Race Procedure

Qualifying –

· Qualifying will be run in reverse order of entry. Each entrant will be given a timed

run to record their fastest lap which will determine their starting position in the heats.

See class rules for details of time allowed.

Format –

· All entrants will contest a series of consies, heats, quarterfinals, semi-finals and final

dependant on the number of entries.

· All races designated as “consies” will be contested over 4 lanes only, running on

either the red set ie. red, green, blue, purple or the black set ie., black, yellow, orange,

white. All other races will be contested over 8 lanes.

· All races will be on a “move up” basis. The following schedule has been adopted to

ensure that a minimum of four drivers will move up from each race. See class rules

for heat and lane change times.

· 1 to 8 entries: Final only

· 9 Entries: One heat and final. Fastest qualifier into final – top 7 in heat move up.

· 10 to 16 entries: Two semis and final Top 4 in each semi move up.

· 17 to 20 entries: one heat, two semis and final. Fastest 12 qualifiers into semis – top

4 in heat move up.

· 21 to 24 entries: Two heats two semis and final. Fastest 8 qualifiers into semis – top

4 in each heat move up.

· 25 to 32 entries: Four quarterfinals, two semis and final. All entrants start in

quarterfinals – top 4 in each move up.

· 33 to 36 entries: One consie, four quarterfinals, two semi and final. Fastest 28

qualifiers into quarterfinals – top 4 in consie move up.

· 37 to 40 entries: Two consies, four quarter finals, two semis and final. Fastest 24

qualifiers into quarter finals – top 4 in each consie move up.

· 40+ entries: Fastest 16 qualifiers into quarterfinals. All other drivers will be seeded

into a number of consies with the top 4 lap scorers in each consie moving up to the

next stage in the race schedule.

· Lane choice will be determined by either qualifying position or position from

previous heat.

Lap Counter –

· The “Johnson Racing Systems” computer system (Version 4.0) will be used for all

events. This system incorporates the following unique features which drivers must be

aware of.

· Rider Detection – The system will implement an automatic “track call” if it detects a

lap time shorter than a pre-programmed time delay and the lap is not counted. This

time delay is usually set to 1/10th of a second shorter than the fastest qualifier. Cars

which cross the lap counter on the wrong lane causing such a “track call’ will be

replaced on the correct lane immediately before the lap counter, thereby eliminating

any gained or lost laps. Drivers should also be aware that the system treats each

bracket as a continuation of the preceding bracket. Therefore if a car is moved

forward on the track during a lane change it will trigger a short lap “track call” when

it crosses the lap counter. If this should happen then the offending car will not be

credited with the lap and will restart from where if stopped. This is effectively a one

lap penalty for cheating on lane changes.

· Short Lap – Drivers should be aware that the “JRS” system treats each bracket as a

continuation of the preceding bracket. Therefore if a car is moved forward on the

track during a lane change, it will trigger a “Short Lap” when it crosses the lap

counter. If this should happen then the offending car will not be credited with the lap

and will restart from where it stopped. This is effectively a one lap penalty for

cheating on lane changes. Caution: drivers should also be aware if their car has rolled

on excessively at the end of a lane change, this could also trigger a “Short Lap” and

thus the offending car will not be credited with the lap and will restart from where it

stopped.

· Time Factor – At the end of the last bracket for each race all cars must continue until

they cross the lap counter. As each car crosses the lap counter the power of their lane

is shut off by the computer. This eliminates the need to take footage and means that

all positions on the computer are correct at the end of racing. Each car is given a time

factor which is the time from when the bracket expired to when the car crossed the lap

counter (accurate to 1,000th of a second). Drivers must be aware that the race does not

finish until they cross the lap counter or a maximum of 10 seconds expires.

Track Calls –

· Track Calls will be initiated only in the following circumstances – Automatic rider

track call; Cars off in main straight, bank or bridge, unmarshalable car; A marshal has

too many cars off to cope with; Marshal not in position; Track fault.

· It should be noted that the intention of the race director will be to maintain fair

racing conditions.

Clearance will be measured with front and rear tires sitting flat on the test block without the guide.

9 Axles (Front & Rear): 3/32” (2.38mm) minimum diameter, solid steel. Hollow axles are not allowed. Axles may only

be flattened in the areas where the wheels and gear are secured.

10 Bushings/Bearings: Oilite/bronze bushings only. No ball bearings are allowed in the front or the rear.

11 Minimum Weight: 100 grams ready to race.

12 Drive Type: Inline drive only, with the motor shaft at 90° to the rear axle.

15 Maximum Rear Body Height: 1.375” (34.93mm) measured with the car on all four wheels on a tech block (unsupported by the guide flag), from the tech block surface to the top of the highest point of the rear of the body,

excluding any add-on spoiler. Severe raking of the body for aerodynamic effect is not allowed.

16 All chassis parts, including the guide flag, must be covered by the unmodified body.

17 The wheels shall be located in relation to the wheel arches in the body.

18 Tyres – Rear: Any commercially-available black natural rubber tyre, chemically-treated or untreated, on any size

hub.

Only WD40 or Lighter fluid can be used to clean the tyres. No “Goo” permitted. No chemical treatment allowed

except by manufacturer as previously mentioned.

Competitors found using “goo” or other chemical treatments to enhance the traction qualities of the tyres may receive a penalty not exceeding 25 laps. Such actions are deemed to be contrary to the spirit of the nature of vintage racing. Tyres are to purchased at a reputable supplier, and may be glued on the rims and ground to size. Please observe this rule to make it fair for all that compete.

19 Tyres – Front: Must be made of two pieces, i.e. a wheel and a tyre. Front wheels may be made of any material and

can have any size hub (as long as the front wheel and tire dimensions listed elsewhere in these rules are observed).

