Default Saito .30 vs. OS. 30 4-stroke

Does anyone have any personal feelings on the Saito .30 vs. the OS .30 4-strokes? The Saito appears to be .9 ounces lighter with the muffler, but I haven't found much else to compare these two engines.

Both very good engines the satio may have a little more power . I had a 26OS ran well but not a lot of punch when they went to 30
they got more out of it I would buy the one that was a better deal to close to call

I have a OS 26 that starts and runs nicely. It's also easy to set the needle. I have it on a small 3 channel plane. It is a long way from having as much power as a 2 stroke OS25FX.

Hobbsy has a Saito 30 that he speaks very highly of.

Enjoy,

Jim

Someone that I fly with has the OS and loves it. I've got two of them. Eventually they will be going in a twin. Started the first one yesterday, and only one tank of fuel so far. If the ground testing is any indication of how it will do, it's a great engine. It's in a small Cub ARF I got off of ****. Hope to put it in the air today (guess I'll have to change my sig). If I do, I'll try to post a report.

my FS 26 was never a problem it was traded in when I got the Saito 40 which is now in the waco 30 (have not flown it yet) it would not have been enough power they said perfect for the magnum 4 strk 30 but I believe it would be underpowered with any 30 4 stk the saito
40 was not that larger and needed a little wt in front besides

I've seen several of the OS .26's run and they are sweet little engines. The project I have in mind needs to have a light engine which has me leaning towards the Saito. I've run both OS and Saito in the past but have no hands experience with either of these .30's. I guess I'll just have to go down and pick one up so I can find out for myself how they are!

I had (sold when I moved) the OS30 on a .26 WM Cub, which incidentally is my avatar. I never had any problems with it. I loved this plane. It didn't fly aerobatic but it flew better than scale with short take offs and slow landings. This is the engine that sold me on fourstrokes.

Hello; I have a few Surpass 26's and like them quite a bit, I had one in a Speedy Bee, and have one in a slo poke, I have a Saito 30 in a Pixie bipe, The Saito has a little more poke, and throttles a little better (prompter). I have seen a Surpass 26 used for 8 years without any attention, then the owner crashed teh plane inverted and broke the head off. I stripped that engine and couldn't believe the amount of bore wear I saw, and yet it ran just fine. I have quite a few Saitos in all sizes and have never seen so much wear in an engine as that one had. I have a Saito 45 that I ran for 8 years, that shows no internal wear whatever. I have no experience with the OS 30, but I think the design is a little more prone to wear then teh Saito design, with the helical gear on the cam putting side-thrust on teh cam and a brass bushing as a cam bearing. Some power must be used up with that cam drive arrangement.

As Jim mentioned above, I have one of the first ones out and love it. It turns a 10x5 Graupner at 10,100 with no trouble. William Robison had it for a while on loan and loved it also.

Never had the OS 30, but I did have the 26. Now having played with Hobbsy';s FA-30 I throw rocks at the OS.

Sorry, the Saito is just that much better.

Bill.

PS: Regarding the wear - the OS runs in a plain steel bore, dusty air will eat it up. The Saito has a chromed bore, almost impossible to damage it. wr.

Bill,
Glad to hear it since I ended up buying the Saito. It sure is a cute little machine.

Given half a chance, it will make you a very happy camper.

Bill,
I sure hope so. I've been tagged as "hard to please" on more than one occasion!
