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 роки тому
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 роки тому
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 10 місяців тому
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 10 місяців тому
@@wolf16731Awesome. Thanks so much for coming back for an update! 👍
@broodro0ster 3 роки тому
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.
@HONK3Y Рік тому
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.

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 👍
@alexandrenevraumont1716 3 роки тому
From far the best video ever on how to tune a RC nitro engine, just brilliant !

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🏎💨💯💪💪👊👊👍👍
@mikeiz6944 3 роки тому
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.
@GRC-Racing Рік тому
This is one of the best RC videos on UKposts, period. Thanks, JQ. Amazing video, I learned a lot.
@NathanStorer-RC 3 роки тому
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!
@darrenjohnston3722 3 роки тому
Great video, the best there is out there on race engine tuning.

@ididfilmit7097 2 місяці тому
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.
@benpetz6816 3 роки тому
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.
@michaelvesely 3 роки тому
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 роки тому
Absolutely! The idle gap makes ALL the difference in getting the tune right on.
@claytonha7898 3 роки тому
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!!
@Hinsengrins 3 роки тому
Great video and thank you for the work and time you put in it! So far I have been satisfied with the set-up and performance of my engines. But now I know how to detect small inaccuracies and how to fix them! That helps a lot!

Been tuning for over 20 years, This video explains it perfect
@Teammugenseikeracing 3 роки тому
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

@Jaybo454 3 роки тому
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!

@XSspeeds 3 роки тому
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 )
