My favorite engine has to be my Saito 45 I bought from this old guy in our club he said it was about 7 years old. I didn't think much of it because it has a straight pipe for a muffler and it leaked after run oil from the front bearing but the first time I started this engine I fell in love with it. It idles down to 1200 and reve a 11 X 7 to 10,000 it smokes like a chimney and sounds like a sewing machine at idle. I have it on a Kyosha Cub and it's the perfect match for this airplane. I have never had to make a single carb adjustment on it since I bought it all I do is fuel it flip it and fly it.

Y.S. 140...the first one...outstanding power and the instant transition from idle to peak throttle is a real heart sweeler.

Heh, yeah that's why I can't officially say it's a favorite . I have to run it a while first I guess. If it it's anything like my .61fx was, I'll totally love it....

Mr T.

Trust me, you WILL. Flying buddy of mine has one on a scratch built zlin 50, there was ST-2300 on it (powerful midrange gurgling deadsticker), then webra 120 (reliable, powerful midrange gurgler) and now 160fx (even more powerful, reliable non midrange gurgler). He bought his 160 used for almost half the price. He never owned an OS before that because of the price tag.
Shortly after he installed it he was so impressed with the engine and the way it run he told me that he was sorry for not buying this engine new right when he built that zlin. I can say that he is enjoying it because of the grin from ear to ear when he flies it.

By far, my favorite engine is the OS .40 LA. This little engine has lots of power to spare, turns over 18.000 RPMs, is very light, very quiet, never vibrates nor makes any weird noises, they last forever and if you have one of them and want to sell it, everyone will got nuts to get it.

Ok, lets cut the cr.., I enjoy my saitos .91 very much, probably the best engines I have owned. Among my engines I own or have owned are naturally saito 91, os70 4s KB65, tt46, tt42, os46fx, os15, os32sx, os25, os.10, kb40, os61fx, st45 and 61, os60fp and a few other.

My Enya engines. They are not big on power but they run and run and run and run and run. I think they are going to out live me.

In my club we occasionally refer to people running O.S. Engines as purists. It isn't a put down, but kind of a back handed compliment. I work hard at finding engines that outperform an equivalent O.S. It isn't easy! My favorite engine is a GMS .47. It never fails to start, excellent power, and takes very little adjusting to accomodate weather changes,..usually none at all. I have had it 3 years and it keeps getting better. Outperforms all the O.S. 46's. I realize the story would likely change if I had to run a pitts on it.

My other favorite engine is the MDS .68. Extremely smooth running engine.

All time favorite hands down.......Johnson 35. Close 2nd......Enya 45 TV BB.

Hey Flyer,

We refer to them as pinheads! It ain't that hard to find engines that outperform O.S. Just about everything in an equivalent price range does. And for you idiots that don't understand, let me say again IN AN EQUIVALENT PRICE RANGE THEY ARE AVERAGE PERFORMERS AT BEST!
O.S. = Overpriced S***.

Captin john: I have a freind in CO who has a Como .51. His name just happens to be John! It is deffinately impressivel!!!!

My favorite engine has to be my Saito .56. When I was younger my dad and I built a Smith Miniplane together and that was the engine we mounted. The engine is still in service today and running better that I could've ever dreamed. I'm building another Miniplane now and am planning to put it in there again. One simple flip and it fires rock steady at idle!

The best memories of flying I've ever had was with that combo!

When I was 11 years old (1941!) I saved my allowance and baby sitting money and bought a used Brown D from Polk's in New York.
It took me several months to figure out how to make it run - but when I got the coil, condenser and batteries all sorted out plus finally got some fuel (naptha and SAE 70 - 3 to 1, gas rationing, you know!) as soon as I heard that first BRRRRPPP! I was hooked for life. Finally lost it on an O.O.S. flight in a Berkeley Bucaneer a few years later. I cried for a week, until my Dad came home with a new Ohlsson 60!

Oh yeah, Free flight - like RC but without the inconvenience of a radio!

Delivered a LOT of newspapers to buy my first "real" r/c engine...a Fox .25 (no muffler) in 1977. Kids don't read instructions so mine ran like garbage. That's OK...I have a bunch of NIB ones now...we'll try again at some point.

Fox .36 R/C. Another that succumbed to the teenager 'I don't need instructions" syndrome. Wound up trading it off for something less memorable. I have more....we'll try again with this model too sometime.

