Rules for Scaleauto Endurance Race.
Scaleracing 2018.
Scaleauto Racing Rules.
Introduction to Scaleracing with the Scaleauto cars.
These races are for the Scaleauto Audi R8, BMW M3 & Z4, Jaguar XKR, Porsche 911 RSR, Viper GTS-R and Mercedes SLS GT3. These races are open to all versions of these GT2/3 cars. Including the white kits released by Scaleauto. If using a white kit all major parts must be fitted as on the Factory releases. Small parts such as winglets and mirrors may be omitted as long as the car body meets minimum weight.
These races are also open to the latest Scaleauto GT3 chassis cars, Porsche, Viper and BMW Z4 and the GT3 chassis may be fitted to earlier bodies as long as the body complies with the GT3 version of the rules.
These races are not open to the Porsche Cup or Porsche Rally cars released by Scaleauto.
Other Scaleauto releases will be added once released into the North American market by www.scaleracing.com, no cars will be allowed if they have not been released by www.scaleracing.com.
The racers may only use Scaleauto parts.
A “STOCK” example of each legal car will be available at Technical Inspection if needed as reference for the Race Director. In case of any technical questions the samples will be used to define “STOCK”.
All of the body parts that come with the allowed models as described above must be used. All parts must be fitted on the car and in the correct location. Only exceptions to this is small parts previously mentioned such as mirrors. Inner fenders where fitted must be in place.
Scaleracing Philosophy for 1/24th scale Model Car Racing.
Scaleauto and Scaleracing are determined to create a new philosophy for Model Car Racing in 1/24th scale. A form of racing where the Racer not only desires to perform but also understands it is critical to protect his car from damage. To that end, major body parts must remain fitted to the car at all times during racing. Any repairs MUST BE DONE UNDER “GREEN” CONDITIONS. The track will not be turned off, nor the race stopped to allow a crashed car to be repaired no matter who caused the damage. Drivers must not Marshal cars, and all cars will only be allowed to Pit from a predetermined “Pit area.” All work on cars will be done at the Pit Table in full view of the Race Director; any car worked on in any other area will be disqualified from the race.
MODIFICATIONS.
It is not permitted to modify the RTR car or white kit in any way. (Other than crash proofing as discussed in the Body Rules.)
There are no free parts, all parts must be Scaleauto.
This includes braid, braid clips & lead wires, axles, bearings, wheel inserts, spur gear, pinion gear. Scaleauto braid may be soldered into the brass connector to prevent falling out during racing. Axle spacers may be trimmed to allow correct wheel spacing. At no time (including float) may wheels or tires be visible outside the body when viewed from above.
NO Scaleauto tuning parts other than those found on the “STOCK” cars are allowed.
Early cars can upgrade to ball bearing on the axles. SC-5100 and SC-5118 locking nuts are allowed as well as T Nuts SC-8126A, B, C, D, E, G, H and I to mount the H Plate, and you may tune height on the plate with Scaleauto axle spacers, or similar washers if these are not available.
BODY & INTERIOR.
All bodies and interiors must be painted. The minimum weight for the body with the body mounts and fixing screws attached is: 58 grams for all body styles. The actual body may not be modified, the Scaleauto lightweight parts may be used on all cars running the SC-8000 chassis version of the cars, to lower the weight.
Fantasy liveries in the spirit of 1:1 motor sport are acceptable and encouraged.
Three numbers must appear on the car similar to 1:1 motor sport requirements.
The stock rear wing uprights may be reinforced with rubber glue like Shoe Goo. Also a small piece of foam rubber can be glued to the inside of the rear wing uprights to help strengthen this connection.
It is permissible to use the Carbon/Rubber wings released by Scaleauto for all Events.
Caution, at no time can a car run on track without the rear wing fitted in the correct position. Any car not Pitting under “GREEN” to immediately fix a lost or misplaced rear wing will not be scored while run without the wing. If the car continues to run after warning lap counting will stop until the wing is fixed.
Wing must be refitted in the correct position on the car.
(No modifications of the body, other than the use of Shoe Goo (or similar products) to prevent crash damage, are permitted.)
You can also use Shoe Goo to strengthen the front and rear of the car. Also the side mounts where the body attaches to the chassis. You may also use Shoe Goo to strengthen the fit and mount of the interior. But you may not use Shoe Goo, or any other product to weight tune the body. Any questions on this will be addressed in technical inspection.
It is legal to straighten the chassis and other metal parts. You can also clean up flashing or burrs on parts but cannot file to change the height or shape of parts. Countersinking holes lightly is allowed redrilling or resizing holes is not.
You may set up the chassis to your preferred length as long as no body modification is needed to make your set up work.
CHASSIS.
