Trinity NEXT User manual

PLEASE READ BEFORE STARTING!
Before you throw down this manual and try to
start your NEXT Truggy, please continue read-
ing for just a few minutes. In addition to impor-
tant safety precautions, below you will also nd
some quick tips for getting the maximum en-
joyment out of your new nitro vehicle.
We would sincerely like to thank you for your
purchase and hope that you enjoy the fun
and excitement that come from owning a high
performance nitro R/C vehicle.
SAFETY GUIDELINES
NEXT Truggy is not intended for use by chil-
dren without direct supervision of a responsi-
ble, knowledgeable adult. Trinity Products Inc.
shall not be liable for any loss or damages,
whether direct, indirect, special, incidental, or
consequential, arising from the use, misuse, or
abuse of this product and/or any product or ac-
cessory required to operate this product.
IMPORTANT POINTS TO REMEMBER
Always, turn on your transmitter rst before
turning on your vehicle’s receiver switch.
When turning an R/C vehicle off, the order is
just the opposite; turn the receiver switch off
rst and then turn the transmitter off. Just re-
member that when your truck is turned ON,
your transmitter should always be turned ON.
If not, your NEXT Truggy will no longer be un-
der the control of your transmitter, and could
unexpectedly take off on its own causing dam-
age to itself and other people.
Never use old, worn out batteries in your trans-
mitter or truck. Use only fresh alkaline batter-
ies or fully charged rechargeable batteries to
ensure that you will not exceed the range of
your radio system while driving your truck.
Nitro vehicle engines get very hot. Take care
when handling your vehicle to keep from burn-
ing your ngers.
Keep nitro fuel away from all sources of heat
and open ame.
Keep nitro fuel away from eyes and do not
take internally. If ingested follow instructions
on the fuel container and call physician.
Never use cleaning spray of any kind on your
Truggy until it is completely cooled down. Us-
ing cleaning spray on a hot engine will cause
a re.
Make sure you always keep the exhaust point-
ing away from your hands and face as hot
exhaust gasses and unburned fuel will be ex-
pelled when the engine is running.
Never store your Truggy with fuel in the tank.
Only run your Truggy in safe, open areas that
will not put anything or anyone in danger of
a collision. Use common sense when driving
your truck to insure that you are not causing a
potential hazard to anyone (crowds of people
and conned areas should be avoided).
Although the NEXT Truggy is small and light-
weight, it can still hurt when it runs into you at
ankle height. It can also startle someone who
is not expecting it, so it is extremely important
to ALWAYS keep a safe distance between any
people and the path of your truck (don’t forget
this includes yourself).
Never run your NEXT Truggy through puddles,
wet grass, snow or any other type of moisture.
Also never use any liquid cleaners around the
electronic components on your NEXT Truggy.
Any small amount of moisture can cause se-
vere damage to your electronics.
If you will be running with other R/C vehicles,
always conrm before turning your transmit-
ter on, that no one else is using your same
frequency channel. If necessary, you may
change frequencies.
Always let your cool down completely between
runs (2 tanks of fuel) when the weather is hot.
Over heating the engine will cause failure of
the plug and could cause damage to the en-
gine. Always let your engine cool down with
the piston at the bottom of the stroke, the point
in the engine revolution where there is no re-
sistance.
Prolonged running on high drag surfaces like
grass, can cause excessive heat and cause
premature failure of the clutch and engine.
GETTING STARTED
The rst thing you need to do is install the bat-
teries in your transmitter and into the radio box
to power the receiver.
8 “AA” batteries go into the bottom of the
transmitter and 4 “AAA” batteries go in the cell
holder located in the radio box.
By removing the clip that holds the lid on you
will see the battery holder that holds the 4
“AAA” cells.
Check the life and proper installation of your
batteries by switching the transmitter to on.
You should see all three LED’s light up (red,
yellow, and green). If you do not, your batter-
ies may be low on voltage or you may not
have installed them all correctly.
As the life of your transmitter batteries begins
to decline, the green LED will no longer light.
When you notice that you are down to only
the yellow and red lights, this is a caution sign
that it is time to install new batteries. We rec-
ommend changing both the transmitter and
receiver batteries at the same time. If you con-
tinue operating your Truggy and
see that the yellow light goes out (and only
the red light is lit), STOP IMMEDIATELY! Your
Truggy may easily travel out of range causing
you to lose all control, which could result in a
collision causing damage to the vehicle
or other property.
