Some of you may be familiar with the VRAA Proxy Race for 1961-65 Grand Prix cars. It is raced on a mix of wood and plastic track across the USA and Canada and is now entering its seventh year under the current formula. For the coming season, I have inherited the management of the series and have posted the updated Rules and Entry Registration on the SCI Forum where the race is hosted and most of the discussion about the event takes place. For those who may never browse there, I will give you a condensed version of the rules here:
VRAA CAR CONSTRUCTION RULES
Entries must be 1/32 scale model slot cars of F1 cars from the 1961-65 1.5 liter period.
Car Body Construction and Appearance:
Only hard bodies (wood, resin, fiberglass, injection molded plastic, or fabricated plastic) will be allowed.
Entries must be a reasonably scale representation of a specific, historical Formula One car, in its authentic livery, as it raced or practiced for an FIA Championship F1 Grand Prix during the 1961-1965 period. The historically accurate race number is not required. All entries must race with the race number pre-approved by the Race Director during the Registration process. Fantasy paint schemes and fantasy cars are not permitted.
As a minimum, all entries must include the following modeled detail: a period-appropriate driver with head, arms, hands, and partial steering wheel; period appropriate wheel inserts; and, except where not present on or visible from the exterior of the actual car, clear windscreen, roll bar, some 3-D engine detail, gearbox, exhaust system and mirror(s). A reasonable attempt to model the suspension detail of the actual car -- at minimum, upper and lower “A-arms” and radius rods, if present -- is required. See-through interiors -- where the track can be seen when looking straight down around the driver -- and visible, undisguised motors and crown gears are prohibited.
Entries that fail to comply with Appearance rules will be assessed penalties in accordance with the “Schedule of Penalties” (see below).
Chassis and Running Gear:
Chassis may be fabricated using any material or stock manufactured excluding carbon fiber. Both commercially available and scratchbuilt chassis are permitted.
Wheels, inserts and tires (see below for limits) should be in keeping with the period.
Tires:
Rears: 0.80" (20.32mm) minimum diameter, maximum width .2854" (7.25mm) at sidewall.
Fronts: 0.75" (19.05mm) minimum diameter, maximum width .2854" (7.25mm) at sidewall.
Min width .168 (4.25mm) at sidewall
Both front and rear tires must not have a contact patch of more than 7mm width where the tire meets the track at the start of the series.
Tires must be made from a rubber or urethane compound (no silicones or sponge rubber) and must be black or dark grey in color. No chemicals or oil may be applied to the tires. No clear paint or polish on front tires. Front tires must be soft enough to deflect under light thumbnail pressure.
Rear tires may not be slab sided tires like the old YellowDogs but may be one of the newer YellowDog rounded sidewall tires if they otherwise meet the height and width requirements. All rear tires must have an outer sidewall bulge like the real cars did in the era. The inner sidewall does not have to have the bulge but must be radiused (rounded) from the sidewall to the tread area.
The "spec"/only legal motor is the new BWA/DArt FF-050 motor with the label intact and visible. If the motor label is not visible from underneath the car, the body must be easily removable for Tech Inspection.
Gears may not be visible from above.
Minimum ground clearance is 1/16" (.0625", or 1.59 mm) except at gear, tires and guide.
Chassis wheelbase length measurement must be to scale with a permitted tolerance of 1.50mm. No car may have an overall width in excess of 50mm when measured between the widest part of the tires on either axle. A spreadsheet of scale wheelbase measurements is attached to the bottom of this post. Any dispute with the accuracy of these dimensions, must be posted publicly in this thread for review by all and a final ruling by the Race Director.
A single Guide is permitted and must not to be visible from directly above the car in the straight ahead position. No Slot It wood guide flags and all flags must be able to fit through a Scalextric R1 hairpin turn. (Guide measurement specs to come).
No traction magnets permitted.
Owners name should be written on the bottom of the chassis.
Entries that fail to comply with Chassis and Running Gear rules will be assessed penalties in accordance with the “Schedule of Penalties” (see below). Easily correctable infractions may be fixed by the Race Director, with the permission of the Entrant, and will be assessed a one-time penalty. Minor infractions not easily correctable may be raced, at the discretion of the Race Director, but will be assessed penalties on a per race basis. Cars with major infractions of the rules and technical problems that jeopardize the safe and efficient conduct of the event will be excluded and returned to the Entrant for repair.
