yeah, I'm a first year nitro/pro-performance rc car enthusiast and this helped alot, my traxas nitro rustler(2.5 engine as in most traxas of that gen.) came with a video that talked about the high speed but not nearly this deeply. Thanks alot!! =D
Make sure you do less than half throttle to warm the engine up for a minute or two, you can also put needle up a little to stop it cutting out when you brake
yeah the stock tuning from what i go from is to level the high speed needle and the low speed, and to have 1mm clearance on the carburetor when the throttle is pushed closed. this is also the break in setting.
Nice, I had a RC motor sitting for a few years and it seized there was ne way to pull start it because it was locked up frozen, so I took the glow plug out put a small screw driver on top of the piston and smacked it really hard with the hammer, and it worked! Hasn't run better even though there is a cross shape from the screw driver on the piston haha
@iamthewalrus026 you have to lean up the mix abit because its pushing tomuch nitro through and prime your car first by putting you finger over the exhaust when not running then try starting it without the glow starter and do so for 10 secs then put glow starter on and it should be fine when u start it . P.s. only try turning it over 10 secs at a time due to you can break your starter gerabox
This is crazy, proper way to tune is with a temp gun, or onboard temp controller (those that will record Hi/Lo temps are better). Tune according to track conditions, what works on loose ground is not the same as asphalt (never ever). And make sure your stop screw is set 1/8!
you need to adjust the carborators idle speed so that it slightly makes the engine rev more, but not so that it turns the wheels just enough to keep it running.
i was reccommended an ansmann virus buggy as i was just starting this awesome hobby. they cost around 190 pounds rtr or 90 pounds for the rolling chassis. that isnt bad paying 190 because the top speed is around 45mph.
The only thing he didn't go into with this vid well is idle needle which is prolly explained in another vid anyway.. But for those of you who are asking on this page.. If your rc car is trying to take off while it's just sitting there then ur idle needle aka the unspecified third needle, is too high. If ur rc car is new you shouldn't have to adjust it much.
@MKerror the same thing happened with my gv dominator. I believe it's because the engine is new. After breaking my engine in it became alot easier to pull.
WoodyW123, tell you what. I'm not familiar with how the servo will be connected to the throttle. But if it's exposed, or you can get at it, disconnect the servo from the throttle on the engine and see if it still revs up when you start it. My hunch is that it won't, and that you will be able to control the revs by directly manipulating the throttle on the engine. If anyone knows better than me, they are welcome to speak up. :)
check ur carb. mine was doing that and i took the engine out. when i pulled the fuel line off the carb there was some gunk clogged in the fuel intake nipple. i only found this out the other day and im still putting it back together so i can't tell u for sure if that was the prob. i told my local dealer bout that and he said that could have been the case.
Dude i fixed mine. It was a faulty glow plug. Fixed it everything is fine. And my idle was too high, lowered it and its working fine. TMAXX OWNZ ALL. Forget the savage!!!!
i just got a new thunder tiger car and couldn't get it started after i adjusted the needle valve according to the manual, it turns out that when i screwed the needle valve all the way in then turned it out the correct number of times, the end of the needle broke off & clogged it up proper, have a look at yours if you've adjusted it much
These things are great if your willing to blow as much money on a real car as you would these! when i was into driving these I spent more time fixing the damn thing and upgrading the parts than actually driving it haha.
Same here but I just decided I'd go out and buy some new glow plugs and air filter oil and throw more money into it. It's an incredibly expensive and almost as difficult hobby. Go for electrics, I say.
I've got an nitro boat and it does have the lsn and hsn but i can't tell which way round they are. The engine is a kyosho GT engine and it looks quite old.
clean your air filter, get a new glow plug installed, and watch this video and follow it again, and if there are ever fumes that burn your eyes, lean it out a little
u need a new cylidner thingy but i would check on why it came off in the 1st place, i got my 1st nitro rc last week & nearly everything has fell off it due to screws etc. not being tightened up in the factory.
I need to know if this would work, I have got a CEN Magnum NX and it came with pre-glued wheels and tyres except the have no inserts, I was wondering if there was anyway of putting foam in them, I know this sounds really stupid but would making a small hole then filling them with that squirty expanding foam work? Thanks, Huntyfm
im considering getting one but i noticed the cost of nitrotane fuel...not the cheap, so i was wondering if rc cars the run on nitrotane also run on just ur normal everyday gas?
I have a GS Racing Avenger MK II and it only has a high-speed needle, ive checked all over the engine and i cant find an idle-speed or low-speed needle. does that mean that its been factory tuned, and i only can control the high speed? on does the one needle do it all? i have a kyosho on road petrol car and it has an idle speed needle, so im confused about my other one. do you know anything about this? (i know youre not from GS Racing, but youre pretty knowledgeable) thanks
i av the kyosho land max 2 but its a bit slower than usual. i cant remember if i mukd about with the settings and i just started using different fuel. do i just av 2 adjust the needle valve?
it is a bad glow plug, even though it glows it only glows when the ignitor is in, when the engine is running the glow plug still glows even without the ignitor in,just get a new plug, also if they blow quickly richen both needles 1/8 turn.
hi if i take my nitro car traxx to the hobby shop will they just put iy bk to its standerd setings or proper tunne it up for me as only cost 20 qued for them to look at it so recon be beter off?
This is a really helpful vid, but what should I do if my nitro doesn't have a low speed needle? Maybe i can't find it but maybe it doesn't have it! Is this a problem? I've got a Nb16 t if that's any help?
WoodyW123, I'm not an expert on nitro, but this could easily be a problem with the electronics such as with the calibration or the controls or a fault in the electronics. Does the problem go away once it's warmed up? If so that would suggest it probably is a nitro problem rather than an electronics problem. That's not conclusive, but a start :)
i have 2.5 tamiya xgb n wen ever u start it starts to roll real slowly but wen it hold on to the breaks its stops but i don't i just keeps on rolling is there something wrong with ma tuning ?
Hey im new to high performance rc cars. I want to get a nitro car but im not sure which one. I want to get a car that is ready to run and is under 3 hundred any suggestions. I was looking at the hpi firestorm. Is it good?
Im currently breaking in my engine and i've got half throttle but when i accelarate at about half throttle the car bogs and stalls ,this also happens when i brake to.Any help please !!!
I have a Revo 2.5 that I cant get started. Last year I found it very difficult to get the right setting but now I cant even get it started :( What can I do???
hey, i just picked my savage 4.6 up yesterday and broke it in today when idling it just goes does any one know what i should do so that it wont go unless my hands on the trottle?
hey mate i need YOUR help... my nitro rc car cuts out at full throttle no matter what i try... could i use instead of 25% nitro fuel... shall i use 15% or 20%... i tried altering the carb thing it runs perfect just as i say it cuts out at about 80% throttle... thanks any help much apreciated :)
I have a traxxas t maxx 3.3 with no reverse. When i drive it to full trottle and go into idle position, the engine just turns off. Plz someone tell me wat to do.
Im just a newbie at this nitro stuff but im gonna try answer using my knowlege from sleds and quads. Maybe your car is running to rich and it 'bogs' so try make it leaner
can someone help me? my nitro rc car is a 4wd and the back wheels dont move...the cylinder shaped thingy came off where u put the drive shaft in..when i tighten it it still comes off anyone know what im talking about? the thing that looks like (()) and the drive shaft goes into the middle
Best R/C Nitro tuning video on UA-cam I've seen so far. Seen about 20.

