This rule set is based on the standing SORRCA rules for Class 1 and is augmented to include super scale rc trucks into its own class to allow the ultra scale builder to compete in an event setting that is designed for rc trucks built to the extreme of scale realism. This rule set in no way supersedes standing SORRCA rules and regulations, but to add a new dimension of scale competition for local groups and clubs.
A street legal vehicle with off road style tires with little to no suspension “lift” or major suspension modification.
-No shooter shackles or Z box modifications allowed for leaf sprung trucks.
-“Modified” 3 or 4 link suspension links and coil over shocks from the factory is allowed.
Ex: RC4WD Cruizer with 4 link instead of leaf springs or an SCX10 (V1 or V2.) with a hard body attached.
-Only hard bodies are allowed. No lexan besides windshields and accessories.
-Vehicle must have a windshield that fills the entire windshield frame.
-Full width bumpers as wide as the body 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.
-The vehicles body must be mostly
intact. No trimming of flairs or fenders to accommodate tires.
Removing a hardtop are allowed. If the hardtop is removed, a full
interior is required.
-Additional pieces made be
added to the body to add length or style to the body but fenders and
wheel well openings must remain intact.
-No pinching of bodies, front
or rear. -Dovetailing is not allowed. -Sectioning or narrowing of the body is
not allowed. -Boat sides are not allowed.
-Wheels must be aligned within the body wheel wells (center of wheels to center of wheel wells +/- 1/2 inch total combined)
-Vehicle must run a full length rail chassis (The rail chassis must be as long as the vehicles wheelbase) for example: Bruiser/Mountaineer, SCX-10, Reign RC K2-3S, 3L, 4, 5, MFM, Trail, CR-01, UTE, Tamiya CC-01 chassis and tub 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.
-All vehicles must 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.
Any realistic scale looking tire measuring at or below 102mm / 4.00" size, including spares is allowed regardless of manufacturer.
-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).
-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.
-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.)
-No external tire modification is allowed in Class Zero.
-Spare tires must be the same diameter of your drive tires to receive points.
Axle and Drive Train
-Multi axle vehicles allowed and may use more than one front steering axle (front axles are considered any axles forward of the centerline of the skid), no rear steer is allowed.
-No comp style knuckle weights of any kind
Winch and Recovery
-Winches are not needed but highly recommended.
-Any functional recovery tools you wish to use during your run, you must carry it on your rig at all times. EX: 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 or winch buddy sticks supplied by the course builder.
-Winching off of a person such
as their shoe or hand is not allowed.
- Overall course design will ultimately be determined by the group or club. Know the limits of the trucks in attendance and build courses accordingly.
-3-4 courses per
event. 30-40 gates course. 2-3 hour time limit for the overall event.
-Gates will be a
minimum of 10" wide (so mind your width).
-flags, tape, banners and boundary rope may be used to mark the course such as in trials courses and mainly used to protect trucks in rocky sections.
-Stakes and/or Winch buddy
sticks are suggested for each course.
-Drivers may navigate each course at their own pace during the allotted event time.
-Drivers may complete as many courses as they like and will only be scored for the courses they ran.
-Once a Driver starts a course they must complete it to get scored for it.
-There is no DNS penalty for courses a Driver does not run.
- Drivers will self judge through the event.
-Driver will turn in their score sheet once they have completed the courses or the end time for the event is called.
-Driver scoring will be divided into 3-4 categories for the courses they completed. EX: Drivers that completed 2 courses will be scored together, Drivers that completed 3 courses will be scored together, etc.
-Half of the vehicles scale points will be applied to each course completed for final scoring.
60/30 for Class 1. 80/40 for Class Zero.
