The one track that isn't garnering much attention at the moment and one I hope to change is the Ultra 4 track. Luke Magdy, president of BFRC authorized the construction and implementation of this class at the park and currently there is the base bone structure of the track in place. Needed is someone to run it. There is no shortage of Wraith and Yeti type trucks in Calgary... they number in the hundreds. It's a very popular RC truck for sure. We just need to get this one rolling. For those interested... I have pulled from both U4RC.com and Axial.com websites the following. Have a read and then go the the Blackfoot RC page on Facebook to follow along or contribute.

What is Rock Racing?
By Axial on May 27, 2015
Axial offers vehicles identified as rock crawlers
and as rock racers such as the SCX10 and the Yeti, respectively. To make the
perfect selection when purchasing your R/C vehicle, you need to know the
difference between rock crawling and rock racing.
Rock crawling has been around as long as there have
been off-road vehicles like the classic Jeep and rocks to drive them on. The
Rubicon Trail in northern California might have originally been used by
settlers in covered wagons, but the rocks on that trail have probably seen more
rubber tires than wagon wheels. When people think of rock crawling, they often
think of this iconic trail or a similar scene and driving over rock formations
with beautiful vistas. They see rock crawling as slow, enjoyable and relaxing.
They also recognize that it’s challenging. This is recreational rock crawling.
It can be a pretty tame trip down an easy trail with a few rocks to negotiate
or a hardcore excursion with ample body damage and winching. Recreational rock
crawling led to the creation of competitive rock crawling. You probably already
know that if it is automotive in nature, it can and will be made into a
competition.
Rock crawling, as the name implies, generally takes
place on rocky terrain and is not about going fast, but sometimes the skinny
pedal is the only way to get up and over something. Not all rock crawling is
competitive, of course, but when it is a competition, time is a factor and,
thus, speed is a factor. Hence, you’ll see plenty of throttle used at rock
crawling competitions. The course is most often marked with such items such as
cones, tape or rope. Hitting markers results in penalties. So, competitive
crawling requires a mix of speed and finesse. You won’t win if you finish with
the fastest time, but hit every marker on the course and racked up the time
penalties. Conversely, you won’t win a rock crawling competition if you miss
every marker with a perfectly executed and clean run, but take all day to
finish the course. As described previously, rock crawling is also a popular
recreational motorsport. In this case, rock crawling is often called trail
riding. Again, as long as the first Jeeps were available to the public, this
type of rock crawling has existed.
In the same way that just about anything automotive
can be made into a competition, any automotive competition can increase in
intensity if given a little time. Thus rock crawling has given us rock racing.
Rock racing comes in many forms. The first type of rock racing evolved from
rock crawling competitions that focused more on speed and less on the finesse
needed to avoid markers and the accompanying penalties. Some rock racing
competitions feature side-by-side racing by running two vehicles on the course at
once. One of the more popular forms of rock racing came from a challenge made
between desert racers and rock crawlers. The challenge became an annual event
called the King of the Hammers. This race combined high speed desert racing and
grueling rock crawling. Both forms of racing have high attrition rates and
require specialized equipment.
Besides the increased speeds, one of the biggest
differences between rock crawling and rock racing is that most rock racing has
the whole field on course at once. Again, some small course rock racing might
feature two vehicles that are running partially separated courses, but Ultra4
style racing such as the King of the Hammers has the whole field racing at
once. This creates an interesting element as isn’t always easy to pass a
competitor who’s stuck on the rocks you also need to get up and over.
R/C rock racing is mostly patterned after the
growing full-size Ultra4 style of racing. While people are R/C rock racing all
around the country and world, one organization has stood out as a leading in
developing a race format, rules and in promoting events. That racing body is
U4RC. Following is an interview that helps explain what rock racing
and U4RC are all about.
The R/C community is starting to hear more and
more about U4RC, but who is behind this still relatively new
organization? U4RC is; Jerry Tobin
(owner/founder), Brian Jones (owner/co-founder) and Jerry Ellifritz
(owner/promoter). Between the three owners of U4RC there is a very solid
background in R/C. Jerry Tobin has been in the SoCal R/C crawling scene since
2005. Jerry competed in competitive R/C crawling at a national level for several
seasons and was ranked in the top 15 for USRCCA Super class. In 2009, Tobin
created the infamous “King of the Compound” R/C endurance rock/desert race
which U4RC, as we know it today, was born from. Brian Jones was around when R/C
rock crawling was in its infancy and still on the pages of the monster truck
forums, which RCCrawler.com stemmed from originally. Brian has been highly
involved over the years in many aspects of growth in the crawling segment of
R/C, including exhibitions, trade shows and was one of the original owners of
RCP Crawlers. Brian too, was a national level ranked competitive crawler. He
even attended the first USRCCA Nationals event in Moab, Utah. Jerry Ellifritz
has been involved in R/C crawling for about five years, and comes from the
scale side of the hobby originally. In those five years, Jerry has immersed
himself deeply in R/C crawling including coordinating “G6” scale events,
several one-off scale events and, of course, U4RC. Jerry’s involvement with U4
has proven to be invaluable to the advancement of this exciting, new segment of
R/C.
