I was very surprised to find that no machining is performed to create the valve reliefs, just cast and left that way.
Glowy stop pulling the fa82 apart,then you'll never see that stuff

Just a thought Jim, maybe siphoning is a more common problem on larger engines where needle settings are opened wider? All my 4 strokes are .82 or smaller.

Sleeve for possibly reducing the diameter of a Saito 120 carb?


Came with Blue and White box Saito 120.

I was hoping someone here would know, it's a question on the other network, I sort of broadened his search for him. I'll get a picture of the box, maybe that will help a little.

I have experienced siphoning with my Saito 65 mounted inverted on a Kyosho P-40. Make a mess in the cowl so I just gas & go typically. This year I plan on swapping it out for an fa-56 (the 65 was too heavy) and if I continue to have the problem I’ll add a Cline regulator to the setup.

I have an excellent running FA56a, makes the full rated .90 hp according to my thrust calculator. PM me if interested.

Or if perferred I also have an excellent running FA62a that makes the full rated 1.0hp. Same case size as the 56.

Thanks for the offer Glowgeek but I already have a 56a looking for a job. The 62a is tempting but I have a NIB OS 62V to fill that niche as well.

To fill in my lineup, I bought a used fa72a I want to compare to the 82b I should receive soon.

I was hoping to help with this one as I have the same engine with box and instructions but there is no reference to an insert sleeve as an option. Perhaps they’re random bits thrown in with the engine. The only carb I’m aware of using a restriction sleeve is the OS 7D carb.

A fella in our club has a 62V, it makes .20 hp more than either of my FA62a Saitos. His 62V swings an APC 13x6 @ 10k peak.

siphoning
so some people have the problem and others do not (with the same engine), could it have something to do with the fuel or fuel additives ??

Or your club has angered the local Woodland sprites. They can be very unforgiving until reparations are made.

I bring 3 or 4 planes to the field to fly. I pretend like I'm going to fly the first one so the gremlins and pixies jump on it while I'm secretly flying a different one.

Trees are like rattlesnakes, they can strike out 3/4 of their body length. I've seen it too many times to deny it. When I go to fly-ins I always ask where THE tree is, there is always at least one.

At the last out of town fly-in I should have asked where the chiggers were. Not fun.

At our field, the burmuda triangle gets em lots of times, so I keep my little Saito buddies clear of those distant HTL... One thing to lose a plane, quite another thing if it has a Saito on it.
My last oot warbird show was rain off and on for four hours, on a panhead. Then to arrive with to much wind to fly at the facility. Just to turn around and roll back on the rain slick, black pavement after dark.
I did have glasses and leathers though. Kept the chiggers down.

I lost a park zone spitfire to a rattlesnake tree once. I thought I was inside the tree line but either my depth perception was off or the tree reached out to grab it. Lesson was to keep the line of sight above the tree line.

Rudolph, I was in Perth once when I was in the Navy during the 80’s. We had a 5 day port of call on the carrier USS Constellation. Beautiful city! I still remember the boat tour we took up the Swan river to wine country. Everyone was so friendly and hospitable. The cabbies made sure we knew when the America’s Cup was when Dennis Conner briefly won it.

I have come to the conclusion the AMA is useless. It's bad enough we are required to register with the FAA, now we have to disfigure our scale birds with the stupid number. Screw them, going to make the number so small you need a magnifying glass to see them. They say has to be outside, they didn't say how big!

Good to know Glowgeek. I heard nothing but good reviews in the 62V so when I had the chance to buy one at a great price I couldn’t resist. It has the look of a Saito which is perhaps why it looks so nice. Powerwise, looks like it falls between the Saito 65 and 72.

My 82b arrived yesterday. What a beauty!

back when I was looking to buy a Saito FA100 I found a bench ran OS 95V for a good price, I found prop/RPM numbers on both the FA100 and 95V, in "those" numbers I saw the Saito turned the APC 15x6 faster than the OS did, but the OS turned the smaller prop faster, sorry, it's been a long time, I can't remember what that smaller prop was. never the less, that end result with the 15x6 is one of the main 4 reasons why people will buy the Saito over the OS,

now that the Saito/OS thing has been brought up again, I have to say that I have no idea why used OS engines hold a higher resale value over a Saito of the same size, I have seen it many times, and it just makes no brain sense to me

I don't get the used OS prices either. The only used OS engines I have been buying have been smaller 2 cycle engines. I have been amazed how cheap they are selling.

In their case, one and the same.


Maybe the OS hold their value more in the same way Toyota holds their value. They may not make a great car, but they last a long time.

You've got some beauties for this coming season. They both look new!

BTW, your bench is WAAAY too clean to be useful......

I recently sold an O.S. fs-70II I had on a profile Katana in favor of the Saito 65 which I purchased NIB. They both have the same relative weight & power. The fs-70 ran perfectly fine, is a mild manner engine and unintimidating to start. The carb is easy to tune as well.

Maybe it’s me, but the Saito 65 requires more caution when starting. It’s a beast! It kicks a lot more and probably not fully broken in and tuned yet. I only have a few flights on it with my P-40.

So if one one is looking for lighter weight, raw power, great reliability with good looks Saito is the way to go. But OS has a place as well due to their ease of operation.
