  • 2009 NINCO Regional/National Race Rules

    It's that time of the year again....the MRC / NINCO Regional/National race rules.

    Although the 4th qtr date and location of the World's most prestigious International slot car race, the NINCO World Cup Super GT has not been set, we will (as in previous years) run a series of regional races throughout the USA, governed by NINCO World Cup rules, prior to the World Cup race.
    The National and Regional Race Locations and race dates will be published as soon as the information is known.
    The following are the rules that will be used in the USA for the races:
    __________________________________________________ __________________________


    1. All competitors (racers) entering these races agree to abide by these rules.

    2. The rules are designed to enhance competition, provide an “even playing field”, and most important, create an atmosphere of fun, excitement and enjoyment for both racers & spectators.

    3. The US National race open to all citizens and permanent residents of the USA, 18 years and older and Canadians.

    4. 1st, 2nd, and 3rd place winners of the NINCO regional races will be guaranteed a racing slot if they choose to attend the National race. This does not include transportation, accommodation, the entry fee or any other cost of attending the National race. They will be required to pre-register and send a deposit.

    5. Regional race 1st, 2nd, and 3rd place winners will not be allowed to race in other regional events.

    6. A moderate entry fee will be charged at each race location, determined by the local race organizer.

    7. Endurance race lengths and lane positions will be determined by the local race organizer.

    8. At the time of this writing, the following NINCO cars are the only packaged cars that will be allowed to race in this race series: 50516 Lexus SC-430 "Team Tom'S"; 50522 Ferrari 360 "Piedrafita Lightning”; 50528 Ferrari 360 “Chefo Sport Lightning”; 50513 Lamborghini Gallardo "Triple A": 50523 Lamborghini Gallardo ASP”; 50531 Lamborghini Gallardo “Blancpain”; 50501 Mosler MT900R “Lightning Evo”; 50500 Mosler MT900R “Lejun”; 50545 Mosler MT900R “Nextel Lightened”; 50526 Porsche 997 “Veltins”; 50496 Porsche 997 “Innovate”; 50530 Porsche 997 “Insviar”; 50532 Ford GT GT3 “Matach Adac”; 50549 Ford GT GT3 “Matach Dubai”; 50505 Acura “Patron”; 50515 Acura “Lowe’s”;, 50525 Acura “XM Lightning”; 50517 Lotus Exige “Zagame*”; 50518 Lotus Exige “Quintessence*”; 50534 Lotus Exige “PB Racing Rally*”. Other specific models may be added at a later date.

    9. Completed cars constructed using NINCO Lexan chassis’, and Lightweight Body Kits can be used, providing all the general rules are followed.

    10. All cars must race with no magnets; must have the NINCO NC-6 “Crusher” motor and NINCO Shore A25 or NINCO Laprene rear tires. *Lotus Exige cars must race with the standard NINCO NC-9 motor*.

    11. Each racer will purchase (from the Race organizer at each location) an NC-6 motor or NC-9 motor for the Lotus Exige, and NINCO Shore A25 or NINCO Laprene rear tires. Motor & tires will be randomly “picked” by the racer to insure fair/equal selection and “as issued” by NINCO.

    12. At the discretion of the race organizer, the cost to purchase the motor and tires can be combined in the entry fee or charged separately.

    13. Cars can be raced stock or modified. Only NINCO parts made for that series car can be used on that car. The exception being braids, wires & body mount screws can be used from other manufacturers. NINCO Stock, Prorace or Prorace Evo parts can be used. The use of the “green” 22mh choke (used for electrical noise suppression) on the motor terminal is optional.

    14. Racers can bring their own cars (see rule 8) & NINCO components, or purchase cars & components trackside

    15. All participating racecars will be inspected to insure rule compliance prior to the start of the race. A few (determined by the race organizer) test laps will be allowed prior to final inspection.

    16. Competitor’s cars will be impounded by the race organizer after inspection. At race time, the track marshals will set the cars in their appropriate lanes. Except for maintenance during “green” periods, the racer will not have access to his car until his racing is complete. (see rule 17) The race organizer is free to check any participating car during the race (between rounds) and at its conclusion to ensure rule compliance.

    17. Cleaning braids in between rounds can be done if observed by a track official. Except for re-gluing the rear wing (see rule 19), No other adjustments can be made at this time.

    18. Painting the outside (and only the outside) of the car body is allowed. Windows must not be painted. Decals can be applied to Body Kit shells.

    19. The body (whether a named model from Rule 8 (above) or a NINCO “white” Body Kit, must be the completed car body as manufactured by NINCO: no lightening, strengthening, modifying, trimming or adding weight. The rear wing, mirrors, grills, windows, windshield wipers and all interior parts (cockpit, driver, floor pan, etc) must be in place as issued by NINCO. The rear wing must be clean and can be glued to the body. The wing angle cannot be changed as a means of attempting to affect the down-force applied to the car. If the wing breaks during the race, it must be replaced by gluing, or it can be fixed to the body using adhesive tape so long as it does not damage vehicle aesthetics or cause a change in the angle and the amount of down-force the wing provides.

