  • 2017 Thunder Slot Lola N. America Championship

    Thunderslot has authorized Great Traditions (aka GTSLOTS) to run a North America race program for their Lola T70 MK III car models. Regional races will be scheduled, culminating in a North America Final race to be held on November 5, 2017. The Finals will take place at Great Traditions, 831 Byberry Road, Philadelphia, PA. Track opens 8 am, tech inspection starts at 10 am, racing scheduled to start about 1 pm.

    To qualify for the finals, you must finish in the top 4 of one of the 2017 Thunderslot Lola regional races to be announced soon, or have a prior champion's exemption as a previous winner of a GTSLOTS championship final within the past 5 years.

    Any shops, clubs or slot car organizations interested in holding a regional event contact Robert Holt by phone (908-397-7886) or e-mail ([email protected])

    Below is a picture of the Great Traditions track used for the N. America Finals:


    ELIGIBLE CARS:
    Only the Thunderslot Lola T70 Mk.3 GT (Coupe) and Mk.3 (Spyder) cars as raced from 1967 thru 1973 in endurance racing, the USRRC, the Can-Am, and the Interseries are permitted. See the attached cars/parts list for the approved car releases, kits, and parts. Kits must be complete with all parts that are supplied with the kit, excepting those changes permitted below. As they are introduced, newly released cars will be reviewed and added to the approved list if eligible. See pictures below for eligible car examples:



    GENERAL:
    Any modifications or parts not specifically addressed in the series rules or are not listed in the approved cars/parts list are not legal and will not be permitted. If the rules stated on this page do not indicate a part or tuning method IS allowed, it is NOT allowed. Any modifications that are made and/or tuning techniques used are made at the racer’s own risk. Any variations to these rules must be approved in advance by GTSLOTS. All rules are subject to change.

    THE BODY:

    Bodies may not be modified, lightened, or cut in any way - including wheel wells, body posts, interiors, etc.

    EXCEPTIONS: Sharp edges, burrs, and mold flashing may be trimmed and/or sanded to permit clearance for the proper seating of the body onto the chassis and to allow for body float. No more than .010” of material should be removed where applicable. If a standard credit card can be passed in the gap between the body and chassis, the sanding has exceeded tolerance and the car may fail inspection. All cars including kits must start each race with any and all front and rear spoilers/wings, headlights and/or headlight covers, air scoops, engine intake details, rear body spare tire/exhaust details, miscellaneous body details, and wheel inserts in place as provided with the car. Mirrors, small aerodynamic front trim tabs (winglets), and wheel insert spinners may be missing, but should be replaced when possible. (Note: Coupe and Spyder wheel inserts are interchangeable.) Bodies and interiors may be custom painted, but all cars must have proper numbers and markings as is prototypical and look like race cars of the era represented. Bodies must be attached by any and all screws locations provided by the factory using only Thunderslot screws and the use of Thunderslot M2.5x3mm hexagonal (set) screws to control body float are permitted at the 4 locations provided in the chassis. Shims are permitted to adjust chassis/body/spur gear/tire tweak and clearance. If body screws are run loose, tape should be placed over the screw holes on the bottom of the chassis where possible. All cars must use the complete and unmodified interior w/driver figure as supplied with the car. All windows must remain transparent as is prototypical.

    CHASSIS/PODS:
    Only Thunderslot chassis and sidewinder pods may be used and may not be modified in any manner. NO TRACTION MAGNETS. Thunderslot standard, spring, or sponge ring type suspensions are permitted using only Thunderslot supplied parts utilizing a minimum of 3 mounting points (1 front point & 2 side and/or rear mounting points). Spacers between motor pod and chassis screw locations to adjust chassis tweak are permitted. Sanding of the edges and interference points of the motor pod and the chassis for fit and float is legal. No more than .010” of material should be removed where applicable. If a standard credit card can be passed in the gap between the chassis pod, the sanding has exceeded tolerance and the car may fail inspection. Mold flashing and the plastic injection/molding ejection/overflow expansion points may be removed (Note: this does not include wire pathway posts). Front axle ride height adjusting set screws utilizing Thunderslot M2.5x3mm hexagonal (set) screws (upper and lower) may be used and adjusted as required. NO other modifications to axle mounts front or rear are permitted.

