The rule structure provides levels of competition for beginner and advanced together without favoring either while fostering an atmosphere of fun for all.

We sanction drag races on HO scale (1/64^th to 1/87^th) drag strips ranging from 1/8^th mile to ¼ mile.

Track guidelines:

1. Track surface may be plastic, wood or composite.
2. Suitable shut down space must be provided.
2. Track timing shall be computer controlled and capable of accepting dial-in handicapping or an index to control starting lights.
3. No mechanical devices shall be used to determine winners, nor starting violations.
4. Adequate pit space must be provided for competitors.

Certain local track preferences may be admitted provided they are within the overall vision of the HOHRA and HO Racing Association of St. Louis (HORA-STL).

These apply to all classes of cars

5. Cars must be drag strip appropriate body (zero tolerance).
6. No portion of the cars chassis may contact the track surface when at rest other than the guide pin and pickups.
7. Wheelie bars or similar devices must be constructed in such a manner that they do not cause harm to either the track surface or other competitors for those classes where allowed.

Stock

T-Jet (as defined by the HORA-STL)

- No modifications allowed.

- only original Aurora T-jet brass rivet style chassis,

- slip-on silicone tires (may be glued to rim)

- press-on small diameter T-jet wheels only

- magnets must be T-jet and pass HORA-STL strength test (weighted device)

- may not exceed 1.0 volt on an HORA-STL approved testing dyno for 5 seconds

Brackets (or Index)

T-jet

A/FX

- AFX or Magnatraction type chassis

- must be clip-on style hard plastic body

- any motor/chassis modification allowed provided it is AFX (or derivative) based

-body may be modified provided it contains at minimum a front windshield

Open

- You brung it, you run it!

- must be a drag appropriate body

- only true scale appearing and functioning (rolling surface) wheelie bars are allowed

- max. width is 1.4375"

Any type is permitted provided it does not:

- accumulate any type of electrical charge either from the track itself or any type of outside power source

- contain any sort of electrical storage device

- no ancillary (black box) device maybe used that is not made available (opened) for inspection upon request.

Points are awarded according to the HOHRA Point Schedule. At the conclusion of the racing season/year, we will name the winners from classes that were run as a series over the year.

An overall winner is determined as follows: When 7 or less events are held, the worst (lowest # of points scored at a single event) result for each entrant will be dropped. If there are 8 to 10 events, the 2 lowest will be dropped. For 11 or more events within a season/year, 3 will be dropped.

All entrants will receive box plates (brass ¾" x 3" plates) at each sanctioned event.

Top Eliminator, Runner-up, Top Qualifier, record ET’s receive special plates designating their accomplishment.

The HOHRA will award a "traveling trophy" with the "T-Jet Brackets" overall winner’s name.

A "Top Dragster" will be crowned at seasons/years end also and receive a trophy if other classes were also ran during the past year.

For events in conjunction with the HORA of St. Louis, the primary format to be used will be the "Double 32 Eliminations" and the primary class raced will be T-jet Brackets at each event. An "event" is defined as a scheduled HOMRC race date.

Depending upon time available, number of potential entries and racer interest, one of the following 4 formats will be used for secondary informal non-points classes at any event. For race dates other than regularly scheduled HOMRC events, other classes maybe used for specific point series on a rotational basis (different class at each event).

Quick-16 Eliminations

Only the fastest 16 cars enter into elimination (caveat: if fewer than 16 drivers/entrants, than a 2^nd car (next fastest) may be entered to fill out the 16 car field.

Single elimination format (one loss)

Top 32 Eliminations

Only the fastest 32 cars enter into elimination (caveat: if fewer than 32 drivers/entrants, than a 2^nd car (next fastest) may be entered to fill out the 32 car field.

Single elimination format (one loss)

Double 16 Eliminations

Only the fastest 16 cars enter into elimination (caveat: if fewer than 16 drivers/entrants, than a 2^nd car (next fastest) may be entered to fill out the 16 car field.

Double elimination format (two losses) uses the first round losses (and subsequent race losses when it is that racers first loss with a specific car (if more than one is entered)) to fill out the "Loser’s Bracket" side of the elimination tree.

Double 32 Eliminations

Only the fastest 32 cars enter into elimination (caveat: if fewer than 16 drivers/entrants, than a 3^rd car (next fastest) may be entered to fill out the 32 car field.

Double elimination format (two losses) uses the first round losses (and subsequent race losses when it is that racers first loss with a specific car (if more than one is entered)) to fill out the "Loser’s Bracket" side of the elimination tree.

Qualifications

All cars presented for competition must first pass technical inspection. Those passing are then allowed to make qualifying runs.

Qualifying order is done on a first come, first served basis or random order with each entrant completing one qualifying run in each lane to determine seed placement in the Eliminations tree.
