• Vehicles must resemble a real 1:1 rig and 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-3 Modified. Tire reduction and narrowing is permitted, as well as all modifications listed above.
• 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.

• All vehicles without an enclosed cab must have the motor, transmission, and electronics covered and hidden when viewed from the top and sides. Batteries must be chassis mounted and also hidden from view.

[sally1800]

Here are the layouts for course design and the rules specific to this series.

Vehicle requirements for Top Truck Challenge event
- Top Truck rigs will be required to have a minimum of 20 scale points and no more then 40 will be given. Each scale point will be equal to .5 seconds off of the total time of the day.

Vehicle suggestions for Top Truck Challenge event
-Your vehicle will get wet and muddy, therefore it is highly suggested to be waterproof.
-It is suggested that the vehicle has a working winch, no buddy assistance will be allowed.
- This event will test the limits of the vehicles, therefore it is suggested to make the strongest vehicle possible.
- Mud is sticky, therefore it is suggested that wheel speed and torque be of high concern when preparing your vehicle.
-Be prepared to get wet, have fun, laugh and break some parts!

General scoring and course progress for Frame Twister, Rock Crawl and Tank Trap:
- Gates and boundaries if hit will be a 30 second penalty.
- If a course can not be completed the driver must call out to stop time, all gates left will be added to the time the vehicle was on course, 1 gate left is equal to a 1 minute time penalty.
-winching, rear steer, dig and reverses are all allowed and are not penalized.
-winching must be off a fixed object or a rig, no assistance is allowed during the winching progress, nor is anyone allowed to be touching the line or hook when winching.

EX: If 3 gates are left = 180 seconds (3 minutes) + the driver stopped time at 120 seconds (2 minutes) they would have a total time of 300 seconds for that course.

- If the course was completed, then no penalty will be issued for non completed gates and the final score will be the time on course (unless a gate or boundary was hit).

Out of bounds markers and Gates:
-Out of bounds markers (such as gates and rope line) will be used to show a course outline, in the event that one of these is hit a 30 second penalty will be given, this applies to the Frame Twister, Tank Trap and Rock Crawl only. If a rope line is tangled on a vehicle time can be stopped to untangle the line, the judge will therefore allow the vehicle to be picked up to untangle. The vehicle will then be replaced in a similar location on course by the judge. In the case of a gate a vehicle will have to be driven out of the obstacle and back to the course, time will not stop for any other reason then a tangled line. A gate may be straddled for progress of the course, but a 30 second penalty will be assessed.

General scoring and progress for Hill Climb, Mud Pit and Tractor Pull:
-When marking progress on course, 1 inch is equal to 2 seconds.
-When scored on the mud pit, hill climb and tractor pull distance will be measured from the end of the prescribed area and from the back of the farthest back tire from the end of the course.
- If a boundary marker is hit on the Mud Pit, Hill climb or Tractor Pull The vehicle will be stopped as will time.
-The time on course will added to the distance not traveled (measured by inches), the distance will be measured from the farthest back tire on the course to the finish line.
- If the course is completed time on course will be your score.
-winching is not allowed.
- Reversing is not allowed

EX: If the driver stops time after 5 seconds and there was 72 (144 seconds) inches left of the course their total would be 149 seconds for that course.

I dont think any of my scalers have a chance with that scoring system

[JAS82]

Bumpers (items must be chassis mounted and separate from the body)


What if my rear bumper is body mounted I cant run? Front is chassis mounted.

[S ARR T 8]

Mine will make it IM IN

Bumper can be part of the body. I just post this up to start a northern Top Truck thread

[sally1800]

This will be held at Busse wood , Date will be later announced.

p.s. Rule are not firm yet I just believe these are best fitting for this type of event. I want to post them and bounce it around.

[jetboat]

shirt wasnt me... your buddy Billygoat ordered that thru me from a friend that does shirts... he never paid me for it though. You just gave me the perfect chance to sell it. I would have been a fool not to take advantage


What I have never liked on the Nat scale rules... they tend to favor pickup trucks over other vehicles.

I could easily build a truck that would score the max points if I wanted... just a little brakeline and some silv solder.

I know he told me years ago that crappy old man.

As far as favoring I think there is advantage to long wheel base just as short.

Long will climb better where short does better on the rock. I had my Bronco all the way to 13.125 . But I have found I like 12.5

My new Jeep is a monster. but it not 13 in yet

Also lighter rig will do better on the rocks but hill climb and tank trap or puller

It more of pick your weapon and practice.

Chris has a cool as truck



I can't see this costing over $500 total RTR


As or the National rules I don't agree with every thing they did but. I will support there rules. It helps to make a base ground.

If there was none I would still be sneaking my 13 in wheel base on my comp rig for sure.

i dont think they will allow this at busse woods. mud pit, tank-trap,
hill climb, and we cant dig holes for the tank-trap and mud pit, or can we?

[S ARR T 8]

alot worse goes on in there trust me

[jetboat]

Im not sure I would want to be doing it in a public park.... thats just me.

Hard to find a place you can do everything in 1 spot. Might consider maybe doing a series where you do the rock crawl and hill climb at Busse and then mud pit,tanktrap and obsticle course on private property.

I personally luck out in that I have my "farm" where everything can be done in 1 spot.

True a public park for TTC can be a problem. How far is the farm from the city Jeff?

[scale-bronco]

we could maybe have it at my house, and thats a maybe. i would have to talk to my dad, meet the people that i havent already met. and then we would have to build a course.

Maybe start you own TTC

See I know these Wood like the back of my hand. I have been mountain bike hear for 20 year. I know spots hear at Busse that we will not even be seen. I would rather do every event at one location. If there is problems that I really just don't see then it can be moved. I do have a few trick up my sleeve.

I post this Northern TTC so the guy that are interest will start to prepare there rig's

[rookie01]

good luck

its about 2hrs from my house, no clue from the city.

[jetboat]

something I was thinking as i drove into the city this morning... Im not sure I would want to dig in Busse woods, you dont know what bodies you might find.

I don't think will even need to. I was looking for some picture I took two years back. Of a great water stream that I mountain bike threw. I just could not find them yet.

But if the spot I was thinking of first won't work this one for sure will. Shallow in spots. Kinda hairy in others. It off the beaten path. But just as easy to park and walk about as fair as it is to walk to the main dam.