ASSEMBLING THE ANTENNA
Locate the plastic antenna tube (found inside
the box). Also locate the black antenna wire
coming out the radio box. Thread the antenna
wire into the plastic antenna tube until it comes
out the other side. Pull the remaining wire
through the tube, and then press the tube into
the antenna mount in the lid of the radio box.
Bend the antenna wire down around the tube
and install the black rubber antenna cap
on the top of the tube. You may then wrap the
remaining wire around the tube.
DO NOT cut the antenna wire off! This could
shorten the range of your radio system.
LEARNING THE TRANSMITTER
Before turning on your Truggy, please famil-
iarize yourself with the controls and adjust-
ments of the radio transmitter. You may use
the following diagram to conrm the location
and function of each of these features.
A - ON/OFF Switch: Controls power to the
transmitter.
B - Steering Wheel: Steers the vehicle left and
right.
C - Throttle Trigger: Controls the speed and
the brakes of the vehicle.
D - Throttle Trim: Adjusts the neutral position

transmitter, and gently press it into place. DO
NOT force the crystal! The pins can easily be
broken!
Remove the crystal from your receiver in the
same careful manner. The crystal extends from
the side of the radio box.
PLEASE NOTE: It is very important that the
crystal labeled “T” is installed in the transmitter
and the crystal marked “R” is installed in the
receiver.
KNOWING YOUR ENGINE
BEFORE STARTING YOUR ENGINE
The air lter is one of the most critical compo-
nents of your car engine. A well maintained air
ltration system will increase the life expectan-
cy of your engine.
Remember to keep it clean and to check for
replacement often. Running your engine for
a second with the lter off can destroy your
engine. Dirt getting inside the carburetor will
grind the piston and sleeve away causing the
engine to lose compression and fail.
Before starting your engine, put a few drops of
lter oil, household oil caster oil or automotive
motor oil on the outside surface of the air lter
and rub it into the surface. This will help the l-
ter trap more dirt and dust. NEVER USE SILI-
CONE SHOCK OIL AS IT DOES NOT BURN
AND WILL FOUL THE ENGINE.
FUEL
Use only top quality model two-stroke engine
fuel. We only recommend Trinity MH0020 20%
Monster Horsepower or TRI4300 Monster
Brew Fuel because of the known oil quality
and content. Use of any other fuel will void any
warranty on the engine.
CARBURETOR
Carburetors are pre-adjusted and only a ne
adjustment may be required. As your engine
breaks in the adjustment will change and of
course the weather effects the settings. The
settings we offer are basic all around settings.
Two adjustable needles are provided on your
carburetor.
The high speed needle (the big screw on the
top) is for adjusting the mixture when the throt-
tle is fully open. If you turn the needle coun-
ter-clockwise you will make the mixture richer,
more fuel. Turning the needle clockwise will
make the mixture leaner, less fuel.
The low speed needle (small screw on the bot-
tom) is for adjusting the mixture strength at
part-throttle and idling speeds, to obtain steady
idling and smooth acceleration to mid speeds.
of the throttle so your truck responds correctly
to the trigger.
E - Steering Trim: Adjusts the center position
of the steering so your truck travels straight.
F - Throttle Reverse Switch: Reverses the for-
ward/ reverse direction of your throttle trigger.
G - Steering Reverse Switch: Reverses the
left/right direction of the steering wheel.
H - Antenna: Transmits radio signals to your
receiver.
I - Frequency Crystal: Controls the operating
frequency (channel) of your transmitter.
J - Battery Power Indicators: Signal when it is
time to replace your transmitter batteries.
Please familiarize yourself with the function of
the steering and throttle controls as shown be-
low Like most other pistol grip style radio sys-
tems, the reverse function of the transmitter
applies the brakes. This function needs to be
used to slow/stop your Truggy and to keep it
stationary while it idles.
RUNNING MULTIPLE TRUGGIES
If you have some buddies that would like to get
a NEXT Truggy of their own or already have
friends with other RC vehicles that you will be
racing with, it is very important that you rst
check what frequency channel your Truggy
is on and conrm that none of your friends
have the same frequency as you.
If you do nd that someone else is using the
same frequency channel that you are, you
must either wait for them to turn their trans-
mitter and vehicle OFF or you may choose to
change the frequency crystals in your transmit-
ter and receiver (so that you can run together
at the same time without causing any radio
interference). Additional frequency crystal sets
can be purchased separately and installed in a
few quick seconds.