Really really good tuning video. best i have seen
Thats Cred, you should get an award
this video is great, recommend to all the nitro nuts in the world
an excellent help. better than the manual that came with my truck.
Good video. Thanks for all the tips!

he isnt wrong. you are, this is the best and only good way

thanks mate.. really helped.. my car was begining to do me head in... Cheers
Fantastic video mate, really good quality production and instruction mate thanks.
yes because the enging has more lubrication so its less likley to get hot and it stops the piston running dry

i am going to the hobby shop today i am gonna look at the firestorm, rustler, and i heard they have a used brushless emaxx that would be good to
thx man this helped alot... i really needed this THX
MAN... leep posting em..
you may need to adjust the throttle linkage for the cutting out. i dont know about the smoke though
the savage xl is pretty beast but if ur kinda new at how these things work and need to be maintained u shold go with an savage x.
fantastic video!
good video it helped a lot. what kind of truck is that big foot??
Dude i fixed mine. It was a faulty glow plug. Fixed it everything is fine. And my idle was too high, lowered it and its working fine.
TMAXX OWNZ ALL. Forget the savage!!!!
they do tune the enginge..... for the break in process
its your job to tune it to how you want
thank you so much i really needed help
verry helpfull like the "anticlockwise"
i just got a new thunder tiger car and couldn't get it started after i adjusted the needle valve according to the manual, it turns out that when i screwed the needle valve all the way in then turned it out the correct number of times, the end of the needle broke off & clogged it up proper, have a look at yours if you've adjusted it much

GOOOOOOOOOOOOOOOOOOOOOOOOOOD !!! Swietne
nice instructions i wish i had a 25 like that

excellent video.
Try the following:
High speed needle: 3½ turns.
Low speed needle: 3 turns.
(Based on my KYOSHO GZ15 2,5ccm)
I was looking for this :p
excellent video
clean your air filter, get a new glow plug installed, and watch this video and follow it again, and if there are ever fumes that burn your eyes, lean it out a little

turn the idle needle down so that it doesnt move at standstill and just enough to keep the engine running at idle.
@CJLongoproduction09 Some older cheaper cars do not have an low speed.
That was helpful. Thanks.
great video
i only dont understand 1 needle there are 3 but there is one close to the air filter with a spring on it wanna know where that one is for
I need to know if this would work, I have got a CEN Magnum NX and it came with pre-glued wheels and tyres except the have no inserts, I was wondering if there was anyway of putting foam in them, I know this sounds really stupid but would making a small hole then filling them with that squirty expanding foam work?

