Earlier
this year I did a review of a nitro power RC truck from
the standpoint of a beginner in RC cars and trucks. Since
I had very little experience with nitro powered RC vehicles
it was very easy for me to look at the truck through the
eyes of somebody just getting started in them. After seeing
this review, Eddie Hickey owner of Himoto Racing USA,
asked me if I would review one of his trucks "before
I learned too much in the hobby". He asked if I would
do this review still looking at it from the point of view
of somebody just getting into the hobby, or wanted a truck
to simply "play" around with occasionally. He
wanted me to look at the vehicle from somebody who wasn't
going to race or compete with it, but somebody that wasn't
going to "baby" it while they played with it.
I'm the guy for that as I've never been one to take it
easy on things such as this!! After looking at the truck
he wanted to send me I jumped at the opportunity! He wanted
to send me the Himoto Racing MegaP MXT-2S truck.
HimotoRacingUsa.com says this about the MXT-2S:
"The
MegaP with its .stump pulling 3.0cc pull start Japan
CXP engine gives the Model blistering acceleration.
HIMOTO RACING designed the MegaP with a fully sealed
radio box.
Keeping your electronics safe and sound is critical
to having Nitro RC fun day in day out.

coupled with a slipper clutch to maximize power transfer
and enhance traction.
Equipped with 75cc fuel tank and lightweight chassis,
the MegaP provides over ten minutes of tire shredding
fun on a tank of nitro. Less refueling and more Driving!"
Since
I have no plans on racing or doing any other competition
with this truck I thought that it would be perfect for
my son and me to go out and occasionally "bash"
with it. I wanted to do this review from the standpoint
of somebody who simply wants a RC vehicle to take out
and have some fun with without having to spend lots
of money for the vehicle and then spend more to "upgrade"
it in order to keep it running. So with these guidelines
I want to look at a vehicle that has a low learning
curve, is simple to setup, easy to use, durable enough
to not break often, and most importantly simply fun
to drive. So with that in mind let's dive in and take
a look at this vehicle and see if it's what I am looking
for......

Unpacking
The Box
The
outer box for the MegaP is big; it leaves no doubt
that the vehicle inside is big as well. The box
is printed with full color pictures of the MXT-2S.
The side panels of the box are printed with specs
for the vehicle as well as all items that are needed
to get the truck up and running. Opening the box
reveals the fully assembled vehicle, which is padded
for shipping with cardboard spacers that the wheels
of the vehicle are inserted into. If you look at
the first picture above you will see that the edges
of the box did sustain a little bit of shipping
damage, but the vehicle and contents of the box
were well protected and not damaged in any way.
At one end of the box is an additional box, which
contains the transmitter radio, the radio antenna,
vehicle antenna tube, and the instruction manual.
The Transmitter is wrapped in bubble wrap to protect
it from shipping damage.
The
Manual
At first glance the manual looks to be thin, but
that doesn't mean that it is lacking in information.
The manual is printed in Black and White, and is
printed in English only. The front page of the manual
identifies which vehicle it is for. Opening the
manual the first page lists the equipment, materials,
and supplies that are needed to get the vehicle
running. Also listed in this part of the manual
are the instructions on getting the transmitter
prepared for use.
The next section (not shown in pictures) lists instructions
for starting and tuning the engine. These instructions
are detailed and do a good job of instructing the
owner on getting their engine started and how to
tune it for running.
Located in the middle of the manual is a parts diagram
that has a blow-up view of the vehicle that shows
every part on the vehicle and provides part numbers
for each part of the vehicle. This section will
be invaluable when it comes time to do maintenance
on the vehicle, or to replace any parts. This diagram
will show how everything is put together and how
to take it apart and put it back together. I would
highly recommend making a copy of this page in case
anything spills on the original or it is damaged
in any other way. I have scanned the image from
the manual, which allows me to "blow-up"
the diagram to see all the details better.
