| You
Can Race a Nitro Gas R/C Car or Truck!
Michael:
This BMW RC car is fun for all kinds of age. I even enjoyed playing around the
house. It is very durable and the battery does no run out quickly, it can go
on carpet, wooden floor and on grass.
Sunil: I purchased this car about 4 weeks ago and ever since
i have had endless fun both driving it around my garden and shopping for performance
parts that can be easily be attached to the car itself to make it go faster
and look different with new polycarbonate shells.
Envy Michael
and Sunil? It's unnecessary to envy them because you can get the same or even
better experience too. The only limit is your imagination!
Nitro
gas rc cars
Many people prefer nitro gas rc cars to electric ones because nitro cars can
run faster, which provides a liittle bit more fun and high-speed excitement!
Nitro gas rc cars are actually powered by a small engine that burns a special
glow fuel. Some can reach speeds of over 50 mph! We recommend gas cars for advanced
modelers.
How
a nitro rc car engines operates
RC car nitro engines are two-stroke (two-cycle), and most larger engines are
almost always four-stroke- with the exception of things like small lawnmowers
or scooter engines. Being 2-stroke means that it really is a very straightforward
thing, as there are no valves, cams or lifters that are found in a 4-cycle engine.

Bentz 4WD RC Nitro Gas 2Speed Car RTR- 15CXP Engine can speed up to 50mph!
Two-stroke means that the
piston just needs to complete one down-stroke and one up-stroke within the combustion
chamber to complete the process of drawing the fuel and air in and then converting
the ignited mixture into raw power and also expelling the exhaust gases.
The piston
will keep on moving up and down so long as the fuel/air mixture is being ignited,
the fuel/air mixture needs to be introduced into the crankcase at the bottom
of the combustion chamber before anything can happen. This is done by 'priming'
the engine.Either action makes sure that fuel is put into the crankcase.
Now that fuel is in the
crankcase and has mixed with air, the glow plug needs to heat up and the piston
needs to move up and down. So to start, the nitro engine needs to be turned
over manually, which is either done with the pull cord, if it is a pullstart
engine, or by an electrical engine starter. At the same time, the plug is made
to glow red hot by connecting a special battery to it for a few seconds; the
core of the plug heats up immediately.
With the fuel/air mix sitting
in the crankcase, it needs to be moved up to the top of the chamber and ignited.
It's moved to the top as the piston moves down; as it does so it pressurises
the area of the crankcase where the fuel/air mix is and forces it up small ports,
or channels, that run up to the top of the chamber. The mixture is then ignited
by the glow plug on the top of the engine.
When the piston is at the
point just before the mixture ignites, it is covering the exhaust ports which
run from the sides of the combustion chamber through to the silencer. When the
piston has almost reached the top, the fuel/air mix ignites because of the glow
plug, and the resulting explosion forces the piston back down again. On the
way down, the exhaust ports are uncovered by the piston and the burnt gas mixture
leaves the chamber via the ports. The momentum of the spinning crankshaft makes
the piston move upwards again and the whole process starts over.
Although the glow plug was made to glow red hot initially by a battery, once
the engine has begun to run then the high temperature inside the combustion
chamber keeps the plug glowing. If the plug fails, then the fuel/air mix will
not get ignited and the engine will stop
How
to choose and buy nitro gas rc cars
1. RTR, ARR or Kits
There are 3 ways for you to buy nitro gas powered rc cars. This first
one is 'RTR' (Ready To Run - motor & radio gear fully installed and set
up, body pre-painted), the second one is 'ARR' (Almost Ready To Run - no motor
or radio gear but otherwise pretty complete and usually pre-painted) and the
last one is pure 'Kits' (all the components need to be added to the basic chassis,
piece by piece. )
Following
are 2 popular RTR nitro gas rc cars and one comes with a complete kit from Hobby-estore
The advantage to build a
kit yourself is that you will know how to repair any possible damage. Even if
you are never built a kit before, you also can have a big try. You need not
be worried about anything- nitro car kits always come with pretty comprehensive
instruction manuals and if the worst comes to the worst, a visit to your local
hobby shop for help in putting the car together would always solve any problems.
The choice is purely down to your own personal preference and in part depends
on your interest in building models or just your interest to get driving as
easily and as quickly as possible.
Check out our nitro gas rc cars.
2. On
Road or Off Road
Nitro rc cars can be purchased for both On-Road or Off-Road driving. The most
popular type of R/C car is the Off-Road Buggy. Big tires with "knobby"
spikes, full-travel suspension parts and a high ground clearance allow the off-roader
to go almost anywhere. Most are 1/10 scale (about 15" long), are either
two-wheel drive (2WD) or four-wheel-drive (4WD), and reach speeds of 15-30 mph.
On-Road cars usually have lower ground clearances, slicks tires, aerodynamic
bodies, and are capable of a bit higher speeds.
