If a part is shown in these pictures it must be on the car according to the manufacturer's intended mounting and location. The only exceptions are as follows: Art. 1.1.3. (b ).

 

1.1.1. MODIFICATIONS

(a) It is not permitted to modify the RTR car or white kit in any way other than those parts of free make as described by Art. 1.1.1 (b )

(b ) Parts of free make are restricted to: (i) nuts, bolts, spacers and washers, (ii) the guide and guide nut, (ii) braid, braid clips & lead wires, (iv) axles (v) axle bearings, (vi) ballast lead weights, (vii)3 dimensional wheel inserts, (viii) M50 spur gear, (ix) M50 pinion gear (check on correct size for the proposed hand out motor).

(c )Scale Auto tuning parts including the carbon H-plates, spring plates, guides holders, different height axle holders, carbon rear wings (excluding the wing supports) etc. are NOT permitted.

 

 

1.1.2. WEIGHT, DIMENSIONS & GROUND CLEARANCE

 

(a) The minimum weight for a complete Scale Auto car is 190g.

 

ScaleAutoTotalminweight.jpg

 

(b )The minimum weight for the body with the body mounts and fixing screws attached is 55g.

(c) The ground clearance will be measured with the guide out of play so that all four wheels sit flat on the tech block.

(d) The ground clearance at the start of every race is never less than 1.8mm.

(e) The ground clearance during or at the end of any race is never less than 1.40mm (if found to be in breach during the race, it must be rectified under green - if after the end of the race; it will result in the loss of the total laps scored in the best race bracket during the race).

(f) Additional weighting of the body can only be applied to the vertical surfaces of the plastic reinforcing strips within the boundaries as shown in this picture.

(g) The distance from the top of the H plate to the bottom of the chassis plate is never more than 4.0mm.

(h) Additional weighting of the chassis may only be on top of the chassis, NOT visible when viewed from below.

 

1.1.3. CHASSIS (only non-drop arm version).

 

(a) The chassis must be assembled with screws and/or nuts and bolts using the original mounting holes.

(b ) The chassis must be assembled in the exact manner and orientation of the production RTR car. In this instance it is noted that some RTR cars are shipped with the guide holder mounted below and other above the T-plate. It is therefore up to the racer to decide which position he prefers for the guide holder on his car.

(c) The chassis plates may be flat sanded to remove burrs, sharp edges and swelling.

(d) The original mounting holes can be re-countersunk to properly seat the screws.

(e) The original MSC/Scale Auto logo on the bottom face of the main chassis plate must remain visible to the Technical Control.

(f) The original chassis plates, parts and metal body holders cannot be repainted or refinished in any way.

(g) The length of the guide blade cannot exceed 27, 0 mm and this guide blade is the only part of the chassis that may enter the track's slot.

(h) No part of the chassis may be visible when viewing the car from above.

 

1.1.4. MOTOR, GEAR AND PINION

 

(a) The handout motor will be decided by the event organiser, but will be limited to the following:

 

Scale Auto SC-26 Endurance or the NSR 25000 Evo.

 

IMGP3020.jpg

1.1.5. AXLES, BEARINGS & WHEELS

 

(a) Only solid steel 3 mm diameter axle's front and rear are permitted. No independent front axle configurations of any kind are permitted.

(b ) Ball bearings for 3mm axles are permitted.

(c) Front wheels must be either the standard hard rubber wheels with rims as supplied with the RTR cars or a minimum diameter of 26.5mm when using the RTR Scale Auto SC-2715P (26.5mm OD, 8mm wide) racing wheels.

 

IMGP3017.jpg

 

(d) Each front wheel must make minimum 7.5mm of contact with the tech block with the guide out of play. Front tires may be hardened and polished.

(e) Rear wheels are RTR Scale Auto SC-2421P ProComp 3 wheels with 27,5mm OD, 13.0mm wide. At events where handout wheels and tyres are supplied, the hand out wheel and tyre diameters may not be changed and must be used as supplied. At events without hand out wheels and tyres, the rear wheel diameter may be altered, provided this Scale Auto part as quoted, is used. Altering the rear wheel diameter will not void the minimum starting ride height as per rule 1.1.2. (d).

 

IMGP3018.jpg

 

(f) Rear tires may not under any circumstances be treated with any kind of tyre dressing, or compound or traction product.

(g) Removing dirt, dust and loose rubber particles from the tyres may only be performed with a tape roll or Shellite provided by the Race Direction.

(h) All four wheels must be fitted with three-dimensional wheel inserts (with or without brake discs and callipers) correct to the car. (No photo edged or vinyl cut reproductions will be allowed).

(i) The wheels may not protrude outside of the body when viewed from above.

