[@atomicspiderpig]

nice instructions i wish i had a 25 like that

[@007foppe]

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

[@seekeroftruth69]

ok where do i set the needle's to begin with? i missed that part

[@AdamDiddy]

Best R/C Nitro tuning video on KZbin I've seen so far. Seen about 20.

[@Pyr0Maniac01]

Im just takin a guess here, is ur car suspension to soft?

[@KodieCollingsGaming]

i wonder how many people's problems were solved at 00:19 "Fill the fuel tank" lol

[@2122nicholas]

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

[@APAP351XY]

hey all when i drive my car it will cut out n stall i have tried various solution but doesnt seem to do much plzzzzz help

[@Master1906]

2:31 his voice breaks lol

[@owens10101]

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 :)

[@jakegwilliam]

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.

[@lankeylively]

@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

[@SamThredder]

i was making reference to the stereotype that canadian people pronounce 'about' and 'out' like 'aboat' and 'oat', respectively. me making this jibe about the canadian accent was fully called for, as you made a jibe about the english accent. there. HBDH stands for hellbent diehard, its my band! i think i prefer HAIRY BASTARDS DO HEAVINESS actually haha and for the record, i went to school until i was 16 like everyone else in england.

[@bighunt08]

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.

[@tylert360]

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.

[@dazzlerby]

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

[@mazpr2025]

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!

[@nichlasz]

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

[@sladeoss]

umm maybe ure piston or sumin is like bent or damaged just say ure engine or as u said when u let throttle of it sounds like a hammer hitting metal maybe because when its fully on its not hurting it but when u let it go it hits somthing? if u r in aus take it to toy world they rock!

[@FunnyHacks]

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. :)

[@noidle22]

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

[@jacobleewalker]

they do tune the enginge..... for the break in process its your job to tune it to how you want

[@RIPje365]

when i start my nitro engine.. it runs a few seconds then it shuts down... any1 knows how comes?! when i stay stationair it runs for like 5-10 secs.. when i hit gas it shuts down imediently.. (sorry for my gramar, not english ;)

[@SamThredder]

its called the english language, learn to speak properly and you might just appreciate other DIALECTS. ever heard that word DIALECT? you probably pronounce the word OUT as if it was OAT. this is called language. english people dont say TOONING.

[@razer1000]

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

[@tittytwister5251]

oh right, errm i dont know then mate if you have bourght it locally, i would take it back and tell them. but if you bourght it on the net i would email them and ask them. sorry mate

[@suzukiholdenman]

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

[@FunnyHacks]

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 :)

[@HUNTYFM]

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

[@locouk]

Here's a request for all you posters, if ya see spam... Hit the spam button under that post!

[@frazeusr]

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

[@dazzlerby]

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.

[@weexen]

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.

[@tittytwister5251]

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.

[@DJ.1001]

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?

[@spiftacu1ar]

I wouldn't get the xl, its just an extended version of the normal savage ss. If you really want it longer, get the savage ss, and then buy an aftermarket tvp set, it will be cheaper and better. Try fastlane machine.

[@tigger00025]

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?

[@HARJ1196]

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 ?

[@tittytwister5251]

lean is more air than fuel and rich is more fuel and less air. you need to turn your high speed needle anti clockwise.

[@BoobyMcDoogle]

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.

[@QWERTYXB]

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?

[@airhogs]

Good video. Thanks for all the tips!

[@tittytwister5251]

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

[@engine2386]

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?

[@Ninjasloth1]

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 !!!

[@mharten]

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?

[@coolestman69]

Sure most cars now go over 35 anyways its a low truck so its probably even capable of going 60.all cars are ready to run but if u buy it new dont forget to break in your engine.

[@extremesoul666]

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.

[@JiMLiTtLe905]

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.

[@tucber37]

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?

[@Nater36]

your backwards bud.. if your engine is hot its too lean, you need to richen it... the richer it is the more smoke it will emit. hopefully you havnt fried your engine yet

[@woody4114]

helpful vid and all BUT this seeing as this video was made by hpi racing, who also make rc cars shouldnt they have tuned them, themselves, before shipping them?? xD lol?