The
1:10 RC Nitro Gas Car-2Speed Smartech 4WD Buggy Off Road are created with
a mind for high performance racing, speed of 55mph+.
You may make the choice
due to your personal preference; you may want the high speed thrill of racing
round a tarmac track, or you may love the idea of racing over humps and through
mud and puddles! Off-road cars will probably need a bit more maintenance than
on-road racers because they sustain more 'wear and tear' due to being driven
over much rougher terrain, but also much more fun!!

On- Road nitro gas rc buggies and cars.

On- Road nitro gas rc trucks.
3. Two-Wheel Drive
Vs. Four-Wheel Drive
In four-wheeled vehicles, there are two main drive types: two-wheel drive (2WD)
and four-wheel drive (4WD). If you're new to R/C, you may want to consider 2WD.
They generally require less overall assembly and maintenance. The tradeoff is
that 4WD vehicles offer easier driving and a definite handling edge.
4. 1/10th or 1/8th scale, 1/5 .12 size or .15 size
1/10th scale gas cars
are usually powered by .12 size engines that have around to 1 horsepower. Normal
speeds are in the range of 30 mph, but some are capable of speeds in excess
of 50 mph like .15 size nitro cars- XPro Engine of Hobby-estore. Normally, the
bigger the size is, the faster the car can run. 1/10 nitro cars are good for
beginners. However, big size engines are mainly for experienced rc car racers
not beginners.
There are many types of gas powered RC cars to choose from. You can start
with our fast 1/10th scale gas cars, and as you gain experience, move on
to the even faster
1/8th scale category.
Tips
on rc car racing
These are some basic rules that all cars need, but as far as the actual setup
goes, different cars react differently to the same adjustments. Also, all tracks
are different, Conditions are different, and driving styles are different.
1. Basic
Pro racers today is not only building the car, but taking time with it. Racers
should make sure that everything is moving freely. For example, pop off the
shock and make sure that all of the suspension arms are moving freely. Also,
take off the steering linkage and make sure the steering is free. A) You could
have dirt in the pulleys. B.) The belt could be too tight. C.) The bearings
could be gritty and cause lots of friction, the list goes on! Also, another
important thing is to make sure that neither belt is coming in contact with
your electronics or any wires. This can save your money and frustration.
2. Check the racing schedule
You can check out the schedule for rc racing at http://www.rcracing.com/Race_Schedule_284.cfm.
Also you may go to some rc clubs or forums on the net and communicate with others.
After you check out the racing date, you should go to the prepare step!
3. Preparing
Preparing for race day is a very important thing. The first thing you should
do is pull out a new or slightly used set of tires. Slap them on the car and
find a VERY flat surface. Set up the car carfully.
4. At the track
Ask your buddies or someone who is pitted near you what the tire is for the
day. Go ahead and try it. tires are probably the most important thing at a race.
If you don't have the tire that everyone seems to like lately, don't expect
your car to be off the hook! Another thing that only does good is PRACTICE!
Track time is another thing probably more valuable than anything! Also, try
all of the tires you have if you have the time. If the car is tweaked, re set
the tweak, if the tires suck, try other tires. If the car has too much steering,
all you have to do is turn down the dual rate! If the car doesn't have enough
steering, turn up the DR.
You'd better to find the
right balance. This means that the car steers into the turn just as you want
it too, and comes out of the turn just as you want it to. Say the car has a
push going into the turn, and has kind of an over-steer coming out of the turn.
In this situation, put one of your smallest shock shims in both of the rear
shocks. This will raise the rear ride height and give you more bite in the rear
coming out of the turn, and more bite in the front going into the turn. If the
car does the opposite (over-steers going into the turn and under-steers coming
out), then put 2 of your smallest shims in both of the front shocks. Do this
until you find the right balance.
After you do all the steps well, you are expected to enjoy the racing!
Nitro RC Car Maintenance
1. Keep the car clean
The fuels we use in rc nitro cars and trucks contain a number of lubricants
in their mixture. While these lubricants protect your engine, not all of them
are burned off when your engine runs. The result is a chassis that¡¯s coated
with oil that exits from the pipe. The easiest way to remove this gunk is to
use a degreaser such as Simple Green, or Nitro-specific cleaners. Before you
start blasting your chassis, remove all your radio equipment and plug any inlets
on your engine (or if you really want to do a good job, remove your engine).
Lightly spray your chassis down, and with a firm-bristled brush start to knock
that grime away. When your chassis is clean, dry it off with a shop towel and
re-install any components you removed. Remember, keep the car
clean!
2. Leave the car some oil
The engine of rc car or truck is a delicately tuned piece of hardware.
You can remove your glow plug when you are done running for the day to extend
the time between piston and sleeve replacements due to corrosion. Rotate the
crank by hand till the piston is at bottom dead center. At this point, squeeze
a few drops of after-run oil into the combustion chamber. To evenly spread the
oil around, rotate your crankshaft a few times to make sure that the after-run
oil is evenly distributed. After-run oil helps prevent leftover lubricants from
any un-spent fuel from breaking down and gumming everything up and also inhibits
rust.
