Today's RC market offers several different solid axle
monster trucks to choose from but Redcat Racing wanted to be different.
A combination of solid axle four link suspension, realistic aluminum
frame, aluminum threaded shocks, 540 electric motor, scale appearance,
four wheel drive, four wheel steering, and a completely ready to run
package makes the Redcat Racing 1/10 scale Ground Pounder monster truck
a first of it's kind.
Name: Ground Pounder Scale: 1/10 Price: $299.99 (varies with dealer) Length: 18" Width: 13.25" Wheelbase: 12.5" Height (overall): 10.25" Motor: Brushed 540 motor Drive Train: 4WD shaft driven, solid axle with front
and rear sealed differentials. Included Battery: 7.2v 6cell battery pack with
charger Radio equipment: (Included) 3ch FM digital radio, 4
channel FM receiver, and two standard servos.

Sudden Impact Racing has entered into a partnership with Redcat Racing and will be adding the Ground Pounder to their arsenal of monster trucks. This addition is supposed to happen within the first quarter of 2010. Sudden Impact Racing and Redcat Racing are both very excited about this opportunity. You will now be able to buy the Redcat Racing Ground Pounder monster truck on the Sudden Impact Racing online store as well.
The Ground Pounder was developed, prototyped, and tested by Crawford Performance Engineering. You can see as soon as you look at the truck that this is not your average 1/10 scale ready to run monster truck.
The Redcat Racing Ground Pounder is unlike any other
1/10 scale RTR monster truck I'd ever seen. From the hulkish man
dominating most of the body surface to the flashy lettering, the body
screams monster truck. The post holes are drilled, the wheel wells are
trimmed, and the decals are applied.
The chassis is modeled after a tube frame from a full
size monster truck. It is made of two 6061 aluminum plates that are
anodized in blue. These two sides are joined by eight anodized threaded
The quality and build of parts looks great. There are
many aluminum parts used throughout the truck and we'll take a closer
look at some of those parts later.
The Redcat Racing Ground Pounder is truly an impressive
Also included in this ready to run package are a
transmitter, an instruction manual, an ESC instruction sheet, a
t-wrench, a Ni-MH battery pack, and a battery charger.

Wheels, tires, and drive train
The aggressive monster truck tires are glued to attractive
chrome plated plastic rims. The rims are designed after a full scale
monster truck's. Foam inserts are not used in the tires which allows
them to conform to the terrain, however it may also allow the tire to
collapse too easily.
The rims ride on a standard threaded spindle and are fastened
with 7mm lock nuts. The drive train is completely supported by a full
set of ball bearings.
The front and rear axles capture the sealed differentials.
Inside the differentials you will see metal spider gears which give
some resistance when turned by hand. Experience has shown that as the
gears wear some, they will spin more freely. It's good practice with
any new RC vehicle to change the diff lube after the first fifteen
hours of use or after the diffs loosen up. New gears have a tendency to
shed tiny metal shavings as they get seated properly. Changing the lube
removes those tiny shavings for a long lasting and smooth running diff.
Red grease is used to lube these diffs and can be replaced with diff
Metal dog bones are used inside the axle housings to transfer
power from the differentials to the wheel spindles. The only
angled movement the dogbones will see is from steering the vehicle. The
suspension plays no role in the angle of the dogbones since they are
encased in a solid axle. The dogbones should work just fine for this
Distributing power equally to the front and rear axles
is an easily removable center transfer case. The transfer case is very
simple and contains two plastic gears. These gears spin freely thanks
to sealed ball bearings. Red grease is used to lubricate these gears as
Mounted to the input shaft of the transfer case is a
slipper clutch which sports a plastic spur gear. The pads of the
slipper clutch are an abrasive material with metal clutch plates
squeezed against them. The pad material is new to me but the clutch
design is standard. Holding all of this together are a spring and
adjustable lock nut.
Spanning the gap between the transfer case and both
axles are two telescoping plastic drive shafts that include universal
joints at both ends. This was a good choice for this application
because of the angles the suspension will cause the drive shafts to