[@starfishingpole]

me and my freind were tuning our rcs and i told him to turn mine an 8th and i was watching and he turned it all the way to the fucking bottom i think he fucked my engine

[@Pyr0Maniac01]

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

[@mattio79]

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

[@spiftacu1ar]

What are you smoking? He asid the engine should always have blue smoke at top speed. FYI: that means its rich. He went lean only for a little bit to show what happens.

[@theMUFF1NZz]

@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.

[@samlakes]

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.

[@sims100uk]

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

[@BFassassin]

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???

[@BostonCeltics147]

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!!!!

[@mitchell8934]

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

[@Triv1umxxx]

I got a Traxxas T-MAX and the clutch burnt out. Cant be bothered to fix it neither. It wasnt that good anyway to be honest. Good for jumping though.

[@norm43920]

I cant get my idle to come down! HELP Please lol.... My thottle trim is set a minium and its still to high. im gonna kill my engin.. Savage X .. Anyone?

[@BostonCeltics147]

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.

[@hoffman999]

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?

[@DJ.1001]

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

[@2122nicholas]

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.

[@2122nicholas]

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.

[@nichlasz]

wait wait wait.. lol....i had a pullstart engine but the pullstarter broke off so i took it off ...if i use a box starter will it work? x.x

[@Bobbyz189]

no you cant it will expolde the engine causing the back place to come off, nothing spectacular but you will not be able to use it again.

[@coolestman69]

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.

[@keithos21]

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.

[@sparts227]

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

[@codehammer10]

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.

[@pillajadud]

hi.,.my engine starts and stalls after about 10 seconds,,and if i hit the throttle it dies straight away, can anyone help? cheers

[@2122nicholas]

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.

[@xRyanwasherex]

He set the engine to lean. That means there is less gas in the engine. You need to richen the fuel so it doesn't ruin your engine.

[@j0mp4m4n]

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

[@norm43920]

GET THE XL !!! Its a BEAST!!! See the Vids?? Towerhobies man google it ;) Peace and Dont waste your money on anything else. :P

[@spiftacu1ar]

my bad, i just finished watching, he says it should ALWAYS have blue smoke, which means both needles are a bit rich, not lean.

[@Nater36]

you dont HAVE to tune it leaner.. just a leaner engine has more power.. to an extent. im betting your leaning it too much?

[@13Anko]

YOU NEED TO DO IT WHEN ITS RUNNING! otherwise you will pump out the fuel, making it very hard to start the engine again.

[@Nek0a]

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?

[@TheEchelon]

Hey, waar woon je dan kan ik een paar shops voor je opnoemen. Je kan ook gwn google gebruiken hé.

[@13Anko]

too low idle speed, if you brake, the carb will close completely, and the engine shuts off, increase idle speed...

[@kylie9832]

yes because the enging has more lubrication so its less likley to get hot and it stops the piston running dry

[@spikerbrad23]

then just tune the high needle but you might want to double check cuz iv nvr heared of a engine with 1 needle

[@Bandicoot803]

Try the following: High speed needle: 3½ turns. Low speed needle: 3 turns. (Based on my KYOSHO GZ15 2,5ccm)

[@kingelmo112]

reset the HSN to 3.5 turns out and the LSN to 1.5-2 turns out, PM your email and i will help you from there

[@Crazylogie]

lol I have a savage also maybe 65Mph maybe not even that fast

[@norm43920]

For A basic Savage X RTR and all you need to run and maintain youll spend 700 TOPS Thats about the base.

[@ritejert]

u use the idle needle if the car moves and your not touching the throttle, thus the name idle needle

[@DJ.1001]

you may need to adjust the throttle linkage for the cutting out. i dont know about the smoke though

[@DJ.1001]

thanks i want on ofroad car that geos at least 35 mph is the firestorm good i think it will do 40mph

[@ThomasCaraccio]

pushing out alot of smokewhen at high speeds just means the hih speed needle could be set too rich

[@MrWhizzo]

Eighty miles an hour, really? Was that in the trunk of your parents car leaving the hobby store?

[@NirvanaRox4Eva]

with idle, do you turn it down, so the wheels dont turn at all? or so they are spinning slowly?

[@bracketracing]

what needle do i need to turn if i still have gas coming out of the exoust please help me

[@2122nicholas]

hi i took it to the shop they tuned it but if i put it full rottle it still will not move.
