The GPd2013 is an invitational four race proxy event for 1966-68 Grand Prix cars. The rules for the event are intended to promote the building of cars that are beautiful, accurate to scale, represent the cars as they raced and are fast. All of the races will be staged in the UK this year. Concours judging will be included in the event. Points earned in Concours will be added to the entrant’s overall score and be counted the same as one race. Any car that competed in an International Grand Prix Championship race from 1966 to 1968 is eligible. Front and rear wings are not permitted although it is recognized that many of the 1968 prototypes had wings by the midpoint of the 1968 season. More to follow.

GRAND PRIX CARS
Any car that competed in an International Grand Prix Championship race from 1966 to 1968 is eligible. A list of eligible cars will be provided. Front and rear wings are not permitted although it is recognized that many of the 1968 prototypes had wings by the midpoint of the 1968 season.
1. SCALE, DIMENSIONS & GENERAL APPEARANCE
All cars are to be accurate 1/32 scale representations of the full size car. As most racers rely on manufactured bodies, which are not always perfect, there is no specific requirement for exact scale length and width for body shells. Cars are expected to be reasonable to scale. Wheelbase and Track measurements must be 1/32 scale within + or – 2mm. “Wheelbase” is the distance between the center lines of the front and rear wheels. “Track” is the distance between the center lines of the left and right hand wheels at the front and at the rear of the car.
No car should exceed the maximum width of 58mm.
Cars will be measured over the outside width of the tires.
It is the entrant’s responsibility to prove the accuracy of any car. The entrant may and is encouraged to provide a photograph of the actual car upon which the entry car is modeled. If there is any doubt the scrutineer may disqualify the car or assign a handicap. The scrutineer’s decision is final.
The general appearance of the cars will be taken into account at the Concours judging. Should an entrant present a car that looks out of ‘character’, there will be an adjustment in the Concours ranking as determined by the judge.
2. BODIES
All body shells must be of hard plastic, glass fiber, resin, wood, metal or similar material. Vacuum formed bodies are not permitted.
All cars must carry at least two racing numbers which are period correct. The entrants name should be clearly marked on the bottom of the chassis.
All cars must have clear windscreens fitted where they appeared on the prototype. Vacuum formed windscreens are permitted.
All cars must carry detailing including but not limited to mirrors, roll bar, suspension (which includes shock absorbers when visible and A arms or rocker arms as appropriate) and external engine components and differential consistent with the car being represented.
All cars must have a suitably decorated and period correct, three dimensional, representation of a driver consisting of at least a head, shoulders, arms, hands and the upper part of a steering wheel. Vacuum formed interiors and drivers are not permitted.
The chassis, motor and all running gear should not be visible from above or through the cockpit opening and engine bay unless that which can be seen represents parts of the real car, e.g. suspension components and exhaust systems.
The slot guide must not protrude beyond the front-most point of the car when in the straight-ahead position.
3. WHEELS & TIRES
All wheels must be representative of real wheels or have suitable inserts fitted.
Tires are limited to rubber or urethane compounds. Silicone tires and sponge/foam rubber tires are not permitted.
All tires must be dry and free from additives whenever the car is placed on the track.
• Front wheels and tires: Minimum diameter 18.5 mm, minimum width of 6mm at the bulge. (Overall width)
• Rear wheels and tires: Minimum diameter 20 mm, maximum width 11.5mm at the bulge. (Overall width)
4. MOTORS & CHASSIS
Motor choice is free. If the motor fits inside the car, you may use it. Motor orientation is inline only.
Races will be run at 12 volts.
Chassis design and construction is free but must comply with sections 1-4, however plastic and carbon fiber chassis, whether purchased or scratch built, are not permitted.
Any chassis design which allows the wheelbase or effective track dimension to vary will be measured at both extremes of movement and must remain within the + or - 2mm scale tolerance and not exceed the maximum width restriction.
Wheelbase, track and overall width will be measured with the steering in the straight-ahead position for any cars fitted with steering.
Minimum ground clearance of 1/16” will apply under the motor and the entire length of the chassis and body. Drive gears may be below the minimum ground clearance but must, at all times, remain clear of the track surface.
One slot guide only is permitted. Blade designs must be no more than 25mm long.
Traction magnets are not permitted.
READY-TO-RUN (RTR) CARS ARE NOT PERMITTED.
The final decision on eligibility will rest with the event organizers.
CONCOURS D'ELEGANCE The organizers will determine the method of judging. Each entrant may supply a reference photograph of the car being represented.
The cars will be judged and ranked using the following guidelines. I .The model provides an immediate impression of the original car in miniature. 2 The car sits well on its four wheels when viewed from eye level. 3. The inclusion of suspension detail 4. Incorporation of body details 5. The wheel details 6. The detailing of driver and cockpit. 7. The quality and neatness of chassis engineering/construction. 8. Paintwork, general finish, lettering, authentic colors and neatness. 9. The amount of personal ingenuity that goes into the model may result in higher marks.
Event Scoring Places 1-10 for each race as well as for the concours judging will earn points as follows:
First 25 Second 22 Third 20 Fourth 18 Fifth 16 Sixth 14 Seventh 12 Eighth 10 Ninth 8 Tenth 5
Therefore the maximum number of points an entrant could earn would be 125 (first place in all four races AND coming in first in the Concours judging) There are no points for fastest lap in any race. Scrutineering Violations/Penalties Exceeding Maximum Width of 58MM: The % of excess will be deducted from the points earned in the races For example: Car is 62MM wide. 4 mm over the maximum of 58MM or 7%. If the entrant earns 75 points during series (excluding Concours) the deduction is 5 points (7% of 75) for an adjusted total of 70
Exceeding Maximum Track or Wheelbase (plus the 2mm) tolerance The % of excess will be deducted form the points earned in the races For example: Car has a 79mm wheelbase. The 1/32 Scale wheelbase was 75mm with a + 2mm tolerance. The car is therefore 2mm over the allowed limit of 77mm or 3%. If the entrant earns 75 points during the series (excluding Concours) the deduction is 2 points (3% of 75) for an adjusted total of 73.
The same methodology will be used for any excesses on tire/wheel measurements and ground clearance height as noted above. In other words, we will calculate the % of difference from the requirement and deduct that % from the total of points earned in the 4 races) Late entries (cars that arrive after the deadline date of September 15, 2013) The entrant will be responsible for any additional costs incurred by the hosts/organizers for mailing his car to the next available venue If an entrant misses a venue race date, he obviously forfeits the points for that event. Note: Entry edited on 9/20/2013 to add event scoring and Scrutineering rules. Mark Huber

