NEW RULES!!!!!!!!!!! As of 11/1/13

U4RC’s main focus is to provide hobbyists an avenue to race r/c vehicles in as similar and “scale” fashion as possible to full size rock racing. There can be both, endurance themed and short course style tracks designed. It is the intention of U4RC to showcase the r/c rig’s capabilities, not the physical condition of the driver, as much as possible. Meaning that, “these are r/c car races, not human foot races”. Courses will be designed with the intent of “equal chance for all”, as much as possible. It has to look like something you would see on a 1:1 trail, race, or street rig.

All Classes:

MOA are not allowed. Non-scale race-track style vehicles are not allowed. Battery must be chassis mounted, and hidden in a scale fashion. Electric powered vehicles only. No Comp, short course, cut n shut, or pin tires allowed. A tire for the U4RC must be a scale tire, either a licensed replica, or a non-licensed replica. Rigs not meeting specific class specs will be placed in the fairest class possible at the judge’s discretion.

1.9 Trail:

This class is for 1.9” tire clad vehicles that are box stock thru highly modified. Vehicle must be scale in appearance. Rim diameter must not exceed 1.9”at any point. No short course style rims allowed. Vehicles must have (2) solid axles. Vehicles must have rail style, tube, or twin vertical plate chassis. This class requires the rig to have a scale body like your typical 1.9 “scale”rig or TUFF Truck. Wheelbase must not exceed 13” and track width must not exceed 10”.

1.9 Competitor:

This class is for 1.9” tire clad rigs that are highly modified and resemble full size race vehicles. Vehicle must be scale in appearance for rock-race style racing. This class includes rigs running plastic chassis and/or roll cages. Open to any shaft driven, non-moa axle configuration. Single or double solid axle or independent suspension is allowed. Rim diameter must not exceed 1.9” at any point. Short course style rims are not allowed. Rail style, tub style and tube chassis’ are allowed. Wheelbase must not exceed 13” and track width must not exceed 11”. Rear steering is allowed.

2.2 Competitor:

This class is for 2.2” tire clad vehicles that are box stock thru highly modified. Vehicle must be scale in appearance for rock-race style racing. This class includes rigs running plastic chassis and/or roll cages. Open to any shaft driven, non-moa axle configuration. Single or double solid axle or independent suspension is allowed. Short course style rims are allowed. No Comp, short course, or pin tires allowed. A tire for this class must be a scale tire, either a licensed replica, or a non-licensed replica. It has to look like something you would see on a 1:1 trail, race, or street rig. Wheelbase must not exceed 14.5” and track width must not exceed 13”. Rear steering is allowed.

Trophy 2.2:

This is a builder’s class. This class is for 2.2” tire clad Ultra4 style rigs that are highly modified and highly resemble full size rock race vehicles. This class only includes rigs running full metal roll cages or, a metal upper cage attached to a factory skid plate. Meaning no plastic chassis component allowed except skid plate. You can use a factory skid plate, such as a Wraith, or Wreckluse skid. You could also use the metal portion of an Exo Skid, but not any plastic pieces attached to it. Vehicle must be very scale in appearance. Open to shaft driven, non-moa axle configurations. Single or double solid axle and non-factory independent suspensions (aka hand fab) are allowed. Rim diameter must not exceed 2.2” at any point. Short course style rims are not allowed. Rail style and tube style chassis’ are allowed. Minimum overall chassis height, we are currently researching what this should be, but we came up with 4.5”. Wheelbase must not exceed 14.5” and track width must not exceed 12.5”. Rear steering is allowed. Minimum vehicle weight 8lbs. Cockpit area must have a driver. (Either Lexan driver insert or actual figurine). Since our emphasis is on scale vehicles, terrain, and media, we are going to be strict about this driver requirement in 2.2 Trophy. The biggest change for this series is the helmet requirement and the fact that this will be enforced.

I'll have to try and make it down one day for some U4RC action.

Do I need a front locker, or can I carry some speed over and around the course? I still run mine with a diff.

[Steve13]

I would lock it for your vaterra?

[Steve13]

For what it's worth, I run my TH unlocked with 500,000 wt in the diff at Glen Helen. Our track has some real tight turns so steering is critical.

Thanks Brian. That's what I figured. I think if it was a "slow crawl style event" I would change it out for sure.