To change frequency crystals simply remove
the black plastic crystal holder from the back of
your transmitter by carefully pulling it straight
out. Slide the crystal out of the holder and in-
stall the new crystal labeled “T” in its place.
Carefully align the two pins that extend from
the crystal with the socket in the back of your
If you turn the needle counter-clockwise you
will make the mixture richer, more fuel. Turn-
ing the needle clockwise will make the mixture
leaner, less fuel.
Basic carburetor settings. 2 to 2.5 turns out
from having the needles screwed all the way
in. This is the setting for both needles.
Adjusting a nitro engine can be a tricky pro-
cess. We recommend you have an expert help
you the rst time you run your Truggy.
BREAK-IN
The rst time the engine is started it should be
used with a very rich mixture setting, basically
as rich as the engine will run. Engines require
a running-in of about 10-20 minutes using
moderate rpm. During this running-in period
a lot of smoke and oil should come out of the
mufer, indicating excessive lubrication.
The default needle setting of the carburetor is
a good starting place for break-in.
ALWAYS REMEMBER SMOKE IS GOOD!
YOU ALWAYS WANT TO SEE SMOKE WHEN
RUNNING YOUR ENGINE.
Start tuning only after you have given the en-
gine 2 to 3 minutes to warm up to its full oper-
ating temperature. Do not tune it before then,
a cold engine will seem to run rich but will lean
out on its own as it approaches its operating
temperature.
Once your engine is broken in and idling and
running well, you can tune the high speed
needle by turning it in slightly to lean out the
engine and make more power. Remember to
make 1/16th to 1/8 of a turn at a time. It is a
small engine and only small adjustments are
necessary. Remember you always need to
see smoke when running at full throttle. That
means the engine is getting enough oil.
Weather effects the tuning of your engine. You
need to run it rich, (more fuel) in hot weather
and leaner, (less fuel) in cold weather.

GLOW PLUGS
Most times the inability to start your engine is
due to failure of the glow plug. The glow plug
on nitro engines is a disposable commodity
like fuel. We recommend replacing the plug as
a rst step if you have trouble starting your en-
gine. Most racers will start out with a new plug
when running there car for the rst time each
day. We recommend the McCoy 9 as the best
all around plug.
PULL STARTER
When using it do not pull it to it’s whole length,
but use quick short pulls. If these is exces-
sive resistance make sure the engine is not
ooded. You may have hydro-locked it and
cause damage by trying to pull the pull start. If
you ood engine, remove the plug and pull the
starter a few times to pump out the extra fuel.
CARE AND MAINTENANCE
At the end of each operating session, drain the
fuel tank. Afterwards energize the glow plug
and try to restart the engine, to burn off any
fuel that may remain inside the engine. Repeat
this procedure until the engine fails to re.
To reach the delicate parts of the engine you
only need to unscrew the glow plug and than
you can wash out the engine with Trinity Nitro
Blast RC4449 and lubricate it with Final Solu-
tion Engine Run Oil RC8104. These mainte-
nance procedures will reduce the risk of corro-
sion after a period of storage.
The air lter should also be regularly checked
and cleaned or replaced if necessary.
STARTING YOUR ENGINE
After reading all of the above information, you
are likely ready to get started. It is much easier
to start your car with 2 people especially when
the engine is new. One person to start it and
the other to blip the throttle to keep the engine
running. Just proceed as follows:
Make sure your glow plug charger is fully
charged.
Fill your fuel tank. Make sure the ller cap is
fully closed so the tank stays pressurized.
Turn on your transmitter, pull up the anten-
na and turn on the receiver. Test the radio to
make sure that the throttle and steering work
smoothly and in the correct direction. The
throttle servo should pull away from the carbu-
retor under full power. When pushing the trig-
ger forward the brake should engage and the
car should not be able to be pushed forward
by hand.
It either servo works in the wrong direction
simply using the servo reversing switches on
the transmitter to change the direction.
Pull the starter a few times and you should see
the fuel move from the tank into the carbure-
tor. Holding your nger over the exhaust pipe
exit will help suck the fuel into the engine a
little easier.
Clip the glow starter to your plug. Wait a few
seconds for the plug to heat up. Hold down
on the glow starter to insure a good connec-
tion and rapidly pull the starter in quick short
bursts. The pull start should have some resis-
tance but be easy to pull.
If it is very hard you have the engine ooded.
Stop what you are doing, remove the plug turn
the car upside down and pull the starter a few
times. The excess fuel will squirt out of the
plug hole. Watch your eyes. Reinstall the plug
and you are ready to go.