    AXLES\BUSHINGS\WHEELS\TIRES:
    Only Thunderslot axles and bushings are permitted. Bushings may be glued in place. Only Thunderslot 14x9mm nylon front wheels and 14.3x10mm aluminum rear wheels are permitted utilizing any Thunderslot Lola T70 inserts. Wheel insert assemblies (inserts with or without spinners) may be painted, and all cars must start each race with all wheel inserts in place. Any manufacture’s axle shims and spacers are permitted. All rear tires are to be supplied by race host (Regional) or GTSLOTS (Regional and National) on race day unless otherwise noted.

    Approved tires are:
    “Quick Slicks” tire(s) #TS43XF (.785”x.390”) or #TS44XF (.803”x.390”). Thunderslot front tires only can be used on the front and may be both glued and trued. Front and rear tires may not extend past the body at any point. No chemicals may be used on the tires. Tires are subject to change at the Nationals and due to availability some tire sizes may not be available. Regional hosts can determine tires to be used for their regional race.

    GEARING:
    Only the Thunderslot 11 tooth 7mm (plastic or brass) pinion and 32 tooth 17mm (ratio – 2.91) plastic sidewinder spur gear are to be used. Driver may apply grease to the gears.

    GUIDE BLADES/BRAID/ELECTRICAL:
    Only the Thunderslot guide blade is allowed and shimming is permitted. The leading edge of the blade may be sanded to profile and to remove sharp points and edges. (Note: it has been found that the angled forward bottom tip of the guide blade has an interference issue on Scalextric track due to hitting the pickup rail support tabs used to hold the rails in place. It is recommended for racing on Scalextric track that the leading edge of the blade should be profiled straight up and down.) Any manufacture’s braid and wire can be used; must be attached to the guide/braid through the use of any manufacture’s eyelets, or bare (or tinned) wire; and held in place using the M2.5mm set screws system built in to the guide blade. (Note: the lead wires may be crimped or soldered directly to the eyelets only and may not be glued or soldered to the braid.) Only the Thunderslot guide blade is allowed and shimming is permitted. Any manufacture braid and wire can be used, must be attached to the guide/braid through the use of Thunderslot eyelets and the M2.5mm set screws built in to the guide blade, and may not be glued or soldered.

    CAR SPECIFIC ALLOWED MODIFICATIONS:
    In order to foster competition and create parity between the different models of the Thunderslot “Lola T70” cars, the following approved modifications are being permitted on a car by car basis (Note: all modifications should be made in a clean and professional manner and not deter from the proper “look” of the car). Any such modifications are made at the racer’s own risk:
    General (all cars):
    - Note: If the Thunderslot Mach21 Double Shaft motor is used, the motor will require approximately 3/32” (.093”) of the motor shaft on the can end of the motor
    removed to clear the gear side rear tire. The endbell side shaft may also be trimmed, however is not required as there is no interference with any part of the
    car.


    Lola T70 Mk.3 GT (Coupe): none required at this time

    Lola T70 Mk.3 (Spyder):
    - Note: Caution is required with the clearance under the front end of the body (chin & chin spoiler) so as to prevent interference with the track surface. Spacers
    between the chassis and the front body posts and/or additional attention to the adjustment of the front body screws and the other available adjustment points on
    the chassis is permitted.



