When I had my Saito 1.50 I found it easiest to hand start by priming then flipping it backwards. It bounces off that compression and fires the right direction. Mine was fabulous. Was in my great planes super skybolt.
Brings back memories of flying "Old Timers" in the 80's with Saito 4 stroke engines. Back then, we found that running on castor based fuels over a period of time, the main bearings broke down due to condensate forming in the crank case and causing rusting. The solution back then was to run on synthetic based oil in the fuel and limit the ratio of nitro. Another trick we did was to remove the glow plug at the end of the days flying and drop a few drops of mineral based oil in the plug hole and turn the engine over a few times to lube the main bearings. This virtually eliminated the problem, though not entirely. Probably engine technology has moved on since then or was it just our damp weather that caused the problem in the UK? Look forward to seeing what model you install your motor into..
I have never experienced that sort of issue with any glow engines in the US climates I have lived in. It is customary or at least recommended to end each flying session by running all of the fuel out of the engine. The remaining oil left is protection enough between flying sessions. Longer term storage requires some after run oil of course. You will never see me install this engine in an airplane however. More familiarity with my channel will explain that.
Great running engine, David. Love that dependable idle, so important to those landing any gorgeous plane this engine is intended to power. I've taken specific note of how carefully you brought this engine up (momentarily) to full power and your caution with the mixture. I believe these engines need at least ½ to 3/4 gallon of fuel run through them before full break-in is realized. I'll be needing to do the same thing with the NIB Thunder Tiger 91FS I have. (or perhaps you would like that honor!) I intend to put the TT 91 on a Great Planes Revolver, even though the plane would be very happy with an engine like the Saito 150 in this video. So, I am officially jealous.
thank you David as always for such an informative fun video. I've got (3) FA-150s and they are super reliable fantastic engines! greetings from colorado. ;)
This is a gorgeous engine indeed - must be an older one, judging by the muffler. Used to absolutely adore Saitos, until - you may remember - in early June my otherwise wonderful FA-220 blew up in the air and torn its internals to pieces with just 34 hours total running time. Cost me a rather hefty 3-figure sum for the necessitated parts and I've yet to rebuild it. I still like them though in general, though I clearly prefer Laser engines now. Indeed anyone disliking videos like this one must be distasteful. Great running thing, keep them coming David. Regards Harry
Harry, it sounds to me like you are blaming Saito for your engines demise and I believe that is an unfair assessment. ANY engine from ANY manufacture can have something like that happen.
@@dmrcflyr2David, I am not blaming Saito themselves for the untimely "demise" of my 220, however it is quite unusual for such a low - hour engine to blow up. I haven't heard anything like that for Lasers (and I've turned the Internet upside down in research, believe me) and most OS engines to be frank; I realise such a possibility can exist for all engines; I've had a wrist pin come loose in my first Irvine 72 in 2006, seized in mid-air and it had to be sent back to (then) Irvine to be fixed with just 6 hours running time. It's just that one absolutely doesn't expect such a thing to happen, and it is accompanied by massive frustration and inconvenience.
Completely understand. I have never seen any glow engine manufacturer publish or state a life expectancy of their engines in hours, minutes, or seconds. There are simply too many variables, most of which are related to the operator or conditions of operation.
Despite your research i would question that many modelers ever put that many hours on a single engine. Heck most people don’t even record the number of hours they log on a single engine.
@@dmrcflyr2 Hi David, replying to both your answers :) Living in Greece ensures my engines never get too cold or hot, plus I never squeeze "every last rpm" out of them while ensuring more than adequate cooling :) As for logging the running hours; that "descended" onto me from my late Dad, who used to be a full-size pilot with a proper logbook. I log the number of flights and flying time per session, every time - I do find it quite useful in assessing engine maintenance needs and knowing total flying time per year - it's sort of a personal thing ;)
I like the video a lot as i do for all your efforts. But i have a teoretical problem i have been thinking on a lot. If you run an engine and then inverted it. Will carb settings and everything else be the same? To achive the same performance? I have not done it by myself, because my engine stand doesn`t allowed it. Greetings from Sweden
No the carb settings will not be the same. I learned many years ago that the look of an airplane is less important than the proper and troublefree operation of the engine, so I stopped running them inverted.
Boa noite senhor David, gostaria de saber se o glow plug OS F é quente, média ou fria, obrigado pelos esclarecimentos, Sidney William, de São Paulo- Brasil.
@@FMo01 muito obrigado, me falaram que este glow plug tem um bom rendimento em motores glow 2 tempos de grande cilindrada 26cc e acima o Sr. concorda com isso.
@@williamworkscamperdizforin2241 Nos motores de grande cilindrada, as velocidades do motor são mais baixas do que nos motores de pequena cilindrada com intervalos mais longos entre ignições, como nos motores a 4 tempos. Por conseguinte, é possível que a vela de incandescência OS F funcione bem em tais motores.
@@FMo01 Vou por em prática o uso da vela F tenho vários motores para o amaciamento dentre eles modelos da Super Tigre de 23cc/25cc e 45cc e motores OS Max de 17,7cc/26cc e 35cc. Relatarei os resultados.
Sei froh, in den USA zu wohnen. In Deutschland kann man Nitro Sprit nur noch ganz schwer kaufen. Außerdem haben sie zusätzliche Steuern auferlegt. Ein Liter FAI Sprit kostet zwischen 5 und 7 Euro. Das sind etwa 6 bis 8 $ .
Here in California we pay a hazard delivery fee over $ 50.00 so 4 gallons may be $100.00 then hazard fee and tax on top of that. Total over $ 165.00 but Saito's are very fuel efficient.

David I love all your videos and all who dnt can kick rocks another great video I have a question I have a saito 180 I’m using 10% omega should I add any extra oil to it I think I heard you say you add something to yours thanx an keep up the great videos
I don’t recall stating that I add anything to my fuels. I simply mix my own FAI and I use castor. I will then mix my FAI with off the shelf nitro fuel of 10-15% to make 5% fuel. Omega 10% is good to use. I just don’t use anything over 10% as it is not necessary. These engines will run just fine on 0% nitro fuel as I have shown time and time again in my FAI Experiment playlist.
Love the stuff dave I'm 52 yrs and been in the hobby since I was 14 yrs. Long live GLOW!
Kids these days will never know the magic and sweet smell of glow engines ❤️
Possibly, but i would like to think that my videos might inspire others to experiment with glow engines and love them as we do.
Never owned a bad Saito yet. All have been easy starting and easy to adjust.
great runner. looks like a keeper. motor sounded great.
That was awesome Dave . . . now I gotta run my Saito FA-220 Zeus for the first time . . Thanks for another outstanding video :)

Thanks David, I needed that!
Awesome run, thanks for sharing.
Great engine!
love it
David, Great engine, great running. We enjoy what you do.
Thank you Calvin!

Well I am not attached to this engine Floyd.
Well, what can I say? It's a Saito, a thing of beauty. I can't fault O.S, but I love the looks of a Saito.

As you say, its a beautiful engine .perfect run for a new engine .

aww hell they probably just MAD they cant smell the burnin nitro !

That's a Huge Fricken Engine! It's Brand Spanky New!!! It's a Saito. It's a High Standard of Stanardness!
Sweet sound specially at iddle, just like it should from Saito, the B series are not the same in my opinion, at least the 150 B series.