1.1.6. BODY & INTERIOR

 

(a) All bodies and interiors must be painted. (Interiors with at least three different colours and bodies with at least a coat of clear paint covering the complete outside of the body shell).

(b ) Fantasy liveries in the spirit of 1:1 motor sport are permitted.

(c )Three number shields typical of 1:1 motor sport are required.

(d) The stock rear wing uprights only may be replaced or reinforced with rubber parts of equal or like shape. The Scale Auto Carbon Rear wing may not be used, but the rubber wing mounts supplied with these wings may be used. (Should a wing go missing or get broken beyond repair a replacement part may be purchased as long as it is the original part as sold by Scale Auto. For example the BMW part number is SC-7612 and the Mercedes is SC-7614 etc).

(e) All the cars are permitted to use the full Scale Auto Lexan window and interior kits. Only the roll cage from the original hard plastic interior must be refitted to the lexan interior.

(f) Mirrors and wipers on some cars are very fragile and cars will be allowed to race without them when it is obvious that the mirror(s) has broken off. Drivers are encouraged to present cars with mirrors and wipers at the start of all races

(h) No modifications of the body are permitted other than those described by Art. 1.1.6(a-e)

 

 

1.1.7. ADDITIONAL NOTES & CLARIFICATION TO RACERS.

 

(a) Metal body mounting brackets SC-8117 can be used in place of the plastic part as first shipped on the Porsche 911 RSR GT3 cars in early 2010.

(b ) Only Scale Auto lexan interior and window kits may be used where allowed. (The air vent - photo below - that comes with the Audi lexan window and interior kit is not allowed).

 

IMGP3006.jpg

 

(c ) The gas filler caps in the Mercedes that are molded into the lexan windows should be trimmed away so that the original plastic filler caps are used. This principal will also apply whenever a lexan part may be moulded with corresponding external body parts restricting the figment of the lexan window.

(d) When fitting the lexan interior the legs of the roll cage may be shortened to be able to fit it into the space between the lexan interior floor and the roof of the car. Currently this is only the case on the Mercedes SLS.

 

ScaleAutoMercLexanProb1.jpg

 

(e) The BMW Z4 white kits are supplied with four small front winglets, these may be used at the discretion of the builder. The body kit is also supplied with two different rear wing mounts. Either of these may be used. However, if the mounting legs are replaced with a flexible material, the secondary wing between the mounting legs must be retained.

IMGP3043.jpg

 

(f) Racers are warned that cars with missing parts will not be allowed to enter. (Even if it was lost during practice or on the way to scrutineering).

(g) During lane changes no work on the cars at all will be allowed - work on the car may only be done under green.

 

END.

 

 

 

 

Hi guys,

 

THESE REGULATIONS ARE NOW LOCKED FOR 2013. THE ONLY CHANGES FROM NOW ON WILL BE WHEN NEWLY RELEASED CARS HAVE BEEN PARITY TESTED FOR INCLUSION IN THESE REGULATIONS OR WHEN ANY SPECIFIC PART IS REPLACED BY SCALE AUTO WITHOUT NOTICE. THESE AMMENDMENTS (if required) WILL ONLY TAKE PLACE AT THE END OF MARCH, JUNE AND SEPTEMBER 2013. THESE TYPES OF CHANGES WILL ALWAYS BE SUBJECT TO AVAILABILITY OF CARS AND PARTS TO EVERYONE RACING IN AUSTRALIA - AVAILABILITY ON THE WWW WILL BE CONSIDERED ACCEPTABLE. Please keep an eye on the discussion section of this forum for any developments that may impact on possible regulation changes.

 

Thank you for participating in the formation of these regulations making this the great class it is!

Hi guys,

 

Some clarification has been requested regarding the loss of parts during a race. In other words, should these parts have to be put back on the car, or not.

 

Obviously there are a number of options, but let me point out the following:

 

- these regulations as published do not specify 'Sprint' or 'Endurance' racing - this distinction is important when trying to answer the question.

 

- during sprint racing it is generally accepted that cars are allowed to complete the race bracket without a lost part, provided it's loss does not interfere with other drivers/cars or is damaging the track.

 

- during endurance racing it is normally accepted that cars must be stopped and repaired - under green - before they are allowed to continue. The only parts that are generally not expected to be 'put-back-on' during the race, are aerials, mirrors and wipers. After all we never see cars in 1:1 having to return to the pits for these minor parts, but certainly for wheels (in our case wheel inserts are considered as 'the wheel') splitters, wings and diffusers.

 

Finally, please remember that cars may be scrutineered at any time and must always be in accordance with the car regulations as published.

 

Suffice to say, organisers of race events should make it quite clear (at least during the drivers briefing) what the expected procedure will be during the event and let everyone know what is expected when parts are lost from a car during the race.

 

Cheers,

 

Jan