3. Recharge or replace the battery timely
Both your glow plug and glow driver need relatively constant attention to ensure
your engine will start promptly and your vehicle will run well. If your glow
driver is a rechargeable unit without a voltmeter built into it (low voltage
means you need to recharge the battery), you can place a fresh glow plug into
the driver to see if it lights the coil up. If it doesn't, recharge your glow
driver's battery. If you are using an alkaline battery and the coil doesn't
light up, it's time to replace the battery.
Glow plugs don't
last forever. If you never know when you might have a plug go bad, you can test
the glow plug the same way you test your glow driver. Remove the plug from the
head, load it into your driver, and if all of the coils light, you're good to
go.
4. Take
care of the starter
Usually, most RTR cars come with some kind of electric starter unit or pull
starter. The one-way bearings in the starters should be cleaned and oiled every
few weeks or so. You should carefully remove the starter unit from the engine.
Use a screwdriver to keep pressure on the recoil mechanism as you pull the starter
off the back plate, in this way the spring won¡¯t pop out and ruin your day.
Use motor or engine cleaning spray to clean out the bearing, then oil it with
a light oil to keep it spinning smooth. Then reassemble the engine and the starter
should work like new.
5. Attention to the air filter
Don¡¯t be careless about the air filter. You'd better wash the foam element
in warm, soapy water and then rinse and dry it thoroughly. Add some air filter
oil into a plastic bag, drop in your filter and scrunch the filter to make the
fluid into the element.
6. Need more power?
Most of the nitro rc cars typically have a 4 or 5-cell battery onboard to power
servos and a receiver. You can upgrade to a 5-cell rechargeable pack as your
budget allows. The alkaline batteries may seem less expensive today, but they
will cost you more in the long run. If your servo movement has begun to slow
down, it¡¯s time to recharge or replace your onboard pack.
7. Store your fuel well
You need to store your fuel in a dry place away from small
children, pets, and Uncle Fred who thinks it may be windshield washer fluid
(yes it has happened). Don't store a half-gallon of fuel for a year and think
it will be as good as new nitro fuel can absorb water vapor over time if the
bottle is not perfectly sealed or if the bottle is half empty and there is humidity
in the air with the fuel. You'd better put bottle on cardboard, not directly
on carpet or cement and make sure the seal is firmly tightened.
RC
Racing Organizations
IFMAR Introduction
IFMAR (International Federation of Model Auto Racing) is the world governing
body of professional RC Championship racing. Organized in 1979 by Ted Longshaw
after many exhausting attempts to bring all of the current Pro RC Racing organizations
together under one roof. It was his enthusiasm for our hobby of radio controlled
vehicles that set the stage for a unified World Championship RC Racing.
Purpose of IFMAR:
IFMAR, a highly respected organization, has established a uniform set of construction
rules for radio controlled racing, ensuring everyone operates within the same
guidelines.
In fact, in their Constitution,
the first clause states that IFMAR exists to promote international friendship.
IFMAR's goal has been to ensure that there be only one official World Championship
of each class. To this day, they have succeeded in both of these imperatives.
Coverage Area:
IFMAR governs the World of RC Racing through four blocs. These organizations
are:
EFRA
FEMCA
ROAR
FAMAR
Each govern their own bloc,
and comprise an impressive total of 42 member countries. All member blocs have
full voting rights within IFMAR.
IFMAR - International Federation
of Model Automobile Racing
IFMAR is the governing body of professional radio controlled racing. Their leadership
is carried over into four organizations that comprise the 42 member countries.
These blocs, as they are called, meet every two years to hold RC World Championship
Racing. Nearly every scale is represented.
EFRA - European Federation of RC Automobiles:
EFRA's bloc consists of Austria, Belgium, Croatia, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Great Britain, Greece, Holland, Hungary,
Ireland, Italy, Luxembourg, Monaco, Norway, Poland, Portugal, Romania, Russia,
Slovak Republic, Slovenia, Spain, Sweden, and Switzerland.
FEMCA - Far East Model Car
Association:
The EFRA bloc governs Australia, Brunei, China, Hong Kong, Indonesia, Japan,
South Korea, Macau, Malaysia, New Zealand, Singapore, Taiwan, Thailand, and
The Philippines.
ROAR - Remotely Operated
Racers:
ROAR's bloc consists of the United States of America and Canada, and is responsible
for promoting r/paces in their coverage area. The ROAR race team represents
the USA and Canada at IFMAR World Championship races. More World Champions have
emerged from ROAR membership than any of the four IFMAR blocs.
FAMAR - Fourth Association
of Model Auto Racing:
FAMAR is the newest IFMAR bloc and its' member countries include Argentina,
Brazil, Mexico, South Africa, Uruguay, and Venezuela.