Fox .40 "B" frame. YOU try and hand start one of these buggers at -20F OAT. You'll come away with about 3 functioning fingers on both hands combined. Power out the Wazzoo when it did run.

McCoy .35 Series 21 R/C. Bought NIB at a swap meet in Gaylord, Michigan in the late '70s. Ran like a dream. Many, many happy flights with that motor.

HB .40PDP. Circa 1981. Dream boat right out of the box...
Heavy as a tank, but ran flawlessly.

HB .50 (later "PDP'd" at Drapers R/C in CT) Ran real good until I crashed the bejeezus out of it.

OS .46SF (ring). Wonderful motor. Hundreds and Hundreds of flights. No trouble ever. Sold it like an idiot.

OS.61SF (ring). Equally satisfying engine. Not as powerful as I'd have liked, but dependable in the extreme.

OS 1.20 FS. A real pig. Got rid of it quick.

ST G34. Cute little motor. Spent a while figuring out that the "low speed needle set at the factory" was actually screwed down shut. Once we were past that...it was a jewel.

ST G4500. I really need to run that someday!

OS .70. I have 3 dating all the way back to the first introduction of the Surpass series. The perfect 4C IMO. One of OS's best engines, and perhaps my favorite thus far.

K&B .20/.28/.65 Sportsters. Super motors. Underated big time.

Another host of Fox .40's (TN/EZ/BB/BSH)....Love 'em to death.

ASP .61 (early version). I can't believe they were allowed to sell these things. Useless as supplied. Horrid carburetor...more leaks than an old tuna boat. Threw it in a box.

MVVS .61. Power out the *****. Idles like a watch. Fussy with the old design carb, but....I got over it.

Saito .56. Jury's still out on this one.

Plus...there's been a whole bunch of others intermingled in there.

I buy engines because I LIKE THEM. I don't care what anyone else thinks. I have bad spot for "clones" and thus stay away as best I can. It's a philosophical thing with me. I've had plenty of successes...and just as many failures, but I've enjoyed every minute of it all.

Kinda strange this hobby is... I can create a time line of my life with model engines.

Wouldn't have it any other way!

It ain't the OS .91FX!!!!

Still have my first big engine, a 1962 K&B Torpedo 29R Greenhead in a C/L Shoestring which is flown every now and then, but my all time favourite engine is a ST 61 Bluehead, a jewel of an engine which still starts on a bump and one flip and runs as strong as ever.

Woody 51

In order. Fox 45 Ring, Super Tigre G51 Ring and MVVS .45 ABC.

All very reliable. The Fox isn't a startling powerhouse, but it has never quit on me in flight (except when it runs out of fuel) and always starts within 2 or 3 flicks, even after a time "on the shelf."

The ST and MVVS are similar in performance. Both transformed models previously powered by Asian BB.46's, from "OK" into "WOW."

Must confess I´m totally hooked on OS40/45 FSR engines, they combine silky smooth running with excellent power and throttling. See attached six of them from my collection of a dozen+ or so (and boxes of spare parts).
Can you see anything strange in the photo... ???

What's the story on the LH exhaust?

Flyboy Dave

My Feedback: (21)

....someone assembled the motor "front to back"....
which can be done. I'm not sure if it would run that
way without a reversing crankshaft..... ...
and then I'm not sure it would run....

....lemme think about it.... :stupid:

Flyboy Dave : Let me go back in my gray matter , Yep it will run Ok that way . If you want to reverse it if my memory is right you need to rotate the front housing 90 degrees to the left , that will do it with out a reversed crank. I think , getting old you know! MAX H.

The story behind the LH exhaust is that I want both pipes to exit on the same side in a push-pull canard to better control the goo. This engine runs just as well LH and gave me 16.200rpm with the pipe which is within +/- 200-300rpm of what is normal in my collection. No other adjustments necessary, cardboard box "aftermuffler" will stay on the ground........Cheers/Harald

In 1959 it was the Johnson .32, just simply tremendous power compared to the McKoy .35 redhead which was the standard in my C/L crowd.
Now its the Moki/RCS 215cc gas radial. Bought it 2 1/2 years ago, the kit's still not finished, but I run the engine just for fun! I like engines!
For everyday, I have a Saito .56 that just runs great, with a perry pump.
