SAFETY
& GENERAL PYLON RULES:
5.1.1.1.
Safety Headgear:
All
officials on the racecourse and all competitors must wear a
crash helmet with a chinstrap.
5.1.1.2.
Model Aircraft Airworthiness:
The
Contest Director has the right to request any competitor to
make a flight to demonstrate the airworthiness of his model
aircraft and/or ability to fly the airplane around the
course. If during the race, the Contest Director considers
any model aircraft to be flying erratically, dangerously, or
so low as to endanger Course Officials, he may disqualify
the competitor from that heat or from all heats and requires
the model aircraft to be landed as soon as practicable.
Persistent flying below the top of the pylons may be
considered dangerous.
5.1.1.3
Racecourse Safety:
The
racecourse specification may be modified in the interest of
safety or to suit field conditions if safety is not
compromised.
5.1.1.4
Builder Of The Model Aircraft
This
is not applicable to Australian Pylon Classes.
5.1.1.5
Ballast
If used to
balance the Model Aircraft - it must be permanently and
safely affixed.
5.1.1.6
Fuel
The
organisers will supply fuel to a standard formula for glow
plug and spark ignition motors. Its composition shall be 80%
methanol, 20% castor oil – unless it is specified otherwise,
in the Pylon Class Rules.
5.1.1.7
Jettisoning
The loss
of any part of the model aircraft after the starting signal
(flag drop or light signal) and before the engine stops
disqualifies the model aircraft for that flight, except as a
result of a collision - if a rerun condition applies.
5.1.1.8.
Engine Shutdown:
The engine
must be able to be stopped within 5 seconds of a starter’s
instruction to do so. (In Half A the requirement is within
20 seconds). If this is not done that heat score of the
competitor is recorded as 200 points.
5.1.1.9.
Aircraft Collisions:
After the
starting signal (flag drop or light signal) is given, any
contact between model aircraft shall be considered a
collision and the model aircraft involved must land as soon
as it is safe to do so. The Contest Director is required to
give such competitors a second opportunity to record a score
in that round. Provided that in his opinion the aircraft is
still airworthy or the competitor has an airworthy reserve
model aircraft. The Competitor will not be awarded a rerun
if the collision occurred after the 10 laps have been
completed and the competitor has received an official score.
5.1.1.10.
Timing Malfunction
In the
event of an official’s error, or a malfunction of the
timing, lap counting, signalling or other such equipment
which is the responsibility of the organizers, the
competitor's affected by such malfunction shall be granted a
re-run of that round.
5.1.1.11.

5.1.1.13
Pylon Construction
Pylons
must be brightly coloured and should have a Minimum Height
of 4m and not exceed 5m in Height.
5.1.1.14
Method of Team Selection for Pylon Classes at International
Competitions.
5.1.1.14.1 Purpose
The MAAA
team selection trials procedure recommends that only one
Australian team selection trial be conducted to select the
Australian team. However they are allowing that individual
recognised National Special Interest Groups (NSIG),
or MAAA Technical Sub-committee if there is no NSIG, may
decide on any selection process method that they prefer
provided they obtain permission from the MAAA.
For
approval to run multiple trials for a specific World
Championships, AMPRA shall apply in writing to the MAAA
Executive. The application shall indicate the reason(s) for
seeking the change, the selection process to be used, and
the approximate dates and in which States the multiple
trials are to be run.
An
exemption to run multiple team trials is only applicable to
the conduct of the team trial process for one championship.
A new application for multiple team trials is required for
each World Championship.
5.1.1.14.2 Number of Trials
Each
competitor shall have the option of qualifying in up to 3
selection events, (with a) minimum of 2 events required.
The 3
selection events should normally be;
The AMPRA
championships
The
Nationals
The State
championships in the competitors home state.
If required, alternate event(s) may be nominated by the
AMPRA committee.