The included LanSu 3TD digital 27MHz FM transmitter is
loaded with cool features. Some of those features include 10 model
memory, dual rates, end point adjustments, servo reversing, and four
different steering settings.
To change the steering settings, press the lower button
on the handle. This is easy to do with the middle finger of the left
hand. Below are the four different settings listed in numerical order.
1. Front wheels steer and rear wheels are stationary.
2. Front and rear wheels steer in the same direction. Vehicle will
shift to the side while still facing forward. This is called crab
3. Front and rear wheels steer in the opposite direction. Vehicle will
4. Front wheels remain stationary and the rear wheels steer.
A LanSu electronics 4-channel LS-202-R FM receiver is
mounted with double sided foam tape.
The front and rear steering uses standard size B7018
9kgs servos for a total of two servos. Servo savers are not used on the
Ground Pounder. We will have to see how the servos hold up after some
Motor , clutch, and battery
Powering the Ground Pounder is a 540 electric motor with
banana plugs connecting the motor to the electronic speed controller.
There are no markings or decals on the ESC so I can't tell what brand
it is. Regardless of the brand, it works well and omits a "do, re, me"
tone when turned on to signify that it has found neutral. This is done
automatically so there is nothing you need to set on the ESC. The
specifications of the ESC are listed below.
Input: 6V-8.4V DC
BEC: 5V 1A
Current drain: 20A (forward), Max(spark): 300A, Reverse(spark): 150A
Application: 540/20T motor and above
Dimensions: 35mm(L) X 33mm(W) X 30mm(H)
A 6-cell 7.2V Ni-MH SC2100mAh battery pack and charger
are also included with the Redcat Racing Ground Pounder 1/10 scale
Rear of motor
The front and rear solid axles on the Ground Pounder are each
suspended by four aluminum adjustable links. This is where the term
"four link suspension" comes from. This setup allows the axles to
travel straight up and down, as well as articulate. The upper
links can be mounted in three different holes in the frame and the
lower links have two mounting options. This allows you to tweak the
geometry of the suspension.
Crushing cars is hard work. To cushion the blows, the Ground
Pounder is equipped with four threaded aluminum bodied oil filled
shocks. The blue finish looks great and really makes them stand out.
The threaded preload collars were screwed down which made the
suspension extremely stiff. I prefer a softer feel so I loosened all
the shock preload collars. The truck doesn't sit as high but at least
the suspension dampens more like it should now. If you would like to
change the ride height you can choose one of five different mounting
holes for the shocks. The lower the hole, the higher the truck will
sit. I left mine in the original hole for the look and feel of a real
The only other thing requiring some attention is the mounting
of the shocks. They are tight against the frame which makes it
difficult to adjust the threaded preload collars. I simply installed
one shim per shock where it meets the chassis. Problem solved. RedCat
Racing said they would be taking care of this at the factory on future
runs. I happened to get a truck from one of the first production runs.
This truck is very new!
The shocks on this thing are sweet. They are not at all
what I would expect from a 1/10 scale RTR truck in this price range.
The large oil filled aluminum threaded bodies are more like what you
would find on 1/8 scale vehicles.
Performance & Handling
Driving the Ground Pounder monster truck is the kind of
experience that brings me back to my childhood. Watching the monster
truck perform reminds me of going to the centrum with my Dad to see all
the big name monsters.
If there is one thing that truly makes the Ground
Pounder feel like a real monster truck, it's the four wheel steering.
The four different settings explained in the radio section of this
article are awesome. With a touch of your finger you can switch through
the four different steering modes. It is an absolute blast jumping from
one setting to another while pounding the ground. All I need now is a
the roar of a dimly lit stadium with multiple camera flashes glistening
off the body of the freshly polished monster truck.
While the Ground Pounder is a blast to drive, it does
have a few adjustments that need to be made from the transmitter.
Steering EPA needs to be set. This allows you to set the overall range
of the steering servo so you are not putting unnecessary strain on the
servos or steering components. This will help keep the tires from
rubbing the springs as well. Don't worry about having enough steering,
the four wheel steering provides plenty.
The front and rear steering trim also needs to be set.
To achieve straight tracking, adjust the "DT1" lever above the steering
wheel to center the front tires and the "DT4" lever on the handle to
center the rear tires.
There is one other thing you may want to check. I was
having a little trouble at first with the steering. Upon inspection, I
realized that the front and rear steering servos were plugged into the
wrong channels on the receiver. This is easy to correct and will only
take a few seconds. Just plug the front servo into channel 1 and the
rear servo into channel 3. I was told by RedCat Racing that there was
some confusion at the factory because this is such a new truck. They
assured me it was being taken care of.
The suspension is still a little stiff and the
landings are a bit bouncy but it reminds me of the 1980s monster
trucks. Very fun! You are now "READY TO RUMBLE."
Acceleration and top speed are adequate for this style
of vehicle. When compared to the competition it does really well. You
won't break any land speed records but it's enough for high levels of
fun, however it wouldn't hurt to have more torque. While trying to
creep over or stopping mid way through an obstacle, the 540 motor had a
tendency to want to stall. As long as I entered the obstacle with a
little momentum the motor had plenty of power to conquer it.
The solid axles contain gearing that will support
stronger brushed or brushless motors so if you require more horse
power, it shouldn't be a problem. With a brushless system this thing
would be crazy.
I noticed while bashing that the rear wheels steered in
the wrong direction while in mode 4. Apart from that, steering was
tight and accurate. The servos have enough power to turn the vehicle
where you want it to go and both servos continued to work smoothly
after the pounding. The truck was able to turn sharply and dust was
I found that the Ground Pounder is easy to work on.
Everything is layed out neatly with plenty of room for big fingers like
mine. The vehicle can quickly be torn down and reassembled for cleaning
For those of you who have children, they will love this
thing! My two boys (6yrs & 9yrs) talked me into driving their
stuffed animals around. This quickly evolved into a big event with
checkered flag and all. We stacked the couch pillows on the rug and had
our own little monster truck arena. This was before I got the truck
dirty of coarse. I may be weird but I'm not crazy!
The boys had a blast. Stuffed animals were flying
everywhere and the monster truck was jumping over our home made jump.
That was probably the most enjoyable time I had in a while. I know my
boys enjoyed it as well. I labelled the clip bonus footage and included
I am impressed with the parts used on the Ground Pounder.

Great looking body
The Ground Pounder is loads of fun and is perfect for beginners as well
as the seasoned hobbyist. My boys do well driving this and it's durable
enough for beginner mistakes.
The Ground Pounder will also make a great platform for
the fanatic who wants to build the biggest and baddest monster truck.
The axles are filled with metal gears so they can handle all the power
you can throw at them.
The RedCat Racing Ground Pounder is one of a kind and
has a great future ahead of it. This truck has something for everyone.
I give it a thumbs up!
