Hi and thank you for your comment, appreciated that. Have a nice day !

Hi and thank you for your question. Basically, eBay is one of the more or less reliable sources, but definitely, I would recommend RC Japan web store: www.rcjapan.net , the only problem is delivery time. Thank you and have a nice day !

Hi, definitely, you're totally right, you can rely on spark ignition, it is more predictable, for sure.

Thank you very much for your comment ! Definitely, I was very surprised finding this thing, timing mismatch and uneven fuel distribution. I decide to stop investing the money into this engine, because it will becomes half price more expensive, that stock price ( this is without my personal time investment). Let it be...

Hi, and thank you a lot for your kind comment and for your question. I'm from Ukraine. Regarding cutting the connection rod story - I should say, that before cutting the conrod I spent a tens of hours, going to heat up the stacked piston pin assembly with a heat gun, but with any result. That was the reason, why I decide to cut and to throw away a working 20 bucks part. You can imagine, that in an hours one of mine subscribers, and friend Tom (he is professional aero engines mechanics), gives to me an advice, to heat the piston pin assembly more with a help of a butane torch. I've also two of OS FS 61 engines in more or less equal condition with a stacked piston pin, as well, as a very similar story with an OS FS 40 engine. So, I decide to check, will it works with much higher temps of the butane torch. The result was great, at first, this works nice (I found, that it could be easily pulled out), at second, both three engine were repaired in an hours. All of them are still in my collection, and after its repairing they are in excellent working condition. So, that means, that your advice really works, and thank you for that. Have nice day !

Hi, and thank you a lot for your nice comments ! Definitely, I spent a tens of hours trying to extract deadly stacked piston pin, and every unsuccessful hour really makes me incredibly upset. But one time, one of my subscribers, which is really very nice guy and high skilled aviation technician, tells me "heat it more, for higher temperatures". This advice was given to me unfortunately, after my conrod cutting adventure. Should say, that I've almost own two OS FS 61 engines in addition, both were in the same terrible stacked piston pin condition, Using my friend Tom's advice to heat it more, both of them were successfully repaired and right now all 3 is in exactly "like new" condition. So, I pay, of course, a little more (especially, if take into consideration, that all parts becomes museum rare to find items), but thanks to Tom's advice, I've got an exceptional repair skills. So, it is up to you, to make a conclusion of that story. Thank you and have a nice day !

Hi, hello and thank you for your question ! So, it's easy. Left nipple ( ! important !) from the pilot's side) should be connected to the pressurizing tube, through the check valve (one side throughput valve), to the fuel tank direction. Second, from the right side (from the pilot's side), is connected to the fuel supply (fuel sucking ) tube, Yamada is strongly recommends to install fuel filters into the both lines, due to the fact, that fuel mix is pressurized inside the engine crankcase, so to filter all small particles. You can find more details in the engine's manual here: www.yspower.co.jp/en/data/pdf/fz120.pdf So, thank you and have a nice day !

@@crazyengines88 thanks for clarify I always install in line fuel filters, i have more question, on left side the nipple that goes to high speed needle, is that fuel supply?

@@user-mh9oz4jj5j Hi, as far, as I remember, right nipple is for fuel supply, if I understand your question correctly. Please, take care to install "check valve" in direction to the fuel tank. This is crucial.

@@crazyengines88 check valve goes to left nipple as mentioned direction to fuel tank can you confirm??

@@user-mh9oz4jj5j Hi, I can't confirm anything remotely, please, try to accept this. Better, if you will look personally to the engine's manual, where you can find an exact drawing you can find it and download it here: www.yspower.co.jp/en/data/pdf/fz120.pdf . Thank you for your question and have a nice day !

Hi, and thank you a lot for your comment ! Sure, you're totally right there. But can you imagine, how much different size tools for bearings installation I should have with all that amount of engines in my tests and repairs ? I think, at least, 10 or even more. Also, should say, that all my engines runs very nice, without any hesitations to the bearings performance. Anyhow, you're totally right and thank you a lot for your comments. Have a nice day !