Must be glued to the wheels and be made of black rubber.

May be coated with cyanoacrylate adhesive (“Super Glue”) or nail polish.

Must contact the track surface before any part of the chassis when car rocked from side to side.

 

Chassis

1 Chassis Type: Any personally built or commercially available scratch built chassis in kit form or built conforming to

these specifications is allowed.

2 Chassis Materials: Brass: sheet, rod, and tube; steel: wire, pin tubing, and commercial guide tongues are allowed.

Steel tongues cut from center sections of Flexi chassis, such as Parma Flexi 2 or 3, JK Cheetahs, etc., may be used

until January 1, 2009, but cannot be cut off any farther back than 3/8” (9.53mm) behind the front axle and are limited

to a maximum 1” (25.4mm) width. Other pieces of steel used for guide tongues are limited to a maximum 1”

(25.4mm) total width and 1.50” (38.1mm) total length. No other materials are allowed. Chassis parts, such as pans,

brackets, guide tongues, etc., that are made using EDM, laser, or water-cutting techniques are allowed only if they

are individual commercially available components or components of chassis kits (i.e. these techniques may not be

used in the private manufacture of one-off components). Materials such as printed circuit boards are not legal.

Each car must have a brass rear bracket consisting of at least three sides (vertical or horizontal), with each

connected side having a minimum width or height of at least .200″ (5.08mm). The motor bracket must support the

motor and extend to touch the rear axle tube.

Rev: 081002a Page 1 of 3

 

The axle tube does not need to travel through the motor bracket. The motor can be screwed to the motor bracket

and/or soldered in place. Floating pin tubes inside another tube are allowed.

3 Tape/Lead: Lead weight may be added to a chassis but may only be affixed to the topside of the chassis. Strapping

or other tape to control or restrict movements is allowed but may only be affixed to the topside of the chassis.

4 Hinged Movements: Other than a drop arm, all hinged movements must be oriented in only one direction on any

individual chassis. A chassis may have transverse hinges (examples: Iso-fulcrum hinges and plumber hinges) OR it

may have longitudinal hinges (example: side pan hinges) but the chassis may not have both types. The number of

individual hinges is not restricted. Centerline hinges are NOT allowed.

5 Front axle: A single straight, 3/32” (2.38mm) minimum diameter, one-piece front axle is required, carrying both front

wheels. The axle may be fixed or in a tube. NO hinged front wheel movements are allowed (i.e. no “L” arms).

Front wheels may rotate independently.

6 Guide: A single guide flag is allowed, centered on the longitudinal axis of the chassis (i.e. no sideways “free float” or

offset) and with a blade no larger than .086” (2.20mm) wide x 1.060” (27.18mm) long.

7 Guide clips may be used.

8 Any lead wire may be used.

9 No part of the chassis, motor, gear, or other component may hang below the main chassis rail(s), which may not be

bent or bowed vertically for the purpose of lowering the midsection of the frame below the level dictated by the

clearance specifications.

 

Motor

1. Motor: Plafit Cheetah II&IV only to be used, and must remain unopened and unmodified.

2. Exclusion Clause: Clear violation of the motor-tampering rule may result in permanent exclusion from future Aussie

Retro events of any kind.

3. A motor may not be changed after tech inspection at any time unless it fails during the race. A motor change between

heats is NOT allowed unless the motor change was begun during an active heat. Motor changes must be approved

and re-inspected by the Tech Director.

Body

1 All approved Can-Am bodies are listed in the “Approved Body Lists” section. All bodies must be representative of

pre-1970 cars. Note: It is requested, in keeping with the spirit of retro racing, that bodies not be any less than .007”

thick on the sides. Any body found to be flimsy or a detriment to marshaling will need to be corrected by the racer.

Tape or body armor may be used to achieve the desired side thickness.

2 An entrant may only use one body per class.

3 Body style: Racers are encouraged to present cars with scale realism. Bodies must be those on the approved body

list. No “flattened” or “aerodynamically-improved” bodies allowed (i.e. no molded-in spoilers, wings, etc., that were

not on the original full-size car or original mold). Note: molded-in spoilers may not exceed the allowed specification

governing the maximum width of the body. Front wheel arches must be cut out. Rear wheel arches may be left closed

if the original full-size car ran with closed wheel arches. Bodies must be presentably-painted and carry at least three

racing numbers, one on each side, and one on the front and not less than ½” (12.7mm) in height.

To further clarify this regulation, all bodies must be fully opaque on all sides except for those areas deemed to be

windows. Windows may be tinted.

The term opaque means covered by paint, tape, or other suitable material such that a finger is not visible through the

paint or other covering under normal lighting.

No part of the chassis may be seen when looking down on the car from above. Legal openings, such as air vents,

etc., may be cut out. There should be a minimum 1/16” (1.59mm) vertical component and/or part of the grill along the

front edge of the body unless this element was not on the original car (example: Ti22).

4 Bodies may be reinforced with tape and/or other suitable materials.

5 Spoilers and Air Control: A single, flat plastic spoiler set at any angle may be added to the rear of the body only.

The spoiler’s length is limited to a maximum of 1/2” (12.7mm) from the rear edge of the body and must be no wider

than the outer edges of the body. No additional bends are allowed except for the one used to set the initial angle.

No side dams of any type are allowed. Front diaplanes are not allowed. High-mounted wings are allowed if they are

used on the original full-size car. Such wings must be securely attached to the body and/or chassis.

6 Cockpit: All bodies must carry a painted (at least three colors), fully-molded three-dimensional interior comprising a

driver (helmet, shoulders, and arms), a steering wheel, and cockpit representation. No paper interiors.

If a Can-Am body does not have a molded-in driver, then the body must be totally cut out so the interior is in full view.