If a
competitor does not attend the state championships in their
resident state or such event is not run, they may nominate
an alternate state championship event. If doing so, they
must notify the AMPRA committee in writing at least 1 week
prior to the running of their home state champs if these
State Champs are to be conducted and at least one week prior
to an alternative State Champs.
5.1.1.14.3 Date of Team Selection Trial
The MAAA
Secretary will advise all disciplines of the expected dates
for all World Championship events.
The trials
should be conducted no earlier than 18 months or later than
6 months before the international competition.
The final
decision on the actual location and dates of the team trials
will be decided by the AMPRA committee.
5.1.1.14.4 Venue of Team Trial and organiser of the trial
The AMPRA
committee shall have the overall responsibility for the
selection of the team. The venue of the team trials
and actual organisers for the trials are to be approved by
the AMPRA committee.
5.1.1.14.5 Notification of Team Trials.
All known
trial dates are to be officially given to the executive of
the MAAA no later than 6 months before the trial is held.
Details of date, venue, accommodation and a plan of location
should be circulated at least three months prior to the
trial. The MAAA executive will assist in this matter.
5.1.1.14.6 Eligibility to participate in a trial.
All MAAA
Financial Affiliate members are entitled to enter W/C Team
Selection Trials, even if they are not a member of AMPRA. If
successful, such team members will also be entitled to
nominal support from the MAAA for uniforms and entry fee
only
5.1.1.14.7 Conduct of team trial
A minimum
of 5 rounds of racing shall be conducted at selection events
or the event will not be deemed to have been a team trial.
The first
5 placing competitors for all team selection events must
have their model(s) processed. Documented proof of this
processing shall be returned to the AMPRA committee by the
CD of the event. Failure to provide this documented proof
may result in the scores for this event not being counted.
The recommended format for this document will be available
from the AMPRA committee.
5.1.1.14.8 Team Selection
At each of
the team selection events attended by a competitor, each
competitor’s official scores are added together then
averaged to give the average score for the event. [The
average is the sum of each competitor's official score
divided by the number of rounds which count in the final
score and not by the number of rounds flown] The team
selection ranking for each competitor will be based on the 2
lowest scores of the selection events attended. The average
of these 2 scores will be used to select the team with the
lowest average scores of the top three competitors to be
offered a place on the team. If a competitor does not wish
to be on the team the next available competitor with the
lowest score will be offered a place.
5.1.1.14.9 Cancellation of a Team Trial
When
weather conditions are such that the team trial is abandoned
then another team trial can be organised. If it is likely
that time may become a factor then the requirement that a
trial must be held no later than 6 months before a W/C can
be waived. The MAAA will be duly notified of this and the
proposed team trial details.
5.1.1.14.10 Acceptance of a Place on an International Team.
A person
offered a position in the team shall advise AMPRA, in
writing, no later than the date specified by AMPRA if they
wish to accept the offer. Failure to notify AMPRA in
writing of their intention by the date specified shall be
considered a rejection of the offer. The team place shall
then be offered to the next eligible person who shall be
advised a date to notify AMPRA of their acceptance or
rejection of the offer.
AMPRA
shall advise the MAAA secretary of the Team Members as soon
as the final team is selected.
The MAAA
Secretary shall arrange payment of the MAAA support, to the
extent approved by the Council, to the Team Members. The
payment of the MAAA support shall be made after documented
proof of the payment of the entry fees has been received by
the MAAA Secretary. It is the responsibility of the Team
Manager, or if is none has been appointed, AMPRA, to arrange
the payment of the entry fees.
5.1.1.14.11 Rules
AMPRA will
decide in conjunction with the F3D Technical Sub Committee
the rules that will apply at all trials. Normally the rules
used at any Australian team trial will be the pylon rules
that are written in the Australian rules book.
If AMPRA
is aware of any rules changes that could affect the
Australian team they have the right to include or exclude
them in the team trials.
5.2.
RACE
ORGANIZATION:
5.2.1.
OPERATION OF THE RACE
5.2.1.1.
