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
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.
@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.
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.
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!
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.
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.
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.
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.
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. :)
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
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.
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
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!!!!
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.
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.
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
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?
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 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?
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???
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?
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 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.
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?
i have a asnmann 1/8 nitro buggy i have tuned it and is running but when i stopand it starts to tick over and about 5 to 10 sec later it stops why is this plzzzz post back i wood like to get it right thank u
Best R/C Nitro tuning video on CZcams I've seen so far. Seen about 20.
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
I just bought a traxxas s-maxx and this helped alot thanks hpi!!
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.

an excellent help. better than the manual that came with my truck.
Really really good tuning video. best i have seen
Good video. Thanks for all the tips!
this video is great, recommend to all the nitro nuts in the world
Fantastic video mate, really good quality production and instruction mate thanks.
Thats Cred, you should get an award
he isnt wrong. you are, this is the best and only good way
@iamthewalrus026

thanks mate.. really helped.. my car was begining to do me head in... Cheers
yes because the enging has more lubrication so its less likley to get hot and it stops the piston running dry
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.
verry helpfull like the "anticlockwise"
nice instructions i wish i had a 25 like that
@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.
you may need to adjust the throttle linkage for the cutting out. i dont know about the smoke though
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.

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
fantastic video!
they do tune the enginge..... for the break in process
its your job to tune it to how you want
thx man this helped alot... i really needed this THX
MAN... leep posting em..
excellent video.

turn the idle needle down so that it doesnt move at standstill and just enough to keep the engine running at idle.
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.

adjust the idle. its a small screw on the carburater
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.

That was helpful. Thanks.
good video it helped a lot. what kind of truck is that big foot??
@CJLongoproduction09 Some older cheaper cars do not have an low speed.
Try the following:
High speed needle: 3½ turns.
Low speed needle: 3 turns.
(Based on my KYOSHO GZ15 2,5ccm)
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!!!!
Make your idle speed somewhat higer by turning the little screw in..
GOOOOOOOOOOOOOOOOOOOOOOOOOOD !!! Swietne
I was looking for this :p
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
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.
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.
Low speed. But the needles are set from the factory for optimum break in air/fuel ratio.
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.
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 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
then just tune the high needle but you might want to double check cuz iv nvr heared of a engine with 1 needle
thanks i want on ofroad car that geos at least 35 mph
is the firestorm good i think it will do 40mph
u use the idle needle if the car moves and your not touching the throttle, thus the name idle needle
with idle, do you turn it down, so the wheels dont turn at all? or so they are spinning slowly?
the 3rd are the idle needle
thank you very much
the front wheel cups just might be loose. check if you already havrnt returnrd it yet.
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?

thanks
what needle do i need to turn if i still have gas coming out of the exoust please help me
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?
newbie question: does smaller engine have to be retuned more often than bigger ones?
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?
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
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?
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 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?
hey what happens if the smoke is not blue but red or a different color?
try riching the idle speed needle
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 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???
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
ok where do i set the needle's to begin with? i missed that part
yes it works wit all cars
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 ?
will the engine life longer, if the setup is too rich?
was it blowing alot of blue smoke and running hot? let me know how it turns out thanks
thx heaps. and that thing is a beast, lol.
Thanks this is realy helpfull ;)
what is the difference with a petrol one? what is nitro exactly? cheers
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.

hi i took it to the shop they tuned it but if i put it full rottle it still will not move.
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.
ok so what your saying is it runs fine but has trouble idleing?
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.
my idle ga is about 2 mm should i lean it out
What is the model of this radio controller?
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.
Is this only for the Savage 25 or is it for any Nitro RC?
Look at the video response above!
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?
i have a asnmann 1/8 nitro buggy i have tuned it and is running but when i stopand it starts to tick over and about 5 to 10 sec later it stops why is this plzzzz post back i wood like to get it right thank u
