Modern GT Series 2015

Teams and contestants:

For the event a maximum amount of teams allowed is 21.

Every team has to consist out of 2-3 drivers.

Cars and rules:

Modern GT cars will be used, whom during 2010-2014 took part in a race in any of the following races; American Le Mans Series, European Le Mans Series, Le Mans, VLN, Blancpain, 24hr of Spa, Bahrain or Bathhurst. The allowed cars are listed in the Cars List. Plastic bodies as Scaleauto, Carrera and Fujimi for example, will receive a performance break in the form of a reduced body weight to make them the more favourable choice over the GFK bodies. Prepainted bodies are allowed. Only one entry per version will be allowed. For example: one Audi R8 Bilstein, one Audi R8 Playstation, one Audi R8 Post etc.

For each body a specific bodyweight will be in effect, which also translates into the totalweight. In this way the naturally more handicapped bodies will be on the same level as the favourable bodies. The chassis configuration is free, except that it cannot be wider then 70mm.

At each race Bison 2 motors (broken in and tested) and Procomp4 tyres (13 x 26,5 slightly trued) will be handed out to the teams.

The gear ratio is fixed at 14/44 with 26,5 wheel diameter.

A Concours will be held, which is much more relaxed then DTSW for example, but these concours points will still count for the end results of the race.

Points will be awarded as follows:

As there will be nightsessions, a lightkit incl coldcap is needed.

1.14 Any possible form of body weight that moves separately from the body when the        car is on track, is strictly forbidden. This involves any form of construction, too many screws, too soft rubber, too big a lightplug or anything else. The organisers will have the final decision in this matter.

1.15 The chassis parts may only be constructed out of blank, untreated brass/messing. The parts may not be painted, foiled, chromed or have undergone any other form of colorchanging process. Any added weights that are not made out of brass/messing, must be placed 1,5mm higher then the chassis’ underside.

3. MOTOR, GEAR AND PINION

Motor and Gear ratio

2.01 The handout race Motor Bison II ca26000U/18V. The motors will be held in a ‘pool’ and therefore need to be returned after the race. The motor axle may not be worked on and the gear may not be glued on.

2.02 The pignon and spur gear is fixed at 14:44T M50 pitch respectively. Teams must provide their own pinion gear.

Racing will be done on around 16 Volts but at each track will be checked if this will ‘suit’ the cars. This will be done at the very latest on Friday at the start of free practise, or earlier.

4. CHASSIS

Chassis

3.01 Only one part of the chassis is allowed to enter the track’s slot, and this part may not have a longer contact area then 27 millimeters.

3.02 The Guide may be modified by removing material. Adding any material is not allowed.

3.03 Differentials are not allowed.

3.04 Magnets are only present in the motor, and are not allowed anywhere else on/in the car.

3.05 The motor can not be fixed to the chassis with solder.

3.06 The axle gear can only be standard in shape and form. No additional removing weight compared to the original is allowed. Standard for example from Sigma, JP or Scale Auto.

3.07 Only the wires, resistors, plug and LED’s/SMD’s used to illuminate the car are allowed to be in the body. All other parts (capacitor etc) used to power the LED’s/SMD’s must be placed on the chassis.

5. WHEELS & INSERTS

FRONT WHEELS

The front wheels must make contact with the track or techblock over the full 5 millimeters, or more.

The used of cambered front or independently hung front wheels is not allowed.

The front wheels have to clearly show either the blue markings of the ‘hardcomp’, or the white markings of the ‘procomp’ tires of Scaleauto.

Front rims may not be changed in any way except for narrowing them to reach the minimum front tyre width.

REAR WHEELS

Rear wheels are handout Scaleauto ProComp4 wheels, trued to Ø26.3 mm - Ø26.4 mm, 13 mm wide, Ø20 mm inside. Tyre dressing of any kind is not allowed during the official training or during the race. The hand out race tyres may be only be cleaned by using the tape supplied by the OEPS organization.

SPUR

None of the wheels may be visible when looked on the assembled car from above. Spur will be measured over the complete rims left and right.

