How I Tune Nitro Engines

[@greggoju]

I have probably watched every how too Tune a nitro engine Video in the world My opinion is that this video is the best out of all of them No big technical terms that a new person won't understand like me After watching your video I feel confident that I can tune my nitro engine thanks

[@HaggardRC]

That makes me very happy :)

[@lewisclement41]

Love how you explain everything in English. No funny terms just straight to the point. Great vid mate.

[@HaggardRC]

Thanks dude :D

[@Sponge4664]

Love your vids man been binge watching them over the last few days keep up the great work

[@simonakapaddy]

Definitely the best video out there. Can i share this video to my facebook group

[@gregoryhines7]

Thanks mate, you fixed my issue for me. I was having the sluggish take off like that and richened my low speed needle and took care of it. The Traxxas low speed needle "pinch" test had me believing it was fine. 👍

[@HaggardRC]

You're welcome mate I'm glad I helped you! :)

@@HaggardRC so If I richen out the low speed will that get my idle right or what?

You're a legend mate. Looking at the smoke to tune low and high end is so smart and so simple. I can't believe I never thought of it like that! I will try this tomorrow. I find the most confusing thing about tuning is that when the motor cuts out (similar to how you showed on the low speed needle) knowing whether it was cutting out due to rich or lean. However if you just look at the amount of smoke I guess that is your answer. Cool! P.S I also have a HPI rush evo. I have had it for 10 years probably. I love that little car and I can't see it go. I flushed her out with mentholated spirits recently and got it going again. Cheers for the videos and regards from Melbourne Australia.

[@HaggardRC]

Woowwwwwwww thankd for watching man Australia! That's aswsome I hope you got yours running good!

[@superaidenproductions1870]

Thanks rusty I just bought a new nitro engine for my traxxas tmaxx and after I brake it in I will need this, thanks!

[@HaggardRC]

Next I want to get an engine for my Rush Evo :D

[@superaidenproductions1870]

[@nfcbeast]

Thank you so much for this video. I just bought an inexpensive nitro buggy and this information is presented clearly and is invaluable.

[@HaggardRC]

You're most welcome!

[@Joe-DJ]

This is the best video out there on how to tune a nitro engine. Also I’ve been wondering what that needle was that I now know to be the mid-speed needle cause I were confused about what it was. Seriously tho thanks this really helped mate.

I've had loads of them and they do run aways what can I do to stop that and also what do prefer putting battries into the reciver or a hump pack I haven't tried a hump pack I've always put baytries in whats your opinion and the run aways if you can give me advice I would appreciate it thanks

sweet breaking in my inferno as watch....i will definatley use this for tuning cheers haggardrc

[@magnum44pi11]

rc cars with nitro engines are awesome. Battery operated rc cars have their benefits however the sound and smell of the engines is exhilarating and enjoyable

[@HaggardRC]

You got that righ!

[@All-rc804]

Hi thanks for this vid. I just orderd a hpi mt 3.0 (1st nitro)and was wondering how long a full tank lasts on idle for the break in period

[@HaggardRC]

It’ll be about 10-15minutes :)

[@thomashoyle4249]

Do you only have to heat it up when it's cold mate

[@alfiecartwright9655]

Yes

[@mediacontent3991]

No, you should ALWAYS warm engine to 180° to 220° it helps the engine life. It’s highly recommended by all top pro racers as well as manufacturers.

[@HaggardRC]

You're very welcome!

[@downunderdan5132]

Great explanations. I’m in the middle of tuning a replacement carb (Force) on a 1/10 touring car. Still lots of stalling when going from idle to midrange but the ‘pinch’ test seems ok (3sec)? Maybe a fraction too lean still? Also was intermittently hard to turn over on pull start so too lean? Going to look at glow plug condition as well. Cheers from 🇦🇺

[@HaggardRC]

I don’t do the punch test thing myself but I suppose it works, I don’t think it does anything mind you... Get it so it doesn’t hesitate going from tick over to full throttle and you’ll be good :)

[@danielbjorkstrand1474]

Hello! Great video. And very helpful. I am watching this because I just got a HPI that has been sitting for 3 years, is there anything I have to do before starting it up?

