Whoa.. I had no Idea Nova Rossi was a family "mom&pop" business :o Gotta love that personal touch, with commitment like that, you know it`s a work of passion, and *that* is a value very few can claim to have..
I do hard break ins myself.. just let it warm up the first time richen the F out of it and ram that throttle wide open for a couple of seconds. The engines love it and have been running great so far! Its just my way of doing it. If you buy a good engine like Novarossi's or something else it shouldnt harm the engine. Get it up to temp and smoothen that sleeve/piston out! With slow break-ins i always found myself not getting the best out of the engine to be honest.. Nice video of a screaming Nova :D
Sure, but with high performance engines sometimes luck also involved. Like for example my O.S. R21GT's conrod snapped near the piston pin, near the end of break in period. Everything looks fine and shiny, no scratch, hotspot and all. It was heart breaking coz I have to do it all over again. Nevermind the repair but time and fuel and tires and lap after lap went into breaking in that engine. But this guy did it in 10min....
A "couple of seconds"?? That's nothing.. I break in ALL my engines at full throttle, (rich A.F.) for several TANKS of fuel. Pinned WIDE open.... You WILL have to provide HEAT from a head heater wrap AND a heat gun in order to do it this way tho.... AND keep the temps up to around 260ish for the entire process. And you'll want to richen it enough so that the wheels of the vehicle are barely turning when it's at W.O.T. to keep the RPM's in check. BEST break in method I have EVER used, and produces nothing but the most reliable, powerful, and longest lasting engines. Break it in like this, for how ever many tanks of fuel that it takes until the "pinch" is gone, then throw it down, drive it and tune it.
@@golferchin76Then you probably broke it in with the engine too cold... The "pinch" of a new, cold engine is HELL on a rod. WARM the engine up with a heat gun to 200+° BEFORE the first start, and KEEP the temps up to at least 220 or better thru the entire break in process. If the rod breaks THEN, then the engine was a P.O.S. to begin with.. 🤷🏻
This shows that novarossi has insanely good motors. I’m running the original novarossi p5 in my buggy that came out over 17 years ago. That’s older than me! And that thing still sings. That motor is the same one on the box for the mugen mbx5 buggy which was released in 2003. I would love to get another novarossi whenever that p5 decides to give up on me
@@paulspomer16 yep it’s sad. I’ve got some flashpoint fp02s in my buggy and truggy now and those are for sure my favorite engines but my next choice would be reds since they’re basically a combination of Novarossi, Picco, and Sirio which are some of the top Italian engine brands. I’d love to see reds make a .12 though. I’d for sure get that instead of the OS .12s
Awsome Awsome video have been using their engines for years.Love their products their motors perform great in a racing environment.Have their engines on my buggies and a couple of druggies.As long as you do the breaking in properly those engines will last.Thanks for sharing such a cool video.
I have tune under load, WOT, regulating rpm via HSN....but never like this! I probably watched this video 10 times! I can't get enough of Novarossi. Thank you for the amazing content! If you can do a "Novarossi/RB Heritage Series", that would be super helpful and greatly appreciated😎🤜🤛
Interesting video, WOT controlling rpm with an external high speed needle, i guess its just easier to get to that way. The temps are insane @ 165C stable at 39K RPM. Nice video, I wish there was a follow up video or an explanation as to what his own experience was instead of letting the viewers figure that out. Good video Nonetheless
That's how it has been done with airplane engines since .. ever? The ones from the days before RC didn't even have a throttle. Real hot racing engines still don't have one.
So much for the guys saying 'I never care about a temp gauge while breaking in or ever!'. As long as the temp stays constant at a particular RPM the motor will be fine.
Can someone please tell me why my nitro motor revs full throttle but at the same time my carb is at the idol spot but it reveing like it's a full throttle please someone help
Between Nova’s method and EBIS, I wonder what works “best” for a balance of performance and longevity. Right now, I run an EBIS’d OS B2102 and given the performance and reliability I’ve seen so far, I don’t think I’d ever revert to an old-school engine break-in procedure (driving the car on the ground with engine super rich).
That old school method is really old, the conrod can break even during the break in period. Modern methods are more towards hard break-in. Some will even after just a tank of idling on the starter, go 90% race tune at the track and limit the throttle opening with EPA, but never cold start and never run it while it is less than 90 deg.C The idea is that once the engine reaches 100C and above, the sleeve actually opens up and load is tolerable on conrod-the weakest link which can break apart even if it looks fine.
Great video, didn't know it can hold such high RPM for such a long time. How often do you change out the connecting rod? Had my rod snapped just when the car/engine was running great, good temp and all.
My O.S. R21GT's connecting rod snapped around the piston pin, near the end of break-in. It felt heart breaking. And it did not run anywhere near 140deg celcius...
Man I would have been interested to hear your feedback from what was being said after the video. It was sorta hard to follow. I run a novarossi in my xray buggy and it was oil bathed broken in. Seems to run really well. But this is definitely a cut from the norm of breaking in engines.
Please we need the rest of the interview. We where getting some where, the translator was adding his own thoughts and wasn't 100% true to what Rossi was telling. In short (for this part of the interview) 165c at 38k rpm, 2~3liters of nitro of use, the temp should be at around 130~140c and 39~40ish thousand rpm. If your temps or rpm are varying then your setting wrong your carb. Ideally in an ideal situation it should be as constant as possible, both rpm and temp, even after the break in is done. Also each engine is different so you could have a different temp/rpm, not all will run the same. But if the engine is getting up to 185c there is something wrong and they wouldn't continue. Sorry my english isn't very good 😅 but at least more accurate than the translator... In the last part they were talking about how the modify the carb... But they cut it just there 😢 Hopefully we get the last part of it some day.
The last nitro powered trucks I had I just ran them, no break in. They screamed like banshees. I fly GS gas planes and we never break in the motors. Just take a little easy from hovering too long on the deck and after about 12 flights I call it good.
Really interesting as a fairly experienced nitro car enthusiast. Is it not the case that a plane would have a better quality engine and running at high rpms under lower loads makes sense. A car typically has a lower quality motor and probably owned by somebody with far less experience. A car requires more use of lower rpms and so a different break in works.
Big part of this is the basically insufficent cooling on RC cars. They have a prop on the as a load, but it also makes for a really good airflow around the head.
I also have some RC boats I have had for a month but haven't even ran them just getting back up and going from a emergency surgery I had 6 weeks ago but I hope to get out and run those soon
lmao I jumped to 4:24 n seen what I THOUGHT was gold wheels N was like GOOOOOD DDAAMMMNN THATS A HUGE CAR!! Till I calmed down n really to a close look, im a dumbass lol
I break in my O.S. R21GT on the track, hard break in. It takes me weeks to break in an R21GT (weekend visits). Time, tires, fuel, lap after lap, running up and down checking temp and adding fuel, you know the drill. Very rarely but the conrod can also break apart during this period. This guy does it in 10min ....... maybe I should make a bench like this to test on a cheap made in China engine, see if I can break it in without breaking it in 10 min.
Thanks for the upload,really really intresting video!!! Im italian and i can say that the translation from italian to english is actually not really accurate. I would be really gratefull to you if will be possible to have the entire explanation after break in process for hunderstand completly what the technician explain because was soo intresting but the video stop at half of it. Thanks in advance i really hope to can have the possibility to the continue of the explanation!!!
Ummmm professor??… 165c is 329f temp. The manual says not exceed 230f. In Italian, he’s saying once they try to break in using my method, they will be back to purchase another engine so it’s a win win situation.😂 (j/k)
Great video and a real eye opener on running in a nitro engine, its insane but please stop blaming an old camera for your constant fidgeting with the camera and being ignorant with what you are actually doing. No ones perfect just admit that your not!
As long as the nitro engine is broke in properly and tuned properly they will run very well and be very reliable as long as you keep the temps in check they are amazing.
I think it's important to remember that we may need to tier up and spend a little more for our nitro engines to be truly reliable, easily adjustable and last for the long haul. IMO, nitro is a great example of the old adage: we get what we pay for.
My Nitros can run all Day and there not even stock there Modified! I don’t go by temperature I go by how they sound to me and how they look. Like just a little smoke 💨 not a lot and not nothing at all ! I only care about temps for heat cycles in my break in process . ruclips.net/video/2JrPssK-sv8/видео.html as you can see I beat on my Modified Novarossi 28-8 with NOVAROSSI 41032 header and NOVAROSSI 9886 Pipe 💥💥💨
So here we have the truth from an expert who does it every day for a few of the best nitro engines on the market. And the whole wanna-knows in the Internet tells the opposite... Some sort of a myth declassification.
Do the post interview with the exhaust fans off or go to another room. This is what "white" noise does. Cancels out noise. Nice video, shitty post interview.
Those are experts, which have been making superb engines for decades. I would expect they know what they are doing. Also they warmed it up first, which doesn't take long at all with those small engines. I tried it recently with one of my (plane) engines on the test stand, maybe 20-30s. The common reasoning behind it doing this way is: After you have reached a certain manufacturing precision, break-in doesn't have to "rub off" manufacturing impurities anymore. It then just have to make a fine seal, and you want this to happen at the specified load, because engine parts deform slightly under temperature and pressure. If you break it in under lower load, the seal will be perfect at this load, not at full power. Lycoming as a manufacturer of full-scale airplane engine even prescribes doing it that way for a new engine or after an overhaul: www.lycoming.com/content/hard-facts-about-engine-break Yes this is for ringed engines, but it is even more important for ABC engines (and every single car engine is an ABC engine nowadays). Those are manufactured to fit at operating temperature and pressure, which is why they are tight when cold and new. You actually don't want to wear the tightness away, since this material will be missing later when it gets hot. There is one exception in RC engines, and this is a lapped iron piston engine. Those pistons (due to their metallurgy) expand slightly during the first few hours of running, therefore you have to break them in slowly and let them totally cool off between runs.
@@JarosRC Do it right and it's not a lot of work at all. Too many people try with crappy RTR engines that never run right. Fuel it up, put in your base startup tune, lean out when warm. Run. When done, pray in afterrun oil while it is on a starter. Done.
If i broke in a nitro like this, the cops would be everywhere. Is this a better break in? Or should i stick to average joe shmos technique? If a company that builds them does this, id say its ok.
It's a better break in because the engine is loaded and actually near it's operating tempature but slightly rich, when the engine is warm running it promotes a tighter clearance between the piston and sleeve = less wear Idling makes the engine run cool which makes the clearances increase= more slop between the piston and sleeve causing more wear.
Well that’s just a dumb statement. I haven’t completely converted to electric. I still run nitro on my own. There’s no new nitros on the channel because manufacturers aren’t making them. You do realize I don’t make this stuff right? 🤦♂️
i rember breakin in ny new o/s 90 marine engine 20 years ago i had to shut it down the noise made wax run out of my ears i think it was 25x louder than this my dad came running out of the hose to tell me shut it down befour the neighbors called the cops i had it at 25% whith a tuned pipe in a miss budwiser wooden kit it was perfect i also built a payday and atlas van lines cost over 600 ea to build but were they beautifull tower hobbies loved me
@@paulspomer16 Well if you ask it that way. Money was the reason. but they lost all their factory drivers to either OS or Picco at that time. Plus the under performing Vitus line of engines did not help. In a nut shell... the competion just caught up to Nova Rossi and the pandemic.

If i broke in a nitro like this, the cops would be everywhere. Is this a better break in? Or should i stick to average joe shmos technique? If a company that builds them does this, id say its ok.
It's a better break in because the engine is loaded and actually near it's operating tempature but slightly rich, when the engine is warm running it promotes a tighter clearance between the piston and sleeve = less wear Idling makes the engine run cool which makes the clearances increase= more slop between the piston and sleeve causing more wear.
Sadly, they're out of business because someone like you completely converted to electric? 😄
Well that’s just a dumb statement. I haven’t completely converted to electric. I still run nitro on my own. There’s no new nitros on the channel because manufacturers aren’t making them. You do realize I don’t make this stuff right? 🤦♂️
Can't really see that engine and shit its loud
i rember breakin in ny new o/s 90 marine engine 20 years ago i had to shut it down the noise made wax run out of my ears i think it was 25x louder than this my dad came running out of the hose to tell me shut it down befour the neighbors called the cops i had it at 25% whith a tuned pipe in a miss budwiser wooden kit it was perfect i also built a payday and atlas van lines cost over 600 ea to build but were they beautifull tower hobbies loved me
I would never break in my engines at full throttle not the way Todo it
Why did they go bankrupt?
Because OS's make better run time with almost the same power. But nothing beats a Novarossi for durability. This is for the onroad 1/8 scene.
@@lilbump406 You’re meaning to tell me the reason Nova went bust is because of OS? Yea no that is not the reason.
@@paulspomer16 Well if you ask it that way. Money was the reason. but they lost all their factory drivers to either OS or Picco at that time. Plus the under performing Vitus line of engines did not help. In a nut shell... the competion just caught up to Nova Rossi and the pandemic.
@@lilbump406 That’s only off-road though. They absolutely dominated the on-road scene from what I have heard.
@@paulspomer16 I'm only referencing 1/8 nitro onroad. I can not speak for offroad.
I don't think this is a breaking in process...its more like pushing the engine to it max limit and analysing the breaking point 🤔
Always let your car idle for s full tank idleing and work up never flat out like this