Listed next is the Break-in procedure for the engine.
This is probably the most important section of the
manual. The manner in which an engine is broken-in
will determine how it's going to run. It will make
the difference in how long the engine will last
as well. An engine that isn't properly broken-in
will often be damaged or destroy itself early in
its running life. So please pay attention on this
section. Luckily the instructions here are well
written and very easy to understand. If the instructions
are followed the owner will be rewarded with an
engine that will give them a long life of running
in the vehicle.
The last section of the manual is a list of all
the parts on the vehicle. This list is used in conjunction
with the blow-up view of the vehicle, so I would
recommend copying this section as well.
The
transmitter, or controller, for the MXT-2S is a
pistol grip style, which is the standard for RC
vehicles today. It is a two-channel transmitter
that controls the throttle/brakes and the steering
on the vehicle. The throttle/brakes are controlled
by the pistol "trigger" control, which
has a small guard that fits around the finger of
the operator in order to allow them to apply the
brakes of the vehicle. By pulling backwards on the
trigger the throttle of the vehicle is operated
throughout its range of operation. By pushing the
trigger totally forward the brakes are engaged to
stop the vehicle. Located in the middle of the upper
section is the steering wheel, which controls the
steering of the vehicle. By turning the wheel to
the right or left the wheels of the vehicle can
be steered. The wheel is spring-loaded and will
return to its center position when released. The
radio transmits in the 75 Mhz frequency ranges,
which have been reserved in the US for ground type
RC vehicles.
The
antenna for the transmitter is installed by placing
it in the mounting hole in the top of the transmitter
and screwing the antenna in place to secure it.
The antenna telescopes out to its full length for
operation. Located on the back of the radio is the
On/Off switch.
The front portion of the transmitter has 2 trim
tabs used to fine-tune each channel of the radio
to provide better control. Also located here are
3 LED lights, which indicate the power level of
the batteries in the transmitter. The transmitter
requires 8 AA sized batteries to operate it. The
manual indicates to use good quality alkaline batteries
in order to run the transmitter. Located on the
underside of the transmitter directly behind the
pistol grip is a recharging jack that can be used
to recharge the batteries in the transmitter without
removing them if rechargeable batteries are used.
NOTE: Never attempt to charge batteries that
are not designed to be recharged, as this can result
in a fire or explosion of the batteries. A charger
will need to be purchased separately if rechargeable
batteries are used in the transmitter
The
Vehicle
As
the vehicle is removed from the box the wheels will
be surrounded by the cardboard inserts that protect
the vehicle during shipping. These simply pull off.
Also, the body of the vehicle is wrapped in plastic
to protect it. Removing the shipping materials reveals
the MXT-2S in all its glory! This is quite an impressive
looking truck!
The body of the MXT-2S is made of lightweight Lexan
plastic and is mounted to the vehicle by four mounting
posts and is secured in place by a cotter pin on each
post. To remove the body simply pull the four pins out
and lift the body off of its mounting posts.
Lifting the body off of the truck lets us get a good
look at what makes the MXT-2S tick. The MXT-2S has two
main body parts, a lower metal plate and an upper mount
made of plastic. All of the components of the vehicle
mount to these two assemblies.

With
the mindset of this review being those who have little or
no RC experience the setup of this vehicle will probably be
the biggest thing on their mind. "What do I have to do
the set it up?" I can hear those words being asked out
there. I do know that the box says that this truck is called
"Ready To Run" (RTR), but that is still a bit deceiving
as there are some things that will need to be done before
we can run this vehicle. Let's take a look at what someone
will need to do to get this truck up and running.
