U4RC Rock Racing Series info and update thread.
 

We will be using this thread as an ongoing info thread for the U4RC Rock Racing Series. For the latest info always check the last posts in this thread. Also be sure to check out and like our facebook page at Ultimate4rc.com for additional info.

U4RC started in 2010 with the King of the Compound races in Apple valley. In April of this year we were offered the opportunity to create a permanent track at Glen Helen R/C Raceway in Devore. Since then we have run three races, 2 at Glean Helen, and one that the KOTC track. During that time we have discussed, and have come up with a set of classes and some basic rules that we feel fit our series pretty good, based on the experience from the first races. These rules are open for discussion among anyone that has input, and in fact we welcome that input.

Re: U4RC Rock Racing Series info and update thread.
 

you stated this is not a "foot" race so will all of the drives be in a drivers stand? I feel that by doing that if that is the case you will end up having a hard time creating new tracks or locations
just my .02

Re: U4RC Rock Racing Series info and update thread.
 

What about the TH? 1.9 but with IFS and plastic tub?

Re: U4RC Rock Racing Series info and update thread.
 

Looks to me the TH falls under 1.9 Competitor class.

Re: U4RC Rock Racing Series info and update thread.
 

Not necessarily, there are other locations that will have a "drivers area" Glen Helen does have an actual drivers stand.

We will also have "endurance" type races that is why we put "as much as possible."

Re: U4RC Rock Racing Series info and update thread.
 

Great input and questions guys!

K.Hess; Great points, thanks for the topic.
You are right it is difficult to design a course where you don't have to chase your rig. The "not a foot race" statement is pertaining to the fact that we want to see the best "driver/rig" combination win the race. Not just the driver that is most physically fit/capable win the race just because he/she can chase a car around faster. In our eyes that doesn't prove the best "r/c rig" just the most fit driver participating in the race.

We have already had drivers show up to race that are wheelchair bound. We would like to allow those drivers a fair chance at a win also. Of course not all venues are going to be condusive to this. Some of the endurance races definitley will require drivers to follow thier rigs more.

Course design is critical in avoiding "chasing rigs" as much as possible. I have another write-up that addresses "Course Design" that I will postup when I get the opportunity. It contains lots of helpful tips that may help others set up tracks. And may answer several questions that people have.

Re: U4RC Rock Racing Series info and update thread.
 

The classes sound great ...it will be fun to see the lap times of each class.

How will scoring be done? Will it be similar to normal racing with a sensor And tracking device?

Re: U4RC Rock Racing Series info and update thread.
 

This will depend on the location and race type. We do have access to a timing system. The first races have all been scored manually without any major issues. We are actively headed toward having timing set up whenever possible.

Re: U4RC Rock Racing Series info and update thread.
 

I also have another location to build a track.

Re: U4RC Rock Racing Series info and update thread.
 

All I need to do is get a 35T motor and I'm out there. Glenn Helen would be closest to me. When's the next race?

Re: U4RC Rock Racing Series info and update thread.
 

We had originally scheduled the race for the 27th of this month, not realizing there were 2 conflicting events. The Lucas Oil 1:1 Series is in town the same weekend, and also the WCRCC awards banquet is that day. Clogged 2 lane road, and stepping on another local series was not something we wanted to do.

It is looking like July 20th at 10 am at this point to get our monthly race in. 8)

Re: U4RC Rock Racing Series info and update thread.
 

I might be able to make that one. If not, I'll be at the next one.

Re: U4RC Rock Racing Series info and update thread.
 

Hope both my rigs are ready by the 20th.

The 20th works out better for me anyway. See ya then

Re: U4RC Rock Racing Series info and update thread.
 

Well crap I got the day wrong. Can you guys do Sunday the 21st?

Re: U4RC Rock Racing Series info and update thread.
 

Whoa.... Brian is having a lil' brain fart, ;-)LOL!

The race is on Sunday the 21st(my house is hosting a family event 20th that is a "no-miss" event).
Sorry for the inconvenience guys and gals.

Re: U4RC Rock Racing Series info and update thread.
 

I might throw in my 13.5 set-up from my SC10 so I can have some speed. No brakes, but lots of speed.:shock:

Re: U4RC Rock Racing Series info and update thread.
 

thanks for the consideration

Re: U4RC Rock Racing Series info and update thread.
 

See you guys there.

Can't wait!!!

Re: U4RC Rock Racing Series info and update thread.
 

Is everyone ok with the rules the way they are? Is there anything that is confusing or needs attention?

Just having a hard time believing we got it right the first time. :ror:

In my opinion maybe there should be a stock competitor class for stock twin hammer time vehicles. Thoughts!

Re: U4RC Rock Racing Series info and update thread.
 

In the 3 races we have had so far I am only aware of 2 "box stock" rigs competing. One in 1.9, and one in 2.2. Both times these rigs have done pretty good running against all out modified rigs.

One problem with a box stock or as we call it a "spec" class is, where do you draw the line on what is "stock"? If you change tires it is no longer stock, but that could be an advantage or a disadvantage depending on the tire chosen.

