best nitro tuning vid ever

@mugeshraj6478 2 года назад

💯

@joshuajkoplin 6 месяцев назад

This. THIS is the video. Nothing left to change. No “close enough” solid, methodical and a step by step proceed. Giving all the “why’s” bang on video, man. Thank you. We have the same brain. Yours just has this info that mine didn’t. Very understandable.

@roblafear 3 года назад

Thank you thank you thank you. I have been in this hobby for 11 years and wasn’t able to get a race tune on a vehicle until seeing this video. Thank you for your work

@wolf16731 3 года назад

After running these things for 12 years, I think you just shown me the easiest way to tune that I had never heard of. Its so logically sound that I'm going to try it out right after this.

@wolf16731 Год назад

It's been two years so I figured I would check in. I did follow through and I can say without a doubt that this video definitely improved my performance at the track. I rarely, if ever, flame out in a race and the car just works. The brakes are never trying to overstep the engine or vice versa. The engine always reliably comes back to idle and the brakes don't stall it. Thank you for this video!!

@Chris-0113 Год назад

@@wolf16731Awesome. Thanks so much for coming back for an update! 👍

@MrLilChilly 3 года назад

Touche, I couldn't have explained engine tuning any more thoroughly. I had a big bag of popcorn 🍿 during this. 2 👍👍 up. You have a bright future in RC youtube ahead of you🏎💨💯💪💪👊👊👍👍

@alexandrenevraumont1716 3 года назад

From far the best video ever on how to tune a RC nitro engine, just brilliant !

@broodro0ster 3 года назад

You delivered as expected! This video blows all other tuning videos away. I love how start with the theory (very good visuals of the engine and carb btw) and then move on the practically side of tuning. This is a must see for everyone who is still struggling with tuning. Also the production of the video is very good. 10/10! I’m looking forward to the next one.

@Brennen_Nisporic 3 года назад

By far the most comprehensive video on nitro engine tuning I’ve ever seen. This video is going to help so many people learn how to properly tune their nitro engine. Great work 👍

@darrenjohnston3722 3 года назад

Great video, the best there is out there on race engine tuning.

@invisiblespeedrc 3 года назад

You know what to do then! Share! Thank you

@samuelkcharlz7804 2 года назад

The best I have seen I'll remain here, I owned Kyoshos since 1990 and very happy with presentation, it took me a lifetime to learn this and here I am in an open book on carb tune.. your explainatons makes it a kiss in hand...I commend n recommend u jr.. keep up the good work.💪💪

@GRC-Racing Год назад

This is one of the best RC videos on RU-vid, period. Thanks, JQ. Amazing video, I learned a lot.

@Mrlegodj 3 года назад

Been tuning for over 20 years, This video explains it perfect

@mikeiz6944 3 года назад

Possibly the best tutorial video ever in tuning a motor. That double idle as haunted me for years, looking forward to trying your method out. I wanted to take a minute and say "thanks" and well done on the vids. The editing and the funny moments make for an enjoyable experience and learn something along the way. Great work! Subscribed too.

@NathanStorer-RC 3 года назад

A rather long video, but extremely helpful. A lot of other videos I've seen on the topic seem to "gloss over" the specifics. Being able to see the change in comparison to good/lean/rich is super helpful. I've not purchased a nitro before, but this certainly is helping me get the confidence I need to make the leap into nitro. Can't thank you enough!

@HONK3Y Год назад

Thanks for taking the time to share the knowledge. Nitro rc cars are almost rare in 2023. I walk into local hobby shops with my vintage traxxas or even my ofna racing buggy and they look at me like Im crazy. They dont even have any nitro for sale. They try to push electric on me. They have little to NO knowledge of nitro. Wont even look up parts for me half the time. Whats funny is as soon as I fire one up. Everyone in the store comes running. They always want to see them run. Was tuning my traxxas earlier this week I had an entire construction crew of guys hooting and hollering. I let them drive it around a bit and they looked like kids at xmas.

@factoryrollracing3847 3 года назад

I think this video saved me from a more than a few screw ups over my first full nitro season, thanks!

