1/24 SCALEAUTO GT 2019 REGULATIONS - SC-8000 Chassis Cars

 

1.1.0. GENERAL DESCRIPTION

 

(a) The only cars (bodies) permitted to enter are:

(i) The Scaleauto Porsche 911 GT3 RSR (997 + 991). (Not the GT3 Rally or GT3 Cup versions).

(ii) The Scaleauto BMW M3 GT2.

(iii) The Scaleauto Jaguar XKR-RSR GT2.

(iv) The Scaleauto Mercedes Benz SLS GT3.

(v) The Scaleauto Audi R8 LMS GT3.

(vi) The Scaleauto BMW Z4 GT3

(vii) The Scaleauto Viper SRT GTS-R

(b ) It is the responsibility of the racer to ensure that the purchased Scaleauto cars are accurate, complete and without missing parts. (Including small plastic and photo edged parts.)

Please check all RTR pre-painted cars before you buy it for this racing as some of these RTR

Pre-painted cars have been known to be without small parts.

(c) All of the chassis and body parts that come with the Scaleauto cars as described in Art. 1.1.0.(a) must be used. 

 

1.1.1 ALLOWED MODIFICATIONS AND BLUEPRINTING:

a - All chassis parts may be flattened and sanded for optimum fit without lightening or deliberately changing the shape of such part (exceptions to follow).

b - The guide tongue shoulders may be cut to a 45 degree angle from the standard 90 degrees to better suit certain guides types other than the Scaleauto guides.

c - The guide tongue may be bent where it protrudes forward of the T plate to facilitate guide angle and height adjustment.

d - Washers may be used between the T plate and main chassis plate to facilitate height and angle adjustment of the front axle and/or guide.

e - The plastic mounting posts inside the body may be trimmed and/or washers may be added

between the posts and metal body mount plate to facilitate body height adjustment and alignment.

f - The motor mount may have the slot in it changed to help with gear mesh and motor line up.

g - The motor mounting bolt may also be replaced with a countersunk bolt fitted from the bottom of the main chassis plate. This will require the hole to be drilled out and countersunk to make sure the bolt head does not affect the ride height measurement.

h - The forward face on the rear axle carriers may be shaped to allow the motor to be move closer to the rear axle. This is intended to get a more sidewinder fit especially when using the 10T pinion where required.

i - Parts of free make are restricted to: (i) nuts, bolts, spacers and washers, (ii) the guide, guide nut and washers, (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).

j - Scaleauto 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 Scaleauto car is 190.0g.

(b )The minimum weight for the body with the body mounts and fixing screws attached is 55.0g.

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

(d) - The chassis 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 1.4mm (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) - The ground clearance for the body will be measured with the body attached to the chassis as it will be raced.

(g) - The body ground clearance at the start of every race is never less than 1.4mm.

 

(h) - Additional weighting of the body can be applied anywhere on the inside of the body or on top of the metal body mounts.

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

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

 

1.1.3. CHASSIS SC-8000 (only non-drop arm non-front suspension 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. The latest chassis may have a magnet box fitted just in front of the motor. Please remove this box and magnet completely. The remaining opening in the chassis may be filled in if the driver chooses to do so. This filling may consist of any non-magnetic material.

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

(f) 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.

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

(h) The alternative aluminium H-plate is legal as sometimes the chassis are shipped with them and other times with a steel version.

 

1.1.4. MOTOR, GEAR AND PINION

(a) The motor will be limited to the following:

Scaleauto SC-0026 Endurance Motor (with complete can wrapper attached).

(b) Soldering may only be used to attached the lead wires to the motor terminals.

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 can be the standard hard rubber wheels with rims as supplied with the RTR

cars with a minimum starting diameter of 26.3mm. Scaleauto parts SC-2715P or SC-2709P may be used with a minimum starting diameter of 26.3mm.

Plafit part 812106-RTR may be used with a minimum starting diameter of 26.3mm.

(d) Each front wheel must make minimum 6.0mm of contact with the tech block with the guide out of play. Front tires may be hardened and polished.

(e) Rear wheels are RTR Scaleauto SC-2421P ProComp 3 wheels with a minimum 26.5mm OD, 13.0mm wide. Plafit part 812112-RTR or 812113-RTR may be used with a minimum 26.5mm OD, 13.0mm wide. Altering the rear wheel diameter will not void the minimum starting ride height as per rule 1.1.2.(d).

(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.

(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 Scaleauto 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 Scaleauto. 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 Scaleauto 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.

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 Scaleauto 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).

(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 fitment of the Lexan window. The Viper Lexan interior has a vent moulded under the rear window. This vent is to tall and will need to be cut down for the interior to fit properly.

(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.

(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.

(f) The Viper RTR white kits are supplied with two front grills. If using the open one, then the

relevant photo edged part must be used. The RTR white kits are also supplied with two wings, the rubber wing mounts supplied may be used with the relevant wing.

(g) 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).

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

(i) Event organizers must provide all actual scrutineering tools for the event at the start of official practice. These tools must include a scale measuring to at least 1/10th of a gram, specific callipers or gauges for measurement of the front and rear spur and specific callipers or gauges to measure the minimum front wheel diameter and width. Specific gauges to measure ride height before, during and after the race must also be provided at this time. These tools will be the only tools that will be used by the scrutineer (s) during the event.

Any items/issues not mentioned, covered, or arising is not permitted.

Pre and Post Race Scrutineering conditions apply for all cars within all classes.

Any vehicle that does not comply with the above rules or that is deemed to be not within the spirit of these rules will be excluded.
