Default 4 Stroke Engine Saito

Hi,
At this time I only have 14 stroke which is an older OS 82 which seems to run great.
I'm building a twin engine airplane from plans 30 years ago that was originally flown with to 2 stroke K and B 40s
1st off I assume that a 4 stroke 70 is roughly the same power?
I was also told that the Satio's are a little bit better than the OS s so what do you guys think?
The plane is a Piper Seneca twin with a 86" wing.
I was thinking of to Satio 72 s for it??
Please lots of responses looking for lots of opinions.
Thank You
Bob

Saito 62 on a SIg Four Star.
Two Saito 62's would be perfect, the numbers are not as lop sided as that in this day and age, so even Saito 56's would do the job but hard to get. OS 56 Alpha's would cost way more.

If it helps I built a 76" span twin powered by two OS FS40's. Weighed about 8 lb and flew great.

The question to yourself is if you loose one engine, will it fly on the other engine to hopefully get back to the runway? Or will it be underpowered? In which most guys stall spin it in?

The twin I mentioned above has twin tails and a long tail moment. Once airborne will fly on either engine. Many scale twins are unstable unfortunately.

I was replying to the OP. I guess that I should always use the quote option so as to not confuse some.
