I know I'm late, but this is the most informative video I have watched on this subject!
8 years later and still 1 of the best tuning video's
Thanks :)
Thank you for clarifying the use of these adjustments. I'm new to nitro RC cars and have one for my grandson. He is eager to start and run it. The hobby shops charge a fee to help with these matters. Your advice is extremely helpful and valuable.
Your tuning videos were... het..hem... are, 2nd to none! Hope your doing great! 👍
mine has lasted 6 years and on average i use it once a week and the engine is still running strong
What kind ?
@@mackellarboy7 broski its been 8 years
Yo you still alive
@@freddieparrydrums lmao

Highly informative and easy to understand instructions. TH-cam gold!🤘💪
Mine has lasted 16 years now and still running strong!
I have followed all of your advice, very informative videos thank you for posting. I have a menace .21 and due to high performance i lost control and cartwheeled about 40 feet at 70mph lol
Lovely video. That explains a lot and I love that you done it live.
I love your tuneing video I bought a tmaxx and spent three hours trying to tune it then watched your video and damn five minutes it was great I only will watch your videos for tuneing
i love the way you explain things your the only one on you tube i watch to understand tunning
Going to be brutal… initial thoughts was oh jeebus what is this kid going to teach me.
Best how to video i found, you do it as to you tell it! Awesome!!
This guy is very knowledgeable and articulate. Also very willing to share what he knows. Thank you
No problem :)
nice video man i have watched this millions of times.
Awesome video! Have been having trouble with mine after it’s been sitting for some time. Thanks for the help
Thank you do much. I recently got into nitro from electric and this video made so much sense. Thank you and 2 thumbs up on this video. Oh and I just had to subscribe
Very great information mate; I am a beginner to nitro so I have a lot to learn
Your videos are very helpful, very clear and most of all, go right into the subject, thanks
Glad they help!
Nice video man!! Im new to this hobby and dont want to blow my engine but wit your guidance in dis video I dont think that is possible! Nice Work Again and Thankz
this advice helped me heaps, cheers dude.
No worries thanks for watching
Bro this was very helpful, thanks alot. Before this is didnt even know about the idle adjustment needle
just got a Revo 3.3 used and I found that had to set the LSN then the HSN and after I got the HSN correct I had to readjust the LSN for idle rpm point. after that the thing pops right off every time. worm or cold. the guy I got it from had the HSN 3x richer then it should have been and the idle and throttle control set way to high just to keep it running. what a goof
I was given a traxxas revo and a traxxas slayer a few weeks ago foc. They haven't been ran in a couple of years. I found your vid very helpful and have the slayer running sweet. Kudos, man 👍🏻
Very cool!
your a god send ! thanks for sharing your knowledge .
Very helpful thank you JT
straight to the point good stuff !!!!
best.voice.ever. OF ALL TIME.
Great info, thanks dude.
another good one JT...keep it up..
I’m literally one week into nitro not even and this has helped so much!, I still have blue smoke at the lower so just need to get that adjusted
Glad it helps :) Remember that blue smoke on a Nitro is good though.
@@TheRCBiker Jason could you please tell me how that battery work? It look like 11.v
hi there i'm marlon from the philippines, i have a problem on my rc car before dont know how to get it back to factory settings. but when i'm watching all of your videos repeatedly its help me a lot by telling there that what's the used of LSN, HSN and IDLE.i just follow step by step till i get it done. im using hsp bazooka buggy nitro. thank again and keep making videos for other models.
Ur videos are super detailed. I like it a lot. Keep it up. Also I noticed how come u do a lot of tuning vids?
Great video mate. Very informative. Thanks
No worries Thanks for watching :)
Awesome video! God bless you bro!
You're welcome :)
hey JT, good vids man, lots of help... love ur work. i have a question... my nitro engine chews glow plugs. on a good day, ill use 1 glow plug per tank of nitro.. pretty crazy. do u know if a rich/lean running engine will cause the element in the glow plug to get deformed and look like its been sucked or pushed back into the plug itself? hard to picture i know, if u want a picture i can link/upload an example of 1 of my glow plugs. thanks heaps and keep up the useful nitro tips!
I am watching this video so many times just so that I can remember all if it. My buggy usually Boggs down at half throttle, usually shuts off.
You saved my hpi savage xl octane thanks
Earned a sub
IT SOUNDS QUICK AND SNAPPY NICE !!!