The chassis and chassis to body mounts must be assembled in exactly the same way as the “STOCK” technical samples. This does include position of axle mounts. Guide lead length and position of the body on the chassis mounts may be adjusted. You may also adjust the wheelbase as long as the body is not altered in any way and that the wheels are centered in the wheel arches.
The chassis must be assembled with all the screws and/or nuts and bolts using the original mounting holes. You may use a thread locking material to prevent screws falling out, but all screws must be tight and fitted as designed.
The chassis plates may be checked to remove burrs and sharp edges. A bent plate may be straightened (flattened), but no chassis may be modified or bent to change its original dimensions.
The original mounting holes can be re-countersunk to allow correct seating of the screws.
The original MSC or Scaleauto logo on the bottom face of the main chassis plate must be clearly visible and the finish of the main plate and all parts must be as supplied from the Manufacturer.
The original chassis plates, parts and metal body holders can not be repainted or refinished in any way.
Note:
Stripped screw holes may be repaired with stud or loctite type products. One area where we have seen damage is motor mounts, it is permissible to countersink the underside of the chassis and mount a screw up to repair/replace the stock screw down into the chassis for motor mounts. We then advise using Scaleauto lock nuts on these mounts from above.
Any other repair should be shown to the Race Director and approved or fixed by repairing or replacing parts.
The length of Scaleauto guide blade can not exceed 29.00 mm. There are several different guide nuts manufactured by Scaleauto all are legal, non Scaleauto guide nuts are not legal. All Scaleauto guides are legal, no modification other than trimming for slot depth.
This includes the profile of the guide, this cannot be altered. You may tape down lead wires, but must use Scaleauto appearing wire, guides, nuts etc..guide shims are allowed . Only one guide blade may be used to locate the car in the slot. No other part of the car may protrude into the Slot at any time. The guide depth may be trimmed if required to prevent hitting the bottom of the slot. Only the minimum needed to prevent this will be allowed. (This measurement can vary from Track to Track and will be decided at the Events)
No part of the chassis may be visible when viewing the car from above.
This includes after a crash, if any part of the car is lost to allow the chassis to be visible it must be repaired immediately under “GREEN” track conditions at the Technical table. (no work will be done when track power is off for lane changes or any other reason)
AXLES, BEARINGS & WHEELS.
Scaleauto “STOCK” steel 3 mm diameter axles front and rear only. No independent front axle set up, however created are allowed.
You may flat spot the rear axle to help prevent the gear and/or rear wheels slipping on the axle.
Stock unmodified Scaleauto bearings as supplied with the approved cars only. All cars may be upgraded to ball bearings on front and rear axle.
Front wheels and tires may be “STOCK” Scaleauto as supplied on the approved cars. The minimum outside diameter of the tire at the beginning of the race shall be at least 26.00 mm and minimum width of 10.00 mm. Scaleauto Foam front wheel/tire combinations SC-2715 may be used. These are supplied 26.5 mm with 8 mm width. The width may not be modified nor profile of the tire changed minimum height 26 mm.
“Stock” tires may be hardened, Scaleauto foam may not be modified or treated in any way to harden or change grip.
At no time may the minimum ground clearance be less than 1mm
Each front tire must make full contact with the tech block with the guide out of play. Only “Stock” Front tires may be hardened and polished and may be glued to the rim.
Rear wheels are subject to Event. For National Finals handout RTR Scaleauto SC-2121 ProComp, Scaleauto SC-2621 ProComp 2, Scaleauto SC 2421 ProComp 3 or SC-2521 Pro Comp 4 wheels with 27,5mm OD, 13.0mm wide.
Rear tires may not under any circumstances be treated with any kind of tire dressing, compound or product.
They may be cleaned with Scaleauto tire cleaner SC-5300 at the Technical Table only.
Once Rear tires have been handed out the car and all tires are under Race Control, tires must be fitted at the Technical table then handed in to Race Control. Anyone removing their car from race control after fitting their motor or tires will be disqualified.
Removing dirt, dust and loose rubber particles from the tires may only be performed with a tape roll if provided by the Race Director, or by using the Scaleauto SC-5300 Tire cleaner.
All four wheels must be fitted with the correct Scaleauto wheel inserts.
The wheels and tires must not protrude outside of the body when viewed from above.
No car can have a front wheel and axle width wider than 78.50 mm or rear wheel and axle width wider than 83mm, measured at the widest point of the front and rear axles. This is the RSR Porsche and BMW.
No matter what the widths of the axles are wheels and tires must remain inside the bodywork at all times.
The goal is to create equal performing cars, tire wise to prevent costs rising due to tire wars.
MOTOR, GEAR AND PINION.
The handout motor will be the sealed Scaleauto SC-0026 can motor with a 12 tooth pinion. Motors may not be broken in or lubricated before the race; all work on motors will be done under “GREEN” while the race is running.
