ROCK CRAWLING OFFICIAL RULES FOR COMPETITION

FYI only. . . . . were not going to have a competition yet. . . . just to let you know how it works. . . . .


Official Rules for Competition 2009

These rules were created to allow competitions to be held in a uniform manner at any Rock Crawling meets/competitions.

Touch: (5 pts) are given for any touching of vehicle while running on course intentional or unintentional. Vehicle repairs that don’t require tool use may be performed without additional penalty. If driver must lift the vehicle from course to inspect for damage he must notify judges before doing so.

Repair: (5 pts) points are added to touch penalties if the use of tools is required. Repairs taking less than 1 minute may be completed on course. Repairs taking longer than 1 minute must be completed off course in the pit area. If repairs cannot be made with in 30 minutes the driver is given a DNF.

Rollover: (5 pts) points are given when vehicles rollover, and cannot be corrected without touching. Vehicles that land back on their wheels are not penalized. No reverse penalties are given until vehicle is back on 4 wheels. A vehicle can only be pushed back on to its wheels from the side. Anything else is a Reposition.

Reposition: (10 pts) points are given when a driver must reposition their vehicle in order to continue. Repositions are placed back on the course without making forward progress. Judges reposition the vehicle.

[color:33b5=white]Gate Marker: (10 pts) points are given when 4 wheels do not travel between gate markers or any part of the vehicle or driver touches a gate marker. Once any gate marker has been touched, no more penalties will be given for that gate marker. (See page 4 for Gate Marker and Gate Clearing explanations.)

Back Up/ Reverse: (1 pt) point is are given when a vehicle reverses course after making forward progress. Reversing course is defined as the tires moving the vehicle backward or spinning in the reverse direction, whether intentional or not. Once a reverse penalty is given, no further reverse penalty can be given until the vehicle makes forward progress. Maximum 10 penalty points per GATE for reverses.If the reverse affects the position or attitude of the truck, it is counted as a reverse and will incur points. [See page 4 for Reverse examples and explanations.)

Maximum penalty points: The maximum points per gate is 20 points. Once a driver has reached the maximum of 20-penalty points, they will be placed past that gate. No progress points are given for the gates not cleared.

DNF (Did Not Finish): 20 points will be added for each gate not cleared for any driver cannot complete a section for any reason. (Time-Out, Vehicle not Repairable, Went Home …etc) Progress points are awarded for each gate completed.

Progress bonus. (-1 progress point) will be awarded to drivers for each gate that is cleared by the vehicle during the attempt of a stage. These points are deducted from the total stage score.

General Event Rules & Event Management


Lowest total score wins.
Scoring starts as the Vehicle breaks the plane of the first gate of a stage.
Scoring stops when the Vehicle breaks the plane of the last gate of a stage.
No pre-running the courses. Drivers that pre-run a course/stage will receive a DNF for that stage.
Starting Order will be a random draw for the first course.
The running order of subsequent courses will be run in reverse order
Winching or ramping of any kind is not allowed.
The Vehicle must finish a course in the same wheelbase, track width, ride height, and tires it started that course with.
Vehicles cannot be exchanged for another vehicle during the competition.
Drivers may make changes to wheelbase, track width, ride height, and tires may be made between course runs.

Tie Scores
Timed: In the event of a tie score the competitor with the lowest total time on all courses will be chosen the winner over the other competitor(s) with the same score.
Non Timed last course should be run again with a sudden death rule. Any penalty point ends the run and forward progress is marked. Driver progressing the furthest wins.
Timed Event Drivers must complete the course within a certain time. If a the driver fails to complete a section within the specified time frame, the driver will be assessed a DNF (20 points will be added for each gate not cleared).
Time starts when vehicle breaks the plane of the first gate of a stage.
Time stops when the vehicle breaks the plane of the last gate of a stage.
Methods of timing events may vary from club to club to meet the needs of that club. Make sure at that event drivers meeting drivers are informed of this.

Course design recommends the following course set up:
Gates with Tennis Ball halves
Minimum of 20 inches apart
(3-10) Gates per section
(1-3) Stages per course
Gates that are close proximity to each other should be distinguished by color or markings.

Judging
Judges are responsible for watching vehicles while on the course, and to penalize drivers that commit penalties while competing.
Judges should call out penalties when they occur.
Judging should be done by at least 2 people per driver. One Judge to call out penalties and one Judge/Score Keeper, to record penalties, tally maximum penalties, keep time (if applicable) etc.