One of the biggest assets to Himoto vehicles is the support
forum that they maintain here on RCU:
Himoto Support Forum. This is the best place to get answers
for questions that might come up with getting this vehicle
running. The US dealer for Himoto Racing, Eddie Hickey, has
established a crack team of people to help answer any question
about a Himoto vehicle. Many questions have already been answered
in this forum and a quick search of it will turn up answers
for many questions that you may have. If you don't find an
answer please don't hesitate to ask. Many questions will be
answered quickly and professionally as this group is dedicated
to getting you running. On top of that, they are a great group
of guys that just want to see others have as much fun with
their vehicles as they do. Support questions can also be sent
directly to Himoto Racing USA by email. The address is

Batteries:
Batteries are as much of the lifeblood for this vehicle as
the fuel is, since the radio doesn't work without them. The
MXT-2S requires 12 AA Alkaline batteries, 8 for the transmitter
and 4 in the receiver. The receiver has a battery clip to
place the batteries in. Once the batteries are in place wrap
a piece of electrical tape around the clip to keep the batteries
from vibrating out of place while the vehicle is running.
This is important because a bad connection can result in loss
of control for the vehicle, which could result in damage to
the vehicle or injury to others if it hits somebody. The transmitter
batteries are located in the bottom of the transmitter and
have an access panel that slides out to reveal the batteries.
While a set of batteries should easily last for several running
sessions, the cost of using regular Alkaline batteries could
rack up quickly. To avoid this I choose to use Energizer rechargeable
Nickle-Metal Hydride (Ni-MH) 2500 Mah batteries in my vehicle.
I use these because I already use them in many devices in my
house that use AA batteries. such as digital cameras and flashlights.
They greatly cut down the cost of batteries and the 2500 Mah
size gives plenty of juice for power hungry devices. The batteries
can be removed from the vehicle and transmitter to recharge
them in the Energizer recharger that I purchased with these
batteries. As I mentioned earlier, the transmitter does have
a recharge jack that will recharge the batteries while they
remain in the transmitter, but a separate charger designed to
recharge 9.6V (total voltage of the batteries in the transmitter)
battery packs will be needed to recharge them.
The receiver battery pack was one of the downsides I found with
this vehicle. I felt it was a little bit cumbersome to remove
the hatch of the battery compartment in order to access the
batteries to recharge them. Granted the hatch is secured with
a simple pin, but I would have preferred that a recharge jack
be provided to recharge the receiver batteries without removing
them from the vehicle. This is only a minor nuisance and doesn't
detract for the operation of the vehicle. It's just a minor
pet peeve I had with it.
Radio setup:
There really isn't much setup to do with the radio, as most
everything is already in place. The transmitter antenna needs
to be installed, but this is as simple as screwing it in place
on the top of the transmitter. The receiver antenna is a small
wire that is approximately 3' in length which is coiled up under
the body of the vehicle as it comes of out of the box. This
antenna must be extended before running the vehicle, as failing
to do so will result in loss of control of the truck. A plastic
tube is provided to mount the antenna wire in. The antenna is
extended up through the tube and then the tube is inserted into
the recess provided in the vehicle chassis. The excess wire
is then wrapped back down around the outside of the antenna
tube. I used a small piece of heat shrink to secure the end
of the wire to the tube, but a piece of electrical tape could
be used here as well.
When it comes time to run the vehicle the On/Off switch is
easy to access with the body in place. The switch is located
in the front left corner of the chassis and is easily reached
by simply running your finger up under the body of the truck
immediately behind the right front wheel.
Truck
Body & Chassis:
The body of the MXT-2S sits high enough to provide plenty of
airflow to the engine to properly cool it down as it's run,
so cooling holes won't need to be cut into the body. However,
you may want to cut a hole in the back of the truck to allow
access for a glow starter and the pull start handle. The truck
can be started without this access hole by removing the body
and starting it, and then replacing the body after the engine
is running. While the body is secured with 4 cotter pins, it
can still be a bit of a pain to have to remove the body every
time you need to start the truck. It's a very easy process to
cut out a hole above the engine and the pull starter. This will
allow easy access to place the glow starter on the engine and
use the pull starter to start the engine.