Another problem is having enough box stock rigs to fill a class. Personally, I'd rather say "I beat 4 guys with modded rigs, with my box stock rig," then race against only one or two guys, if even that, in a spec class.

We would need a minimum of 4 rigs to create another class of any type. We have been asked to start a Powder Puff class, same deal, if it happens we will do what the drivers want. "thumbsup"

Ok cool. As long as I know I have a fighting chance against the mod trucks then I'm in.

Re: U4RC Rock Racing Series info and update thread.
 

A drivers skill is way more important as it usually is. Round 1 I ran against Scott Hughes. He not only beat my HIGHLY modded TH with his stock (minus a 20t motor and the small Proline 1.9 swampers), he lapped me in the heat and in the main. If you are reading this Scott, don't expect that to happen again. :twisted:

Re: U4RC Rock Racing Series info and update thread.
 

What about 1.9 tires on 2.2 wheels?

Re: U4RC Rock Racing Series info and update thread.
 

For 2.2 or 1.9 class?

We talked about allowing rigs to move up in class but not down, time and participation allowing. IE: a 1.9 trail rig in both 1.9 trail and 1.9 comp in an effort to give drivers the option of more racing without having rigs for more than one class. If we happen to get twice the crowd, then this would not be an option. Anyone have opinions on that idea?

The exception would be Trophy 2.2, that will be a stand alone class. You either meet the specs for that class or not.

Re: U4RC Rock Racing Series info and update thread.
 

1.9 class. What differance does it make on the wheel diameter? Is what I am getting at. Classes should be set by tire diameter not wheel size. 1.9 tires now are as big as some 2.2.

Re: U4RC Rock Racing Series info and update thread.
 

Well this sucks!! My exo with 2.2 wheels and tires won't make the rules. Shit even with SC wheels and tires it barely makes the 12.5 and even the 1.9's on it, its at 13'' We'll that was fun while it lasted :cry: I guess it goes back on the shelf.

Re: U4RC Rock Racing Series info and update thread.
 

Our thought was to keep the rigs looking as scale as possible in all classes without writing 100 page rule book. I am not aware of any Ultra 4 1:1 rigs running 22" wheels.


Easy Mike this is a discussion thread, nothing is etched in stone. "thumbsup" Can you please post a pic of your rig with the 2.2's and give us the exact width? No wideners right?

Re: U4RC Rock Racing Series info and update thread.
 

So "technically" there should be no 2.2 class at all.

Bry, I will try to get a pick, but I'm leaving on a camping trip for this weekend so it might have to happen after I get back. BUT....if you guys are going to let it run I need to know asap, because I'm going to stop working on it right now if it can't run. My 1.9s are right at 13'' and I know the 2.2 are going to be a tad wider.

Re: U4RC Rock Racing Series info and update thread.
 

Thanks for the questions and input. RPD nailed it pretty good. We wrote the class specs that way for uniformity and simplicity reasons. I know in some forms of full size off road racing, classes may be seperated by tire diameter. But for the most part the r/c world is divided by rim diameter. So we decided to stick with that uniformity.

Rules can always be amended, and if we see fit in the future we may seperate classes differently.

Mike, the reason we left the SCT rim allowance in the 2.2 Comp class was for rigs just like the EXO that come stock with SCT rims. The realism is kinda out the door the with different diameters of faces on SCT rims.

The EXO would be unproportionally wide with most standard 2.2 rims. So we allowed SCT rims for the 2.2 Competitor class. Like Brian said, post up some info and we will definitley address the width rule if possible.

Thanks for the input to the thread, you may be asking questions that are also helpful to others.

Re: U4RC Rock Racing Series info and update thread.
 

In my opinion....those rules/classes sound reasonable/compettitive, and as with real racing while trying to conform to the rules try to exploit them....meaning find the tallest tire manufactured in the class to exploit that rule...or buy a 4-pole motor instead of a 2 or 3 pole for more torque. Stay within the rules just figure out the best tire, motor, esc, servo, whatever is required to win...

Seems like the new system is the Wrexo....:evil:

Because if you start to win races cuz you have brushless, instead of brushed....(my case...), or whatever the case may be, then you can "cheat" within the rules and bring home trophies!

Good Luck!

See you on the 21st with the new setup...."thumbsup"

Re: U4RC Rock Racing Series info and update thread.
 

The rules are fine and will evolve as this new sport grows, changes will be needed, who can figure it all out and make everything or everybody happy at once. People will complain and bitch no matter what, even if they haven't tried it yet, and that's just there negative bs personality.

Re: U4RC Rock Racing Series info and update thread.
 

Nobody will be turned away as long as it is not a "track" car, like a 4wd sc truck. This is scale desert rock racing. :)

Re: U4RC Rock Racing Series info and update thread.
 

here's the 1.9's on it and its 13'' wide, you have to admit that the last 2 shots look scale and bad ass:mrgreen:
