How To Put a Basic Tune On a Nitro Engine (Tuning 101) 

+steven callahan No problem! Glad the video helped you out!

+Thomas Herring Not a problem! Glad the video was helpful to you! Good luck with your tmaxx! I'm sure your son will absolutely have a blast with it!

Totally agree man, well explained for a average Joe like myself. I was ready to either sell my redcat monsoon or trash it until I just watched this video

I agree this is a nice video you should have looked harder (like he did) because these guys below were publishing plenty of tuning videos years ago. As detailed and/or as succinct as you want- go look around they have them. In fact they were probably the first to do as you said “run the car” which is the only way to do a tuning video IMO. Their channel is not that big, however but they definitely aeee the first to show out (and challenge others to as well). IMHO. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pSh8NDTBQEo.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YO6dQE0wYDA.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0YhC7Y_ySSo.html (Etc) Like I said if you Ike this look around they’ve got it all

Lol

+Jay Daws Great! Glad to hear that it was helpful to you!

+Alex Darger Good deal! Glad I was able to help! Nitro is a lot of fun once you get past the tuning learning curve! Have a good one!

+purrungas2012 Thanks!

+Lance McGrew Lol I hear ya!

+Maria Maniscalco You are very welcome! I will hopefully have more to come in the not so distant future. My home was hit by lightning and blew both of my computers so I can't upload videos unless I just do unedited ones through my phone. Glad the videos were of help to you!

+triipiix187 Good deal! Glad the video helped you out! Have a good one!

one more thing..i have an sh 18 engine but it wont suck in any fuel ..any clues ?

+triipiix187 I would check your fuel system. It's usually an air leak in either the fuel line, where they connect to the tank / carb, a hole in the line, or the fuel tank lid isn't sealing off completely. You can always prime it by taking the fuel line off where it connects to your pipe and blow in the fuel line and watch for it to enter your carb. Hope this helps. Let me know how it goes!

Average Joe Nitro thanks for the reply ! i will do it when i switch engine again

+Trav Thanks a lot!

+Michael Drum Yeah, I say that because every nitro engine I have ever owned besides this one will at least engage the clutch at factory settings. I expect a factory needle setting to be at least proper enough to begin tuning from but this thing is much different! The Novarossi engine I just got is the same as every other engine I have had..the factory needle settings will run... But run rich... This one will barely even start at their factory settings.... And yes you are correct environmental factors play a huge role in these small sensitive engines.

+Michael Drum After making this video I figured people were going to misinterpret what I meant by referencing factory settings. I am not the best at articulating things lol. Thanks for the input!

Average Joe Nitro I'm watching the novarossi video now. On the novarossi, once running 1.5hr lean on the low speed and bump the idle up. It's doable from factory, running 25% nitro 11% oil with a medium plug. I'm only responding because the idle isn't laying down instantly on this video....Just some constructive criticism man...Good video, not taking anything away from that. Better then 90% of the pro's videos....

Average Joe Nitro you did a great job, only thing id mention is this would be waaaaay after breakin period...Props to doing what you do to help people. Like I said, better then 90% of the pro's supposedly helping people getting into this hobby/sport/money pit.

Michael Drum Yeah, I have responded to others about that very thing about the idle. I usually take more time to lean out the LSN a bit more to get the idle to lay down instantly but the video was already so long that I really couldn't go into a super fine tuning deal. My werks clutch videos show a much better tuned engine. I in no way am saying that this engine is tuned to its best by any means. Just trying to show a simple way to get a good baseline tune. I appreciate the compliment! I understand what you are saying.

+Rachel catone That's great to hear! Glad I was able to help you get your nitro screaming! Have a good one and thanks for watching!

+charlie b No problem! Glad you liked it!

Glad it was helpful!

+James B (203Killa) No problem! Glad it helped you out!

My steering turns left right slightly it has no power to turn all the way. I put in 4 brand new batterys too from 99cent store.

+Maria Maniscalco Sound like you may just need to lean out the LSN more. There could be other reasons but I would start there. Turn it clockwise and keep trying the pinch test. Let me know if you are still having trouble.

Thank you

+andrew richey Awesome! I have eyeballed the Mad Force Kruiser for a while myself lol. Looks like a slick truck! Love the old body style that it comes with! Have a great day!

Also the settings might be really rich so that you can break in your engine. I have an Hpi Trophy Truggy 4.6 and the manual says the settings are set rich for breaking procedure.

Kyosho wants you to break in with a throttle restricted plate. So likely the factory settings are geared toward that.

+Homebrand Bleach Thank you very much for the kind words! I really do appreciate that! Have a good one!

hey man how many turns out s your idle screw

+Chris Hession No problem! Yes they are indeed very similar to small engine two strokes. They can be a lot of fun when everything is dialed in but can also be a real pain at times lol. That's just engines in general though. Good luck!

+Nitro RCNerds Yeah it's been a great RTR engine! Best engine I've had on a RTR hands down! It's got 9 gallons on it and it's starting to get tired now.

Nitro RCNerds I have a new engine I recently got and it's bad to the bone. It's a modified Novarossi Rex Legend 28-8. I've got it in my Losi LST XXL 2 MT.