    MOTOR:
    Regional Events:
    Motors to be provided by the race host or racers themselves (Thunderslot 21.5K motor – rated 21.5k rpm @12volts) using Thunderslot 11 tooth 7mm plastic or brass pinions only. It is suggested that the motors of the top 5 finishers be tested at the conclusion of the event to confirm legality with the results (if tested) provided to GTSLOTS along with the event race results. (NOTE: Contact GTSLOT technical contacts shown below for additional information on the testing of motors.)
    Nationals:
    Only the provided handout (Thunderslot 21.5K motor – rated 21.5k rpm @12volts) motor is legal for the National event and will be supplied by GTSLOTS. Motors will be pre-tested, will be supplied with the shafts pre-trimmed to properly fit in all cars, will be pre-lubricated, will be marked with an ID code, racers will provide their own pinion gears (Thunderslot 11 tooth 7mm plastic or brass), and must be used as supplied without further modification. (Note: if the Thunderslot Mach21 Double Shaft motor is supplied, Racers will be required to remove approximately 3/32” (.093”) of the motor shaft on the can end of the motor to clear the gear side rear tire. The endbell side shaft may also be trimmed, however is not required as there is no interference with any part of the car.) Racers/Tech Inspectors will be responsible for the soldering of the lead wires to the motor tabs without overheating the tabs and causing damage to the motor. No chemicals (example: Voo Doo drops, etc.) shall be added to the motors. For the sole purpose to hold the motor in place, motors may ONLY be attached in place in the motor support using Thunderslot motor screws through the appropriate screw holes provided in the motor support and into the pre-threaded holes in the “can” end of the motor. Racers would receive their handout motor at a predetermined time at the event, have the opportunity to test/practice with the handout motor before the start of competition, the option to purchase a replacement motor prior to the start of competition, and keep the motor(s) at the conclusion of the event.

    WEIGHT:
    Weight may be added to the inside of the chassis. NO weight may be attached to the underside of the chassis.

    LIGHTING (Optional):
    Not permitted.

    TRACK VOLTAGE:
    Suggested 12 volts (Note: track power will be set at 12 volts for the N. America finals and the GTSLOTS regional races)

    RACE PROCEDURES: (as to be used at the N. America finals and GTSLOTS regional events):
    - All participating race cars will be inspected to ensure rule compliance. A few test laps (the number to be determined by the race organizer) will be allowed prior to the final inspection.
    - It is the responsibility of each participant to make sure that the front spoiler, chassis, and spur gear of their car has sufficient clearance to the track and pickup rail surface so as not to rub under race conditions and will be inspected for such clearance.
    - Loose parts, wheel inserts, etc. may be attached and/or repaired using any type of available glue.
    - Cars will be impounded after the inspection process and drivers cannot touch their cars unless done under “green flag” race conditions under the observation of a race official.
    - Any controller is permitted, provided that the controller does not store an electrical charge.
    - The race director for the event (the race organizer holding the event) will have the final determination if any questions or conflicts arise.
    - Drivers and/or their authorized representatives may repair broken or damaged cars (IE: damaged braids, broken wires, loose gears and/or wheels, lose or missing screws, etc.) during “green flag” conditions, only under the view of a race official assigned by the race director, repairs must be properly performed to meet all posted rules, and parts may not be torn or broken off the car where screws are used to retain the parts (IE: the front spoiler, etc.) to perform the repair.

      Per the rules, no. The Thunderslot bushings are designed to fit the Thunderslot pods with proper alignment, where with other types of cars where other manufactures parts were used, the bushings permitted did not always fit properly and required gluing in place to maintain proper alignment.

        Yes the bushings do fit but, depending on how much slop you like the bushings will move in the motor pod and may not be aligned.

          Your allowed to glue the bushing in every other
          race you can even glue the ones in the slot.it pods which
          are made to fit. These are mass produced chassis that are not
          identical in form, fit and function. So now we can't glue them and you
          will have some buy 15 pods to find the one that is going to give him and advantage.
          If I was running a Sideways group 5 with the stock pod I'm allowed to glue the bushings so why can't
          we do it with this class. It doesn't make sense.

            These rules are written in the building style of only one car builder. There is no room for a racer to build the car to suit their style.