Tell us about U4RC? What is its mission? Who
is it geared towards? U4RC is an R/C rock
racing organization that was launched in 2012. Our mission is to deliver R/C
racing with a real, grass roots operating style and feel to it, unlike what is
mostly available to the “go fast” R/C community. Currently the majority of the
racers are from the R/C crawling world, although we are surprised constantly by
the influx of inquiries and new racers from the “go fast” community. We feel
U4RC is a great “crossover” of several genres, mainly because “racers” as well
as “scalers” can find common ground within the classes available through U4RC.
The class structure is set up so that everyone from a “newbie” with a box stock
RTR rig, (SCX10, Spawn, Yeti, Wraith) all the way to advanced custom tuber
chassis “builders/racers” have a competitive, fun class to run in.
How many tracks are affiliated with U4RC and
what are they typically like? The list of tracks is
growing quickly throughout the nation and globally, with tracks in SoCal,
NorCal, Washington, Arizona, Florida, Minnesota and so forth. There are
currently at least a dozen dedicated U4RC tracks at R/C facilities nationally.
There are also U4RC tracks and clubs globally, including Canada, Australia,
Austria, South America, Italy, Poland and so on (too many places to list).
Given that U4RC is modeled after full-size rock
racing, tracks are typically a design that is different from what is considered
the “norm” in R/C off-road racing. U4 tracks are not generally groomed (with
the exception of watering), there is no sticky stuff, and you will never see a
broom used on a U4 track. In contrast, our tracks usually include one or two
rock gardens, a hill climb obstacle, elevation changes, jumps, whoops, wide
open straights, stutter jumps, semi-tight technical sections, moguls,
sand/gravel pits, etc.
What is the U4RC race format? U4RC
runs a heads up heat, LCQ (Last Chance Qualifier), Main style racing format,
where top finishing positions are key in every “Heat” round for advancement to
the “Main” races. We feel this format is the purest way to find the best of the
best for the day. Many forms of R/C racing run a “quickest time” advancement
structure during lower rounds. Not at U4RC, we want to avoid drivers having an
opportunity to sandbag early in the day by just getting a good “hot lap” time
in and not conserving the rig because the track itself is a challenge along
with the fellow racers you’re up against.
U4RC, like the full-size competition it
models, combines go-fast racing and extreme rock crawling. Who usually does
better, the racer types or the rock crawlers? That
is a difficult question to accurately answer due to the varying terrains on the
different U4RC tracks. The racer types definitely excel on the faster, less
technical tracks where high speed vehicle control is key. The crawlers that
learn to “go fast” well tend to be very successful due to the fact that you
have to conserve your rig to a certain extent during the course of a U4 race.
Overall the fastest racers to date in U4RC are the rock crawling crowd, which
is very similar scenario when compared to our full size counterparts. Once the
racer types learn to conserve their rigs, look out!
What classes are there in U4RC? Describe how
the Axial Yeti, Wraith and SCX10 typically fit in the various classes? There
are six classes in U4RC racing currently. There is a class available for every
Axial rig made at this point. The classes are 1.9 Trail, 1.9 Comp, 1.9 Trophy,
2.2 Comp (Limited), 2.2 Comp (Open) and 2.2 Trophy. The SCX10 platform falls
into the 1.9 Trail class, which is intended for trail rigs such as (but not
limited to) a “G6” or “1.9 Deadbolt” or “Falken” SCX10. For Wraith owners,
there is 2.2 Comp (limited), which is limited to a Solid/Solid axle
configuration. The Wraith “Spawn” rock racer is a great starting point for this
class. All Wraith models are legal for this class in their stock configuration.
Axial Yeti owners have a place to race in 2.2 Comp (Open), which is open to the
IFS/Solid axle configuration of the Yeti. The Yetis have proven to totally
dominate 2.2 Comp Open since its release last year. Not to be forgotten is the
fact that the majority of the 1.9 and 2.2 Trophy class rigs are either built
using the SCX10 (1.9) and Wraiths (2.2) as their base for the builds.
Is there a class for the Axial Yeti
XL? We are currently writing rules for the
next series that will include a class for the Axial Yeti XL. The XL hit the
market just after the current rules were released last year. Given the success
and performance of the RTR version and the recently released kit version, we
definitely will provide a place for XL Yeti owners to compete. U4RC track in
the future will be designed with consideration of the Yeti XL.