    20. The chassis must be strictly the chassis for that car series.

    21. No modification to any part of the chassis is allowed. However, you may replace chassis screws that hold the body to the chassis with NINCO Prorace/Evo or any other type found within the slot car market so they may be loosened/adjusted to allow the body to rock/float over the chassis. Weight cannot be added to the chassis

    22. NINCO’s Lexan chassis’ can be used with any applicable listed cars (in Rule 8).

    23. For a standard chassis, the motor cannot be "glued" in a manner that adds strength, weight or minimizes flex of the chassis... (i.e. running a bead of hot glue down the entire sides of the motor that effectively make the motor a part of the chassis). A minimal application (single piece) of tape may be used to secure the motor.

    24. If the Lexan chassis is used, the motor must be secured with the motor mount screw provided with the chassis. In addition, a (minimal size) single piece of tape can be applied.

    25. All body parts, wings, mirrors, interior parts, windows etc., must be in place at the race start.

    26. Tires may be sanded/profiled, but must be recognizable as original NINCO tires.

    27. No chemicals of any kind can be used on the tires. (Tires can be “rolled” over masking tape for a final cleaning prior to the car being impounded for the race).

    28. Tires can be glued to the hubs (wheels)

    29. Prorace/Evo wheels may include hubcaps & discs

    30. The assembled front NINCO axle length may be altered by shortening to reduce side-to side play. “Shims” to reduce spacing cannot be used. In no case can the front axle assembled with wheels & tires hang more than 1mm over each side of the body.

    31. The assembled rear NINCO axle with wheels & tires must not hang more than 1mm over the side of the body, except to allow for minimum “play” to enable the axle to turn freely without the inside of the hub
    rubbing against the chassis. (Race organizer will determine the 1mm requirement for rules 30 & 31)

    32. Stock, Prorace or Prorace Evo hubs (wheels) of standard NINCO 2.48mm axle size, or NINCO 3/32” axle size of 15”, 17”, or 18” narrow or wide, and any size NINCO Shore A25 (except F-1) or NINCO Laprene tires can be used on any (rule 8) car, providing wheel/tire sizes are not mixed on each axle and both axles are the same diameter front and rear. 15" hubs (wheels) cannot be used on the rear axle.

    33. Wires & braids can be used from any 1/32-scale slot car manufacturer.

    34. Slot Guide Flag must be the type (part) from that car series, or the associated Prorace guide. The fork may be lowered a maximum of 1mm at the bottom and it’s thickness may be (profiled) reduced, to prevent it getting stuck inside the slot. Total or partial suppression or stretching of the active guide spring is allowed.

    35. Bushings that are original equipment or the appropriate NINCO Prorace/Evo bushings or ball bearings can be used on the rear axle. A minimal amount of glue (that does not strengthen the chassis/axle supports) may be used to fasten the bushings/bearings in place if desired.

    36. Pinions and Crown (Spur)Gears - Free choice of NINCO gears, (stock, Prorace, Prorace EVO) may be used, but must be in line with NINCO’s specifications. In no case may a pinion be used where the crown gear requires modification. The crown gear cannot be modified in any way that will change the “natural wear” of the gear.

    37. Once the race starts, a competitor can only “pit” his car, during actual racing or "green" periods. “Pit” means: cleaning braids, changing tires (rear NINCO Shore A25 or NINCO Laprene tires must be obtained from the race organizer), replacing a wheel or tire that came off the car, or putting the car back to running order after a crash that immobilizes the car. Track marshals will get the car for the racer and replace the car on the track at the location where the car was removed. The rear wing can be repaired and replaced during “red” or “green” periods. The racer will lose time and laps taken during these maintenance (Pit) periods.

    38. Gear and tire size changes during “green periods” are not allowed.

    39. Any recognized 1/32 hand control (electric or electronic) on the market may be used so long as it does not include circuitry that boosts the power delivery to the car. Race management is free to check the controllers at any time during the race. It will be the responsibility of the individual racer to check and insure he has the correct polarity connections / alligator clips to interface his controller with the racetrack.

    40. Any vehicle modification or manipulation of vehicle parts in an attempt to circumvent the spirit of the rules set out in the present regulation is totally prohibited. If discovered by track officials, the vehicle and racer will be disqualified from the Regional race, and from entering or racing in the National race.

    41. The voltage on all lanes of the racetrack must be between 12-15 VDC

    42. Track Marshals - Participating drivers if asked, must carry out “Track Marshalling” functions. Track Marshals are required to place cars back in their appropriate lane after an accident, and remove objects from the track that might interfere with normal racing. The Marshal is required to warn drivers as appropriate about accidents in his sector of the track. Cars that deslot/involved in an accident shall then be removed by the Marshals as quickly as possible so they don’t obstruct the other drivers. Marshals shall attempt to replace cars in their proper lane with the vehicle that caused the accident being the last one replaced. Vehicles that have had an accident shall be replaced on the first straight run following the accident site, a minimum distance of approximately 1 foot from the last curve.

    43. The race organizer at each regional location will make the final decision concerning any rule infraction or discussion at his location during race day.