You help me really well in low speed lean and rich video
If my engine is revving to high right away, and running off when I start it which screw should I turn and in which direction
Very helpful and well explained
Glad it was helpful!
what way do i turn it when i want to increase the speed of my car, i have a revo 3.3. left or right?
Nice vid!!!
It takes time :) stick with it. You'll get there
Ik this is was made a while ago but I have a problem with my metal spur gears constantly stripping out on my tornado s30 do you think you can help me?
I'm new to nitro and my truck just would not work. Wouldn't start. I got it started but run and sounded all wrong. after watching this short video I think Im nearly there . a massive thank you. good job
Hi there , I have the basher sabertooth truggy with .28 engine and I'm having trouble tuning the LSN , it blows heaps of smoke so I lean it 1/8th turn and the idle just gets so out of wack , I try and adjust the idle every turn until the acceleration was really good but the revs hang after throttle , I can't seem to get the idle right ?
I saw in one of your vids you briefly mention something to stop the RC from running away, can you tell me how to stop this?
thanks for your videos.. i have mgt 8.0..and the engine wont star at all.. i think there's no fuel going into the engine,cause plug is good. dont know what to do. help me please.
Where did you get your glow starter with the Lipo battery from and what size Lipo
whats up JT, i have a problem with the start up,any tips how to set the carborator?
and another think,iam like pulling say 50 times to get the first start up and when i remotely trothle it shuts off.....why?
Good video!
will you make a video on the idle speed needle ,and how to tune it.
hi I'm new to this is 25% fuel ok with this engine? thanks in advance love the videos been learning a lot thanks mate
Well done
What needle helps start your nitro car easier because my nitro buggy does nit start to easy
I bougth a Carson vírus. When i vive power the car runs nicelly but When i break it turns off. Wich needle do i have to set? Thanks
Many thanks :)
If my car bogs out when on full throttle do I need to go clockwise or anticlockwise
Hi, in the video I know you use .18 Force engine, I just got one too, but I mass up the setting of low speed niddle, do you still remmeber what is factory setting for this engine ? my car runs for few times during break in , become harder and harder to get it to start. then I play around the LSN without write it done the setting, pls help.
thanks your vid helped me out my bullet 3.0 mt is running much better
hello there, am a beginner to the nitro rc world, bought this buggy and after going through the break in process, notice a screw came off the engine, not the low,high or idle but a thin screw just below the idle, any advice on how to put it back. seems loose, any adjustments required? ...thank you
Novarossi beat 5 port"
Very nice vid. It would be nice if you make a vid, wich shows the bad hsn, and lsn setups both the lean and the rich sets. Because the car you go with is almost have the right tune but most of us how try to tune have very wrong sets. So it would be more helpfull i think. Thx.
Do you have to do this everytime? My Nitro car always turns off when i acelerate a lot.
Hey..im a fan. I just got a traxxas nitro rustler and im using your vids once I complete my break in. I just wasnt sure what that ideal idle sound was suppose to be as you set the idle needle. Do you want it as lean as possible without it dying? Same clockwise to lean counter clockwise to richen applies on idle needle? Thanks
the cogs that turn the drive shaft on the engine are they so post to move back and fourth
Hi um I have a question. Well I just got into the nitro hobby and got a 1/8 exceed madbeast. Well the first run I got it to go, but the second run(next day) it went full throttle anf breaks were almost useless. Luckily we caught it but is that perhaps due to the tuning? And btw it is 2 speed transmission car.
can someone help i have a exceed nitro forza with .18 motor just bought when trying to start for first time it"s RTR , fuel comes out of exhaust pipe what am i doing wrong any suggestions
What about VP PowerMaster fuel? I run a T-Maxx 2.5 with the original TRX2.5 on VP master basher 20% nitro with 14% synthetic/castor blend. Is that too much oil? Also I use 2 different exhaust systems. My stock plastic tuned exhaust system and a RD Logics twin outlet rear exhaust (RDL61515P). I broke it in (had it taken to HobbySports in Portage, MI TWICE since it wasn't shifting into 2nd gear at all and had it tuned on Cooper's 20% nitro [didn't say the oil content/package but it was hot pink in color] and ran it 1 gallon on Fantom Performance Blend 20% nitro (strawberry colored & don't know the oil content/package wither), 2nd gallon was Traxxas 20% nitro (blue colored), my third gallon, which I'm on now is the VP PowerMaster's Master Basher 20% with 14% synthetic/castor package purple colored. My engine has hit 405 degrees FAHRENHEIT without the body with the dual exhaust installed using this fuel. It runs best @ 290-320 degrees with the stock plastic exhaust system installed body on or off when in perfect tune. The engine still runs, glow plug is still intact, and piston/sleeve feels plenty tight (more than tight enough to pinch my fingers after performing after run maintenance). What's wrong with it? This is my first Nitro model (which I plan on installing a TRX 3.3 in once the 2.5 gives up or I run out of fuel).
