The intent of these rules and requirements is to provide a standard set of
guidelines for any scale competition held, official or unofficial.

Scale Class Requirements:

1.9” Class – Modeled after typical street legal off-road vehicles

• Chassis must be OEM stock or custom ladder style that must extend over the axles. OEM suspension may be modified in any way. Construction material is not restricted.
• Tires are restricted to OEM 1.9” size. If the tires are cut down 2.2’s the they must fit onto a standard 1.9” rim and not exceed 4.25” in height 1.75” in width. Flywheels brand wheels and tires and 1/18 scale Nylint brand wheels and tires will be allowed.
• Must run a complete body, bumpers, fenders, doors & tailgates must be intact. Some fender trimming is allowed but the basic shape must be retained. A shortened or lengthened body is allowable. A tubed bed must have a functional bed area capable of carrying a full-size spare laid flat (rear fender and tailgate rules to not apply to tubed beds).
• No 4 wheel steer.
• No axle “dig”
• Wheelbase and width is limited only by your body, but it must fit within the body’s fender wells.
• Vehicles must be “run what ya brung.”
• Battery must be placed on or within the chassis.

2.2” Class – Modeled after modified but street legal off-road vehicles

• Chassis must be a ladder style chassis. Construction material is not restricted
• Tires are restricted to any commercially available 2.2” tire or any tire cut down to fit a 2.2” wheel.
• Must run a complete body, bumpers, fenders, doors & tailgates must be intact. Some fender
trimming is allowed but the basic shape must be retained. A shortened or lengthened body is allowable. A tubed bed must have a functional bed area capable of carrying a full-size spare stored in the vertical position (rear fender and tailgate rules to not apply to tubed beds).
• No 4 wheel steer
• No axle “dig”
• Wheelbase and width is limited only by your body, but it must fit within the body’s fender wells. • Vehicles must be “run what ya brung.”
• Battery must be placed on or within the chassis.
• “Tuber” vehicles will be addressed on site and maybe allowed to run in this class but no guarantee is given.
• No truck will be allowed with a RTI score over 500*

All vehicles and drivers should adhere to the “spirit” of a street legal off-road vehicle.

*When a RTI scale is available then all 2.2 scale trucks will be qualified with a RTI score. The scoring method is as follows: Vertical distance traveled up the scale (measured from the ground to the wheel nut) divided by wheelbase multiplied by 1000. For example the distance traveled up the ramp is 5” the wheelbase is 10.5” (5 / 10.5 = .4761) .4761 * 1000 = 476.1 (round off) 476 would be the final RTI score. If no RTI scale is available then a manual method may be used to determine RTI score. Raise one wheel up with your hand. At the height where another wheel starts to loose contact measure the vertical distance between the ground and wheel nut. Use that measurement to determine RTI score. Points:

Scale Class: All rigs in the Scale class will start off with 0 points and points will be deducted during the competitions. The object is complete the course without incurring points. Point deductions are listed below. There is no time limit and no maximum point limit. Speed is rewarded.

• Reverse + 1 point
• Rollover + 5 points
• Gate + 5 points
• Touch + 5 points
• Reposition + 10 points
• Rescue - 5 points
• Time - 5 points
• DNF + 40 points + 5 points per gate not completed

Reverse: Using the throttle to reverse course. Non powered roll backs are allowed. During gated courses each driver is allowed 1 reverse per gate without penalty.

Rollover: Points are assessed when a vehicle rolls over and does not right itself or can not be righted without touching. Winching is allowed without incurring a penalty. Once righted the vehicle must be driven back into position. All gates are still live while on a gated course.

Gate: Failure to pass all 4 wheels through a gate or touching a gate with any part of the vehicle. Winching through a gate is allowed.

Touch: Any physical contact with the vehicle while on course. If a repair must be made then the vehicle maybe touched, however the vehicle must be placed back into the position it was in prior to repair. No touch penalty will be incurred when setting up a winch or tow straps as long as the vehicle is not repositioned or moved.

Reposition: Penalty is incurred when the vehicle must be physically moved. This includes picking up the vehicle or a rescue by another vehicle. If a reposition requires the driver to touch the vehicle then a touch penalty is also incurred.

Rescue: Using another vehicle to free a vehicle on course. The rescue vehicle will only be allowed during runs in which the buddy system is in place. The rescuer will receive the bonus points while the rescued will incur a reposition penalty.

Time: A 5:00 minute time limit can be applied per run, this is not required and will be at the discretion of those judging the courses.

DNF: If a vehicle is unable to complete the course regardless of reason a DNF will be assessed. If a DNF is assessed then they will be scored with +40 points add to their current point total plus 5 points for every gate not completed.

Buddy System: When the buddy system is in use 2 vehicles will run the course, the leading vehicle is the one being scored during that run. The “buddy” is the follower and will not be scored unless a rescue is requested. After the course has been completed the drivers will reverse order and the “buddy” now becomes the leader. Driving order will be decided by a coin flip. Buddy pairing will also be decided by chance. Method of determination will be decided on site based on number of participants. Events

Events will vary from location to location. Below is a compilation of approved events with brief guidelines. A time limit of 5:00 minutes per course can be implemented if desired.

Gated Trail: This is pretty much self explanatory. Each course will vary in length but will typically be between 5 and 10 gates. The width of each gate will vary depending on the location but generally the width should be no less than 12 inches.

Hill Climb: Once again this is a fairly straight forward; with a location selected you will simply have a start and finish. Fastest time wins; if no one completes the course then furthest distance wins. *Gates can be added to this event.

Time Trial: This event will be determined by terrain. This will be a multi-terrain event. It should comprise of at least 3 various types of terrain. For example a course may begin with a rock crawl section, proceed to a hill climb section and then finish up with a high speed dirt road section. The fastest time will be the winner. *Gates can be added to this event.

Trail Ride: This is not a competitive event it is intended to be just for fun. One driver leads the pack through whatever terrain and obstacles he/she chooses. This event is all about fun, camaraderie, and testing your vehicles capabilities.

*If gates are added to any course then the standard point system applies and the driver with the fastest time is awarded the time bonus. The driver with the fewest points is then the winner.

Scale appearance

Scale appearance points will be deducted from the final score of each event. Appearance points are listed below.

-5 Points
• Hard body (rigid construction, usually abs or polystyrene: essentially any body that is not lexan)
• Custom pick up truck bed (i.e. building a full bed from styrene on your lexan or hard body.)
• Interior detail (must have at least driver & passenger seat, dashboard, & steering wheel)

-3 Points
• Roof rack with large scale item (canoe or similar, item must be secured to rack with tie downs; no Velcro will be permitted.)
• True form bumpers installed on a lexan body. (i.e. installing a clod or blackfoot style bumper on a lexan body) *Applies only to lexan bodies, scores for each bumper.
• Leaf sprung suspension front and rear.
• Scale engine (i.e. Parma hemi)
• Tube style bed.

-1 Point
• Lights
• Driver figure (should be scale in size, in other words a 4 inch G.I. Joe figure in a 1/6 scale truck wouldn’t work)
• Leaf springs on only front or rear.
• Spare tire (must be functional)
• Winch
• Scale accessories** (jerry cans, cooler, snatch straps, etc {multiples of a particular item will only score once: for example if you have 2 jerry cans you will only score for 1 jerry can})

** NOSTR Scale Accessories Rule (See Above Rule) are capped to maximum of 5 points total