Hi, and thank you a lot for your comment ! Usually, after all test runs I make partial cleaning of the engine inside, in the style, like this: ua-cam.com/video/D7irK5xAZ_Q/v-deo.html, so, my own recipe after run oil works great, protects engine inside well. Was checked engine in the storage over two years - looks pretty like new inside. Regarding the fuel choice - I'm an old-school style man in this, I like the smell of a freshly mixed glow fuel. and I still convinced with a lot of my experiments, that engines runs clearer, cooler and better (less carbon build, more dynamics) on the glow fuel instead of gasoline. This is, of course, is the matter of taste. Definitely, I like your comment, thanks a lot and have a nice day !

@@crazyengines88 Yes, Nitro makes the engine less sensitive to mixture adjustment, it's true. The down side is, Methanol and Nitro aren't just very expensive compared to Petrol, the engine consumes approx 2/3rds more fuel for the same running time. Petrol allows for a smaller tank size in the model and easily obtainable fuel. It's also a lot cleaner running, even on a very generous 15 : 1 mixture ratio (around 7% oil)....No bottom end clean ups or bearing rot either...😳😏😏

@@EnglishTurbines Thank you very much for your soon reply ! Yes, of course, gasoline is more cost and energy wise much more effective fuel, no doubt. This is from practical p.o.v. Being more practical, contemporary technologies left well behind even so effective gasoline engines, too. Contemporary Li Ion batteries with brushless electric engines shows amazing effectiveness and performance, I also working with this in another project, but I'm still standing with my old glow style engines. It's much more emotional, than rational, but museums also need somebody to work in. 😃

@@crazyengines88 Lol, yes, I get it entirely. The smell of a four stroker belching out blue smoke and Nitro fumes...Since retiring, I've spent 9 years flying electric because my interest in FPV doesn't allow for noisy vibrating gas engines...That said, I share your sentiments and have recently purchased an OS26 FS No3....a delightful little four stroke..What set me off is converting an OS forty Surpass four stroke for a friend to run on Petrol. Runs like a dream, despite being a bit short on compression...on the original carb too with minor adjustments to the Needle valve assembly...😮😏😀

@@EnglishTurbines That's great, really. B.t.w., I'm also not a novice with FPW, currently working on 10" power body. Using so powerful motors from ReadytoSky (3115), so I still very afraid of ESC overloads (~ 70 Amperes per channel), every test it runs hot, so need to tune it very precisely in a Betaflights PID's adjustments. Anyhow, this is another story, probably, I'll find the time to make a few stories about this part of my projects. Was very nice to talk with you about this small and very beautiful 4 strokers. Thanks a lot, and have a nice day !

Thank you for your question ! At 7:24 in this video there was a banner with figures, to the standard gasoline mix (20:1), I was add 10% of Nitromethane, this percentage is calculated from the fuel mix volume. Thank you for your question, and have a nice day !

@crazyengines88 I understand that you added 10% nitro.....but how much of it did you add to the gas fuel?? One gallon of gas....did you add 10% of 10% nitro to the gallon of gas??

@@michaelhunt8414 OK, I understand, what you want to know. So, usually, for 1 test run I prepare 0.0792516 US gallon of fuel mix (300ml), so I add 10% Nitromethane from that volume, it means 0.00792516 US gallon (30 ml Nitromethane). Should note, that during my Nitromethane / Gas fuel mix evaluations I found, that maximum amount of Nitromethane, which could increase engine performance, is approx. 30%. Future increase doesn't make any improvement. Thank you for your questions, have a nice day.

Thank you for your comments, much appreciated !

Hi and thanks a lot for your kindest comment ! Definitely, it's very nice to get so high evaluation from you. Thank you and have a nice day !

Hi and thank you very much for your so kind words ! Have a nice day !

Hi and thank you very much for your comment ! I think, that I'm also a person, like you identified yourself. 😊Definitely, absolutely agree with you about FG60R3 engine flaws. This flaws were stopped me to continue with it, because I don't think, that is possible to fly with engine with such behavior. Unfortunately, I've no time to search deeply for circlips tools, for mounting and dismounting it's from the engine. Usually, I use small thin flat tip screwdriver to work with, of course, it's takes an attention and consumes a lot of time, especially if circlip suddenly jumped up from engine to the floor of your workshop. 😃 Thank you very much for your comment, I like it very much, Have a nice day !

