Default North Texas Scale Crawlers: Class Descriptions

Here is a comprehensive list of the 3 classes for 1/10 scale crawlers:

2015 Official Scale Rock Crawling Competition Rules

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.
  • Class-2 Trail: Tire lugs may be removed, siped, grooved and/or trimmed.
  • Class-3 Modified: Tire modifications are permitted, as long as the tire is no larger than 5.95" in diameter measured off the vehicle laying on its side, and all tire parts are from a legal scale tire.

General Specifications:
  • You must run a rail chassis (for example: Bruiser/Mountaineer, SCX-10, Reign RC K2-3S, 3L, 4, 5, MFM, XTrail, CR-01, UTE, etc...). No TVP (twin vertical plate) chassis' or frame rail extensions on a TVPs.
    Multi axle vehicles allowed in all classes and may use more than one front steering axle (front axles are considered any axles forward of the centerline of the skid), rear steer only allowed in modified class, C3.
  • 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 drive shafts (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.
  • 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.

Tires should be scale appearing, if it is questionable have it reviewed before the event, or plan to run a different tire. As new competition specific tires are released this list may be updated.

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-2 "Trail"
  • Description - A stock vehicle that has been modified to become a capable trail rated rig and is not necessarily street legal.

Class-3 "Modified"
  • Description - An off-road vehicle that you would build from the ground up and might see in a TTC/KOH type competition.

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. (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).

Class-2 "Trail" Details:
  • Body/cage work must be at least 4.5" tall (including boat sides).
    The distance between the inside of the tires (of any axle) can be no greater than .5" more than the width of the body at the doors. *Example* (7" inside-of-tire to inside-of-tire = body must be 6.5" wide)
    Body must be at least as long as the chassis rails.
  • A front bumper is required and must be mounted to the vehicle's rail chassis and must be wider than the outside of the chassis rails (chassis cross rails do not count as bumpers).
  • You must run a full rail chassis, and the chassis (including bumpers) must be 3" longer than the wheelbase (this includes a chassis with a truggy rear frame).
  • Truggies are allowed. You CAN replace the ladder frame behind the cab with tube, but are not required to have a full tube rear section. Truggy rails must extend past the rear axle pumpkin to be legal. The bed must have a roll bar hoop and integrated shock mounts. It also must be a structural part of the rear of the vehicle. (If your bed does not meet ALL of the preceding criteria, it does not count as a truggy bed).
  • Flatbeds that run the full length of the rail chassis are allowed. The bed must be as wide as the cab the entire length of the bed.
  • 2 of the 3 following modifications are allowed:
    Dovetailing the rear
  • a truggy/tube bed that is narrower than the cab counts as a dovetail
  • (1/2 the width of the widest part of the cab).
    Boat sides (no more than 1.25" measured vertically from the bottom of the skid).
    Pinching the front (2/3 the width of the widest part of the cab).
  • 120mm / 4.76" max tire size with a 2.2 max rim size including spare.
  • Gates will be a minimum of 12" wide (so mind your width).

Class-3 "Modified" Details:
  • 146mm / 5.95" max tire size with a 2.2 max rim size (including spare).
  • A bumper is not required, but if you do have one it must be mounted to the vehicle's chassis and wider than the chassis rails (chassis cross rails do not count as bumpers).
  • Gates will be a minimum of 14" wide.
  • Class 3 body minimum specs:
    Rock sliders, mirrors, etc. do not count in these measurements:
    The distance between the inside of the tires (of any axle) can be no greater than 1.25" more than the width of the body at the doors.
    *Example* (7" inside-of-tire to inside-of-tire = body must be 5.75" wide) ? The body must be at least 5" wide from the front to the rear of the doors.
    Tire height can be no more than 0.5" taller than cab height. Height is measured from the bottom of the skid to the top of the bodywork/tube not including a light bar.
    *Example*(5.5" tire = 5" tall from bottom of skid to top of cab/tube work) ? Body must be at least as long as the wheelbase of the vehicle.
    Body modifications including, but not limited to, pinched front, dove-tailing and boat-siding are permitted as long as the final dimensions comply with the minimum size rules.

Might rename "Street" as "Scaler" as that is a little more accepted nomenclature and limit the wheel to 1.9. 2.2 is generally the wheel size for the class 2 and 3.

There will be a total of 6 Comps over the next 6 months. They are:

Comp 1: Saturday: November 7th at Big Rock Park
This is the first event in the series. We hope to get a good feel for the group and the overall skill level.

Comp 2: Saturday: December 5th at Big Rock Park
This one will be south of FW 30 miles or so!

Comp 3: Saturday: January 9th at Duck Creek
This event will not be a huge challenge for the Class-3 trucks. Please plan on your Class-1 & 2 being your primary trucks.

Comp 4: Saturday: February 20th at The Colony
This will be a proper G6 in the woods. Lots of climbs and chances of water. Pushing the limits of your rig will win this event.

Comp 5: Saturday: March 12th at Murrell Park, Day Use...
This venue is still up in the air. We are working with the CoE to coordinate this event.

Comp 6: Saturday: April 9th at Lavon Dam
Not fluffy friendly. Steep climbs and switchbacks. MAX 30 to 20 gates

Default Information on Competitions

Can you tell me where to find out more information on the Comp's. I am new to the hobby but want to go and see how it works as well as enter into the fun. I have two Crawlers I have built but having trouble finding out when and where comps are held and how to sign up or just go watch so I can sign up in the future. Thanks for your assistance