@michaelvesely 3 года назад

This is by far the most detailed explanation on how to tune an engine. There is a lot here but my biggest takeaway was the idle gap and how to set it. Keep the content coming please!

@davelowets 2 года назад

Absolutely! The idle gap makes ALL the difference in getting the tune right on.

@XSspeeds 3 года назад

For measuring the idle gap: The shank end (the part that goes in the drill chuck) of a precision drill bit or what are called 'pin gauges' would be an easier tool to use. They are round and fit in that space more easily. The pin gauges would most likely be more expensive, and are precision measuring tools machinists use for gauging similar situations. The precision drill bits come in small sets and cane be found at many places dealing with hobbies and crafts. Just measure the shank end of the bit with you calipers ( most of the time the shank is slightly smaller than the labeled drill bit size )

@isiaht.9051 3 года назад

This video was actually really helpful, and I like how he broke it down in many different ways and examples. The open carberator example put things into a better perspective. Thanks for making the video

@josephgreer9693 Год назад

Best nitro tuning video out there, answered all issues you could have tuning a nitro engine.

@claytonha7898 3 года назад

Thank you JQ, When I got Into this hobby 12 years ago I went with electric buggy’s because when I would go to the tracks, nitro vehicles were always having trouble starting, running and finishing. After a couple hours and 4-5 battery packs later when I’m leaving, I’d see the nitro guys still trying to tune and run their vehicles...SMH. Your detailed explanation is something I get and understand, I now have a better understanding and will look at trying out a nitro buggy... again Thank you!!

@wanderer260 3 года назад

Makes me want to buy a JQ now , yeah why not 🤘🏽. Awesome video and love what you’re doing .

@Jaybo454 3 года назад

Thank you so much for putting the time and effort into this video. I got my first nitro 14 years ago as a kid, didn't really understand it. Ran it into several car tires and destroyed it. During the pandemic, I found it in my parents basement when I was visiting and decided to rebuild it. I am having to learn everything and this video is finally helping me understand tuning like never before. This is my second time watching this currently, so thanks mate!

@spraym88 Год назад

Absolutely GENIUS! I not only watched every single portion of these videos broken down, i just watched this entire video fully! So awesome and i can't wait to get my Truggy fired up & Tune my Team Orion engine tuned

@jukiranks 3 года назад

Bro this is one of the best rc vids I've seen. More please 💯

@StewartKumar 3 года назад

Absolutely awesome explanation! Really takes the guesswork out of tuning. Makes me wanna go burn some nitro and wake the neighbors :) Keep up the great work, looking forward to more.

@JG0en187 7 месяцев назад

I always watch the video when I jump back into nitro rcs. Im one of those guys who doesn't have a dedicated hobby I'm all over the place lol This detailed video is so helpful I just jump to the parts I need to review.

@isaiahfurrow7414 Год назад

This will be helpful when I get to race a Nitro for my first time next weekend... less than 10 days to get up to speed and make this 2wd gas truck go BRAAAAAP!!! Thanks again for your content.

@Teammugenseikeracing 3 года назад

Thank you JQ for putting together a very professional video together with some laughter in it. Normally the videos I have seen on how to tune a motor you can’t hear 👂 the person. Every detail you explained really help me understand in detail how the motor works. What I need to listen to and what the motor is doing. A+. Keep the videos coming. For 5000 subscribers put out a JQ black ED kit

This is the definitive guide to tuning nitro engines. I can't believe I've been looking at this for free... Thanks for all the effort you've put on making it, you did a great job.

@invisiblespeedrc 3 года назад

Neither can I! Maybe you can get the invisible seed book and match your car setup to your engine tune? invisiblespeed.net

@vasilismalemis8640 3 года назад

For someone who has struggled a lot with the tuning, this video is the light. Thanks man. There's no other video like that in the planet. For sure..You did the difference. Thanks..

@benpetz6816 3 года назад

Havent Had Time to watch the Full length yet, but what I can say this is the benchmark tuning Video and will help a lot of people. Proud to be a patreon of your Project since a Long Time. Great job JQ! I have heard so much scrap at the tracks about tuning and some pros who never told there methodic or told wrong infos to the people. This video brings Light in the mystery of engine tuning.