Hi, thank you a lot for your comment ! I'm apologizing for so big delay with my answer. Wishing you a very nice and great day !

In small scale than you Im working on my engines, you are a truly influencer. Thanks

@@danyrealpe289 Thank you, very much pleased by your evaluation. Have a nice day !

Hi and thank you for your comment! Definitely, I'm not sure about the overall test conditions, there were a lot of other thing happens this time. Thank you very much for your feedback, I'll improve this moment during next test runs. Have a nice day !

Hi and thank you for your comments ! This prop was OK for whole series of 50 & 60th 4 stroke engines testing, so, for flying in different style of course, you'll choose the best suited prop. For comparison test was necessary to create equal. as possible testing environment, and prop size should be the same for all engines - test contenders. Thank you for your comment and have a nice day!

Hi and thank you very much for your comment ! Definitely, absolutely agreed with your especially with the additional (over a half price of a new engine !!!) price you have to pay to fix the simple engineering mistake. This is BS#, for sure. Due to the heavy workload this time, I can't find, unfortunately, enough time for FG60R3 engine, right now more thoughts about single cylinder Supercharging in automotive style. Thanks again for your feedback, please, keep the heads up. With best and kind regards...

Thank you very much for your kind comment, I'm really appreciated for that. Thank you and have a nice day !

Thank you very much for your evaluation ! Have a nice day !

Hi and thank you for your question. Definitely, not, there was no need to change O-rings. Thank you and have a nice day !

Thank you for your nice comment ! Still has this one, I like it very much, it was very well adjusted, heads were aligned and perfectly lapped to the “zero” condition. Still is one of the best tape machines I’ve ever heard, using it as a “master tape” engine. Unfortunate y, nowadays I’m too much overloaded by my current job tasks, so practically haven’t no time to make videos about my engines, as well, as with my taperecorders , like Pioneer 707, Tanderberg and Nakamichi. Hoping, this time will arrive soon. Thank you and have a nice day !

Thank you very much for your comment ! Definitely, it is a great choice, for sure. Thank you and have a nice day !

Hi, and thank you for your very interesting question ! Definitely, I can't catch up what the problem is, may be, you have some short videos of your engine run ? There could be a real bunch of potential issues. Only one is clear enough - probably, the reason of such behavior is in carburetor settings (if you're not don't dismantled your engine earlier). So, will wait for your videos. Thank you and have a nice day !

Hi, and thank you for your question. I make this run with MAS 18x6 prop.

Hi, what's a pity, Sir. Probably, it could be repaired ? And what kind of problem appeared ? Something with cylinder surface ?

@@crazyengines88 Design error in most of these engines (maldistribution of ignition) Now 450 Euros

@@antoniomoura9347 Understand. Definitely, I've no plans to install this on any plane, don't want to invest more money, it becomes amazingly overpriced.

@@crazyengines88 Repair cost as equivalent of 1/3 of the cost of the engine

Hi, it's a very pity news, sorry. What exactly was broken ? Cylinder surface ? Or valve seats ?

@@aSpyIntheHaus Thanks a lot ! This week should be something :-)

Hi, thanks for the nice comment ! 😀 You can't believe, but I know personally at least, two people, who was using bench power supplies to power their SW receivers / FM radios. The only difference was that both have old fashioned style power supplies, with iron core transformers, so, less noisy devices. Thank you and have a nice day !

Thank you, what a great question ! Basically, in your question there is a part of an answer - the ground terminal internally connected to the metal case and chassis. If you will connect the ground terminal of your power supply (or any other electrical equipment), this will save a life. in case of a short circuit of the power wires to the device case. Short current in such cases will be directed to the ground. Thank you for your question again, and have a nice day !

Hi, that's not a problem at all. Practically, I don't too close connection to much people, who are collecting engines, so it could be an empty attempt. So, please, don't so rely on them. I even don't know, if they could have such an engine. Thank you and have a nice day !

@@crazyengines88 Regardless I do appreciate you taking the time to answering.. best regards from Daytona Beach.....

