It?s no secret the Rampage XB-E is a big buggy. Everything
on this thing is big. Removing the buggy from its box revealed
the XB-E is no lightweight either.
The buggy was packaged well and arrived safely to my door. The
rear wing needs to be installed, which is very simple. The XB-E
includes a set of six allen wrenches, a six way socket wrench,
instruction manual, 2.4GHz radio, two 3s LiPO battery packs, and
The manual includes an exploded view as well as parts reference.
The XB-E chassis is 0.4cm thick and consists of a lower deck
with upper brace. The screws in the XB-E chassis are countersunk.
Wheels, tires, and drive train
The 6? tall medium compound tires are mounted to black
plastic wheels and are able to shred the ground with their big
The drive train is beefy as well. A steel spur gear drives two
steel center dog bone drive shafts. These drive shafts command
the front and rear differential units. The XB-E has two large
fluid filled differentials.
Inside the differential you will notice only two planetary gears.
This is because they are oversized and don?t leave enough
room for a third. These diffs look like they can hold up to much
The rear of the vehicle uses large dog-bone drive shafts while
the front takes advantage of CVD joints. Did I mention everything
on this buggy is huge?
I have a single issue so far. The drive shafts appear to be a
little long. I noticed this when setting camber. Setting the desired
camber squeezes down on the dog-bones and adds unwanted stress
to the suspension components. My only option was to leave the
camber alone and hope it handles well.
Center Drive Shafts
Single Speed Spur Gear
The suspension design is similar to that of an 1/8 scale buggy
and offers many adjustments. The lower H-Arm and upper adjustable
link support the hub carrier. The suspension parts are made of
Sway bars are used in the front and rear to increase stability.
The aluminum adjustable shocks are threaded for quick adjustments
and can be mounted at different angles for different handling
characteristics. The shock towers are of metal construction with
a plastic overlay.
Oil filled shock
A 2.4GHz radio system is included with the Rampage XB-E. The
transmitter runs off eight AA batteries and includes functions
such as servo reversing, steering and throttle trims, steering
dual rates, and a bind button.
The receiver is safely enclosed in it's own box with an on/off
switch mounted on top. There is no label on the receiver, so I'm
not sure of the brand. During testing, it worked flawlessly.
The huge steering servo, measuring 2.5" across (NOT including
mounting tabs), is held in place with four screws and is protected
by an adjustable servo saver.
Motor & ESC
Fan Cooled ESC
Motor , ESC, and battery packs
The Rampage XB-E is equipped with a 150 Amp Hobbywing brushless
electronic speed controller which regulates current to the 980Kv
brushless motor. An electric fan aids in cooling the Hobbywing
ESC and large cooling fins help to keep the motor cool.
Like everything else on this buggy, the motor and ESC are big.
The brushless motor is almost as long as one of the 3s LiPo battery
packs. Speaking of battery packs, the Rampage XB-E includes two
3s 3600mah LiPO battery packs. That makes a total of 22.2volts
with a moderate discharge rating of 25c.
A LiPO balance charger is also included with this RTR combo which
is great news for beginners. Like all RTR kit chargers, it's easy
to get tired of waiting for the batteries to charge. The included
charger will put out a charge current ranging from 0.5A to 0.8A.
That's not much current for charging 3s LiPO packs, which is why
a higher power charger will soon be a good buy. The included charger
does have both 3s and 2s charging capabilities.

Performance & Handling
I'll start by addressing the power capabilities. The Rampage
XB-E has plenty of power! I had to be careful where I tested this
buggy because of it's shredding capabilities. If grass upsets
you, this buggy will excite you. If you haven't figured it out
yet, you guessed it, it tears up the lawn.
The beautiful green grass at public parks were absolutely out
of the question as testing grounds. It didn't take me long to
realize my front lawn probably wasn't the best area for testing
either. I was thinking how cool it was watching the grass fly
into the air and my wife was thinking how busy I was going to
be spreading seed. I may not have gotten to raw dirt, but I could
easily see the tracks in the yard where the XB-E tore up the grass.
I didn't want to go through the normal testing routine with this
buggy because I felt it offered much more than other buggies and
large scale vehicles, which is why I decided to go to the woods
first. With its large scale and 4WD drive train, many options
open up for having fun with this beast. I was able to blast over
rough terrain containing dirt, rocks, fallen limbs, grass, and
thick leaves. I even barreled through thick brush with little
The power is evident when slamming the throttle. Anything that
starts out under the XB-E, ends up on top of or behind it. There
is some strange sense of accomplishment and empowerment when driving
the XB-E. ?I am Man, I tear up lawn.? It's large size
is great for overcoming larger obstacles and the 4WD is great
for getting through the tough stuff.
The 1/5 scale size of the Rampage XB-E gives it the illusion
of going slower than it really is. 38 mph seems more like 30 mph
from a distance. There is no mystical reason for this illusion,
plain and simple, it's BIG! 38 mph is nothing to sneeze at for
a vehicle of this size. Just don't run into your leg.
I finally brought the XB-E to the local outdoor track. The water
supply was still turned off from the winter months so the track
was dry. This caused the XB-E to behave in a loose manner. I personally
don't mind this because I tend to set my vehicles up a little
The XB-E had no trouble maneuvering around the tight corners
with its sharp turning radius. The XB-E feels secure and planted
which takes the worry out of rolling over. Exiting the corners
was eventful. The dry hard packed surface made the XB-E struggle
for traction. Most corners were taken at 1/4 throttle and gradually
increased to full during the exit phase.
Because of it's size, the XB-E seldom saw full throttle inputs
while on the 1/8 scale track. With that being said, you can see
in the video it still got around the track quickly. Due to its
weight, it?s necessary to steer sooner to account for the
Jumps went well as long as you hit them straight on. A vehicle
of this size has less forgiveness than an 1/8 or 1/10 scale buggy.
When I noticed the XB-E in an awkward midair frontal flip, I applied
full brake to save the suspension components from damage. Stressing
a single A-arm due to an uneven landing will eventually break
these large suspension components. I found it safer to land flat
on the roof than on just one wheel.
Hitting the jumps straight on produced desirable results. The
nose tends to hang slightly and some throttle input pulls the
nose up level in most cases.
The XB-E is easy to drive and offers many pleasing driving characteristics.
I would say that overall, the XB-E is stable, responsive, and

The Rampage XB-E is definitely fun and easy to drive. Because
of its size and 4 wheel drive system, there's not many places
the XB-E won't go. Below are a few items I decided to rate separately
to summarize my experience with the Rampage XB-E.
Hard surface= Good
Grass= Great (the Shredder)
Loose dirt= Great
Hard packed dirt= Moderate
Good (Depending on my driving style, it ranged from 8-12 minutes)
