Default Heads Up 1/24 Scale Drag Racing Rules Set

Hi Guys,

Here ya go, Carved in Stone. This is it, build em' up.

General Rules and Regulations

Cars are to be 1/24th or 1/25th scale.

Cars may not be more than 3.25” Wide at any point.

Cars must have 2 front and 2 rear wheels with black rubber tires
-Front wheel must rotate on axle
-Front wheel must be mounted vertical to track surface. Front Tire
Must project below the chassis

Minimum clearance (Ride Height) is 0.047” to track at any point, excluding tire, guide
Flag, wheelie bars and braid .

Unless specific class rules permit otherwise, all cars shall contain a
Suitably detailed, 1/24th or 1/25th scale, full-coverage interior with, at
Minimum, a three dimensional (3-D) driver with helmet, shoulders, arms
and steering wheel. The interior shall be mounted in the original cockpit
Position at all times during qualifying and racing, and shall be opaque or
Painted

Guide flag length is .980 maximum.

During event, drivers will be called to the starting line in pairs and an
Additional pair will be called to the starting line for standby. Once starting
line area is clear, driver will have 1.5 minutes to stage. The Race Director will call ALL READY before starting the Shot Clock. No lane prep can begin before this occurs.

The Driver and ONE Helper are allowed to be in the Starting line area.

Driver shall enter no more than two cars in each “heads-up” class.
Any component, except original chassis and body may be replaced
at any time. If significantly damaged, a body may be changed with
Approval & supervision of race director. Switching of original chassis
Prohibited.
If driver is found to have switched a chassis he will be
Disqualified from events as determined by the track owner/race
Director.
Any car determined a hazard to other racers or spectators can be
Disqualified from competition.


A competitor with mechanical problems during pre-staging may receive 2 minutes in which to correct the problem. Staging time will resume where clock stopped once one the 2 minute break time has expired. Proof of breakage must be presented to race director. Car must break on starting line. A car wired backwards does not constitute breakage.

Ballast/weight used to aid an entrants vehicle to make the class legal minimum weight must be secured to the chassis/body of the entrants vehicle, if any ballast or any component becomes detached it may not be “Re installed” The entrants vehicle must be weighed “as is”. If contestant’s car is found to be underweight on first qualifying session, the contestant will be allowed to participate in second qualifying session. If light on both qualifying sessions the driver will go to bottom of ladder.
If a contestant’s car is found to be under weight during eliminations the contestant is disqualified and his/her opponent is given the win if the opponent staged a class legal vehicle and received the start signal.

In a situation where a driver is making a single run, he/she will be considered the winner once the driver stages a class legal car and receives the start signal. A driver may pass a on “bye” run but the driver will lose lane choice on the next round. Car and/or driver can be disqualified for rules infractions at any point during the event including bye or single runs.

In any round of eliminations where there is an odd number of cars, bye
runs will be awarded according to official pairings for eliminations determined by official ladders. Race director is to determine pairings and bye runs in non-qualified fields.
In all heads-up categories, lane choice is determined by elapsed times. The contestant with the best qualifying E.T. gets first-round lane choice, and in subsequent rounds, lane choice goes to the lowest E.T. of the pairing in the previous round. Qualifying passes will be in alternate lanes.

In event of two identical qualifying times, faster MPH will break tie for qualifying position. If tie still exists, best reaction time will Break the tie.

Qualifying and racing voltage for all classes shall be limited to a range of 16.0 to 16.2 (maximum) volts. This voltage is to be measured at the braid unloaded, without cars on the track using accurate digital voltmeter to record the values.
No controller, choke, or push-button system used by competitors in class, index, or bracket competition shall add any power, beyond that which is supplied by the track power supply, to the track in any way.
Additionally, said devices shall not be capable of electronically or mechanically
Actuating and/or delaying reaction times in the manner of a full-sized “Delay box” or “crossover box”. To this end, the race director and/or tech Inspector may require the disassembly of any box enclosing one or more Relays and its/their attendant batteries to determine compliance with these rules.




All elimination runs are subject to the first or worse rule. When this Occurs, the driver committing the worst violation is eliminated. Should Driver receive a red-light foul start, and the opposing driver cross the Boundary line or hit side guardrail, the latter infraction prevails and the driver committing the red-light start will be reinstated. If one car crosses
And causes the other car to deslot, the car causing the crash will be Disqualified. If the cause cannot be determined, the race will re-run.
If both cars deslot independent of each other, the car crossing first will be disqualified. As long car remains in lane, car will not be disqualified. Driver is not to touch car until decision is made by race director.

A track ET record is reset when an ET run under the current record is backed up within 2% at any time during qualifying or eliminations during the event.

A track MPH record is reset when a MPH run over the current record is backed up within 2% at any time during qualifying or eliminations during the event.

Tech Inspection

The tech director/track owner will be responsible to determine if a specific body, motor, motor component etc. is eligible for competition.

Pre race tech will consist of an inspection of the body, chassis, tires etc.
Motors will be checked for armature, can & end bell type/group compliance only.

Any car may be “re – inspected” by the tech director/track owner at any time including complete motor disassembly.

A complete tech inspection with motor disassembly will be performed immediately following an ET or MPH record setting pass (back up pass), the car will be impounded until inspection is complete.

At completion of event, winner and runner up will be impounded for a complete tech inspection with motor disassembly.

If the motor or components are found to be out of specification during a tech inspection involving motor disassembly, the competitor shall be banned from competitive events.

This suspension shall last for one year from the date of the infraction.

It is the racers responsibility to insure his/her car complies with the Body, Chassis, Motor & Tire rules outlined in this rules set.
