racing has introduced several entry level RC vehicles over the years.
These vehicles have allowed many newcomers to enter the hobby without
spending much money.
now offers low cost rock crawlers in the 1/8 scale and the 1/10 scale
range. Today we will look at the 1/10 scale Rockslide RS10 rock
though you might be lead to believe this is an entry level crawler, you
will find that it has some features for the seasoned crawler as well.
It's time to take a closer look at the Rockslide RS10.

first thing I noticed upon opening the box were the tires. They're not
replicas of full scale crawler tires but they look very cool.
inspection I found many aluminum and zinc alloy parts were used in the
construction of the RS10. The overall quality of the vehicle has
impressed me this far.
painted body is perfect for a rock crawler. The body you see does not
have any decals on it at all. Everything you see, including the grill,
lights, and logos are printed on the inside of the shell. You will not
have to worry about decals getting tore up from dings and scrapes.
did trim the body a little before test driving the RS10. I trimmed the
front of the body directly below the grill and the rear of the body
below the tail lights. Slightly trimming the front and rear corners
also helps with tire rub.
with the RS10 RTR are controller, 6-cell battery pack, charger, and
instructions. I would like to see some more in depth technical data on
the included electronics, but the instructions do include a decent
trouble shooting guide and an adequate how to section. The highlight of
the instruction booklet is its in depth parts list with detailed

of the great features of the RS10 are the axles. Both front and rear
axles are angled to allow more clearance for the center gear housing.
This is a great design that keeps the center of the axle from hanging
down lower than the steering knuckles. The less the rocks can grab a
hold of the better off we are. Good job!
you've probably noticed from the pictures, the RS10 is a "motors on
axles" rig. "MOA" for short. Not only do you get more power but this
also frees up the suspension some from the lack of drive shafts.
is beneficial in many ways. Not only is the weight from the motors on
the drive shafts, the battery and electronics can also be lower in the
chassis which creates a lower center of gravity. A very important
aspect in rock crawling.
of the axles contains plastic gears, except for the pinion gear of
coarse. The gears are supported with a full set of ball bearings.
Diff gear, or spool gear, is locked in place with two plastic plates
and four screws. Locked diffs is a set standard for rock crawlers. This
allows both left and right tires to equally grab as much traction as
dogbones are used to transfer the power to the wheel spindles. Each
wheel is seated on an aluminum hex and is held on with a standard self
locking M4 nut.
beadlock rim consists of a plastic center and two zinc alloy retainer
discs. The zinc alloy discs add weight to each wheel which helps with
traction. Each tire/wheel combo weighs 7.5oz. The tires are a
medium-soft compound with an aggressive tread.

transmitter uses a 27MHz FM frequency and includes features like
digital trim for all three channels, dual rates, and most impressive,

is easy to toggle through all four of the 4WS modes. Pressing a button
on the transmitter grip will toggle through the four different modes.
The first mode is front wheel steer only. The second mode is crab steer
(all wheels point in same direction) and the third mode is four wheel
steer (front and rear wheels turn in opposite directions). The fourth
and final mode is rear wheel steer. Pressing the button again will
cycle you back through the different modes.
included 4ch receiver is the LanSu LS-202-R. The receiver is perched on
top of the crawler's aluminum chassis and is held in place with double
sided servo tape.
steering servos are needed to steer this 4WS crawler. Each standard
size servo is mounted to an axle and their performance is expected from
a ready to run crawler. They have enough torque for bashers, but if you
plan on doing some serious crawling you might consider upgrading.

Beiji Guang 70T 380 sized motor is mounted to each of the RS10 axles.
The motors appear to be wired in parallel which should help with clod
stall. Clod stall is when one of the motors stalls and the other keeps
running. This could happen if either the front or rear wheels are in a
bind or just under a heavier load. It is common for the rear wheels to
stop spinning when making steep climbs with minimal throttle. Clod
stall was named after the most popular MOA truck of all time, the Clod
power to the motors is a fan cooled LanSu electronic speed controller.
This ESC is designed for rock crawlers and uses an electronic brake
system to hold the vehicle in place on inclines. The ESC specs below
were taken directly from the website.
included 7.2v 1500mAh NiMH battery fits nicely in the battery
compartment located in the base of the chassis. Having the weight of
the battery at the bottom of the chassis will help the crawlers ability
to climb and maneuver inclines with more stability.
battery is held in place by a u-shaped rod which pivots at one end and
is bent at the other to fit into two small holes at the bottom of the
chassis. This rod which is called the battery retainer clasp holds the
battery effectively, although it does tend to be a little difficult to
disengage at times.
wall charger is also included with the Rockslide but I recommend buying
a descent inexpensive peak charger for better control. The included
charger has an output rate of DC 7.2v with 500mA and is of course

four link suspension has loads of smooth articulation thanks to the

It's an old rock crawler course that is rarely used anymore. Perfect!
I could go have fun I need to charge the battery. I used my dynamite

see the progress of the charge. The included wall charger does charge

set the RS10 at the foot of the first obstacle and applied a little
throttle. The throttle is smooth and the truck has a good throttle
the front wheels were on the large boulder, I tried to creep up and
over but the crawler went head over heels. The approach I needed to
take required a bit more momentum. I crawled the front wheels onto the
boulder, I goosed it, and the truck hopped onto the rock. Sweet!
didn't take long for me to get accustomed to how the RS10 likes to be
driven. Some obstacles needed to be crept over and others required some
testosterone. I was having a blast!
stock tires are a little stiff, but I was amazed at some of the stuff I
could get over. I can see that I'll be doing some work on them soon.
Cutting the treads in half will allow the tires to flex and fold a
little more. Scoring an X-shaped pattern into the back side of the tire
with a small grinding stone attached to a dremell will also add some
more flexibility. You must be VERY careful not to go too deep or you
will ruin the tire. The easiest option would just be spending $20-$30
on some new meats.
four wheel steering saved me from many spills. It doesn't take long to
remember the mode sequence. Before long I was beeping through them
most RTR crawlers, the steering servos don't have enough torque to turn
the tires while in a bind. Even though this probably saves on broken
parts, if I decide to enter any competitions I'll invest in a couple of
servos, but for playing around and having fun, these will do just fine.
stall was mentioned earlier in this review and I did notice some at low
speeds. While crawling up steep inclines the rear wheels would stop
spinning. This troubled me at first, but then I found I could use it to
my advantage. Don't get me wrong, I can get all tires to spin by
applying more throttle, but when going up steep inclines I would get a
good look at the underside of the vehicle. I prefer looking at the top
much better! I found that if you allowed the clod stall to happen it
was advantageous to getting up the obstacle. The front tires would pull
more than the rear and lessen the chances of flipping backward. Works
last thing I need to mention is how well all four tires stay planted on
the ground. When a rock crawler has as much articulation as the RS10,
it's easy to get twisted on the rocks. I was surprised at how little
that actually happened. There were some instances where the suspension
got itself into a bind, but 90% of the time, all four tires hooked up.
This could be do to the lack of torque twist caused by drive shafts.
must say I was excited taking the RS10 out for testing, but I was very
surprised at how well it crawled for a stock RTR. The RedCat Rockslide
RS10 performed very well and held up great to abuse.
can sum up my experience with the Rockslide RS10 with three words. Fun,
fun, and fun. This crawler has good quality and it costs less than
$200. I give the RS10 an A++ for value!
was able to get around six hours of crawling in with the RS10 and not
only did nothing break, I had an enjoyable yet surprisingly relaxing
time. There's something about conquering that obstacle that gives me a
sense of accomplishment. I also can't deny that I just like running