@@markgerard363 Thank you for your comment, much appreciated. Have a nice day !

Hi, and thank you for your question. I should say, that 7 cylinder Techopower engine should be a kind of miracle, it's so rare engine in novel times. Regarding fuel pressurization - this one I tested, don't show any signs of lack of fuel. It could happens in flight, especially, if you plan to make some acrobatics. But for such flight style, probably, you'll need more powerful and more "angry" engine, and for sure, on gas. I also agreed with you about your worry regarding pressurization, so for flights it will be better to add fuel pump, which will be powered from independent battery, with remote control from your radio. Thank you nd have a nice day !

@@crazyengines88 , thanks for the advice, the objective is just "fly" the engine , it is now almost ready on a phoenix Waco , will look for a fuel pump, just in case. ha ve a nice day

@@MarceloBernacchi Thank you very much for your reply, adding fuel pump to your setup should work well. Wish you a great flights ! Have a nice day, cheers.

Hi, I'm still in live 🙂and very nice to read your comment ! I'm currently working on the big project, being very busy through whole week, sometimes, in a weekend, so practically, I haven't any spare time. But I also have to inform you, that there a few really "crazy" ideas are flying around my head, so definitely, in a short time I'll be again online. Thank you and have a nice day !

@@crazyengines88 Okay. Stay well. 🙂

Thank you !😃

Hi, and thank you for your question ! Basically, if you are just making some engine tests on the bench and your fuel tank is placed with on a bit higher level, it will work fine, especially, if you need to provide quick test (working or not, or to listen bearings work). In all other cases, and you're totally right, it is necessary to connect exhaust nipple to the fuel tank. In my setup you can check this connection at 8:10 on my video, during refueling. it's clearly visible. Thank you for your question and have a nice day !

@@mikesullivan5851 Hi, nice question, thank you ! To be honest, I've no plans to make video about OS FR 5-300 in the nearest month, I've some plans to continue engines comparison 0.70 - 0.80 class, and also, have an idea about engine supercharging , crazy, of course. Nearest time about OS FR 5-300 could be approx in May, not earlier, sorry. I could mention only one engine problem - uneven fuel mix distribution, which is leads to cylinders accidental quitting ( due to over rich fuel mix). It could becomes negligible after a certain period of engine working time, but I can't confirm it, due to the fact, that my engine is too "young", two or three hours only. Than you and have a nice day !

Hi, and thank you for your question. O.S. type F is OK with its length, but O.S. G5 type has a longer tip, so to avoid direct contact with piston surface, second copper washer was installed. Thank you and have a nice day !

Hi, and thank you for your comment ! Basically, I'm owning two O.S. FS 60 engines, one is completely N.I.B, another (which was on video), has a few hours on it after refurbishment. I think, that your engine will need some refurbishment, too - I mean, that the most engines with some hours on it could have less compression, due to the old castor oil residue in the piston ring groove, it is the first reason of a low compression. Another reason could be some soot at the valves saddles. If you more or less familiar with dismantling of a such engines, it could be fixed / cleaned / adjusted and assembled back in a few hours and you couldn't recognize your engine. Thank you and have a nice day.

Thank you very much for your kind comment, appreciated ! Have a nice day !

Thank you for your comment ! This is real, there is few necessary steps you should bypass to get this or similar idle - brake in engine fully (at leas, 3-4 hours of operation at different speeds, I do not like to push an engine to the limits, so ~ 5K high speed RPM's will be enough, than, use pure and high quality fuel ( 15-20% of a high quality fully synth oil will give you an advantage is 100-150 RPM's lower). Additionally, from 10 (at least) till 15-20% of nitromethane in fuel mix also will keep you idle steadily low. Of course, glow plug model also important. I prefer OS G5, but OS type "F" will also runs great. I think, that Hangar 9 should work nicely. Thank you, and have a nice day !

great tips! I like using the G5 plugs, they are made from petrol so should work with alcohol based fuels with no issues. LOVE THE LOW IDLE, I like 4 strokes for this reason. I have the IL300 and want that engine to tick like this! @@crazyengines88
