JIm, I have what is my second 1.25, I had to sell the first one to pay an electric bill and you saw where I just got the latest version I had no problem with either and used full synthetic fuel in both. The new one has about 2 hours on it and runs like a fine Swiss watch. I am not a worrier and have little faith in, (me too) posts.

I doubt they are going say much since there is no problem with the 1.25. I had a 1.15 and it had no problem. I am sure you're as good an engine guy as any and maybe better than some. I am skeptical about there being a 1.15 problem, oil finds its way into and onto places where you don't even want it. (not in our engines of course) I stick to minimum 18% lube and that is full synthetic. My choice , not a recommendation.

well, people in Vermont will soon be able to grow their own "cannabis oil" for their engines, I'm betting there will be a lot around, and that many will be willing to give it away

Jim what effect may it have if you rub the oil all over a 125?

[QUOTE=Jim what effect may it have if you rub the oil all over a 125?.[/QUOTE]

O.F.,, well, I would have to guess it would feel laid-backed with the ambition of an old .32 size 4St running on 0%, while setting around at the field watching all the other engines having fun as they zip around, and then laugh if any of them had a flameout, and if any crashed it would just set there and say quietly and smoothly> "oh man,,,,, what a bummer"

BLW,, I have not called them back, but I am betting it would not do me any good anyway

That's very funny and a peaceful setting you could wreck by throwing a box of mars bars around carelessly did i read that you were running a 14x8 prop on the 115? if so you may have over revved it,what aeroplane where you flying it in?

as of now I don't own Saito, but I'm thinking about it.. but too add, I know 2St's well so I am looking good at that HP Twin, and I like the Inline thing, and I can get it ether ABC or Ringed, Standard Head or Heat Sink Heads,, I'm thinking ABC with Heat Sink Heads

so as you guys know I called Horizon almost 2 weeks ago about this lubrication issue and they have not called me back, you also know that I said the guy told me he could not comment about the problem because he never heard about the problem,,,, well,,,, that's a funny thing that he has not heard about this problem, because if you open the link I posted to Horizon's "Saito Display Page", and scroll down to the "Questions Asked" you will see a complaint about the very same problem I asked about hummm

now watch that complaint disappear..

https://www.horizonhobby.com/storefr.../saito-engines

PS, also note that Horizon does not answer questions that are asked,, why have a place to ask questions if you are not going to answer them

I personally never did believe that there was a problem, I had a 1.15 for a couple of years, it was the first engine I ran on full synthetic and I designated it for that. After sitting for days the moving parts would stay wet with lube.

that's like the OS Hyper .50 Heli engine (Blue Head) and their rear bearing rusting out, some did and some didn't, I have 2 of them, my first one rust out in less than 3 gallons, and my 2nd one rusted out in less than 2 gallons, while my very first OS .50 SXH (Silver Head) engine from 2002 ran for 4 years with 7 gallons threw it yet it never rusted out, I burned the piston out of it when I finely switched over to 30% ooops

people (including me) came up with all kinds of reasons why those bearings were going bad so quickly, well they were un-badge bearings, so I say today that OS was just buying cheap bearings


so, with Satio, a few people have had this lubrication problem, and what ever it is, there is a reason behind it, it would be nice to know what that reason is before I buy, I don't think that is to much to ask of Satio before I shell out close to $350 to them,,, if the 115 was a $150 engine I would just buy it and take it apart, drill & tap a hole for a plug and oil it every once in a while

I have been on this site since it was called RCOnline years ago and have only seen one claim on the dry cam issue. Barry may be able to enlighten me if I'm wrong but I don't think so. You're hint a drilling a tapping an after run hole is what I do to Enya's to keep rust out of the cam box.

That seems to be a common issue with the enyas . You would think they would have a handle on that unless its some sort of user error .

I had aggressive opening ramps ground on the cam for my 2006 Charger 5.7 Hemi.

It gives some of the advantages of more duration at lift yet allows ample closed valve timing to generate good cylinder pressure to enhance low RPM performance. It isn't good practice on the closing ramps because one doesn't want the valves to slam shut.

I've outlined the process I use at the start of each flying season before and I've never had an issue but I've heard of quite a few other folks who've ended up with dry camshaft bushes because they perform no manual lubrication or think that oil dripped down the pushrod tubes will make its way into the cambox (which it wont).
This pre lub is exclusively for the Saito 100? This engine has design problem to need manual lubrication? I question because my other Saitos I never do that and running for years. And with this lub process the Saito 100 will run a long time?

This is one of those "sore point" issues for some who are opposed . After many years of observation of Saito engines from all around starting right after Satio 4S first appeared, I now move the vent forward on all of my own and most of the engines I service for others. I do this mostly when taking the engine apart for servicing. Started doing this early on when taking the original Saito 4S engines apart. Gear and cam wear were often noticeable. For the sake of experimentation, I began moving the the vent to the cam box. Made sense in every way; Instead of the majority of the oil taking the easy way out the rear, it now was passing forward to benefit the oil hungry cam, lifters and bearings on its way to the atmosphere. When after oiling, you now displace the moisture and spent oils with fresh ARO. Turned out to work very well, cam wear even after twice the pre-change run time was zip. It wasn't long after that before Saito took to moving the vent forward on many models. Not like it is a matter of imminent failure. Some who are opposed will try to paint it that we are inferring that, not in the least! Just offering real reasons and real experience. You can decide for yourself.
Yet over the long haul, with a huge sample and range of Saito engines, the move forward has been worth the effort in every case . I still have my very first 1979 or 80 Saito 30. Replaced the original cam in 1982. That cam is still in that engine and in great shape. The vent is still in the front as well.