@ricardocasmota 3 года назад

Top top top!!! I love the format, fun and really technical... Good job JQ

@jocaz 3 года назад

Well done, great ... I watched everything at once 👍 If only I had this video when I was driving nitro!

best nitro tuning video ive ever seen!! thanks for this really. and this is coming from a guy who ONLY has nitros over 25 of them and this was a great help.

@jgheal 3 года назад

I don't do comments. I'm an observer but this video has driven me to write something. The RC nitro user base and industry are in decline. This is what one of the larger RC manufacturers should've produced ages ago. This sport has a very high learning curve and the more online tutorials like this the better. No contest... the best nitro engine explanation video out there. Well done JQ.

@invisiblespeedrc 3 года назад

Thank you. My current frustration level at this industry, the large brands, the federations, the professional race promoters, is through the roof. This youtube channel will address the elephant in the room. I am just working on the way to do it as well as I did this carb video, if you see what I mean.

@stevecollette6371 3 года назад

Great video keep them coming how bout gearing, clutchng,

@jackdurden466 3 года назад

Good call, I’d really love to know more about gearing changes, and possibly clutch changes.

@nitroco2151 3 года назад

I can understand this. Very clear and precise, thank you. This is an awesome channel, I like you mix some laughs in there too. 🤣

@jayriggs1115 3 года назад

I love this video im only on my first season with nitro , anybody that has shown me anything about tuning they just say this is how you do it and dont explain it at all

@albrenes22 3 года назад

Great video, I now i have the confidence to tune my own engine. I was so tired of asking guys at the track and hoping it was done right.

@darweez 3 года назад

Thank you so much for this video! Re tuned my engine with your procedure and worked great! Power was unleashed!

@daniely30 2 года назад

Hat off to you sir. You do know what you doing. I messed with carb for 1 hr based on your recommendations, and tuned it so well, i never seen this tmaxx run this good. 👍

@user-px7zb6ku3x 3 года назад

I have been doing this the hard way for so long. Thanks JQ!

@justinmallaiz4549 3 года назад

I've been casually searching 'how to tune nitro engines' information for over 20 years.. hoping to find a couple of missing insights needed to up my tunes beyond the basics... I Finally found it! Brilliant, Thanks.

@chrisharper3524 Год назад

Superb video. Just wish I had seen this before messing around and changing all settings on my carb meaning it won't run! Will use the knowledge now to get it running so thank you. Brilliantly edited too!

@christopherbourke1514 3 года назад

This was the most informative video on tuning I've seen.....along with the inner workings of the carb which helped understand the tuning tremendously. Thanks so much JQ!

@sevenreviews 3 года назад

Thank you so much. Just got a 1/16 blur and I did the break in thanks to u, I made a mistake and messed up my carb settings and was able to get it back and running thanks to you. I greatly appreciate!!!

@jimmyramkisoen191278 2 года назад

One of the best guide ever. Finally i understand de sound of my gtx18 engine. Today fine tuned my kyosho dst rc car. Thx!

@NitroMeep3.3 Год назад

I'm so new to nitro, and I bought an OS 11k R for my revo 3.3 and you are saving me. This is great stuff

@hillbillyspeedshopandgarag4564 3 года назад

I’m just getting in to nitro rc cars so I found this more than extremely helpful because much like my big cars I want it to run perfect every time

@shaun7494 3 года назад

Thanks for the video JQ. As a average joe racer i found your video extremely helpful. . I’ve never seen or heard of any video that explains everything and goes into such detail about tuning a nitro engine. It’s very very easy to understand. I can’t wait for more of your videos to come out.. Thank you

@invisiblespeedrc 3 года назад

I practice on lefty. If he gets it everyone will lol

@scottsalz6899 3 года назад

Extremely helpful. I will be running nitro next season and look forward to applying the info given in this video.

@andyfrancis5277 3 года назад

Great breakdown on every part of the process. Showing the problem, explaining why it's doing what it's doing and how to correct it. Perfect, it makes it easier to diagnose the majority of issues with nitro. Thank you.

