
Minimum total weight ..........................160 g
Minimum loading .......................................... 15 g/dm2
Maximum duration of motor run ..................... [7 ] 5 seconds from release of model.
Fuel constituents are not restricted.
The number of models eligible for entry by each competitor is three.
Rule B.3.1. of Section 4b does not apply to class F1J.
Reason: The need to introduce the above changes was already evident at the first World
Championships in this class where 50% of the competitors achieved maximum results in qualifying
rounds. The proposed requirements will make a sporting flight harder and reduce the time needed to
run competitions in this class.
iii) Germany. Add the following:
At junior contests, the models shall have no timed moving surfaces other than rudder and
dethermalisers.
Reason: During the 1998 Junior World Championships, most juniors used models far beyond their
technical comprehension. It is against the philosophy of Junior Championships to have rather a
competition of the adult experts than of the junior contestants.
b) 3.J.5. Definitions of an Unsuccessful Attempt. - Italy. Delete 3.J.5.b)
An attempt is classed as unsuccessful if the model is launched and at least one of the following events
occur. If this happens on the first attempt, then the competitor is entitled to a second attempt.
a) The flight duration is less than 20 seconds.
b) The motor run exceeds 7 seconds from the release of the model.
c) A part of the model becomes detached during the launch or during the flight time.
Reason: The time of motor run is no longer specified in 3.J.2.
c) 3.J.7. Duration of Flights - Italy. Amend to read:
The maximum duration to be taken for each all official flight is to be two minutes. In the event of
exceptional meteorological conditions or model recovery problems, the Jury may permit the maximum for
a round to be changed. Such a modified maximum must be announced before the start of the round
The flight begins when the competitor releases the model and this must happen within five minutes from
the declaration of launch to the timekeeper.
Only the folding of the propeller and D.T. devices are allowed after the beginning of flight.
Reason: See Annex B.
d) 3.J.9. Timing. - Italy. Delete 3.J.9.c).
a) See Section 4b, para. B.9.
b) The total time of flight is taken from the launch of the model to the end of the flight.
c) The motor run must be timed by two timekeepers with stopwatches or timing devices registering to
at least 1/10th of a second. The motor run is determined as the average of the two registered times
and the average is reduced to the nearest 1/10th of a second below.
Reason: The time of motor run is no longer specified.
e) 3.J.10 Number of Helpers. - Germany. Amend to read:
The competitor is entitled to have one helper at the starting position. At junior contests, no adult except
the registered team manager must be closer than 20 meters from the starting pole position and from the
junior contestant in the upwind starting area.
Reason: Abuse of the current rules during the 1998 Junior World Championships in Sibiu.
E4 CLASS F1K - MODELS WITH CO2 ENGINES
a) 3.K.11. Launching - Germany Delete the second sentence of 3.K.11.b):
a) Launching is by hand, the competitor being on the ground (jumping allowed).
b) Each competitor must start his motor and launch the model himself. The filling procedure must be
made under control of the timekeepers and no artificial cooling is allowed other than to release CO2
from the tank ("pin out")
c) The model must be launched within approximately 5 m from the starting pole position.
Reason: The rule is too difficult to follow by beginners, particularly because filler nozzles of a few
engine types only makes it possible to pin out the carbonic acid. The contestant should be free to use the
filling system he prefers. With models of 75 g there is no advantage using one method or the other.
F. SUPPLEMENTAL TO THE SPORTING CODE (FREE FLIGHT)
F1. A GUIDE FOR THE ORGANISERS OF CONTESTS IN OUTDOOR FAI FREE FLIGHT CLASSES.
a) Free Flight Subcommittee. Replace the Organisers Guide, Appendix A and Appendix B.
See Annex D.
Reason: The Guide has been revised to come into line with the changes to the Sporting Code and to take
into account latest practices in competitions and clarifications required.
Revision markings in the guide show proposed changes compared to 1993 issue in order to aid CIAM
consideration of changes.

Roger and Ian
I have just read the crazy set of proposals for F1B (F1A & F1C ain't much
better).
25 grams of rubber 205 grams of model and only a d/t allowed. No VIT no VIW
no DPR or IPR. If this happens there will be one who won't be in the fly off
as I'll not be there. Words fail me but this is going backwards, net step
free wheelers only?