+Stanley Mercer I love tower easy pay! Lol can't beat it! Interest free too! Thanks for watching and subbing!

+Stanley Mercer You should go check out my new Losi Monster Truck videos I have been putting up recently! I love it!

I definitely will here in a few minutes.

your welcome. gotta love easy pay. and I usually go by Stan.

+MRBRUSHLESS Thanks you very much! I enjoy watching your videos as well!

+airbats801 Thanks! Glad it helped you out!

Thanks 💯

+Jacob Ramotar Glad it helped you out! Thanks!

+Infected Gamer Thanks! You are very welcome! Keep an eye out on my channel for a new modified engine that will blow the socks off of this engine very soon! Have a good one!

I have subscribed to your channel, hope to see more soon. I want to get back to Rc racing :D

Hey joe after seeying a couple of your video's i have decided to go back to rc. Now.. i am not sure what to get. I already saved up quit alot for a nice car. But what would you do. 1/8 scale nitro/electric or 1/5 on gas? I can also start with 1/10 scale truggy's again they are a bit cheaper. But i want to start off good. With my Tamiya Mad spirit i started good.. that was till i put a bigger engine on it and ruined the car. It wasnt ment for a big block. :/

+赵桐 Thanks!

+Mr Taz Good deal! I hope you enjoy it!

+Nitro RCNerds Yeah, I'm fairly sure that it was a fat LSN because I usually tune it to where the idle stalls out on the pinch test a bit sooner but was needing to end the video because of length concerns. It takes me forever to upload long videos. Lately I will set my LSN and will continue to lean it out along with a preset carb gap of . 5mm until the two stage idle goes away. I've also tried the method where you run a WOT pass and stop the kit abruptly and let it sit for a good 5 seconds or so and then stab the throttle and look for smoke signs to whether it's lean or rich. As I've stated before I would be interested in the guide you are putting together. I plan on getting a buggy for my next RC (looking at the Tekno buggy) I am planning on going with either a Novarossi Paloma or an Alpha Engine. It would be cool to try the guide out that you have when I get the new buggy. Will more than likely be a couple of months or so before that happens though. What .21 class engine would you recommend?

i will recommend the Novarossi Virtus, Novarossi Bonito 7xlbs, then you have the Reds engine.RB's. I am shooked over how brutal the Virtus is. It's the meanest buggy engine i have tried and own and it will also kick ass in a truggy. If you want a brutal fast and strong engine from low, mid. to a Incredible top end With a 9886pipe and a 41019 or a 41001 manifold, maybe the last one 41001 would be better so you have a overall strong and fast engine. I use the 41019 manifold cause mine is modifyed and hits 60 mph in a couple of Seconds if you gear it up from Stock and 2 T more on the clutchclock.

+Nitro RCNerds Yeah, these carbs are a bit different on the LSN. They are on the opposite side of the slide than the other engines I've had. I haven't had this one broken down yet but I noticed that in the exploded view it is actually compensated with a spring on the other side of the carb. You should check out my video on the Werks clutch I just slapped on this Truggy. It's (imo at least) tuned about as good as it's going to get. Let me know when you see that video if you think better power can be achieved or not. With regards to stock settings, I expect a stock setting to run well enough to start dialing a tune in from there. I have never had a manual tell me a stock (break in) setting that will barely even run lol. Looking forward to seeing you what you have put together! See you around!

For sure, I'll check out the vid with that Werks clutch.....big fan of Werks, I have quite a few of thier products (engines, pipes, speed clutch, etc.) We'll have to agree to disagree on what a stock setting represents. I can only speak to the brand/makes I own, (Novaroissi, HPI, Werks, O.S,, Alpha, Losi, Hobao,, Orion, and REDS). I feel like I'm mssing a few, but my pernt is on 100% of those engines "stock" is what comes out of the box. It's intended to be nothing more than a safe way to start the engine and begin the tuning process. On many of them, you have to tweak a bit (lean out to keep it running) but stock is not intended to be a tuned engine (at least for those makes). In fact, most don't even have a "stock setting". Flush/flush is where you set it to retune. Thus when I 're-tune' the engine I put it back to stock. Of course, can't speak for Kyosho, unsure of what they consider, stock....BUT I would question how they can recommend a 'needle setting that guarantees anything other than the ability to start it. Okay, this is a loooooong -winded way of stating to me, stock is a myth. It doesn't exist. But for sure will check out the Werks clutch, and will no doubt put it down concerning the approach I take to tuning. Just keep an open mind and willing to do some things completely different than what you've always been told. try it out and then see whatrs up. ;-)

+Nitro RCNerds Yeah, I see what you are saying. I am basically meaning the way the manuals for the engines I have owned usually say that the engine is set at "factory break in settings" out of the box and shouldn't be touched unless having trouble keeping it running. This engine when set at those "factory settings" won't even hardly engage the clutch lol! Anyways I just thought it was rather odd that it ran that sluggish even set to a "factory break in setting" considering that every other engine I have ever owned would at least run at a very rich state where as this one is barely able to get started at those "factory" settings. Thanks for the input man! I thoroughly enjoy talking RC with you! I'm really looking forward to seeing what you put together on tuning! Have a good one!