              As this is the first time this brand of car is being used in this form of competition, the rules currently presented were based on certain principals. We knew that there would be required modifications based on issues discovered while testing and possible equalizers required between the "coupe" and "spyder" versions of the car that are yet to be even tested. The gluing of the bushings in place is currently being considered along with several other items that are yet to be tested. You are certainly free to try and test anything that you would like and suggest modifications to the rules, however realize that your car as entered in the regional and final events must meet the rules as posted.

              By the way, the gluing of the bushings in place on the Sideways Group 5 series cars was not specifically permitted per the rules. Do not consider something permitted if it is not specifically addressed in the posted rules.

                  Bob,
                  There is a very key difference between the recently run races and the Thunderslot. Each of the recent prior used bushings that were either press fit into a pod (Slot It in a Sideways race) that prevent cross car movement or bushings with a flange on both sides in a press fit cradle that also limited cross car movement.

                  The Thunderslot bushings are held in by cross car compression via spur gear, axle spacers or wheels. As previously mentioned a racer choosing to run with rear axle spacing that allows cross car axle play may result in bushings coming lose and or being misaligned through the course of the race.

                  Having participated in a couple of these events I do appreciate an effort to level the playing field. However, the only way to create a truly driver/driving based competition is to make them an IROC style event.

                  It is clear in the excellent competition AND the sharing of build and preparation tips among the racers that the majority of participants are truly there to have fun. If this race is about the racers (without them there is no race) I suggest allowing the racers a democratic voice into a few of the rules. Technically...This one seems a bit like a no brainer.

                  Just my $0.02

                    First off, the spyder version has not been released as of yet and we are all waiting to see what the differences may bring as a challenge to keep both types of cars equal.

                    Now the hard part, there are a lot of considerations when creating the rules used in these types of series. Often the manufacturer has input or may push for only their parts to be used, or the race series promoter has certain considerations in mind when scoping out the general concepts of the series, there are considerations of the interoperability of various parts even from a single manufacturer, and even allowing something as simple as the gluing of bushings in place can have other ramifications that one may not even be aware of until after testing and looking at all aspects of the given assembly. We take great care in creating the rules that we present for these events and are always looking at improvements as well as preventing loopholes. We try to keep the playing field level when we can so that those that are new to the hobby/sport will not feel left out and help participation to grow.

                      I appreciate the time and effort you put into developing the rules. Most don't know how much time you devote to developing the rules and the other work you do relating to races.

                      As many in the hobby drive and tune thier cars differently, giving racers a little more latitude as far as gluing certain parts, or allowing a racer to use their preferred brand and type of tape should be allowed and can possibly expand participation in the Championships. Tuning techniques such as these that are widely accepted in the slot car community should be allowed. If their tuning technique detracts from the performance or reliability of their slotcar then if, or when the car fails, it is the racers own fault. It also would benefit the Championships if input would be solicited from previous Championship participants.

                      I agree and understand that manufacturers and the race promoter have certain requirements as far as what parts and brands of parts may be used, the rules committee should think about expanding the allowed tires to include the soft and firm compounds of the tire sponsor's tires, in addition to the sponsor's extra firm tires.

                        There are multiple car builders that are previous championship race participants (not only race winners) involved in the creation of the rules. These builders typically have different build styles and tuning techniques. Prior to rules being published, prototype cars are built using proposed rules. Cars are then tested and evaluated by multiple people. For example, for the upcoming Flyslot truck series different builds including different motors are being tested and evaluated by multiple people. Prototypes were run in a local race on the track being used for the Finals this past week.

                        As was mentioned earlier in this thread, the gluing of the bushings in place is currently being considered along with several other items that are yet to be tested.

                              I guess the use of "prototypical" describing the need to keep windscreens clear and the question as to whether or what to get the open and closed cockpits competitive with each other begs the question "Why?" The open cars ran with each other in sprint races (note lack of knock-offs, etc) and the coupes ran with each other in endurance races. They did not "prototypically" run against each other.

                              I'd suggest select one or the other. Both is trying to serve too many masters.

                              IMO, of course.
