I like Saito engines myself. They are kind of ugly but are lighter and more powerful. Plus you can put a "Yeah it's got a Hemi" sticker on your plane!

There's probably three times as many Saito engines in service as there are OS four strokes

Sport_Pilot

My choice is not listed. Thunder Tiger. Magnum is also not listed. Really SC, ASP, Magnum should be listed as a single choice.

G'day all. I currently have some 21 four strokes. 1 x ASP, 1 x Enya, 1 x Laser, 4 x OS, 13 x Saito and 1 Thunder Tiger. I guess you could say that the Saitos are my favourites.

I have had quite a few ASP/Magnums over time but I always seem to sell them. They are fine engines but I never become really attached to them.

I have only had two Enyas. They are great engines but I sold the 53 I had as a friend was looking for one to make a pair. My old 41 I will keep as a representative sample of a great brand.

My one Laser I recently bought and I am yet to use it. I am so far very impressed with its build quality and its reputation so I have great hopes for it when it goes into a Decathlon which is on its way.

My first few four strokes were OS. I have had a few and I like them but like the ASPs, I never really become attached to them though I do like my Gemini 160.

I have only ever sold one Saito and that was a mistake. I did give a very old one away to a kid once though and he is still using it. I love my Saitos because they are easy to get along with, easy to tune, reliable and long lasting. I also like the old fashioned look. They look the way a piston aircraft engine should look for the sorts of planes that I fly. I also like Saito because Saito is a four stroke specialist. Most other companies also make other types of engine. Saito just does four strokes and does then well.

I have only had two Thunder Tiger four strokes. They were very good engines and ran well. The 54 I had was particularly powerful and my 91 is a good engine but heavy.

I had an RCV engine for a while. I bought it as an experiment cheaply on a certain auction site. It ran well but it was very heavy and noisy so I sold it to an Anglophile friend who loves his Pommy stuff.

I'll stick to Saitos I think.

you didn't list it,

LASER

I have about 23 Saitos, one OS .52, an Enya .46MKII a .53TN and an Enya .90 and one LASER .70. The only ones I've had outside these was a Conley 1.20 and an ABITAR 1.20. I still have one RCV .58CD.

summerwind

oh, well what happened to the Laser 1.80 you had here?

I have had many os and Saito four strokes. IMO there about the same. Some saitos have cam problems , and cant keep the valves adjusted . O.S. some have muffler problems , and valve springs wear out 50/50

Sum, I sold it to a gentleman who also bought the Conley and ABITAR. I just sold my TS90 so I'm down to my Saito 1.30 as my only twin.

I bet you wished you kept that Conley! Capt,n

John, in a way that's true but thinking logically it and the ABITAR just sat on the shelf in their original packages. I ran them a couple of times just to hear that distinctive howl turning an APC 14x6 at 12,200.

ASP and Sc are essentially the same engine. And why was YS and Lazer missing?

Cheers,

I have 4-strokes by Saito. OS, and Magnum. Just to prove teher will never be total agreement I think the Satos are more attractive (with the exception of the old twin rocker cover OS 120.

My Kavan K-50 sets right on my computer shelf. I run it maybe twice a year! I have thought about selling it. It sure runs sweet & has its own oil pan with air cooled fins on it just like the real Continental aircraft engine it was copied from to a smaller scale size. Below is a photo. Best regards Capt,n

I've 3 Saitos (150,125,70), 3 OS (120, 91, 52), 2 Enyas (120), 3 (91)Magnums. All run great. I chose Enya because the it was the first four stroke I owned. The motor was 15 years old and never missed a beat. I heard it growling but never connected the noise to the bearings going out! Not the motor's fault.

Saito is my four stroke of choice, started with them and never had a reason to try anything else because these work so well! one thing I like about them they make only four strokes and nothing else so they have perfected them more then the other engine makers that make other like the two strokes!

Sport_Pilot

I had the real Continental for a while, the oil tank was bladder shaped, small round neck at the top expanding to an oval bladder shape. This was to keep the oil from sloshing out. I don't know what they would have used a finned flat pan for.

Saito is the way to go...if you take care of them they'll last practically forever.

YS is a better engine yet...a little more costly, but a real performer.


Those two brands are the only ones I'd ever buy. I've owned several Saitos and a couple YS.

I like them all, but I own more Saitos than anything else, with Enya coming in a close second. Lots of OS, YS, HP and Sanye four-strokes too. They each seem to do something especially well over the others, so choosing one brand over another is tough.

I've have Saitos, OS's and several YS's. Nothing comes close to the performance and the sweet sound of a YS with a straight pipe on a warbird.

I has:

1 OS FS 26
2 OS FS 40 (Very old, but reliable engine, really work horse!)
1 OS FS 40 Surpass
3 OS FS 61
OS Gemini 160
Enya 4C-41 Diesel
1 Magnum 52 (converted to diesel engine)
1 SC FS 52
1 Kyosho FS 52 (Same as Magnum, but labeled "Kyosho")
SC FS 91
Webra T-4 .87 (about same weight as a OS Gemini 160 [X(], not a powerful engine, it has compressor powered by same piston who are driving the engine, also the crankcase are a compressor. Easy to start and reliable engine, it has timing belt)

The SC/Magnum are cheap, and nice to run, never had problem. OS engines are reliable engine, but cost too much compared with other cheap 4 stroke engines who are reliable enough.

The diesel 4 stroke engine are reliable and never dead stick, low idling and more economical, strong to drive bigger propeller.

Voted Saito, as my FA-30S is an absolute sweetie of an engine, and they have shown support for control line with C/L versions of their engines (as have Enya).

At this point I only have two four strokes, a Saito FA-30S and a pre-surpass OS FS-40 which is also a lovely engine.

My next four stroke will most likely be an Enya, either a 2nd hand 46 or a new 41 or 53.

cheers,
Colin

I guess I will reword the "like the real Continental Aircraft engine" lets say it was more like a Prototype they used in experimental at Continental Motors where I worked for 35 years in Muskegon Mich. I got a book showing a lot of production engines, but it does not show prototype engines. Cooling fins on any oil pan are to healp dissapate the heat from the oil...keeping oil temps lower. Capt,n

i remember seeing the Kvan back in the early 70's.......although correct me if i'm wrong, the engine was produced at the end of the 60's. Kavan was a product of excellence no matter what he produced.
the Kavan 50 was a marvel indeed and the oil sump was something that caught everyones eye.

i still have the mechanical tach (and use it for exact readings) that Kavan made back then for the hobbyist........