Along the same lines here is a quick tip that I picked up from
the Himoto Support Forum on RCU. Attach a small zip tie to the
lip of the fuel tank, and leave the excess portion of the tie
in place. This will provide a small handle for lifting the lid
of the fuel tank when it comes time to refuel the truck. By
doing this you can reach into the hole cut into the back of
the truck and lift the lid for easy access to refuel the tank
without having to take the body off the vehicle.
One
very important part on the chassis is to go through and make
sure that all of the screws on the vehicle are tight. All
screws, nuts, and bolts that are metal to metal contact need
to have blue Lock-tite applied to keep them from vibrating
loose.
Engine break-in:
This is probably the most important part of setting up a glow
power RC vehicle. This one step will dictate how the vehicle
runs throughout it's life, and also dictate how long it lasts.
An engine is a machine with many moving metal parts that must
"seat" against each other. If an engine is pushed
too hard before these parts are properly seated the engine
usually won't last long or run well either. On the other hand,
if it is properly broken-in the engine will last a long time
and will run at it's peak best. The break-in process is completely
spelled out in the instruction manual and can be easily accomplished
in an afternoon. The process for breaking in the engine will
take 5 full tanks of fuel that will be run through the engine,
with different steps taken as each tank is run.
Some things to remember during the break-in procedure.
Leave the body off of the vehicle. This will allow the engine
to run cooler.
Always leave the air cleaner on the engine whenever it's running.
Run the vehicle on a smooth hard surface. A parking lot is
perfect for this.
Use the same fuel for break-in that you will use for normal
running.
Don't make quick acceleration or deceleration moves while
breaking-in the engine.
Keep a couple of glow plugs on hand while breaking in the
engine as they are prone to go out.
DO NOT overheat the engine while breaking-in. Check the head
temperature with an electronic temperature gauge to monitor
it's getting too hot.
Use an electronic thermometer to monitor the engine
temp during break-in
Leave the body off while breaking-in the engine
Use a glow drive to heat the glow plug while starting
the engine
Break-in procedures
Tank
1 For the first tank the engine should be run at a very
rich needle valve setting. This allows the fuel to provide
as much oil as possible to lubricate the parts during the
break-in process. Open the high speed needle valve 4-1/2
turns from fully closed. After starting the engine run the
truck on a smooth hard surface with the body off. Run back
and forth at a medium speed, slowly accelerating and decelerating.
Run the truck until the tank is almost out of fuel. Do not
allow the tank to run dry during break-in as this can cause
overheating in the engine. Allow the engine to completely
cool before proceeding to Tank 2, normally about 10-15 minutes.
Adjusting the high speed
needle
Tank 2 Lean the high-speed needle 1/2 turn from the setting
during Tank 1 and restart the engine. Run the truck in the
same manner as during the first tank. Allow the engine to
completely cool before proceeding to Tank 3.
Tank 3 Lean the high-speed needle another 1/2 turn from the
Tank 2 setting and repeat the steps from the last 2 tanks.
Allow the engine to completely cool before proceeding to
Tank 4.
Tank 4 Lean the needle another 1/2 turn from tank 3 settings
and run the buddy for the entire tank. Allow it to cool
before moving to tank 5
Tank 5. Lean the needle another 1/2 turn from tank 4 and again
run the vehicle for the entire tank and allow the engine
to cool. The engine is now broken-in and can be tuned for
performance. You will probably notice that the idle will
be higher than when you started and will need to be adjusted.
And
that's it. The truck is now ready to go out and "play".
While this may seem a bit involved it's really not. All of
these steps can easily be accomplished in an afternoon and
don't involve any special procedures.
Now
let's take the truck out and have some fun!!
With
the engine broken-in it was time to pack up the
MXT-2S and head down the street to a local park
to see what it could do. We have a good park that
is fully of gulleys and ditches that make for
some great places to run a truck like the MegaP.