Flight timers and lap counters:
Each
competitor shall be assigned a timer for each heat. This
official will time the competitor’s aircraft for the
required ten laps. In doing so he will count the laps flown,
and signal the completion of the race. He will keep the
recorded time on his electronic stopwatch until the time has
been entered on the score sheet.
5.2.1.2
Caller’s Responsibilities:
The caller
is required to launch the Pilot’s model aircraft – then
direct the Pilot throughout the race – and advise the Pilot
when his race is finished
5.2.1.3.
No1 Signalers:
The number
1 pylon shall have one pylon judge and an official signaller
for each competitor in the heat. Each signaller will operate
a light of a distinctive color that is located at #1 pylon.
The
signallers' will have their lights off as the aircraft reach
midcourse between #3 and #1 pylons, or earlier. At the
instant the model aircraft draws level with the #1 pylon the
signaller will switch his light on.
If a Model
Aircraft turns short before reaching the pylon – the No1
signaller will not switch on his light.
The No1
Signallers will award a side line cut to any person who
fly's behind the No1 Signalling cage. However they will
switch on the light only when they are sure that the
contestant has completed the full distance to the No1 Pylon.
5.2.1.4
Side Line Judge:
The Side
Line Judge will record as an infringement, any over flight
of the sideline during or after the race.
The judges
for #2 and #3 pylons will record any cut pylon infringements
during the race. At the end of each race the Sideline and
Pylon Judges will inform the timing official of any
infringement by any competitor.
5.2.1.5.
Race Starter Responsibilities:
The Race
Starter is in charge of each heat; the starter will ensure
that all competitors and Race Officials are ready to
commence. The starter will arrange for each model aircraft
to be identified by one signaller before the start of any
heat. A radio operation check from each competitor will be
made prior to starting engines.
The race
starter will notify all competitors when the one minute
countdown has commenced, and ensure that no engines are
started prior to this advice.
5.2.2
CONDUCT OF THE RACE:
5.2.2.1.
Model Aircraft per Heat:
A maximum
of 4 model aircraft per heat will be allowed.
5.2.2.2.
Starting Positions:
Starting
positions in all races will be allocated by the starter -
with the #1 position being closest to #2 pylon. Model
aircraft will be released from the starting line on the
starting signal (flag drop or light signal) at a minimum of
one-second intervals with timing commencing at the starting
signal for that particular model aircraft.
Starting
positions will change after each round –with the pilot
moving to the next position on the start line.
5.2.2.3.
Heat Format:
Heats
shall be arranged in accordance with the radio frequencies
in use to permit simultaneous flights.
5.2.2.4.

but hand pushing is permitted. (Hand Launch is allowed in
Half A).
5.2.2.5.
Race Direction:
All laps
are to be flown counter-clockwise with turns to the left.
5.2.2.6
Starting Time Duration:
After the
starter has announced that the one minute count down has
commenced, the competitors may start and tune their engines.
After that
minute the racing will commence – at flag fall or light
signal.
A
competitor whose engine is not running at the end of the
1-minute period will be disqualified from the heat. No
competitor shall be permitted to take off once the first
model aircraft has passed the start/finish line heading from
#1 to #2 pylon on the first lap, and no time shall be given
him for that heat.
5.2.2.7.
Duration of Race:
The race
is terminated at the start-finish line after ten 10 laps
have been completed. Those who have not completed the ten
laps will get a 200 points score – except if they have been
granted a rerun.
At the
completion of the 10 laps the pilot must immediately remove
his aircraft from the course. The pilot shall land his
aircraft promptly if instructed by the Starter.
5.2.2.8.
Early Release of Model Aircraft:
A penalty
will be incurred if the competitor releases the model
aircraft before the drop of the starter's flag or starting
signal.
5.2.2.9.
Model Aircraft Obstructing Normal Take Off:
If another
competitor impedes the normal take off of a Model Aircraft.
The caller who is about to launch a Model Aircraft can abort
his take off if he considers that there is a danger of
hitting the Model Aircraft that caused the obstruction. He
then must inform the Starter what happened. If the starter
agrees that the aborted take off was valid, he will grant
that competitor a re-run of that round.