CONCOURS D’ELEGANCE
This is a separate competition and will not affect the VRAA Race Results.
The VRAA Concours d’Elegance judging will be conducted as follows:
As all VRAA cars must be replicas of an actual car in an historic race, the following elements will be judged based principally on their accuracy and craftsmanship in replicating the original race car.
Twenty five points will be available for the construction, fit and finish of the body; including paint, decals, mirrors, roll bar, ignition box, windscreen, injector stacks, gear box, grill work and screens.
Ten points will be available for the driver detailing and cockpit details: including the dashboard, shifter, steering wheel and seat.
Ten points will be available for the suspension detail including; A arms, radius arms, tie rods, shocks, springs, sway bars, uprights and brakes.
The last five points will be given for how well the car looks going around the track.
Factory painted bodies will not be eligible for the Concours d'Elegance.
We encourage you to send photographic and other provenance of the historic F1 car upon which your model is based to aid the judge(s) in their decision.
SCHEDULE OF PENALTIES
After Tech Inspection, the Race Director will assess penalties for infractions of the Car Appearance Rules and the Chassis and Running Gear Rules as follows:
Car Appearance penalties are assessed once at start of season.
Car Livery – fantasy or grossly inauthentic (–10 points)
Car Cockpit – see-through to track (-5 points)
Wheel inserts - missing (-10 points) or not period correct (–5 points)
Suspension detail - minimum detail absent (–10 points per axle)
Driver – missing (-20 points) or period incorrect (-10 points)
Mirror(s), clear windscreen, roll bar, gearbox, engine, exhaust details missing where they should be present (-5 points per item)
Chassis and Running Gear penalties are assessed on a per race basis for as long as the car remains non-compliant.
Wheelbase measurement – outside permitted tolerance (-5 points)
Width measurement – between 50mm and 52mm (-5 points)
- over 52mm (exclusion)
Tires – diameter outside spec (-2 points)
- rear tire width or contact patch minor infraction (-5 points)
- other minor infractions (-2 points)
- rear tire width over 8mm (exclusion)
- material not approved (exclusion)
Ground Clearance - less than spec (-5 points), chassis contact danger (exclusion)
Guide or Gear visible from above (-2 points)
Guide – size infraction (-5 points)
RACE PROCEDURES, SCOREKEEPING AND CHAMPIONSHIP
Races will be conducted at between 10 volts and 12 volts at the discretion of the Race Host and according to the characteristics of the track. Race conditions, including driver and lane rotation, must be equal for all cars. Run order of cars and Race Heat organization is at the discretion of the Race Host.
Tires should be wiped clean before each Race Heat with a dry or damp cloth or finger. No chemicals should be applied to the tires.
A car with a minor technical problem (lost screw, loose wheel, gear, braid , etc.) may be repaired by the Race Host before, during or between Race Heats, though a Race Heat should not be halted or delayed while such a repair is made. No penalty will be assessed beyond racing laps lost during the repair.
Any major repairs will only be made between races at the discretion of the Race Host and with the permission of the Entrant. Otherwise, a broken car will be returned to the Entrant for repair at his expense. The Race Director must be advised of all major repairs or car returns. No penalty will be assessed beyond Championship Points lost due to missed races.
Finishing order for each round of the proxy race will be determined by total number of laps and 10ths of laps, within a set amount of time. A minimum of 12 (maximum of 15) minutes racing time per car is required at each track. The points won according to the finishing positions for each round from first place to twenty-fourth are:
50-44-40-36-34-32-30-28-26-24-22-20-18-16-14-12-10-9-8-7-6-5-4-3 with a fastest race lap bonus of 2 points.
At the conclusion of all the rounds, the total of all the points won, less any penalties assessed, shall determine the VRAA Champion for this season.

ENTRY INFO
Entry fee is US$25 per car to cover shipping costs between races, return of car to entrant and hopefully some prizes at the end of this event. Hey, postal rates aren’t going down! Shipping costs of entries from Entrant to Race Director at the beginning of the event are the responsibility of the entrant. If the car is crossing international borders, please declare the car as a “gift” and state a nominal value of $20 on the Customs Declaration. Funds will be tight enough on this series. I don’t want to pay taxes and duty on your entry!
I will provide a Paypal address for registration fee payments at a later date.
I will provide a ship-to address for entries at a later date.
All cars entered must be accompanied by a printed “CAR DATA FORM” that contains the following information:
Car Number
Entrant’s Forum ID and Actual Name