Once we were there I fueled up the truck and fired
up the engines. At first we took it a bit easy
on the truck, just running it in an open area
so that we could get a feel for how it handled.
The first thing I noticed was the responsiveness
of the engine. When I applied throttle it was
very quick to apply power to the wheels and get
the truck up and running. This also made for a
fast truck. I was really impressed with just how
quick the truck was on the open ground. I hadn't
expected quite that much speed. It didn't take
too long before the truck was out of fuel and
it was time to fill it back up. This was one thing
that I did notice throughout the day that I was
a bit disappointed with the amount of run time
the truck had from a tank of fuel. I would have
hoped it lasted longer. However it's not a huge
deal because the truck can quickly be refueled
and started back up to continue running.
After playing with the truck on the open ground
we decided to set up a small ramp with a board
and some rock. At first we started off not very
high just to see how the truck did, but it didn't
take too long before we needed to raise it up
so we could get some "air" in the jumps.
I was really impressed with the MXT while we were
doing these jumps. During this time my lack of
skill with the throttle resulted in some less
than perfect landings that really punished the
truck, but nothing broke. I liked that the truck
was able to take the beating while we learned
to work the throttle in the air to keep the truck
in position for a good landing.
Up next was time to open the truck up and bash
it in the ditches in the park. I really liked
doing this, as it was a lot of fun running up
and down the hills of the park. The truck really
handled them well and it was very easy to keep
control of it as it was run. As a final test we
decided to combine the hills with the jump to
really put the truck to a test. This really put
a beating on the truck as it had a lot of less-than-perfect
landings that were hard on it. Once again, no
damage at all to the truck.
Overall we ran about 15 tanks of fuel through
the truck. We would have run more but it was time
to head home for dinner. The MegaP really provided
a lot of great fun for both my son and me as we
had a blast putting it through its paces. One
thing was sure, it was going to see a lot more
running time in the upcoming weeks as we "played"
with it more!
So,
what did I think of the Himoto MegaP MXT-2S? Absolutely
a blast to run. The truck provided myself and my son with
loads of fun that didn't require excessive amounts of
prep time or lots of maintenance afterwards. We really
pushed the truck hard as we ran it and it took all of
the punishment that we could put to it. Now I know that
at some time in the future something is bound to break
on the truck, but it was nice to see a product that performed
well right out of the box. And if something does break
I'm positive that it will be easy to get the parts to
repair it. I've spoken to several RCU members that own
Himoto vehicles and they have nothing but great things
to say about Himoto Racing USA and their commitment to
providing their customers with great products and outstanding
support for those products.
There were a few things that I would have liked to see
done a little bit better. A larger fuel tank would have
been nice, as the run times seemed a bit short. I also
felt that the receiver battery box was a bit cumbersome
to get open for changing, or recharging, the receiver
batteries. I felt that a charging plug would have been
nice on the receiver box. While these items could have
been done a bit better they in no means mean that this
isn't a great truck to start out with. They were minor
annoyances and easily overcome by the enjoyment of running
this truck.
For somebody who has little or no experience with glow
fuel powered RC vehicles I can recommend the MXT-2S as
a great vehicle to start out with. It's simple enough
to get set up and running that even beginners will not
have any problems getting started. But the larger size
of a 1/8th scale vehicle, and the quality of the Himoto
truck, will ensure that the owner of this truck won't
grow tired of it quickly. It's sure to give a long life
of running that will make it a fantastic bargain for the
cost. Overall I would say it's a great vehicle to get
started on.
With
great performance and a reasonable price the MXT-2S
is a great RC product for those out there who just want
to have some fun with their RC vehicles.
Got very little use out of my truck,it just fell apart.First I lost a rear drive shaft,it fell out and had to buy a new one.Then the muffler came lose and lost a lot of back presure on the motor (no power).Then the air filter fell off and that was lost.It was fun at first but would not have wasted my money on it if I had know it would self destruct.The first time I had it out in a feild was the best time after that it was all down hill.