All 4 wheels of the car must be fitted with 3-dimensional wheel inserts, resembling the wheels of the real 1:1 car, during the entire race duration

Axles

The frontaxle is free, the rear axle can only be made from 3mm solid steel

6. BODY & ACCESORIES

Bodymaterial

Body must be manufactured and/or assembled from one or more of the following materials : molded polystyrene, (i.e. plastic model kits) or molded and/or resin laminated with glass fiber, carbon fiber, or similar materials.

Lexan is allowed for the interior, windows etc., rear wing, diffuser and small add-on parts. Lexan is not allowed to make up an integrated part of the body.

The body must cover all chassis and axel parts, so that no chassis part or axel part is visible when the car is looked at from above. This also includes the guide.

The body must reach the minimum bodyweight by being of roughly the same thickness all over the body. Bodies that are ‘paperthin’ and have all it’s weight centered in the car, will not be allowed. The organisers will have the final decision in this matter.

BODY INTERIOR

Interior must contain at least the following 3-dimensional items :

dashboard,

steering wheel,

painted driver figure with legs,

painted head/helmet combination in a hard plastic material.

Rollbar

BODY EXTERIOR

Front splitter if existing on the 1/1 race car

Rear spoiler

Rear view mirror(s)

Rear diffuser

7. LIGHTS

Functioning lights have to be present at least during the night section. These lights have to be installed on their original 1/1 location in the car.

Front lights: minimum two lights in total, one left, one right, yellow or white color, bright beam.

Rear lights: minimum two lights in total, one left, one right, red color, diffuse light.

Positioninglights are allowed.

ONLY ONE BODY DURING THE RACE

Only one body is allowed to be used for the duration of the race.

ONLY ONE CHASSIS DURING THE RACE

- the wing has to be placed back in it's original position and has to resemble the 'spirit' of the original mounting.

- a repaired, damaged or partially lost wing must be no less than 60mm wide and 5mm deep AT ALL TIMES.

- replacing or refitting the wheel insert(s)

- if the body or any part of the car other then the guide and wheels, touch or risk damage the track.

During night sections, non-functioning front and/or rear lights

- the lights are considered to be non-functioning if less then 3 corners of the car are illuminated for more then half a lap with the exception of braking for a corner.

Unless specifically directed by the race direction, all repairs must be carried out during racing time.

9. GENERAL RACE RULES

No lap will be returned to any team with the exception of:

- the car has passed the counter in a wrong lane and this has been confirmed by more than 1 person.

- the powersupply of the track fails.

If a lost part should cause the track to short or loose power, it will NOT result in laps being given back.

10. PENALTIES

If a car does not pass TC during or after the race by infringing the minimum weight rule, the team will loose 10 laps per gram too light.

If a car does not pass TC during or after the race by infringing the minimum groundclearance rule, the team will loose 20 gram.

(If this ruleset deveates in any way from the german version, the german version is binding)

Procomp 4 Reifen

Messingfahrwerke

Bison 2 Motor

Wir sind in den letzten Jahren die unterschiedlichsten Motoren gefahren. Jedoch war nach unseren Erfahrungen davon keiner über längere Zeiträume sehr zuverlässig. Folglich werden wir zu den größeren wesentlich robusteren 18D Motoren wechseln. Diese Motoren haben sich in der SLP Serie, die vor ein paar Jahren stattfand bewährt.

Mit diesen Motoren sind wir zuversichtlich, dass die Motoren während des Rennen leistungsstark sind ,vor allem sehr identisch untereinander, so dass wir eine hohe Chancengleichheit bezüglich der Motoren gewährleisten können.

Procomp 4 Reifen

Da der Bison 2 Motor schwerer ist, haben wir uns entschieden, die Procomp4 Reifen anstelle der Procomp3 Reifen zu verwenden. Der Procomp 4 ist etwas härter, und verschleißt nicht so schnell, sowie es auch das gesamte Handling der  Autos verbessert.

