Traxxas setup 18 of 21 - Tuning your Engine

[@elmakednos]

Nice performance.I am tuning my tamiya ferrari too.I have made today a very extended service but I have to make some more adjustments.Not all people test engines at 22:30!!I think I am an r/c crazy!!!

[@pablosgarage707]

very helpful got my nitro rustler running amazing

[@yoyoman2k1]

well if it comes with the tmaxx backplate then you can use the traxxas ez start system other wise you will have to get the pull start or a shaft starter that fits the particular plate it comes with.

[@TheRCBiker]

yes they are ok at high temp

[@yoyoman2k1]

yes you can stretch it out over a few days and yes it is ok to do after run maintenance on the engine before fully broken in.

[@initiatededdeano]

@RyanRNewberg already have done this cant find any leaks,, maybe from around th slider on carb but it has no seals to replace so I think thats ok, I still have smoke even at high speed and it doesnt stall or anything so maybe its ok I just need to let it cool for a while... seems to cool very quickly anyway.. I have anouther brand new 3.3 too so I will just use it til it blows lol..

[@mountainbiker1881]

if you have to tune the engine how would you know if you need to tune the high speed needle or the low speed needle? once you know that how would you know if you need to lean or richen the mixture? how do you tell if you have to tune the engine?

[@rootsragga11]

@HDxMOD you should try to "repinch" the cilynder ,it worked for me . search youtube for "repinch nitro engine" and you will probably find instructions :) good luck

[@rocrfella]

Which needle do you turn to get it into VTEC mode?

[@sschriver110]

and is it ok to let it run out of fuel while driving the rc car after break in any anwser will be great thanks

[@sschriver110]

cause it says when you watch tank 1 it says if you run out of fuel it will run more lean which is not good and the engine temp will go up if you run out of fuel but idk if that counts after you break it in or not

[@yoyoman2k1]

those work good to if thats what you want to use. i prefer a temp gun. it just depends on the person

[@plug007]

It might be the trottle trim and servo's, its no big problem.

[@sschriver110]

k thanks but would it do damage to the rc car cause i have ran out of nitro before while driving it and when i drive the car i normally drive it a little rich

[@roastbeef150]

If it is what is the base setting for the .15, and how do you get to the lsn without taking off the fuel tank

[@XaircraftX]

do you have to use traxxas glow plugs on youtr truck? or you can use any other glow plugs?

[@jmey107]

i have my trx 3.3 engine very rich and it still runs at 270 to 290 degrees, i have heard some people say that the 3.3 can run pretty hot and still be ok

[@isaipedeoza7274]

Open the low speed needle more

[@mountainbiker1881]

ok, so if your engine is running to hot or too cold do u richen or lean the high speed needle or the low speed needle?

[@kullyl]

hello, i have just put a new clutch in my traxxas t-maxx 3.3 and when i drive it, it seems to be slipping. does it just need to be worn in?

[@iceking123kitty]

hey i have a question!! when they say to turn the high speed needle in turns, do they mean (like on a clock) from 12 o'clock to 12 o'clock (all the way around) or from 12 to 6 o'clock for 1 turn on the high speed?

[@Ninjasloth1]

try replacing the glow plug, or try the low speed screw prob richen it.

[@yoyoman2k1]

even after you break it in you shouldn't let it run out of gas until your done running for the day cause it does run leaner when the tank gets emptier so you want to check it and fill it often.

[@carslovr222]

i need help, im new to the rc nitro world and i just got a used Exceed razor 1/8 scale and the old owner hasnt used it in like a month and when i turned it on the idle was so damn high!!!!!!!! then after like 2 minutes of idling at high revs it just shut off immediately, withought going to a lower rev.

[@thenomadrhodes]

awesome videos thank you..

[@3starRC]

Thanks heaps, just learning how to use these

[@wallawoo54]

my t-maxx 3.3 has a sudden loss of power during acceleration, but has a good smoke trail, any suggestions?

[@eember]

hi have a quetion my nitro car drop power when acceleration. but in full trottle only.tnx

[@lopez430]

@VideoGamePlayer12 got my s maxx 3.3 and dont regret a thing about going nitro. yes maintainence is alot more complicated, but well worth it.

[@burtonrider8907]

okay could someone help me please. I bought a nitro pullstart r/c car a could days ago. my ripcord broke the day I bought it..... did I pull to hard? how hard is it to snap the pullstart string? I snapped it... called the ocmpany their sending me a new. what can I do to prevent it from happening next time? Please respond...

[@sschriver110]

what do u need to do to turn the idle screw down

[@cambo91]

I thought you are suppose to richen on hot days and lean motor out on cooler days?

[@Smit1730]

Camboooooo if the air is hot, it’s less dense, meaning there is less oxygen per given amount, which means you need less fuel so it’s not running too rich. On cold days, the air is more dense, so there’s more oxygen in that same given amount. This would make the engine run lean as there is more oxygen in the combustion chamber than would be on a hot day. Given the same high and low speed settings, more oxygen in the cold air would mean its running lean when compared to the hot air with less oxygen..... which would be more rich.

[@Dieselboy805]

how much will it cost for a tune at a local hobbystore?

[@initiatededdeano]

anyone help.... I just ran inn my revo 3.3... I have onboard temp.. after high speed runs it reads 330f which is way to hot, it is richer then break inn settings still? using 20% byron fuel... also will not wheelie..... any ideas... PS I understand that the leaner yo run it the faster it is (to a point) but I cant lean it out else it over heats....... so I dont know....

[@carslovr222]

then we took it to the hobby shop and they tuned it and they said it runs fine but it just overheats so i richened bot the HSN and LSN 1 more turn than the hobby shop guys did and were gonna test it out. Ill tell you the results.