Here are the four tracks that will host the races in the GPd2013. These photographs will give you all an idea of the type of chassis and set up required for this series. Pete Shepherd's superb 1960s American themed circuit. This is painted Carrera track. David Lawson will host his round at the Southend Slot Racing Club track. This a wooden routed track. Dave Wisdom's superb typical UK circuit from the 1960s/early 1970s. This is a wooden routed track. These three pictures are of Dave Jones great circuit in the style of a club he raced at in the 1960s. This is a wooden routed track. David

So all I need do is figure out how to build a car that will shift into 6th gear only at Southend!

EM, when we had the Dave Jones F1 Proxy a few years back we used Dave Jones track and a couple of others that were similar to Dave Wisdom's and Pete Shepherd's as well as the International track at Wolverhampton which is similar in size to the Southend track so the cars had to contend with the same track size variation then.
The Southend track was used for a round of the IPS in 2011 and those NC1/NC8 powered cars were very rapid despite the regulation low powered motors.

I should be able to at least make a good showing at the long track then, if it is similar to Wolvs ! My IPS Lotus won there.

It was just my attempt at morning humor. I do have a motor in an Eagle that contested last year's GP de G. Apparently it was fast enough to achieve low earth orbit but also suffered from a severe deficiency in the retardation department. So it is not a good candidate. I have been contemplating a Matra MS 10 shell for several weeks. The only thing that I can say at this point is that a Slot It flat six will not fit. Oh-– one more thing: although my VRAA entry did not fare well last year there was one interesting result. Contrary to my usual practice I used a plastic crown year (64 DP) with some trepidation. It survived with no observable wear it is very small and helps to get around the problem, with the 60s cigar tube cars, of finding a way to keep them from looking like a penny farthing bicycle running backwards.

Is there a preferred tyre?
Perhaps the track owners could advise on which tyres work best on their circuits?
With kind regards,
Russell

Very nice tracks! I like these great detailed home tracks with their special spirit! But right: it will be difficult to find THE right setup for all four tracks.
Is there any evidence about the event data? It might be, that I could manage to come as a visitor.....

Hi Taffy, Good to see you posting again. David Lawson kindly agreed to coordinate the race events in the UK with his colleagues, so I"m leaving it in their hands to determine the sequence and dates of the races. As you know, the entries will be due in the UK by September 15, and we've promised to have the cars on their way back to entrants in December. From what I've learned about German holiday time, the 9 weeks between mid -September and mid-December would only account for about half of your annual leave, so why don't you plan on spending the entire time in England? Very best regards,

Russell Pete Shepherd writes, "My idea for the track was to recreate a typical track from the west coast in the early to mid 1960's. I've used mainly Monogram figures, buildings and accessories which were made in that period so are perfect. The track was primed and then received a coat of emulsion paint, which offers superior levels of grip over normal Carrera track. I'd say Urethane's work well and are better than untreated rubber. The track has DS lap timing".
Ortmann's, NSR and Slot it tyres all work well at the Southend track.
EM I knew it was your dry humour but I also tried to give some insight about the tracks in my reply.
Taffy As Mark says we haven't got exact dates yet other than starting in the third or fourth week of September but we will let everyone know when he have the final timetable.

A clarification, if you will....
Must an entry represent a specific car, livery and race number in a specific historic event? Or, are race numbers and even liveries "open" as long as the car was raced by somebody in F1 during the defined period?