Motors will be dyno’d and lubed before the Event.
Soldering may only be used to attach the lead wires to the motor terminals.
No heat sinks or any other attachment may be used.
Only the stock Scaleauto pinions and Spur gears are allowed 12:44 ratio. They may not be modified in any way from “STOCK” (ratio determined by motor spec’d)
Once a Team has been given a hand out motor the car will not leave the Technical table, it remains under Race Control till the end of the Event.
All work must be then done at the Technical and Pit Table.
Motors can be spec’d by Event organizers, Scaleauto motors only are allowed. At National Finals hand out motors may be used. Another way to spec the cars is to Dyno cars prior to the race; this is decided by Event organizers and should be announced before the Event.
The goal is to create equal performing cars, motor and gear ratio wise to prevent costs rising due to motor wars.
CAR WEIGHT, DIMENSIONS & CLEARANCE. Early chassis cars, type 1 and II.
The minimum weight for a complete Scaleauto car: will be no less than 200 grams with the SC-8000 chassis.
The minimum weight for the complete chassis with sponge tires fitted will be no less than 141 grams for the earlier type 1 chassis and 145 grams for the later type II chassis.
The ground clearance will be measured under the entire RTR car with all four wheels sitting flat on the tech block.
The ground clearance at the beginning of the race can not be less than 1.80 mm at the rear and 1.50mm at the front of the car. The car can not be held up at the front by the braid when checking this measurement.
The ground clearance during and at the end of the race must never be less than 1.mm.
The new Scaleauto GT 3 Chassis cars amendments.
No lightweight body parts can be used.
The minimum weight for a complete Scaleauto car: will be no less than 195 grams with the SC-8003 chassis.
Carbon rear wing and wing reinforcement and body reinforcement rules are the same as the earlier cars.
At no time can the chassis be lower than 1 mm not including spring compression on the front end.
Under compression the chassis must still clear the track by at least 0.5mm. This dimension will not change during the race as front tires do not wear. If due to a crash clearance becomes lower the car must be repaired before re-entering the race.
This is to protect the track surface, make sure your car complies as early Scaleauto GT3 chassis cars came with the front end too low, you can not use the SC-8147C or SC-8147D front axle brackets. Also T Nut above 4 mm may fail tech, it is up to you to make sure there is clearance at all times.
The minimum weight for the complete chassis with sponge tires fitted will be no less than 131 grams for the GT3 chassis.
You can use the tuning springs on the floating front end, but make sure you comply with the clearance rules. Under no circumstance will a car be allowed to run with less than 1.mm clearance, nor with less than 0.5 mm on the front end under full spring compression.
The ground clearance will be measured under the entire RTR car with all four wheels sitting flat on the tech block.
The ground clearance at the beginning of the race can not be less than 1.80 mm at the rear and 1.50mm at the front of the car. The car can not be held up at the front by the braid when checking this measurement.
The ground clearance during and at the end of the race must never be less than 1.mm.
T Nuts and springs are open to all Scaleauto parts, but pay attention to ground clearance even under compression of springs.
No rear motor pods allowed, no sprung rear ends. Only standard set up and tuning of those parts is allowed no additional parts may be added to enhance the GT3 chassis.
All questions must be clarified with the Race Director.
Please remember if it is not mentioned it means it is not allowed.
PIT TABLE:
Once technical inspection is complete and all cars are in “Parke Ferme” this will become the PIT TABLE.
Racers are allowed to bring to the table tools they may need during the Event.
The Raceway will supply power to the table for Soldering Irons and other power tools and there will be Scaleauto Tire Cleaner supplied. All lubricants must be at the Pit Table and in clear view of the Race Director.
At no time after Technical Inspection will any of the Entered Cars be allowed to leave the Track or Technical / Pit area, this is cause for immediate disqualification from the race.
All work on cars including adjusting Braid or oiling car will be done only under “GREEN” and only at the PIT TABLE.
Racers will stop at the Pit Box on the track and a Corner Worker will bring the car to the PIT TABLE. After work the Corner Worker will replace the car on the track.
At all times it is the responsibility of each TEAM to supply a Corner Worker, if any TEAM is found to not be supplying a Corner Worker they will be penalized as follows:
First time is a warning.
Second warning docked 5 laps.
After that they will lose 25 laps per offence.
The SPIRIT of these Rules are to run a fair and competitive Event where all feel they have a chance to succeed. This is a test of the RACER’s more than the car, and while Set Up is important racecraft and tactics are a big part of this Event.
This Event is also to show the value of the Scaleauto Brand, anyone found using non Scaleauto approved parts before the Event will be required to fit the correct parts.
Upon post race Technical Inspection any car found with non “STOCK “parts will be excluded from the results.
Regional and National Sprint and Endurance races will be run under these rules.
