I have yet to see it leave a skin on anything, I use it in all my engines, on my drill press tables, the brake and shifter rods on my Harley, saw blades that I'm not going to use for a while. If an engine has gelled castor the CX will dissolve it and leave the surfaces shiny unless there was previous rust. Castor will not gel in its presence. It does not ruin glow plugs. Its the only thing that keeps my PAW Diesels from getting gelled stiff because Davis Plane fuel for bushing engines has lots of castor in it. I use the Plane fuel because of the steel on steel piston and liner.

It's really fun to inject your after run oil into the breather tube of a Sait when using an aerosol can that's pressurized like Corrosion X, or outboard fogger oil. It goes in with some force and pushes the piston up to TDC as the lube goes in. With my outboard fogger can, I glued a piece of alum. tubing right over the little red straw that comes with the can and that fits snugly into the breather tubing. The electric guys don't know what they are missing out on!

To blw, Thanks for "drafting" me into the Satio club, It's an honor I won't take lightly(after all I only own one saito engine but I do love it). I got back last night from my first attempt at a pattern event that was over in your neck of the woods (Alabaster,Al.) and just read the thread. Nice people over there at the Alabaster RC Association. I hope my "secret cleaner" tip is helpful to some other modelers. Good luck and good landings,52larry52,...SAITO CLUB MEMBER #685

Hey Ern, when the piston is at tdc with CX pressure, pinch the end of vent tube and try to turn the crank, I'll bet you can't.

Ernie Misner

Hobbsy, I think you are suckering me into blowing the breather tubing off of the engine and giving my face a Corrosion X beauty treatment....

Is the Saito 125 really lighter than the average 2-stroke 90? Saito lists the 125 with muffler as 24.69 ounces and Tower lists the OS 95AX as 26.28 ounces with muffler. I'm amazed if the Saito actually is lighter than a 90 2-stroke. Is this possible?

Thanks,

Ernie

Ok all  I have found out why my data here in Oz is different to you lot.
It would appear that all good people in the USA get their info from Horizon Hobbies (the Saito dealer) and we get ours direct from the factory via our distributer.
And guess what there is a few differences.  I looked at a Saito site (probably generated by or associated with Horizon Hobbies) and this little bit of info popped up.
Thus I guess while we are all reading the same book so to speak it would appear as if there are different versions out there.
Interesting Huh.

Ernie Misner

Well what does your Oz site say about the all up weight of a 125?

Thanks,

Ernie

Specs are the same EXCEPT you have to read the adverts, some people don't include mufflers others do but if you really want I will get the data from my printed data the next time I am in my shed (workshop)
From my own point of view I agree with you Saito 4 strokes are generally heavier than the equivalent 2 stroke and better as well

Im fairly new modeler, but I have A saito 100, 120 and a 91 (os 4stroke) and I totally love 4 strokes better than the 2 cycles! I have several 2 strokes but much prefer the 4. Just my 02cents worth..... Stef Rockford Il.

There is a new cylinder on the 1.25 with either more or larger cooling fins, it is bound to weigh slightly more. Jim will know for sure

The new "B" cylinder doesn't seem to weigh more. There's more and wider fins but they are thinner so there's no weight gain. The valve angle is greater. Seems to have a little more power.

It is basically the same cylinder used on the FG-20 with the machining a little different.

Have any photos of this new cylinder, good fellow?

Hi guys,


I finally bought and received my 150GK !

Does thins type of engine have a lot of vibrations if mounted on a regular plastic/alu mount ?
And does mounting it on a Dubro soft mount help ?

Tnx

w8ye

My Feedback: (16)

Just mount it on a regular mount like the Great Planes 120 size large mount.

I got some pictures on another hard drive around here some where?

Just look at the Saito FG20 gas engine. They look pretty much the same except the FG-20 has a bunch milled off the bottom to raise the compression.

At first glance you will notice the fins are shaped different on the front up by the valve covers. Other subtle differences like a little more meat around the exhaust pipe boss.

There are pictures on this thread if you care to search back about 50 pages

Saito FG-20 thread, post number 15 show the gas and glow version of the "125"

jay1st

ok, so a regular nylon mout is good enough !
And what about the engine being inverted in a cowl (sea fury) ?
It's my first big 4c, so how am I supposed to prime it ?

That's a lot of Qs waiting for As, but that big engine is a bit stressing me !

w8ye

My Feedback: (16)

To prime a Saito 150 enclosed in a cowl.

Open throttle
Put your finger over the end of the muffler and turn the engine through compression a couple times and it will force fuel through the carburetor.

mike early

To prime it, open the throttle a bit and cover the exhaust pipe with your finger and turn the engine over a couple of rotations. This will create muffler pressure to push fuel into the carb. THEN apply the glow igniter and start 'er up.

jay1st

That seems easy enough !

I do the same on my 2c engines.

Tnx for the info

The different 125 cylinders. The "B" version has the parts on it The older 125 cylinder had the threads stripped from the exhaust outlet.

Oh yeah! now I remember.
