Advance Class Rules and Regulations

Advance Class

Rules and Regulation

 

Golden Rule:  All Tamiya Cars and parts only.

 

Welcome to the Brickyard Advanced Class Racing.  Please read the guide carefully.  This will serve as our rules and regulations.  These rules will be strictly implemented.  In general, the configuration of these cars are similar to the starter packs.

The most important rule once again, ALL TAMIYA only!

  1. ***ALL TAMIYA ONLY***. **This will be STRICTLY enforced through inspection before every race. If it is determined that a car contains "non-Tamiya" parts, the car and racer will NOT RACE that heat and will be considered as having lost the heat. While it is acceptable to paint parts, if the inspector’s are unable to identify that it is an original Tamiya part, the inspector may conclude that it is NOT A TAMIYA PART. The inspector's decision is final.
  2. One car per racer only. We register the racer, not the car.  A racer can only register ONE CAR per category.
  3. Alkaline (1.5V) or Rechargeable batteries (1.2V) are allowed. Be advised that there may not be enough outlets in the venue. We will not be able to provide additional outlets. Please bring enough batteries.  For Asia Challenge, only Fujitsu alkaline batteries will be allowed!
  4. This will be the Brickyard Advance Class. In general, the configuration of this class is similar to starter packs.
  5. Rollers: Maximum of 6 rollers.  No Aluminum rollers are allowed.
  6. FRPs: Maximum of 3 allowed (1 - front,1 - rear, 1 (pair) - side)
  7. All High Grade parts are not allowed.
  8. Bearings of any kind are prohibited.
  9. EVO parts and kits not allowed.

Parts are to be used for what it was intended.  You can not use parts for a different purpose. 

 

 The above takes precedence over the following rules.

     1.  Usable Machine Types

Only Mini 4WD REV, Mini 4WD PRO, Racing Mini 4WD, Super Mini 4WD, Fully-Cowled Mini 4WD, Aero Mini 4WD, Mighty Mini 4WD, R/C Mini 4WD, and Truckin' Mini 4WD machines are permitted. Further restrictions on machine types may be possible depending on the race event or race class. 

  1. Machine Assembly

All machines must be four-wheel drive. Modifications that result in rear-wheel or front-wheel drive are prohibited. Bodies should have stickers applied or be painted, and must be securely attached to the chassis. 

Please be warned that bodies which are particularly small, or those which it is difficult to check are painted or have stickers applied, may be prohibited. Home-made bodies are prohibited. All machines must go through car inspection and machines that do not pass inspection cannot participate in the race. As a general rule, machines must be assembled by the racer. Some exceptions may be applied. Please ask Race Officials.

  1. Machine Measuring System

All machines must have a 4WD setup and will be subject to the same measuring system as shown below.

  • Maximum Car Width: Under 105mm
  • Overall Car Height: Under 70mm
  • Overall Car Length: Under 165mm
  • Minimum Ground Clearance: At least 1mm

  • Rollers: Maximum 6 rollers.
  • Mass Dampers: The installation positions of rotating mass dampers are no longer limited.

When adding parts to the bumpers, side guards or the chassis, please note the zone restrictions below.

※Definition of Bumpers - For MS chassis, the bumper is the section on the Front or Rear Unit not including the Bumperless Unit. On other chassis, bumpers are the sections forward and rearward of the front and rear gearboxes respectively.
※Definition of Side Guards - Parts that extend from the sides of the chassis between the front and rear tires.

  • Parts which extend around the outside of the wheels to completely frame the chassis are not allowed.
  • Parts attached to the front bumper cannot extend past the line of the front axle.
  • Parts attached to the rear bumper cannot extend past the line of the rear axle.
  • Parts attached to the side guards must remain within the lines shown: (back edge of Front Tire & front edge of Rear Tire)
  • Chassis: Extension parts which are attached to the chassis itself are subject to the same zone restrictions as similar parts attached to the bumpers or side guards.

※There are no rules for parts which pass above or within the outside edges of the tires.
※There are no rules for mounting rollers, etc. to the body as long as they are above the level of the wheel axles. If they extend below this line, they will be subject to the same limits as parts which are attached to side guards.

Any other questions, please ask the inspectors to settle before the race. 

 

Race Courses 

For courses which satisfy the below specifications and are sanctioned by Tamiya, times recorded during races will be officially recognized. All times recorded on original courses that do not meet these requirements will be considered unofficial.

  • Individual Lane Width: 115mm (measured on a straight section)
  • Course Wall Height: 50mm (measured from road surface)
  • Adjusting the height and lane width of lane change sections, bank turn sections, etc. for smoother racing operations is permitted.

For Competitions at Official Race Courses 

  • The start of the race will be indicated by a signal from a Tamiya race official or a starting signal system. Racers will switch on their cars, hold them in the air with one hand, and drop them vertically into their assigned lane at the start signal. Throwing or pushing the car forward is prohibited.
  • A racer will immediately retire from a race if their car leaves the track, flips over, jumps into another lane, or if their car's body detaches during the race.  The race marshals will have the final discretion whether to pick up a car that is no longer upright on the track.   
  • If race officials determine that a racer's car is blocking the progress of faster machines, the racer will be required to retire.
  • A car's race is completed when it reaches the finish line.
  • Qualifying and Final positions are determined by either the race finishing order or Time Attack time.

Car Inspection

  • All racers must have their car inspected by race officials before the race. If any part of the car is determined to be against race regulations, the racer will be considered to have lost the corresponding heat.  If the racer has not reached his/her maximum loses, the racer may make the required modifications and participate in the racer’s next heat. 
  • From the time the car passes the car inspection to when the race begins, the car's settings must not be changed and no modifications can be made.
  • In addition to the pre-race car inspection, other car inspections may occur at any time during the race day at the race official's discretion. If the car is found to be in violation of the race regulations at any of these inspections, the racer's race results up to that point will be disqualified and the racer must make necessary changes in order to participate in subsequent races.
  • If a machine does not pass car inspection, and cannot be made race-legal, the participant can still take part in the Qualifying rounds for their own benefit, but their times and standings will not be recorded.

Disqualification

If any of the following situations occur, race officials will, at their discretion, have absolute authority to disqualify any racer. Please take care to remember the common manners for a Mini 4WD race to avoid any problems.

  • A racer's car is determined to have modifications that will cause physical harm to other racers, other cars, or the race track.
  • A racer's car is determined to have modifications that are designed to deliberately obstruct other cars.
  • A racer deliberately puts grease or other substances onto the track to affect track surface conditions.
  • A racer is determined to have modified their car after it had passed the car inspection including, but not limited to, removing O-ring from rollers.
  • A racer is determined to have deliberately touched the track or cars to impede other racers' race progress.
  • A racer does not follow the instructions of race officials or otherwise impedes the operations of the race track.
  • A racer has a false start, or is determined to have thrown or pushed their cars forward at the start of a race.
  • A racer is determined to have acted against the spirit of fair play or caused distress to other participants.

  2. Race officials reserve the right to announce the use of special regulations at any time during the race.

Participant Restrictions

  1. Please be aware that some races have age limitations, so it may be that some participants cannot take part in certain classes or races.

Except for endurance races, it is against regulations to have more than 2 racers using the same car.
