Ohio Challenge Cup

Official Rulebook 2018-2019

Section 1 – General Rules

The Ohio Challenge Cup is a traveling series, founded with the goal of providing Flexi racers a venue for fair, cost-contained, and fun racing at a variety of raceways within Ohio and its neighboring states.

Series Function: The Ohio Challenge Cup exists to schedule races, maintain a concise rulebook, promote Stamped Steel or “Flexi” racing, and present awards to recognize the accomplishments of its racers

Board of Directors: To ensure the effectiveness of the OCC, three Board of Directors positions must be filled.

Series Director: The Series Director is the series ultimate arbiter, acting as liaison to both Track Owners and Manufacturers, arranging the series schedule and acting to resolve race day conflicts in breach of the series Code of Conduct. The Series Director also acts as the series' traveling race director to ensure consistency from race to race. 2018-19 Series Director, Justin Porter

Technical Director: The Technical Director is the series technical adviser, responsible for checking all cars at Tech to ensure consistency in all races. The Technical Director also reviews all submitted components for future approval. 2018-19 Technical Director, Eric Shirey

Treasurer: The Series Treasurer collects all entry fees upon race day, ensuring both Track Owner and Series receive their accurate amounts as well as negotiates purchases for the Ohio Challenge Cup including but not limited to plaques, trophies, and the equipment for the Season Finale Enduro. 2018-19 Treasurer, Ron Vincek

Race Day Procedure: The Ohio Challenge Cup sanctions races at participating tracks with the intent of offering its competitors a fair and consistent program. To this end, these procedures are to be followed at each event on the calendar.

Practice: The day will open with open practice from doors-open at 8:00am until the announced “Tech” time. Except in unusual circumstances, this should be no later than 10:00am.

Entry Fees: An entry fee of $7 per class will be collected at the time of tech by the Treasurer, as well as a $5 Practice and $5 Lunch fee. $2 of each entry fee is kept by the Ohio Challenge Cup for administrative use with the remainder belonging to the participating raceway.

Tech: The Tech process will be performed by the Technical Director for ALL divisions at the close of practice using the Ohio Challenge Cup designated Tech Tools. In the event of a dispute, the Series Director will review the measurement with a second copy of the same tool.

Tech Sheets: Tech sheets will be supplied by the Treasurer for all three divisions with corresponding information for each division's car. It is expected that they be filled out to the best of the racer's ability for promotional and rule-making purposes. Sheets with required fields (Name, Home Raceway, Body, Chassis, Gearing) not completed will be considered a tech failure and car and sheet will be returned to the participating racer to be completed. ADDENDUM: Home Raceway MUST be an active commercial or club raceway.

Order of Events: The Race Day will begin when the last car is passed through tech, at which point the first group of GT1-B racers will be grouped. The racing will then proceed as follows with the lowest seeded main starting first.

- Racers Meeting

- GT1 B

- GT1 A

- Lunch/Group 10 and GTP Qualifying

- Group 10


Division of Racers: In the interest of fair and clean racing, in the event of a field of 12 racers or fewer in a division the race format will be a Round Robin. In the event of 13 or more racers, the race format will be Split Mains who will be scored collectively.

Division of Mains: In the interest of keeping the racing day as brief as possible, every effort will be made to group mains into full fields of 8 to 11 racers. As such, when running two or more mains the series will default to ROUND ROBIN format races whenever possible to prevent overlong race days.

Qualifying: In an effort to create more balanced racing and to bring the Ohio Challenge Cup in line with other touring series, Group 10 and GTP will qualify to set their groups.

Qualifying Time: Each racer's qualifying attempt will be 60 seconds, from which their fastest lap will be counted.

Qualifying Order: Order of qualifying will be set by order of tech.

Qualifying Marshals: Qualifying will be marshaled by ALL PARTICPATING racers. Failure to Marshal will result in suspension of lap time and placement in the lowest seeded qualifying position.

Lane Choice: After mains are set, lane choice will start with the highest seeded racer in that main and continue from there until all racers have their lane placed. GT1 lane assignments will remain At Random in both A and B. GT1 Main assignment will be set according to season points.

Race Format: Ohio Challenge Cup races are structured to allow for tight but friendly racing on a variety of tracks with an emphasis on fun and a brief as possible racing day.

Race Length: Ohio Challenge Cup races will consist of eight (8) heats with each heat being two (2) minutes in length

Starting Line: Cars will be distributed to their racers by the Series Director to be taken to the Raceway designated starting line, where they will be lined up with their front bumpers on the line.

End of Race: When power goes off at the end of the final heat, the Series Director or Treasurer will collect the cars from the track in the order requested by the Technical Director who will note finishing panel number. The recording Board member will remove lane stickers and INITIAL THEM with DIVISION and RACER's INITIALS to use as finishing markers in the event of a tie at panels.

Impound: All cars are impounded at tech until the conclusion of their division's races.

