Default Current reworked rules.

1.9” Class
This class is modeled after typical street-legal off-road vehicles, non-trailered vehicles. These rules are set up to judge a scale truck as the "sum of its parts." The goal is to have trucks that resemble something you might actually see driving down a highway on the way to the trail. Understand the "spirit" of the rules and work within them.

> Chassis: The chassis or frame must be a ladder style and extend over the axles. Competition style RC rock crawling chassis are not allowed. This includes twin vertical plate designs (TVP), "stick" style, torsion and forced articulation. Tub style chassis are allowed.


> Wheels & Tires: Wheels are restricted to OEM 1.9” size. If the tires are cut down 2.2’s, they must fit onto a standard 1.9” rim and not exceed 4.25” in height and 1.75” in width. Flywheels brand wheels and tires and 1/18-scale Nylint brand wheels and tires will be allowed. 2.0's wheels are allowed as long as the tire attached is either a stock 1.9 tire or cut & shut tire that falls into the restrictions.

> Body: You must run a complete body, bumpers, fenders, doors and tailgates must be intact. Moderate fender trimming is allowed, but the basic shape of the fender must be retained. If no doors are run, the vehicle must have an interior (dash, floorpan, seats, etc). If no tailgate is used, the bed must be built out (drop bed). A shortened or lengthened body is allowed. A tubed bed must have a functional bed area capable of carrying a full-size spare laid flat, and tail lights(need not function), (rear fender and tailgate rules to not apply to tubed beds).

> Steering: 4-wheel steering is illegal.

> Drivetrain: A chassis mounted transmission and/or transfer case are allowed. Front or rear dig, cutting bakes, motor on axle (MOA) designs are illegal. Chassis with single or dual integrated motors are allowed, but the motors must always be powered (no electronic digs).

> Wheelbase and width: The dimensions of the vehicle are limited only by the body, but it must fit within the body’s fender wells.

> Comp-day modifications: The vehicle must be run as it was setup for tech inspection.

> Battery: The Battery must be placed on or within the chassis.

2.2” Class
This class is modeled after typical off-road use vehicles, non-trailered vehicles and trailered vehicles. These rules are set up to judge a scale truck as the "sum of its parts." The goal is to have trucks that resemble something you might see driving on a trail. a purpose built off road vehicle (mud truck, hardcore trail truck, non competition rock crawler, ETC.) Understand the "spirit" of the rules and work within them.

> Chassis: The chassis or frame must be a ladder style and extend over the axles. Competition style RC rock crawling chassis are not allowed. This includes twin vertical plate designs (TVP), "stick" style, torsion and forced articulation. Tub style chassis are allowed.


> Wheels & Tires: Wheels are restricted to OEM 2.2” size. all OEM tires are legal, any modified tires may be no larger then 5.5"

> Body: You must run a body, fenders, doors and tailgates must be intact. Moderate fender trimming is allowed, but the basic shape of the fender must be retained. If no doors are run, the vehicle must have an interior (dash, floorpan, seats, etc). If no tailgate is used, the bed must be built out (drop bed). A shortened or lengthened body is allowed. A tubed bed must have a functional bed area capable of carrying a full-size spare, and tail lights(need not function), (rear fender and tailgate rules to not apply to tubed beds). All vehicles should be able to accommodate a minimum of a driver and passenger(no single seat buggys)

> Steering: 4-wheel steering is illegal.

> Drivetrain: A chassis mounted transmission and/or transfer case are mandated. Front or rear dig, cutting bakes, motor on axle (MOA) designs are illegal. Chassis with single or dual integrated motors are allowed, but the motors must always be powered (no electronic digs). A switchable transfer case is allowed, but only between 4x4 and 2x4 (rear wheel drive).

> Wheelbase and width: The dimensions of the vehicle are limited only by the body, but it must fit within the body’s fender wells. Width is unrestricted.

> Comp-day modifications: The vehicle must be run as it was setup for tech inspection.

> Battery: The Battery must be placed on or within the chassis.

>·No truck will be allowed with a RTI score over 500* measured from the bottom of the tire.

>“Tuber” vehicles will be addressed on site and maybe allowed to run in this class but no guarantee is given. All tubers must have at least a hood, grille, and side panels. Tubers should try to adhere to the spirit of "scale" and look as realistic as possible.

*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 bottom of tire. 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. Speed is rewarded.

Reverse + 1 point
Rollover + 5 points
Gate + 5 points
Touch + 5 points
Time: - 5 points (awarded if course completed in time allowance: An additional -5 points will be awarded to the fastest time)
DNF + 40 points + 5 points per gate not completed
*Rescue - 5 points

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 not already cleared 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. Gate must be cleared in its intended direction. Winching through a gate is allowed. Once a gate is cleared that gate is dead.

Touch: Any contact made to the vehicle by any person during a run. If the touch is resulting in the vehicle being placed back on course the vehicle may not be placed any further forward than the most recent point of progress.

Winch: Winches may be used at any time along the course without penalty unless any part of the winch touches a gate. If that occurs a gate penalty will be assessed.

Time: A 5:00 minute (or 1 minute per gate) 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.

*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.

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

-5 Points (up to a maximum of 20 points)
·Hard body (rigid construction, usually abs or polystyrene: essentially any body that is not lexan)
·Detailed Bed (drop beds, flat beds, tube beds: should be realistic representations)
·Interior detail (must have at least driver & passenger seat, dashboard, & steering wheel)
·Offroad trailer (must be towed during entire event)

-3 Points (up to a maximum of 15 points)
·Roof rack with large scale item (canoe or similar, item must be secured to rack with tie downs; no Velcro will be permitted.)
·Bed item with large scale item (quad, dirt bikes or similar, item must be secured with tie downs; no Velcro will be permitted.)
·Realistic bumpers (point per bumper)
·Functional winch (per winch, front or rear)
·Functional spare tire (should be same size as being run on vehicle; i.e. no 1.9 spare on a 2.2 vehicle)
·Scale engine (i.e. Parma hemi)


-1 Point (up to a maximum of 10 points)
·Functional Lights (per set: Headlights / tail lights / roof / rollbar / crawling)
·Driver / Passenger 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. 1 point per person)
·Spare tire (non functional)
·Non Functional Winch (per winch, front or rear)
·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})


Custom Body Bonus: This bonus is awarded for custom build work done to a body, this ranges from stretching, widening, combining, and scratch building. This is added on top of Scale points.

-5 points for any major custom body work (i.e. building a crew cab, grafting lexan and hard bodies*, etc)
-5 points for major tubular work. (i.e. full exocage, full tube chassis that supports and/or conforms to the body)
-10 points for scratch builds (i.e. building a body from the ground up; no OEM basis)

*50% rule applies to lexan/hard combos; in the case of a lexan/hard combo the body will be judged on the basis of whether it is more than 50% lexan or more than 50% hard.

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.

Mud Bog
This can be run as a timed or gated course. Typically set up as a drag style race, straight course, first to finish or furthest distance. It's up to the host club to decide how run and set up this event.

this needs added to the 2.2 section.

*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

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 bottom of tire. Use that measurement to determine RTI score.

I think we had agreed to change measured from the wheel nut to the bottom of the tire...