My rc keeps cutting out when I accelerate and it takes ages to start is the low speed needle to lean or rich
Do you have a tutorial on how to adjust the brakes?
Your the man !
Thanks mate.
great video mate however I need some more info and you may be the man for the job.
I have a ftx frenzy bought from a friend that broke it in correctly but then messed the carb settings up completely. in now runs like a bag of spanners if at all. I have the manufactures instructions however they don't tell you the factory settings for any of the needles. I am happy with the location of the high speed needle and the low speed needle. the engine bogs down and quits just after idle????? any ideas
My Sandmaster mk2 as far as i can see has no low end niddle . The high needle is all the way down to stop. it starts but if u turn it too much counterclockwise it floods out. Also my sandmaster mk2 don't move when u give it the gas. wondering if my differential is out. 1 sode is tight otherside is loose and turning when u hold it either by hand or with ellen wrench. u turn the gear by hand the both move. put it on the ground car smokes and standing still. got nobbie tires on back
well done, really good video,,:) and remember about 50% of your cooling comes from the the air/fuel mix. So if it runs lean, it gets too hot and the motor wont like it;) or even die:(.. have fun:)
Is he tuning it 1/8th of a turn counterclockwise from the default settings?
Awsome man what kind of car is this?
Hi mate I've just got a hyper 7 tq sport mac28 do you think Tharp a good car? Only thing is I can't seem to get it started well to idle! Do you have any recommendations? Also do you have any cars for sale? I've put a short vid of a small bashing on my petrol hummer on my channel if you want to check it out?
hi guys, i have a Traxxas t-maxx 3.3 engine and i want to know if i could run it on Factory settings on LSP? if i do that...do i need a lil adjustments to keep it running on that settings. thanks in advance.
The HSN controls air and fuel mix from Partial (around half) to full throttle. LSN is idle speeds and low speed driving
TheRCBiker hi, I have a thunder tiger pro 15 engine. It’s old but starts fine. It just gets way too hot to the point it loses power and cuts off at about 2 min of running it. It’s so hot water boils on the engine top. Do you have any recommendations on what’s wrong? Thanks
Hey wat do i do if my rc car will start qith the igniter and me pushing the throttle but when i take the igniter out and let go of the throttle it dies .... Oh and my idle speed screw is all the way in
you shown show in both adjustments extreme situations in tunning ! what happens in each case!
Air and fuel are two different things. Which one are you asking about?
to increase air fuel which way do i turn the needle? left or right?
If when im driving my nitro Tmaxx Or revo an when ez start wire falls off that connects to glow plug An car shuts off that means car isn’t tuned right
hi mate in some of your videos i noticed you were still using the AM radio system. Can i ask why you are since after recently switching to 2.4ghz i would only use AM while waiting to set the car up with 2.4ghz
Does your car have a higher pitched sound due to the engine being only a .18?
where can i get one of those glow plug igniters in australia?
Awesome info just put new picco .28 on my mgt 4.6 and don't want to ruin it I was also told not put hand Helton stater on until engine is broke in is this true
Hand held starter I ment
I have nanda nrt 3 pro truggy. Can anybody share the rich settings with me. I am a beginner. After I've taken 3 laps I am not sure why does the oil come out from exhaust.
hi, when l start mine the wheels go round please what could it be, thanks
I was always taught to tune the LSN first.
Using a pinch test, engine should run 3-5 seconds max.
Only then can you tune the HSN.
What about tuning a RC drag car engine???im new to sport need help tuning.
what would cause a nitro volcano s30 not to start could that possibly be a bad glow plug or what?
Hey good show but I have a Team Associated nitro MG monster truck it will start but shuts off once I touch the throttle the truck has never ran the buyer gave it to me when he could not even start it.
I know have a sledge hammer s50 it's got low high and a mix metering screw you tune hi and low then a just your mix screw is 8.2cc engine, you should do one on a 3 screw engine with a mix screw
Ok uve got an old tmaxx 2.5 and when I give it full throttle it boggs down and stalls out. Help me out, thanks
