    Class 1 rig guidelines

    SORRCA
    Scale Off Road RC Association
    CLASS 1
    2012 Official Scale Rock Crawling Competition Rules
    EPARCCrawlers Version


    Introduction:
    This rulebook is intended to standardize scale off road RC competitions that are held at various locations throughout the world. The intention is for all clubs/events to use these rules as written; however, they may be modified on a local basis. Any and all changes made to these rules at a SORRCA sanctioned event must be covered in a preliminary drivers meeting and publicly posted before the event.

    Class Descriptions:
    Class-1 “Street"


    • Description - A street legal off-road vehicle that you would drive to work or the trail head and outfit like an expedition vehicle such as the Camel Trophy truck D90 rigs.


    Class-1 “Street” Details:
    • Vehicle must have a windshield that fills the entire windshield frame.
    • Full width bumpers are required on the front and rear of the vehicle. Bumpers that are molded into the body qualify. A rear bumper is not required on a flatbed, but adding one to the flatbed will gain the additional scale points. (Bumpers are measured from the outsides and must be the width of your windshield).
    • Wheels must be aligned within the body wheel wells (center of wheels to center of wheel wells +/- 1/2 inch total combined)
    • The vehicles body must be mostly intact. Only mild trimming such as flairs & removing a hardtop are allowed. If the hardtop is removed, a full interior is required (no extreme trimming of bodies allowed *See below.)
    • The tread of the tires cannot extend outside of the wheel wells more then 1/2 of the tread width, flairs can be added to reach min. spec.
    • Vehicle must run a full length rail chassis (The rail chassis must be as long as the vehicles wheelbase) (Tamiya CC-01 chassis are allowed).
    • Truggies are not allowed, flatbeds with full length rail chassis are allowed. The bed must be as wide as the cab the entire length of the bed. Cab only not allowed.
    • Tires can never extend beyond the body’s bumpers or the rear of any truck bed. (Any stingers, fairleads, shackles, bolts, etc are not considered part of a bumper when determining this.)
    • Dovetailing is not allowed.
    • Sectioning or narrowing of the body is not allowed.
    • Bobbing a truck bed is allowed, but must follow all body specs.
    • Boat sides are not allowed.
    • 106mm / 4.19" Max tire size including spares.
    • Gates will be a minimum of 11" wide (so mind your width).

    General Vehicle Details:
    • You are encouraged to go above and beyond to make your truck as scale as possible.
    • Vehicles must resemble a real 1:1 rig. It will be up to the collective group to vote on whether a questionable rig is accepted or not.
    • Tire size will be determined by advertised manufacturer specs (tires without available specs will be measured off the truck as mounted on the wheel laid flat).
    •Tire modification:
    Class-1 Street. No external tire modification is allowed.
    • You must run a rail chassis (for example: Bruiser/Mountaineer, SCX-10, Reign RC K2-3S, 3L, 4, 5, MFM, X-Trail, CR-01, UTE, etc...) No TVP (twin vertical plate) chassis' or frame rail extensions on a TVPs. The exception to this rule is the Tamiya CC-01 or TA-02 ,(Hummer, S-10, Ford F-150 and Toyota Hilux)and Modified class Tubers.
    • 4-wheel steering or dig is allowed in modified class only (you must choose 1 per course).
    • No "Motor On Axle" (MOA) of any kind. All motors, transmissions, and other electronics (other than steering servos) must be chassis or frame mounted. Your axles must be driven by one transmission or transfer case and a minimum of two driveshafts (except CC-01, TA-02, etc) No separate throttle control of drive shafts or axles.
    • There are no wheel size distinctions. For example, you can run a 1.55, 1.9, 2.0 or 2.2 rim in any class. Wheels larger than 2.2 are not allowed in any class and no short course style wheels with split diameters.
    • Spare tires must be within 1/4" diameter of your drive tires to receive points.
    • Any functional recovery tools you wish to use during your run, you must carry it on your rig at all times. IE tow strap, pull pal, and sand ladders.
    • Winching can only be performed off of natural objects (i.e. trees, rocks, etc...), other vehicles, or stakes supplied by the course builder. Winching off of a person such as their shoe or hand is not allowed.
    • All vehicles should have the motor, transmission, and electronics covered and hidden when viewed from the top and sides. Batteries must be chassis mounted and should be hidden from view.
    • Courses will be tough and made to push the scale vehicle's limits. This is to encourage competitors to improve their rigs from one event to another.
    • Winches are HIGHLY recommended!!!!! Expect to use a winch.
    • Water proofing is HIGHLY recommended!!!!! Expect your rig to get wet.

    Tire Ban List:
    • Losi Claws (all sizes, and types)
    • Hot Bodies Rovers (all sizes)
    • Hot Bodies Sedonas