5.2.2.10.
Pilots Helpers (Callers):
Each
competitor must have one helper (For Safety Reasons) in each
race and the helper may release the model aircraft at the
start and give the pilot verbal information regarding the
flying course of his model aircraft and official signals.
No more
than one helper (Caller) is allowed per pilot – with the
exception of physically disabled Pilots as Detailed in these
rules.
The pilot
or caller of one team may act as the caller in other teams.
However, more than one team may not use the same aircraft,
nor roles be interchanged in a team using the same aircraft.
Any award
will be made jointly to team members. (A team entry is only
applicable to the “AI” class).
5.2.2.11.
Physically Disabled Pilots:
An extra
helper is permitted to assist where the competitor is
physically disabled, for example, paraplegic. This helper is
not eligible for a team award nor is he required to pay an
entry fee (If Applicable) but is required to be a member of
a MAAA affiliated club.
5.2.2.12.
Electronic Pilot Assistance:
Electronic
communication with the pilot is prohibited.
5.2.3.
SCORING
5.2.3.1.
Timing of Model Aircraft:
The flight
of each model aircraft shall be timed by a lap
counter/timekeeper with a timing device measuring to at
least 1/100th of a second. Timing shall start when the
starting signal is given to the individual competitor. The
lap counter/timekeeper stops his timing device after the
competitor has completed ten laps.
At the
completion of each heat, the elapsed time from the timing
devices is recorded on the Competitors Score Sheet.
The pylon
and sideline judges will notify the Scorer the aircraft that
have infringed. The Scorer will then record the total number
of infringements for each competitor on his score sheet.
The score
sheets are then processed by a Scorer who will:
a) If
one infringement was incurred, add 1/10th of the flyer's
time for ten laps to give the corrected time;
b) If
two or more infringements were incurred, cancel the flight
thereby resulting in a 200 point score;
c)
Round the competitor's corrected time to the nearest 1/10th
of a second.
5.2.3.2.
Allocation of Points Score:
Points
shall be awarded after each race as follows: The
competitor's score is his corrected time in seconds to the
first decimal place. If the competitor fails to complete his
flight or is disqualified the score shall be 200.
5.2.3.3.
Determination of Event Winner:
The winner
of the event is the competitor who has accumulated the
lowest score after the conclusion of all heats. If four or
more rounds are flown, each competitor's worst score shall
be discarded. If nine or more rounds are flown, each
competitor's worst (highest) two scores shall be discarded.
5.2.3.4.
Procedure relating to Event Ties:
If the
time permits and there is no frequency conflict, ties shall
be broken by a fly off race. Otherwise, the best single race
score shall be considered in resolving a tie.

width of 75mm.
As passed
at the 2009 MAAA rules conference, the new wording is;
Cross
Section -
The fuselage shall have a minimum height of 127 mm and a
minimum width of 75 mm, the measurements to be of the
fuselage body and are to exclude any fins, attachments or
spacers. Both minimum dimensions must occur at the same
cross-section location. The fuselage will have a minimum
cross- sectional area of 80.6 cm2, excluding fillets.
Competitors will be required to provide templates to prove
this. Fillets are not considered part of the fuselage or

Wing Thickness:
The depth
of the wing must be a minimum of 22mm at the root of the
root cord of a monoplane, and 17 mm if a biplane. On a
biplane with wings of a different size, the smaller wing
must be at least 15mm thick at the root.
If the
wing is not uniform in thickness, then the thickness must
decrease in a straight line from root to tip as viewed from
the leading or trailing edge.
Note:
“Root” is defined as the innermost wing
section, excluding fillets that may be measured without
removing the wing from the fuselage. On a completely exposed
wing, much as that of a parasol monoplane or the top wing of
most biplanes, the root is that section of the wing that is
intersected by a projection of the outline of the fuselage
as seen in the top view, i.e. The root section would be 50mm