The engine should re after a few fast short
pulls and as soon as it does blip the throttle to
keep it running until it warms up and starts to
idle smoothly. Some times it helps to give the
radio 1/4 throttle while starting it to get more
air into the mixture. You can do this simply by
turning up the throttle trim, (clockwise) 25 to
50%. Once the engine warms up turn it back
all the way to counter clockwise.
After a minute remove the glow starter and blip
the throttle to make sure it is getting enough
fuel. Once the engine warms up and breaks in
it will idle at a lower speed and produce more
power at top seed.
Run through the rst 2 tanks of fuel with the
stock settings, making sure the engine smokes
a lot. This will allow the piston and sleeve to
properly break-in. Run in a 30 foot oval pattern
and vary the throttle from low to 1/2 throttle.
Let the engine cool completely between tanks
of fuel so you do not over heat it during the
break in process.
After the rst 2 tanks turn the big high speed
needle clockwise 1/8th turn and run 2 more
tanks of fuel running the oval pattern again.
Vary the throttle from low to full but only go to
full throttle for a few second, (2 or 3) at a time.
TUNING YOUR ENGINE
Once you have your engine broken in and run-
ning well you can start to tune it. Unless you
have a temperature gauge where you can
monitor head temperature, (try to stay below
220 degrees) you have to use the visible tun-
ing aid of blue smoke coming from the pipe.
As long as the pipe is smoking under top
speed you are getting enough oil to the en-
gine and you will be OK. Turn the high speed
needle in, (clockwise) to lean out the engine
1/16 to 1/8 of a turn at a time. Make a few high
speed passes. You will notice a higher pitch
sound and more power.
If your engine cuts out during a high speed
run, sounds like it is starving for fuel or stops
blowing out smoke you are too lean and you
need to stop immediately and turn the high
speed needle counter clockwise 1/2 the adjust-
ment you just made to lean it out and run a few
more laps.
When adjusted correctly your engine should
see a nice crisp sound all the way down the
straight, run through a tank of fuel with out
changing and blow smoke constantly. The
smoke is a big deal as that means enough oil
is getting to the engine. No smoke and you
can cause serious damage to the piston and
sleeve.
In most cases the low speed needle will not
need any adjustments. You can use the low
speed needle to adjust your idle speed. Turn-
ing it in, (clockwise) leans out the engine in-
creasing idle speed while turning it out, (coun-
ter clockwise) will decrease idle speed. You
always want your engine to idle as slow as
possible with out stalling.
TROUBLE SHOOTING
You have run your engine and now it simply
will not start no matter how many times you
pull the pull start. The rst thing to check is
your glow plug. Remove the plug and put it in
the glow ignitor while holding it with a pliers
as it will get hot. Check to see if the coil glows
red. If it doe not it needs to be replaced.
Still won’t start? Then the best thing to do is to
put your settings back to a point where the en-
gine should run.
Make sure the idle adjustment is not set too
low. Take the air lter off and look into the
carburetor. there should be a 1/16th to 3/32
opening in the throttle body for the air to ow
through. If this opening is too small the en-
gine will be starved for air. You can adjust this
by turning the throttle trim on your radio to the
right.
If the idle setting looks ne than you will proba-
bly have to adjust the low speed needle. Turn
the needle all the way clockwise until it stops.
Than turn it out 2 1/2 turns. 2 to 2.5 turns is the
point where most engines will run.
Make sure your fuel tank lid if snapped closed
when running the engine.

Make sure the fuel line is not pinched by a chassis component or by the
body.
RULES OF NITRO ENGINES
Every nitro engine has it’s own personality and will require slightly dif-
ferent settings than every other engine. It takes some time to get a new
engine dialed in but once you get the setting down it will run the same
every time.
Always run your engine rich. Too rich is better than lean. When the en-
gine is running rich it is getting enough oil, when it is too lean it is not
and could overheat and damage the engine. Running too lean can ruin
your plug in one tank of fuel.
An easy way to remember is the oil is mixed with the fuel, so the more
fuel you put through the engine the better lubricated it will be. Rich is
more fuel than air, lean is more air than fuel.
R/C nitro engines run very hot, over 200 degrees. It is easy to burn your
hands and ngers, so be careful.
When you adjust a setting on the carburetor, the motor needs to run for
at least 30 seconds for the motor temperature to adjust to the new set-
ting before you can tell if that setting works better or worse.
The single most important thing when it comes to tuning a nitro motor is
having a lot of patience.