[@carslovr222]

when it happened it wouldnt start anymore so we thought the piston and sleeve welded each other with all the heat from the engine but we got lucky cus it started 2 days later and we tuned it so the idle revs wouldnt be so high (idle screw) so now it idles perfectly and stays on at idle but when i give it just a bit of throttle it just shuts off, we got lucky one time and we were able to make it run for five seconds but then we hit the brake and it shut off. out of characters.

[@2122nicholas]

ADVICE: when i start my truck it idles fine but when i press the gas the truck will like barly even move please help

[@home91011]

hi i have a s maxx 2.5 and fule will not go thro and i plue in to th e topb to prime the emgen and i de fuded and it still well not start can you help :!

[@roastbeef150]

In the vid. your tuning a 2.5, is tuning a .15 the same?

[@sschriver110]

why does the idle speed even go up cause one day i started my nito rustler and the idle speed was fast i know how to fix it i am just wondering why its doing it

[@NotTheLarryDavid]

shut off: increase the low speed needle so that the carburator is slightly opened when breaking. drink like mad: decrease the fuel injection on the high speed needle (will drink less and have greater speed)

[@jafyjamie17]

Does this technique applie to virtually all nitro monsters and buggies?

[@sparto888]

Its your idle is too high or maybe your servo may be sticking

[@2122nicholas]

can any one help me i have nitro monseter truck it starts but if i do not drive it it will cut out or if i hold the break it cuts out.

[@yoyoman2k1]

its good to have a temp gun cause you dont want your engine going over 270 or it could damage your engine. you want your engine at about 245-250 its ideal temp for those engines.

[@kingelmo112]

On my car, a .27 engine, 3.5 on HSN and 1.5 on LSN, then tune it from there.

[@yoyoman2k1]

sounds like your low speed needle is to rich so your car wont stay running or idle. i would try to adjust that needle and start it up it should work then

[@yoyoman2k1]

you can use any brand glow plug you want. check out my other videos about how to read your glow plug

[@kalemimak7]

great video,, thanks...

[@yoyoman2k1]

that would be the high speed needle that you need to adjust.

[@yoyoman2k1]

use the one you like the best....as for me i hate pull start so any ez start system i like.

[@iceking123kitty]

hey i dont no if you fixed ur truck problem but it sounds like its too lean...

[@508ZACK]

thank for the help

[@XaircraftX]

is your engine or truck new? if it is you just have to let the engine get loose and it eventualy get into place and stop doing that.. =-)

[@MaquinasDePalomitas]

Very helpfull!

[@yoyoman2k1]

they say 1/8th turn which is like from 12 to 1 which is not even a quarter of a turn on the high speed needle.

[@qw1as1er1df4]

does it overheat??

[@2122nicholas]

thank you

[@yoyoman2k1]

now you have to adjust your high speed needle and your low speed/idle needle which are the same needle. your idle should run fast when your running it and then when you come to a stop your idle should slow to low rpm in a few seconds and when you pinch your fuel line your car should speed up for 3 seconds then shut down if it speeds up longer then a few seconds when you pinch the fuel line before it shuts down your idle is to rich

[@gforce_117]

Cool it's just if I adjust the low speed needle it effects my idle speed and wants to creep away. Then when I adjust that I take off an it almost quits because of to much fuel. I have the 3.3 In my t-maxx. The High speed needle is ez to tune

[@yoyoman2k1]

yes it does

[@yoyoman2k1]

ok your idle adjustment is to lean and needs to be richened in order to slow down the idle the low speed needle would be fine were it is

[@based_will]

@lopez430 Sounds way cooler too. To bad i have crabby old people for neighbors who made motorized scooters illigal in our neighborhood.

[@norm43920]

um a screw driver lol.. Unless you have the savage X The trim is on the remote ;)

[@based_will]

wow... glad i went with electric

[@bestamerica]

i have a new stampede by traxxas..i like a battery powered is the best than gas powered

[@eastcoast78]

@HDxMOD what you mean? not in tune? broken/croaked.? Theres many ways a engine can be F'ed up.. ;0)

[@AMHMAN22]

yep

[@yoyoman2k1]

yes

[@evilmuscle]

at least all these guys harc cars that run i have a madfire and it dont do anything and not even 10 minutes of run time on it. i will get a traxxas real soon though

[@chickensquad94]

@MrSavageXss dam straight

[@sschriver110]

k thanks

[@lopez430]

@VideoGamePlayer12 haha whatt? really that sucks. one of my next door neighbors are dicks and took my old man to court for partys n shit. so first day i get it im doing wheelies in his grass, running over his plants.. just broke it in yesterday and now it runs like a champ.

[@turbozor]

lol my pro .15 is so simple lol no fancy stuff

[@yoyoman2k1]

too hot you richen, too cold you lean want to find the point that works in between.

[@Mikitsubizunizu]

Slow the idle speed.

[@GixxerGuy]

lol.....adjust low speed needle...duhh

[@Dudemanified]

@Dieselboy805 20 bucks for me

[@AnThOnYrox8]

to lean richen it abit

[@fastandfurioustokyo]

he could fry his engine and lose a lot of compration

[@adb140275]

NO!

[@Mediarahan003]

When I give my car throttle after letting it idle and warm up it boggs and dies. I just replaced fuel lines. is this a glowplug problem or an air filter problem or both?

[@moralllo]

can some 1 help me with my mosnter MT, i can start it perfect, but once i rev it to move it just instantly blurs out, any help is gr8

[@kreizmann2943]

very helpful!!!!

[@AMHMAN22]

yep

[@yoyoman2k1]

yes
