These premier custom slot car builders have expressed interest in building for this event.  We have admired their work and can recommend them. They have all assured us that they will maintain high standards of workmanship and integrity in dealing with anyone who commissions a car or component from them.

We offer these resources to promote the craft of building custom slot cars. Nomad Raceways, Batesville Slot car and Hobbies, Slot Car Drag Race Proxy World Challenge, their owners and employees take no responsibility for any purchase or agreement between these builders and those who may commission projects from them.  All matters of pricing, quality, suitability, performance, delivery and timeliness are between builder and commissioner.

Some of these builders have a full schedule, be sure to contact them as soon as possible to allow sufficient time for cars to be delivered to the event by November 12, 2022.    Builders can apply here.

Track Tech: 
Our track for this event is Batesville Slot Car and Hobbies scale quarter mile. This is an excellent facility which holds weekly racing and frequent larger events including World Championship events drawing hundreds of entries and paying thousands of dollars in awards.  See their Facebook page.

• Slot width is 1/8″
• Braid is recessed .75mm (.030″) below track surface
• Slot depth is 9mm
• Track has Formica top
• 1/4″ wide braids

We have ample power per lane:

• Power supply 16.4 volt 100 Amperes with 50 Farrad capacitor
• Battery 25 volt 730 Amperes
• Battery 37.5 volt 365 Amperes
• Voltage will be carefully monitored to be consistent for all classes and especially within each class. Voltage will be measured at the braid unloaded, without cars on the track using accurate digital voltmeter to record the values.

27-foot shut down area is wired for brakes and has a generous application of 9 feet of Koford Light, followed by 9 feet of Koford Medium then 9 feet of Koford Heavy Shutdown Glue then a soft net and foam pad.

General rules for all classes

• Cars must meet all specification in the Class Chart.  Specifically; Body material, Motor type, Chassis type, Minimum weight, and Wheelie bars.   Cars that do not match these specifications will be moved to a more appropriate class or run as demonstration only – ineligible for awards.
• Cars are to be 1/24 or 1/25 scale except for Unlimited, Motorcycle. Just for fun and 1/32 classes.
• Maximum Car Dimensions:  Width:4” Height:7” Length from tip of guide to rearmost part:22”
• Any foam rear tires may be used.  Other tire materials may not decelerate adequately in shutdown glue.
• No part of the car may touch the track except tires, guide and braid.  If chassis is flexible, be sure it cannot cause track scraping or car may be disqualified.
• Cars will be run with braid pressed flat to guide.  We will check that braid is flat in case it has been disturbed in shipping.  If front wheels support car, and if drop arm is used, an up-stop or substantial weight is recommended to reduce braid arcing.  Cars that arc excessively or short circuit will be disqualified.
• Track sensors stage and read times based on the blade of the guide.  Guide blades must not be transparent and measure between ¼” or 6.5mm and 11/32” or 8.5mm into slot and at least ½” or 13mm long. Black plastic guides are recommended to prevent ‘No Time’ displayed or ‘Can’t Stage’ issues.  We have seen some issues with graphite guides. One guide per car.  Secondary guides on rear of car have produced crashes.
• No stored energy in car may be used for propulsion. So batteries to operate lights or animation would be OK, but no power may be added to the motor.  This rule also expressly forbids rocket or jet power.  Without electric motor braking rocket cars generally do not survive their first pass.  They also may present a fire hazard.
• Entrant shall mark Entry (Bib) Number on underside of car chassis or body.  Use Sharpie and cover ink with clear packaging tape. Doing so will help insure your car is returned to you.
• Gear choice is free.  Up to three ratios may be used by selecting the Pit Crew Option.

Motor rules:

• Motors will be confirmed as being of the type specified in the Class Chart.
• FK (short and long can) and SD type motors may not be opened or modified.
• All other types may be adjusted or modified, except that armature must be of the specified class.
• Armatures will be tested for proper resistance. Milliohms @ 65 degrees F.  ~16D: 600  ~S16D: 285
• Exception is made for Vintage and Nostalgia classes where “rewinding” armatures is permitted.
• If sending alternate motors, include correct bolts in place on motor for bolt in type. We can change solder-in types. 
• If changing crown gear size. pinions must align.  test fit on long pinions.  If pinion change is required, we recommend sending crowns and alternate motors as a set with pinions preinstalled on motor.  Changing or moving pinions on high powered motors without testing is risky.

Appearance rules:
Interiors and body details are not required, but 1/3 of total score is based on Appearance, so compromising detail for light weight will not result in the best overall score. Likewise, non-scale aerodynamic devices are not prohibited but may reduce Appearance score.

Proper classification will be considered. For example, if your car is entered in the “Stock” class but appears to be a Pro Stock body, your Appearance score will be low. To remove doubt, we recommend that you do Internet searches or provide other documentation that will confirm correct classification and details. Printed documentation if any will be presented to judges with car.  Documentation may also point out features of the slot car.  Factory produced paintwork, and details will be rated lower than unique or handcrafted work.  Note such things on documentation.

Documentation, optional display items, special tools and alternate parts or will be displayed with the car for judging.  Documentation should include Entry (Bib) number. (Not registration or transaction #)  It should NOT include builder, raceway or owner name.

Excluded entrants:
Owners and employees of Nomad Raceways, Batesville Hobbies, relatives or family members may compete for any awards or prize many in this contest.  They may send entries, to be run for demonstration which may be featured in event coverage, but not eligible for awards or prizes.

No person with a car entered in this contest may be present while their entry is judged or raced.

Any protest must be submitted within 24 hours of results published on the World Championship web page.  A protest may only be submitted by sending a $50 protest fee via PayPal to jim@nomadraceways.com.