BOP (Balance of Performance) und bevorteilte Kunststoff Karosserien

Die verschiedenen GT Karosserien werden jeweils ein unterschiedliches minimales Karosseriegewicht aufweisen, welches aus der Fahrzeugliste zu entnehmen ist. Zusätzlich zur BOP werden Kunststoffkarosserien durch 3g weniger begünstigt. Dies ist als Unterstützung für Scaleauto,Carrera oder Kunststoffbausätze Karosserien zu sehen.

z.B. eine GFK/Carbon Karosserie wiegt 23g, dann muss die Kunststoffkarosserie (Scaleauto, oder aus einem Modellbausatz) des identischen Modells nur 20g aufweisen.

Scaleautos Karosserien sind günstig, stabil und sehen gut aus. Durch die Förderung dieser Karosserien wollen wir es einfacher sowie billiger machen, ein schnelles und gut aussehendes Rennauto bauen.

GT

Starting in 2015 the former OEPS organisers will organise a new series, called...

This series will feature modern GT cars.

Pointers:

Bison 2 motor.

Procomp 4 Tyres.

BOP (Balance of Performance) and plastic bodies favoured.

Bodyweight controlled by COG (Center of Gravity) Gauge.

Brass chassis.

Bison 2 Motor.

During the 5 years of OEPS we have run various different motors, but unfortunately none of them have proven to be reliable during long periods of time. Thus we are changing to the larger and much more robust 18D motors. These motors have proven themselves in the SLP series that was held a few years ago.

With these motors we are confident that the motors will be strong throughout the race and most importantly, be very equal to eachother so we can guarantee fair and equal chances for everyone.

This motor is larger and heavier then the motors previously used in the OEPS, and therefore we have chosen to switch to GT bodies, as the LMP bodies simply don’t fit over the Bison2 motor.

Prcomp 4 Tyres.

As the Bison 2 motor is heavier, we have opted to use the Procomp4 Tyres over the Procomp3. The Procomp 4 is slightly harder, and will not wear down as quickly as well as it improves the overall handling of the cars.

BOP (Balance of Performance) and plastic bodies favoured.

The different GT bodies will each have a different minimum bodyweight as can be seen in the Cars list. In addition to the BOP, plastic bodies will be favoured by a reduction of 3 grams in bodyweight. This is support Scaleauto bodies.

For example if a body has to weigh 24 grams in GFK/Carbon, a plastic version of the same body (from Scaleauto or any other model kit) can be 21 grams. The actual weights can be found in the cars list.

Scaleauto bodies are cheap, strong and look very good. By promoting these bodies we want to make it simpler and cheaper to build a fast and good looking race car.

COG Gauge.

New for this year is the COG Gauge. As you can see in the Cars List, each body has a different minimum body weight. In order to thoroughly check it during Tech, we will use the COG Gauge. This is to prevent a team from building a 10 gram body and then put 12 gram down in the body.

The COG Gauge measures how high the Center of Gravity is located in the body. If the COG is too low, weight has to be transferred so that the COG is high enough in the body.

A body will be hung from the COG Gauge using strings, after which the Gauge is hung vertically on a pin. The watergauge on top of the COG Gauge shows if the body swings too far, thus being too low with it’s COG. If a body is correct or higher, the body will swing so far and the water gauge will be in between the 2 lines or higher.

This procedure will regulate the different bodies and weights, so that they will be equal in performance. Also, the so-called ‘paper bodies’ will be a thing of the past. To explain:

If your body is super thin and 10 grams, you have to place another 10-14 grams high in the body to pass the COG Test. If you have a normal body, which weighs 20-24 grams (as per car list) you will not have to change the weight in your body, as the COG Gauge will be set so that if you have built a ‘normal’ body, you will be correct.

This way you will also have a much stronger body. No more paper body ☺

Brass chassis.

The OEPS races saw a variety of different exotic materials used for the chassis. For this new series we have chosen to forbid these and only allow brass. Brass is easy to work with, cheap and available anywhere. So all chassis plates must be blank, not painted, not foiled, not chromed, no exceptions. This is the only way to know that the plate is really brass.
