So which saito radial is reliable?
Hey guys
After my FG33R3 exploded (inside) during flight, like a lot of reports here and in others foruns said they do that, wich saito radial is reliable?
I read that the 33 and 84 aren't. The 60 looks like reliable. What about the newer 90cc?
Am I mistaken or the 60 is the only one really good to use?
Please I'd like to know your opinions.

From what I have read the 84 had some real issues but after owners sent their engines to Ray English and paid him to have them modified , they had no more issues .
The 33 seems to be hit and miss. Some claim they are running fine out of the box while others had to send them to Ray for modification.
The 60 has Saito incorporating the Ray English mods into the production so they seem to be running fine.

Not sure of the new 90 but one would think Saito would be including those mods as well.

We have had several blow ups in our club as well. They are very expensive and should not be put on the market with the faults they have.
Its only us model engine users that put up with a bad problem. OS have been putting out bad engines for a few years as well. In my eyes Saito and OS were the two top brands out there but not anymore.
I would not now buy either but have owned both in the past.

I know this thread is for radials and my 60 radial has been running great in the limited time I've been running it. Has anybody been running the 61cc twin? Was wondering if it's having the same problems as the radials. I've been thinking of using it for the new RV-4. Thanks for your advice.

Here in Europe many FG60 R3 are broken. Always the same fail: Cracks in Cylinder 2. My nr . 1 is on the way to Japan (repair take 4 months!!). Nr 2 is still flying.
BUT, there is no alternative! Is there any other 60-90 ccm radial engine on the market?? NO!
so we have to live with Saito with all his fails...

If they have had soo many issues.... too bad saito wouldn't offer up an option to use a alky carb!....
Run it with methanol, and have NO MORE ISSUES!..
I may eat my words after I run mine... but the nitro versions NEVER had any of these problems that you all are having.
I am very bummed to see this ... I really am... I will be running my saito 325 and the Big 3cyl radial this summer with the stock Nitro fuel and will report back.
In all honesty, I hate the smell of gas and lover the smell of nitro anyway.

The engine was designed as a nitro engine using considerably more oil in the fuel. It has no needle bearings or even bushings on the rod ends and runs steel on aluminum so it needs a lot more oil than they suggest.
It is also designed to run with methanol which gives a very good cooling effect and allows nitro engines to use less fin area for cooling. Gas engines run much hotter and have more cooling fin area so the engine has marginal cooling fin area and needs as much baffling as possible. It adds up to an engine that will not tolerate less than perfect running conditions unlike most gas engines which are hell for stout and run well under really abusive conditions.