@davidwagner7452 6 месяцев назад

Neat how every screw on that carb has an o ring on it. I've got a 20 year old Ofna with a Force 3.5 and its carb has a high speed needle and mixture control valve but no low speed needle. It's been a lot of fun to work on and learn tuning on. Thanks for the great video.

@sixspeedbri 2 года назад

I'm so happy I discovered your channel and watched this video in it's entirety! I just got an old Revo with an OS18TM and it hadn't ran in almost 10 years, and I had no clue what I was doing trying to tune it. Thank you bro! Liked, subscribed, and shared!

@benhong3528 3 года назад

Best video for nitro engine tuning, period.

@alikhawaja6362 11 месяцев назад

I just wanted to say I’ve followed this video closely and it truly works. No two stage idle the engine has never run better. Thank you so much.

@mateuszmajkowski8034 3 года назад

That's great amount of precious knowledge. Thank you thank you. I've just bought my first nitro rc and waiting for package. After tunning it will go at least 200 stechokilometers/h!

@Js_junkyard 5 месяцев назад

I have to say it again because I’ve watched this video maybe 4 times now, great job. This has helped me tune a brand new engine after a break in, it is my very first nitro car. Excellent information.

@RCWright 3 года назад

This is the best video I have ever watched regarding tuning..thanks for taking the time to do this! Looking forward to more vids 😀

@davelowets 2 года назад

This is DAMN good advanced Nitro tuning advice. 👌 It took me years of playing with Nitro R/C engines to learn how to tune like this. This video will save you all those years of learning, and pack it all into an hours worth of your time. WELL worth the watch if you want to learn to tune like a pro... Cheers for the time you invested into this excellent video! 👊 🍻

@ididfilmit7097 4 месяца назад

As I delve into the hobby, I'm keen on mastering what I consider the most crucial aspect of nitro cars: the engine. My research has led me to understand that a well-tuned engine is essential not only for a successful day at the track but also for ensuring the engine's longevity. Prior to discovering your video, I watched several others. Yours, however, stands out as the best, and I strongly recommend it to everyone, especially before they start their engine for the first time. I have ordered two nitro cars-a buggy and a truggy-and while waiting for their arrival, I was initially discouraged by the scarce information available on engine tuning. That's no longer the case. Your video has simplified the concept, making it accessible to everyone. Thank you very much.

@74Cosmo74 3 года назад

Your explainations are so clear that it actually makes me want to try nitro again, 20 years later. I really appreciate the jokes and the light tone but also the fact that when you are explaining a technical and somewhat difficult aspect, you stop with the banter. Some vids on YT are just annoying with too much editing and meme references. Please keep on making these vids!

@Kevin.L.Jackson 3 года назад

Honestly I didn't think I would learn much from this but the way he broke every little step down honestly surprised me. Definitely DEFINITELY worth a watch. I was having all kinds of issues trying to tune my nitro engine but now I know for sure I can start from scratch and get it right. Thank you for all the information and keep up the good work!👌🤘

@muchagrande1687 3 года назад

As a complete noob in nitro racing this is a god send. Thank you very much! The split open carb answers so many questions i had. The way you add all this extra contextual information about the why is very enlightening. I'm certain this video helps out the RC nitro hobby a lot. Again thanks! I will be buying your book. Suggestion for a new video: How do different pipes effect the performance of an engine.

@togisloveya8087 3 года назад

@cbrwix6999 3 года назад

Fantastic video. I wish ppl who think they are good tuners would watch this because JQ nailed it with the 2 stage Idles are not ideal and you want to achieve a single stage idle at all times. I love how he goes into great detail of tuning a Nitro Engine. 100% Dead On Balls Accurate. Thank you JQ for a fantastic video.

@carlosfranklin236 3 года назад

Awesome video JQ, very well and eloquently explained. Learned a few things even though I've been racing nitro for a while.

@Patchwork66 3 года назад

@robertmoore119 Год назад

I remember some years back when you were working on your prototype car. I was thinking about getting into 1/8th nitro. I have always been an AE guy, but I wanted the JQ car because it was new. Very cool to see that you have gone this far, Good Luck! I only watched 5 min of the video, for others reading, but there is a pro secret at 4 min 45 seconds.