thanks i want on ofroad car that geos at least 35 mph
is the firestorm good i think it will do 40mph
i have a Volcano S30 1/10 Scale Nitro Monster Truck and when i floor it, the motor stalls... so should i only adjust the hi speed needle to rich
i av the kyosho land max 2 but its a bit slower than usual. i cant remember if i mukd about with the settings and i just started using different fuel. do i just av 2 adjust the needle valve?
it is a bad glow plug, even though it glows it only glows when the ignitor is in, when the engine is running the glow plug still glows even without the ignitor in,just get a new plug, also if they blow quickly richen both needles 1/8 turn.
adjust the idle. its a small screw on the carburater
hi if i take my nitro car traxx to the hobby shop will they just put iy bk to its standerd setings or proper tunne it up for me as only cost 20 qued for them to look at it so recon be beter off?
i have 3 needles on my hsp tornado, high speed (the big one with the fuel line) only under it, and one on the throttle thing, what one is what?
Make your idle speed somewhat higer by turning the little screw in..
with idle, do you turn it down, so the wheels dont turn at all? or so they are spinning slowly?
then just tune the high needle but you might want to double check cuz iv nvr heared of a engine with 1 needle
what needle do i need to turn if i still have gas coming out of the exoust please help me
This is a really helpful vid, but what should I do if my nitro doesn't have a low speed needle? Maybe i can't find it but maybe it doesn't have it! Is this a problem? I've got a Nb16 t if that's any help?
Low speed. But the needles are set from the factory for optimum break in air/fuel ratio.
newbie question: does smaller engine have to be retuned more often than bigger ones?
WoodyW123, I'm not an expert on nitro, but this could easily be a problem with the electronics such as with the calibration or the controls or a fault in the electronics. Does the problem go away once it's warmed up? If so that would suggest it probably is a nitro problem rather than an electronics problem. That's not conclusive, but a start :)
i have 2.5 tamiya xgb n wen ever u start it starts to roll real slowly but wen it hold on to the breaks its stops but i don't i just keeps on rolling is there something wrong with ma tuning ?
thats sounds like the one way bearing
when it happens...slowly pull it up, and hopefully it should catch...once it does pull fast. it may not work tho
Hey im new to high performance rc cars. I want to get a nitro car but im not sure which one. I want to get a car that is ready to run and is under 3 hundred any suggestions.
I was looking at the hpi firestorm. Is it good?
Im currently breaking in my engine and i've got half throttle but when i accelarate at about half throttle the car bogs and stalls ,this also happens when i brake to.Any help please !!!
I have a Revo 2.5 that I cant get started. Last year I found it very difficult to get the right setting but now I cant even get it started :(
What can I do???
the front wheel cups just might be loose. check if you already havrnt returnrd it yet.
was it blowing alot of blue smoke and running hot? let me know how it turns out thanks
hey what happens if the smoke is not blue but red or a different color?
ok where do i set the needle's to begin with? i missed that part
u use the idle needle if the car moves and your not touching the throttle, thus the name idle needle
So. What if my engine stops when i brake. How do i avoid that? It runs smooth on both idle and high speed. But when i try braking it stops
hey, i just picked my savage 4.6 up yesterday and broke it in today when idling it just goes does any one know what i should do so that it wont go unless my hands on the trottle?
hey mate i need YOUR help...
my nitro rc car cuts out at full throttle no matter what i try...
could i use instead of 25% nitro fuel... shall i use 15% or 20%...
i tried altering the carb thing it runs perfect just as i say it cuts out at about 80% throttle...
thanks any help much apreciated :)
But it still dies, also when i use the pull start i pull it and it looses pressure, so it wont take any energy to pull it why?
I have a traxxas t maxx 3.3 with no reverse. When i drive it to full trottle and go into idle position, the engine just turns off. Plz someone tell me wat to do.
Thanks this is realy helpfull ;)
Just bought a 2nd hand truck....anyone know why it runs fast when i start it up?Im new to this so i really dont know a great deal.Thanks.
whats faster a force 18 abc engine
or a 15bx
i got my first nitro coming soon
i have tryed all of this but my engine still shuts down when i leave it to idle. i even riched high speed and low speed but it still shuts down.
Im just a newbie at this nitro stuff but im gonna try answer using my knowlege from sleds and quads. Maybe your car is running to rich and it 'bogs' so try make it leaner
can some one help me i have nitro monster truck but if i leave it to warm up it cuts out or if i try to go full trottle it cuts out.
well cars or trucks hpi is a good brand for 300 u can get good stuff.i bought my car for 95 bucks runs 65+ mph but its an on road car.
hi i took it to the shop they tuned it but if i put it full rottle it still will not move.
ok so what your saying is it runs fine but has trouble idleing?
does any one have any advice my car start but when i put it full trottle it will not move and the engine make a noise like it is dieing
will the engine life longer, if the setup is too rich?
Is this only for the Savage 25 or is it for any Nitro RC?
what is the difference with a petrol one? what is nitro exactly? cheers
try riching the idle speed needle
does the hpi mt2 g3.0 stay in tune for exemple?
can someone help me? my nitro rc car is a 4wd and the back wheels dont move...the cylinder shaped thingy came off where u put the drive shaft in..when i tighten it it still comes off anyone know what im talking about? the thing that looks like (()) and the drive shaft goes into the middle
I wish i had money to buy a car like this.