Definitions, Examples & Explanations
Event/Competition: The coming together of drivers at a certain place and time to compete on single or multiple courses.
Course: A course is all the terrain that competitive driving will take place on, and may be comprised of single or multiple stages.
Stage: A stage is the terrain that consists of a start gate, an end gate, and all the terrain in between them. Every stage has an intended direction of travel, or “flow”, through the gates.
Gate: A gate is used to mark an obstacle within a stage and/or guide the vehicle through the stage. A gate consists of 2 gate markers measuring no less then; 20” for Class 1 & 3 and 16” for Class 2, from inside edge of one marker to the inside edge of the opposite marker. Every gate has an intended direction of travel, or “flow”, through the gate. This direction will either be, marked, explained or implied by the course designers. ALL gate markers are “alive” until touched.
Wheelbase: is measured from axle nut center to axle nut center.
Vehicle track width: is measured from the outer most edge of a tyre to outer most edge of a tyre.

Back Up/ Reverse Examples:
If the driver intentionally drives the vehicle in reverse, a reverse penalty will occur.
If the vehicle stops on an incline and then rolls backwards a reverse penalty will occur.
If a vehicle is stuck or stopped a reverse penalty will occur if the tires move forward at all and then move backward. Even if the vehicle does not move (this includes dig steering).
If a vehicle is climbing an obstacle and is bounced backward by the terrain but the tires are still moving forward, No reverse penalty will occur.
If a vehicle flips over backward, without the driver reversing, no reverse penalty will occur.
Once a reverse penalty has been assessed, no further reverse penalty can be assessed until the vehicle makes forward progress. (Example) Reversing, stopping, and then reversing again will only result in one reverse penalty.
Reverse penalties are assigned at the Judge’s discretion if the actions performed by the vehicle/driver are not clearly defined by the rule.
If the vehicle is on its side and reverse is used that moves the truck then this results in a reversing penalty, if the trucks wheels are not in contact with the ground and the wheels move backwards but the truck does not move no penalty is incurred.

Gate Marker penalty and the Clearing of a Gate:
A gate is considered cleared when one or more wheels from each axle passes between two gate markers in the intended direction or the gate. A Vehicle may travel through a gate while it is in reverse and still clear that gate (reverse penalty(s) will be assessed as necessary) as long as it travels though in the intended direction of that gate.

(Example 1) If all four wheels of a vehicle passes between two gate markers that gate is considered a cleared gate with no penalties and a gate progress bonus is awarded.

(Example 2) If one wheel from the front axle and one wheel from the rear axle passes between two gate markers (vehicle straddles a gate), that gate is considered a cleared gate. This however will result in a Gate Marker penalty of 10 points.

(Example 3) If one wheel only from the front axle or one wheel only from the rear axle passes between two gate markers (vehicle straddles a gate) that gate is not considered a cleared gate. This will result in a Gate Marker penalty of 10 points.

At any time a gate marker is touched by a vehicle or by a driver, or when the vertical plane of a gate marker is breeched by the wheel/axle, a Gate Marker penalty is assessed and that gate is deemed “touched”.
At any time a wheel does not pass between gate markers (i.e. straddles a gate marker) a Gate Penalty is assessed.
Driver can only continue with the stage when a gate is cleared or 20 pts at that gate is accumulated.

Thanks Richard, was looking for simple set of rules!

thanks sir chard.. that cleared most of my questions...

BTW how about the RIG??? is there any standard set of rules aside from the 2.2 tires you're using now? what about the motor and weight?

this can affect my crawler project..hehehehe

thanks for sharing sir chard, now we have an idea about competition rules . . .

same query as Jracing, any regulations or limitationsand class on rigs???

is there any classification using 1:8 and 1:10 rock crawler?

VEHICLE REQUIREMENTS

Class 1 - Super Crawler Class:
- Vehicle wheelbase is limited to a minimum of 16 inches and a maximum of 18 inches. This is

If you want the complete USRCCA RULES 2009 download the PDF here.

so our RIGS fall under the 2.2 class. . . . . .

All those looking at getting crawlers, lets try and stick to 2.2 class for now!

super class can become one of those classes which gets very expensive very quickly as there are few restrictions, and it becomes a competition of who has the biggest wallet, with a bit of skill! hahaha

thanks sir chard your the man! :cheers:

its been almost a year since chardiboi posted this thread and i just thought of updating it since a lot of people are getting into crawling ....

i'd like to bring this thread TTT so we can run a simple 2.2 comp sometime soon ...

i can bring the gate markers and the score sheets .... i already have them cos we use them here in alain while hitting the rocks up ...




weather is permitting and since the dubai boys have got 2 very nice crawl areas now .... i dont mind driving down to crawl with you guys ...


click on the link below for the 2010 RC Crawling Rules ..... we can focus on 2.2 and sportsman so more people can join in have fun
