1. Technical Specifications
Motor
All types of 380/400 (speed 400 or similar) electric
powered motors are allowed. The motor(s) should be commanded by radio control and the
pilot must provide a means to cut the electrical leads towards the motor(s).
Battery
The electric power shall be provided by a maximum of
7 NiCd cells with a maximum weight of 225g.
Model
Weight, including all equipment necessary for flight
shall not be more than 700g. There is no additional restriction.
2. Racing Course Specification
The triangular course will be laid out as follows:
the distance between pylon No. 1 and No. 2 is 80m. The distance between pylon No.1 and No.
3 is also 80m. The distance between pylon No. 2 and pylon No. 3 is 30m. The start/finish
line is in line with the plane through turns 2 and 3, and in the direction of No. 1. The
course is twelve (12) laps with individual length of 190m. Total distance travelled is
2.28km. The race starts at the start/finish line. All take-offs will be hand launched, no
mechanical device will be used. The race is terminated at the start/ finish line 12 full
laps later. The race course specification may be modified in the interest of safety. The
pylons should have a minimum height of 2m and should not exceed 4m height.
3. Operation of the Race
3.1 Flight Timers and Lap Counters: Each competitor
shall be assigned one official during each heat. The official will time the competitor's
aircraft for the required twelve laps. In so doing, he will count the laps flown and
advise the pilot when he has completed the necessary twelve laps. He will keep the
recorded time on his timing device until he has entered the time on the score sheet under
the supervision of the starter. Furthermore the official will also be responsible for
judging turn 3. At the No.1 pylon there will be one Pylon Judge and an Official Signaller
for each competitor in the heat. The Pylon Judge will stand in close proximity to the
pylon. The signaller will stand perpendicular to the direction of the course on the right
hand side of the pylon, as seen by the competitors, no more than 5 metres away from the
pylon. Each signaller will have a distinctive colour allocated, and the Contest Director
will arrange for each model to be identified by one signaller before the start of every
heat. Note: Signals may be coloured flags, lights or shutters.
3.2 The signallers will have their flags in a ready
position, or their lights off as the aircraft reach midcourse between No. 3 and No. 1
pylons, or earlier. At the instant the model draws level with the No.1 pylon on the
correct side the signaller will briskly lower his flag or switch his light on. There will
be no pilot's helpers at any of the pylons.
3.3 At the No. 2 and No. 3 pylons, the Official
Judge will stand in close proximity to the pylon they are judging.
3.4 A Sideline Judge will be posted in the front on
the pit area on the spectator side of the racing course. The Sideline Judge will record as
an infringement, any overflight of the pit or spectator areas. The judges at the No. 2 and
No. 3 pylons will record a cut pylon (infringement). At the end of each race the Sideline
and Pylon Judges will inform the Race Starter of any infringements by any competitor.
3.4 A maximum of 5 models per heat will be allowed.
3.5 The Race Starter is in charge of each heat. The
Starter will first ensure that all competitors and Race Officials are ready to commence.
Each signaller will have a flag or light of a distinctive colour. The starter will arrange
for each model to be identified by one signaller before the start of any heat. A radio
operation check from each competitor will be made prior to identification. A maximum of
one minute will be allowed after identification of all models of the heat at which point
the race will commence. A competitor whose model is not ready to fly at the end of the one
minute period will be disqualified from the heat. No competitor shall be permitted to
launch once the first model has passed the start/finish line heading from No. 1 to No. 2
pylon on the first lap and no time shall be given him for that heat.
3.6 All laps are to be flown counter-clockwise with
turns to the left. No minimum altitude is required for racing.
3.7 At the completion of the ten laps, the Lap
Counter/Timekeeper must immediately instruct the competitor to remove his aircraft from
the course.
3.8 A penalty will be incurred if the competitor
releases the model before the drop of the starter's flag, cuts a pylon or flies outside
the Sideline Judge. Two infringements constitute disqualification for that flight.
3.9 Starting positions in all races will be
determined by draw with No.1 position being closest to the No. 2 pylon. Models will be
flagged off the starting line simultaneously with timing commencing at the drop of the
flag.
3.10 The Contest Director has the right to request
any competitor to make a flight to demonstrate the airworthiness of his model and/or his
ability to fly the aeroplane around the course. If during the race, the Contest Director
considers any model 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 require
the model to be landed immediately. Persistent flying below the top of the pylons may be
considered dangerous to Course Officials.
3.11 Each competitor may have only one helper in
each race and the helper may release the model at the start and give the pilot verbal
information regarding the flying course of his model and official signals. The designation
"competitor" may refer to an individual or team entry of no more than two
persons. Any award will be made jointly to team members. The pilot or mechanic of one team
may act as the mechanic/helper in one or more other teams. However, any one model may not
be used by more than one team, nor may roles be interchanged in a team.
3.12 After the starting flag has dropped, any
contact between two models shall be considered a collision and the models involved must
land immediately. 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. In the event of a
malfunction of the timing, lap counting, signalling or such equipment which is the
responsibility of the organisers, the competitor(s) affected by such malfunction shall be
given the opportunity to record a score for that round.
3.13 The loss of any part of the model after the
drop of the flag and before the motor stops disqualifies the model for that flight except
as a result of a collision when Paragraph 3.12 applies.
4. Scoring
4.1 As many heats as possible will be flown but at
least three.
4.2 The flight of each model shall be timed with a
timing device (measuring to at least 1/10 second) by a lap counter/timekeeper. Timing
shall start when the starting signal is given to the individual competitor. The lap
counter/timekeeper stops his timing device after twelve laps have been completed by the
competitor. The elapsed time of each competitor will be transmitted, supervised by the
starter, from the timing device onto the competitor's score sheet. At the completion of
each heat, the pylon and side-line judges notify the starter as to which models have
infringed. The starter then advises the person who is responsible for the score sheet of
those who will record the total number of infringements for each competitor on the
individual score sheet. The score sheets are then processed by a scorer who will:
a) if one infringement has incurred, add 1/12 of the
flyer's time for twelve laps to give the corrected time;
b) if two or more or intentional infringements were
incurred, cancel the flight.
c) round the competitor's corrected time to the
nearest 1/10 of a second.
4.3 Points shall be awarded after each race as
follows:
a) the competitor's score is his corrected time in
seconds to the first decimal place;
b) if a competitor fails to complete his flight or
is disqualified the score shall be 240.
4.4 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.
4.5 If time permits, and there is no frequency
conflict, ties for first, second and third place shall be broken by a fly-off race.