What goes into a good U4RC vehicle? Probably
the most important thing would be choosing the right components. U4RC racing is
hard on parts so choosing the right upgrades for your application is a must.
In an entry-level class where your car is close to stock, the smart thing
would be to upgrade the smaller parts before, say, throwing a 3S pack and a
4000+ Kv motor in it. Those things are more suited for the fully built
rigs of the mod and trophy classes. Another very important aspect of
setting up a car is suspension. Good shocks, springs and the right oil
combo makes a huge difference. Since we race at different tracks, with
varying technical levels and obstacles, that means the driver needs to be on
top of their set-up at all times. Of course, as in all racing, tires are also a
big deal. Some drivers actually sipe their own tires for different tracks, just
as in the 1:1 world. Fortunately, we have recently had companies
designing not only tires, but many other parts specifically for U4RC racing and
the results have been outstanding. If you take a look at our sponsor list you
will see what I mean.
There’s an old saying in racing that to finish
first you must first finish. That seems to have been suited for Ultra4 racing.
Do you have any driving advice you can share for U4RC racers? You
nailed it 100% with that statement. That old adage couldn’t apply any more that
to U4RC racing. A conservative driving style will get your rig to the finish
line, because you are racing against other drivers as well as the challenging
terrain. The racers that have a “wide open” driving style generally run a
higher risk of catastrophic equipment failures. This is due to the nature of U4
racing and the built-in obstacles throughout the track. Don’t expect the “turn
marshal” to win the race for you. Keeping the rubber side down is the way to
go. Walk the track prior to your race and identify any obstacles that you will
want to avoid or gather your game plan for tackling those obstacles. Final bit
of advice is to drive. Get out, drive your rig and learn how it reacts to your
inputs from the transmitter.
What do you see in the future for U4RC? We
believe that U4RC will bridge the gap between the R/C rock crawling community
and the R/C racer community. With the amount of scale realism required from the
rules and the extremely fast paced action on the track, it has aspects that
both sides will be drawn to. U4RC is holding our first regional level event
here on the West Coast this June that is sure to see attendance of U4 racers
from all our neighboring states. There has also been overwhelming support and
interest from many of the top manufactures in the R/C world, which leads us to
believe our future looks bright.

ABOUT
Welcome to
U4RC.com, your source for anything and all things Radio Controlled Rock Racing!
The U4RC
concept is edge of control short course R/C on steroids. This is not groomed
tracks and traction compound! A U4RC track combines not only the toughest
desert sections, but big technical rocks, silt washes, the steepest hill climbs
and of course terrifying descents. U4RC is heads up heat racing against your
friends and family. Timed/scored heats let you know how you rate against the
competition every day, and with competitors around the world. U4RC is taking
your track experience to the next level of adrenaline.
U4RC’s main focus is to provide hobbyists an avenue
to race RC vehicles in as similar and “scale” fashion as possible to the 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 RC rig’s
capabilities, not the physical condition of the driver, as much as possible.
These are RC car races, not human foot races. Courses will be designed
with the intent of equal chance for all. It has to look like something you
would see on a 1:1 trail, race, or street rig. We are looking to add tracks
worldwide to be sanctioned, meaning you are willing to run our rules and
classes for series scores. Tracks need to have a fast section, tight turns,
changes in elevation, and technical rock sections. We don’t want drivers just
to be able to come out and go fast. If you ever been to an Ultra4 race you will
see there are fast sections and some very slow sections. For example: Bechard
RC Raceway is about 600yds running length and it takes roughly 80 seconds to
complete one lap.
RULES
U4RC rock racing is edge of control racing
that is sure to get your adrenaline pumping. It pits everything from
stock RTR 4 wheel drive vehicles, to full on custom rock racing and trail
rigs, against some of the toughest obstacles R/C cars have ever seen. A
U4RC track combines not only the toughest desert sections, but big technical
rocks, silt/sand washes, the steepest hill climbs and of course terrifying
descents. U4RC is heads up heat racing against your friends and family.
Timed/scored heats let you know how you rate against the competition every day,
and with competitors around the world. U4RC tracks can and do vary in
layout and terrain. In fact a U4RC track can be created almost anywhere
there is open space and dirt, often utilizing existing terrain features as
obstacles. On the other end of the spectrum is the permenant track.
Permenant U4RC tracks are being built and raced on literally all over the
world. So whether you are a single person looking for a track, or you are
part of a group looking to start your own U4RC series, this is the place to get
started. Below are the U4RC official rules/vehicle specs. You can expect
to see these rules being run as written at major U4RC events. Theses
rules, or local versions thereof, can be used by all groups that are part
of the U4RC family. Get out there, have fun and see what U4RC rack racing
is all about.
