finals depending on the number of entries.B. All races designated as “consis” will be contested over 4 lanes only, running

on either the red set i.e. red, green, blue, purple or the black set i.e. black,yellow, orange, white.

C. All other races will be contested over 8 lanes.D. All races will be on a “move up” basis. The following schedule has been

adopted to ensure that a minimum of four drivers will move up from eachrace.

1 to 8 entries: Final only9 to 11 entries: Round Robin12 to 22 entries: two round-robin semis and final. Top 4 in each semi

move up.23 entries: one round-robin heat, two semis and final. Fastest 12

qualifiers into semis - top 4 in heat move up.24 to 44 entries: Four quarterfinals, two semis and final. All entrants

start in quarterfinals, top 4 in each move up to semis, topfour in each move up to final

45 to 46 entries: Two round-robin consis, four quarterfinals, two semis,and final. Fastest 24 qualifiers into quarterfinals, top 4 ineach consi move up.

> 76 entries: For races with over 76 entries create sub-sub-consis (andsub-sub-sub-consis if needed) using the same procedures asfor sub-consis. Top four in each race always move up.

E. Lane choice will be determined first by qualifying position then by laptotal and position from previous heat.

F. In moving racers up from Consis, Quarterfinals, or Semis, the same logicapplies. Lane choice selection order is determined by the total lapsturned by the winners of the qualifying race1. For main event move-ups first pick goes to the racer with the most laps

out of the two semis, second pick goes to the racer with the most lapsout of the other semi.

2. Choices are then alternated between semis. Third pick goes to the secondplace finisher in the semi that had first pick, and fourth goes to thesecond place finisher in the semi with second pick etc.

they stopped. Putting a car back on the track in an advantageousposition, will result in a rive lap penalty. A second infraction willresult in disqualification. It is the drivers responsibility to know wherethe car stopped. When a car is removed from the track during racing,the same rule applies. Corner marshals should notice the cars stoppingin their section and pay close attention to cars near the lap countersection. At the conclusion of each race, cars will be left on the trackuntil the order of finish is positively determined.

2. Lane change cards are required to be used for the NationalChampionships

F. UNSPORTSMANLIKE CONDUCT1. Unsportsmanlike conduct on the part of a driver or turn marshal will be

subject to immediate disqualification at the discretion of the racedirector. Verbal abuse or profanity will not be tolerated. The racedirector may first warn drivers, marshals or pit helpers if their behavioris unacceptable. Serious or repeat violations will result in a five lappenalty for the first infraction and disqualification for the second.

2. Repeat offenders of any of the unsportsmanlike conduct guidelines maybe prohibited from future USRA events.

G. PROTESTA competitor may protest another racers equipment by officially informing

the race director. Special provisions for armature protest are in thefollowing section.

1. A racer must be aware of the rules when entering and withdrawal is notan option in the case of a protest

2. Any racer in a USRA sanctioned race whose motor is protested and thenrefuses to have his/her motor torn down shall be banned fromcompetition in any USRA race for a time of one year from the dateof said infraction

ARMATURE PROTEST (RESTRICTED CLASSES ONLY)1. Any competitor may protest another person’s armature. He/she must

officially inform the race director, at which time the race will bestopped.

a. The protester may buy a look by posting a $2.00 fee. He/ she is thenentitled to look at the suspected armature in the car.

b. If not satisfied, he/she may formally protest which requires posting afee equal to double the current manufacturer suggested retail priceof their respective armature. The buy a look fee is transferable.

d. At this time, the armature must then be non-destructively andindelibly marked (suggest unique Dremel marks on the shaft).Extreme care must be exercised to avoid damage to armaturebalance and delicate components such as ball bearings, motorbrushes, etc.

20

c. An impartial race steward must then be charged with theresponsibility of observing and verifying the authenticity of thearmature for post race inspection. The race will then be restarted.

2. Thorough disassembly and inspection must be conducted immediatelyupon completion of racing, and must be conducted in a mannerassuring accurate technical verification. Armature stack length willbe measured, and if within specs the inspection will proceed to thewire. This can be accomplished by destroying any epoxy or similarbinder with extreme heat (a common torch does this nicely), Thendissecting the armature with a Dremel and carefully measuring thewire and counting the turns.

3. The fees will be held by the race director until resolution of the matter,then promptly surrendered to the appropriate party. Likewise, anywinnings and/or points will be held pending the outcome of theinspection.

4. Buy a look proceeds go to the protested party if not applied to aFORMAL PROTEST.

5. There is a maximum limit of $100.00 for protesting Group 27 armatures.XII) HOSTING A NATIONAL EVENT

Any raceway or persons involved in slot car racing may make a bid to host aNational Event. Following is a list of guidelines which may be helpfulin preparing presentations.

A. The raceway or promoter should be well established with a reputation fororganizing and directing a well run race. The more racers that haveattended one of your races, the better. That would allow the USRAdirectors more input on how well organized your business is.

B. If you plan to bid for the USRA Nationals, you must notify the USRADirector of your intentions to do so. This must be accomplished inwriting no later than ninety (90) days prior the current year’s Nationals

C. The bids for the next Nationals are presented at the General Meeting at thecurrent year’s Nationals. Your presentation should include:

1. Pictures of your raceway or host site, and of previous races (ifpossible).

2. A summary of some of your previous races, including your raceschedule, number of entries, etc.

3. Details about your track and your lap counter system, includeinformation about track power, batteries, color, braid recess, powerpolarity, etc.

4. Information concerning lodging, airlines, restaurants, and places ofinterest.

5. Pictures of pit space.6. Letters of approval from your City Directors, radio or television stations.7. A mock race schedule of dates, times, and activities for each day of the

National Event. This is a requirement that must be included in any bid.

21

8. Your presentation should be placed in book form (such as a photoalbum), so that it can be passed around for all interested parties toview. Two or more copies of your presentation would beadvantageous.

9. Talk to previous National Hosts.10. Each bid for the National Event will include financial details of the race

to include: Guaranteed purse, entry fees, warm up race entry fees, pay-outs, cost of track time.

D. Each bid for the USRA Nationals will be accompanied by a refundabledeposit of $500.00 (cashiers check or money order). The deposits willbe returned promptly after the site selection voting to the unsuccessfulbidders. The deposit for the successful bid will be returned after theNational Event (two weeks) provided there are no financial problemssuch as bad checks, failure to deliver advertised pay-outs, etc. Iffinancial problems occur, the deposit will be forfeited and the USRAtreasurer shall use it fully to correct bad checks or other losses in anequitable way. The dispersal of funds is to be included in theTreasurers report.

E. All entry forms and/or tech sheets are and will remain the property of theUSRA. All of these forms must and will be turned over to USRAofficials only.
