the price, I can't complain!
Monster XX, made by Extreme Machines RC, is a 1/10 scale AWD ready-to-run
hobby grade RC truck sold at Target for under $100.
Lets take a look at what sets the MonsterXX apart from the other
toys on Target's shelves and try to figure out how they were able
to get the price so low.

MonsterXX was packaged like a typical "shelf item,"
with a clear front package so isle dwellers can easily see what's
the package you won't find a typical toy grade RC. The appearance
of the Monster XX is like any other hobby grade RC. The graphics
are printed on the inside of the plastic shell, which is held
on by four body clips. There's even a small wing attached to the
rear of the body.
aggressive over sized tires are of medium firmness which will
offer plenty of traction as well as sufficient wear.
black plastic chassis looks very much like the DF02 chassis made
by one of RCs leading kit manufacturers. On the left you'll find
the rear facing motor which sits behind the electronic speed controller,
receiver, and steering servo. The center drive shaft runs down
the center of the chassis while the right side is designated for
lower arm and upper fixed link make up the suspension. The plastic
seems to be sturdy and the design looks beefy enough to handle
a life of bashing. The upper suspension links as well as steering
links are solid plastic and are of fixed length. The suspension
arms are held to the chassis by a curved u-shaped pin which secures
both left and right arms. The front pin is held in by the front
bumper and the rear by the rear bumper. There is no binding of
the suspension components and every thing moves freely.
coil over shocks soften hard landings while providing an exciting
amount of bounce. The shock bodies are of oil free construction
despite their appearance.
simple shock tower design doubles as a body post perch. The plastic
again appears to be sturdy from its dimensional design.
550 brushed motor, with cool blue heat sink, drives a nylon spur
gear. The spur gear splits the power between the front and rear
differentials. The rear of the spur gear is connected to a metal
bevel gear that drives the rear differential. A plastic drive
shaft which rides the center of the chassis delivers power to
the front differential. The two differentials are constructed
using all metal gears which are lubed with grease.
one end of the metal dog bone drive shafts, four plastic diff
cups consist of a metal inner shaft and plastic outer cup. On
the other end of the dog bones, the wheel drive cups of the same
basic construction secure the wheels and are suspended by plastic
bushings. Lock nuts ensure the wheels will stay in place through
all that bashing.

2-channel AM radio system with servo reversing, steering trim,
and throttle trim also includes a steering dual rate knob. The
pistol style controller has a foam padded steering knob for comfortable
gripping. An unlabeled receiver is mounted to the steering servo
using foam servo tape.
standard size steering servo is protected by a plastic servo saver
speed control & Motor
fin cooled electronic speed control is mounted to the chassis
with servo tape. The brushed 550 motor is cooled by the blue anodized
heat sink. An on/off switch is mounted, face down, to the chassis
behind the motor. Screws hold the switch securely in place.

most likely place this vehicle will be driven is the yard, so
that's where I did my testing. The monster XX drove through the
grass and fallen leaves with ease. The large tires made a spectacle
out of throwing the leaves into the air. This truck is equally
at home on pavement as in the grass.
leave covered driveway proved to be exciting. The Monster XX's
low center of gravity allows for stable cornering at top speed.
Applying steering and full brake will send the truck into a tail
truck responded well to the controller inputs however, I noticed
while adjusting the steering trim, the trim knob operated in reverse.
The actual steering was fine and I was still able to make the
necessary trim adjustments through out testing.
This vehicle uses digital proportional throttle and steering,
so if a small throttle input is given, the vehicle will drive
slow. As you steadily increase the throttle input, the vehicle
gets faster. The same goes for the steering controls.
Monster XX is definitely a fun truck to drive. The bouncy suspension
reminds me of my very first hobby grade monster truck. My mother
bought it for me in 1989 and after building the kit, my black
monster truck was the coolest thing in the neighborhood. I drove
circles around the other radio controls on the block. Yeah, those
were good times. Well, back to present time.
placed a skate board ramp in the yard and hit it full speed several
times. The large tires allow easy flight control. I wasn't able
to produce enough wheel spin for a backflip on the small ramp,
but it still jumped great.
truck held together very well. After several battery charges and
both my son and I driving, the Monster XX came through with no
major damage. The front diff began to make a little noise after
several hard landings, but it still operated fine. I inspected
the gears and noticed no excess wear, so I think a shim might
quiet it down a bit. The boys made several single wheel landings
(cartwheels) and all plastic parts with stood the beating just
test the top speed, I ran the Monster XX up and down the street
in front of my house. I taped my Garmin GPS unit to the truck
and set it to record top speed. It was obvious the tires were
out of balance, which caused some unwanted wheel bounce. After
a few runs, I checked the GPS and it recorded a top speed of 19.5
MPH. I decided to clear the top speed readings and give it a few
more tries. After several more attempts, the GPS screen read 19.5
MPH. That's close to the claimed 20 MPH and without the excess
wheel bounce, I'd of probably reached it.

Monster XX is a great way for someone to be introduced into the
hobby. I'm not recommending anyone trade in their 1/8 scales by
any means but, for someone on a strict budget, this would make
a great first truck.
one thing that makes this truck stand way above toy grade RCs,
it's upgradable. All electronics can easily be swapped out as
a drivers skills increase and when the demand for a greater top
speed increases, drop in an after market motor. This is important
for those who like to keep their first RC vehicles for many, many