[@dazspurs9899]

Just got myself a used 4.6 truggy question...when mine idles the wheels turn fast if I turn the throttle trim down on the transmitter it stalls Same as if I hit the brakes the engine stalls? Thanks in advance 👍🏻

[@HaggardRC]

Hi, there is an adjustment screw on the carb, under the air filter :)

[@dazspurs9899]

@@HaggardRC that makes no difference mate if I fully adjust it when I brake the carb still completely closes and shuts the engine off the Spring isn't taking any of the brake tention for some reason??

@@dazspurs9899 If you turn the adjustment screwin then rhe carb can't physically close. That is how you adjust the tick over.

I have just filmed a video, uploading it now to explain it.

[@tweety18konk]

hi mate, for some reason I can't get my truck rpm to come down properly for whatever reason it just wants to take off all the time. carb gap is set at 1mm. I've tried resetting to factory settings which should be all flush to body but my low speed seems to be way too lean at that setting. even when I adjust the the idle screw it does not seem to make a difference rpm is still high. tried richening low speed rpm still high. any ideas? really starting to rack my brain

[@pauliusz9080]

I have the same car altho i have an r36 big block which in my opinion is a great swap

[@thomashoyle4249]

What car you tuning

[@theGottowatch]

Link to the engine protectors on top of the cooling head? thanks

[@HaggardRC]

Those are cable ties with fuel line on them.

[@lukedeville3658]

Has anyone had a carburettor seize up, if you did how did you un seize it

[@HaggardRC]

WD40, let it soak :)

[@RandoTark]

Hey question for ya! You know when you explain the "take over" coming off RPM's and back to idle? So, u know in first half of video if you gave it a tiny bit of throttle blip after doing that it would bog the idle and then rev back up to normal idle? I assume thats happening because as engine sits there idling it loads up on fuel, then if you dont clear most of it out on throttle blip it bogs down because its still overly rich from fuel load up on prior long idle? ... what can be done to minimize or get rid of it completely? My nitro struggles w/ potentially stalling at that point sometimes.

[@smiff198907]

Hi dude, not related to this brand in the video but I could do with your knowledge and guidance. I’ve just bought a traxxas slash 3.3 and upon the break in procedure, the car will not idle and accelerates upon starting. I’ve adjusted the linkage, set the idle screw to 1mm gap, played with trim etc with no joy. As per the manual it states no to make any alterations to hsn/lsn until a 6 tank beak in procedure, do you have any recommendations? You’ve gotten yourself a new subby 🙂

[@HaggardRC]

Make sure the air flow and fuel flow is free, then play with the needles dude

[@elliottlinay5464]

Hi my rc nitro hpi evo rush keeps bogging on full throttle y.

[@blueovalcraig]

Great informative video rusty. Can I just ask though, I’ve seen loads of nitro engines with the cable ties through the head. What does that do? My Savage has given me nothing but problems with the spur gear melting on tickover but I think there was problems with the clutch shoes. I’ve replaced all that and just waiting on some half decent weather to get out with it and see how it goes. I’ve asked for a trophy Truggy for my 35th birthday next month so we’ll see what I get lol

[@HaggardRC]

Haha lets hope you get one! The cable ties with fuel tubes on them are meant to stop your engine getting scratched if you flip it over without a shell on or if your shell doesn't cover the engine. I do it because I like the look mainly though.

[@joshfisher1276]

Thanks for this. I had electric cars some 30 years ago grasshopper lunchbox hotshot etc. Thought I would give the nitro a blast I bought 2nd hand which is probably not the best idea as I have picked up some else's nitro and starting from there, nevertheless with a lot of head scratching and patience I have a runner and now looking at tuning it up (bit at a time mind). I have watched and will probably watch again and again as you seem to explain it all it simple no Bobby bullshit terms. Thanks. On a side note did you or (probably) still do cb radio stuff? If so 73's!

[@michaelinzitari]

Hahaha so many mistakes in this video. You congratulate yourself on having a double idle. Which should be eliminated. You tune the low speed needle first, which is second. You tell beginners to touch the mid speed needle. You tune the high speed after the low which should be first. And you fail to talk about the idle gap which is critical to balance with the low speed. This is FAR from the best tuning video on the internet.