Podium Cars: The Top Three cars in a given division may be subject to a post race tech at the discretion of the Technical Director in co-ordination with the Raceway Owner. The Top Three cars and racers will also be photographed for promotional and celebratory purposes.

Points: Points shall be awarded per the overall results in each division using the following table.
- 1st place: 180 points
- 2nd place: 170 points
- 3rd place: 165 points
- 4th place: 160 points
- 5th place: 155 points
- 6th place: 150 points
- 7th place: 146 points
- 8th place: 142 points
- 9th place: 138 points
-10th place: 134 points
-11th place: 130 points
- 12th place until lowest finishing position awarded in descending 3 point intervals.

Attendance Bonus: Any Racer attending all eight (8) races of the 2017-18 season will be awarded an additional ten (10) bonus points per division.

Points Drops: All racers will have their two lowest points scores dropped at the end of the season. Absences will count towards drops.

Points Ties: In the event of a tie, the tiebreaker will first be number of wins. If neither tied racer has wins, it will go to their highest finish.

Racer Conduct: To ensure a fair and friendly atmosphere for all participants, racers should consider themselves not only competitors but also ambassadors for their home tracks and the sport as a whole. To this end, the series asks and enforces a racer Code of Conduct.

Marshaling: All racers are expected to marshal the divisions in which they participate. At the beginning of each race, the Series Director will announce marshaling assignments which must be filled.

Track Calls: Track Calls are to be made by Turn Marshals or the Competition Director for the following situations.
- Car out of reach
- Car on floor
- Damaged Car which is To Be Returned to Its Racer at which point the race will continue

Rider: Racers, Marshals, and the Technical Director are all at their discretion to announce a Rider.

Missed Laps: A car that has traveled past the lap counter without counting will have its lap added through the lap counting software without losing distance covered in the event of the off. In the event of a recurring lost lap, a track call will be called to determine if track or racer's car is at fault. In the case of the track being at fault, repairs will be made. In the case of a racer's car being at fault, the race will continue while the racer makes needed repairs.

Track Software Failure: In the event of a software failure during a Main, the Main will be re-started at Heat One. Raceways are expected to have all Software and Wiring in functioning order. Recurring issues (more than one software failure in one main) will result in a drop being issued for the affected race.

Verbal Conduct: The Ohio Challenge Cup will not tolerate abusive or profane language directed at fellow competitors, turn marshals, raceways, or the series officials.

Unsportsmanlike Conduct: On track conduct should reflect fair and respectful behavior. Knowingly driving with the intent to damage track or fellow racer's property will not be tolerated.

Violations: In the event of a Code of Conduct Violation, a Series Official has five grades of penalty to be levied upon the participant in question.
1St – Verbal Warning

2nd – Ten Lap Penalty
3rd – Dismissal from Race without Points or Refund
4th – Dismissal from Event without Points or Refund
5th – Dismissal from the Ohio Challenge Cup

By Entering an Ohio Challenge Cup Event, all participants agree to this Code of Conduct.


These are the complete official Ohio Challenge Cup OCC Rules that apply to all OCC Classes. In the case of a discrepancy between these General Rules and an individual Class Spec Sheet, or any other information, the General Rules apply over all class specific rules. In the event of a contradiction of rules, notify the OCC Director, presently Justin Porter and/or the OCC Technical Director, presently Eric Shirey for an immediate ruling. It will then be clarified prior to the next scheduled event.

Objective of the Series Rulebook: To Maintain a set of rules for all Racers to follow which is equal for all racers, as well as provide a viable racing platform for manufacturers and raceways alike, focused on Cost-Containment, Fairness, and Stability.

Technical Director Ruling: Technical Director's ruling on any matter applies over these or any other Rules. The Technical Director may allow, at his sole discretion, a grace period of ONE event after notifying the Member of the needed change.

Cars which have had major components replaced during the course of the race (motor, guide, tires) will be subject to post-race tech at the discretion of the Techinical Director.


OCC GT-1 (A for Professional, B for Amateur )

- Purpose: OCC GT-1 is a Class designed to contain the costs and performance of flexi-type slot cars, offering a class with close competition and tightly controlled tuning options

– GT1 Division Separation: GT1 racers are to be separated into a GT1 A and GT1 B group, to be raced, scored, and awarded season points separately.

- GT1 B is to be comprised of novice and/or casual racers, grouped based upon prior performance, amount of experience, and where data is lacking, at the recommendation of their Home Track Owner.

- GT1 A is to be comprised of veteran racers and/or racers of note within the hobby, grouped based upon prior performance within the Ohio Challenge Cup, notable performance within the past 3 years in National or Regional championships, Premier Events, and where data is lacking, the recommendation of their Home Track Owner

- Within the Ohio Challenge Cup, there are three methods that ensure a move-up from GT1 B to GT1 A, those being to win the GT1 B championship, to win an OCC Group 10 event, and to win an OCC GTP event. The move from GT1 B to GT1 A will occur at the first event of the following season.

3.0 Controllers
