Yep. It works really well, but as I expected the needles are not nearly as sensitive as they are without it.

Hi,
I have a bearing question.
My 1,5 years old SA180 has about 10gallons fuel through it and runs very nice and smooth. The other day I just hold the tip of the propblades to feel if it was any radial play, and yes is was[], seems to be the rear bearing getting loose. The engine does not make any bearing noise yet when it runs so what do you think about that?. Should I replace the bearings now or run it until I can hear some bearing noise?

RVM

I'd just go ahead and replace them.

Well Bill, I think I'll wait for a good used one as you suggest. I don't have a problem tackling a 2 stroke but I've never even touched a 4 stroke let alone a Saito.

Thanks to all for the input.

I'm installing a Saito 82 in a plane that has the fuel tank back on the CG which is 10" behind the firewall. Will I need a fuel pump?

Yes, you can use a pump or a regulator (such as Cline or Iron Bay)

my god ! has anyone seen a OS 120 AX run, impressive, but i'll stick wit my Saito's !

Thunderchild

I'm with you sticking with Saito [>:]

Someone please publish video of that gasoline powered 220 Saito (featured at the Tokyo Hooby Fair) in full song!!

Woo Hoo!!!

Might as well change the bearings now than later. Bad bearings causes higher rate of wear on other parts

Mike,
Is it necessary?

Intake stacks....I ordered one for my Saito 45 approx 9 mths ago & I'm still waiting.......despite trying to source one from 2 different hobby stores here in Australia. Have also tried Horizon Hobbies but they do not ship outside of the USA.

Can anyone point me in the direction of a hobby store (any country is fine) that has Saito intake stacks AND will post to Australia? I'd also like one for my Saito 65 as well.

Phil, if you're running the tank that far back, you will need either a pump or regulator. I've used the Cline reg with great results. You can get more info here http://saito-engines.info/body_pumps.html

I really like the Iron Bay unit.

My Feedback: (58)

I have not used the IB reg, but I'm wondering if the diaphragm is a standard Walbro part, like in the Cline?

The Iron Bay uses a Schrader type valve instead of the Walbro needle and seat.

Jim, any idea who is the oem for the IB diaphragm?

Guys I have a question on the Saito 300TL. I have the tank back over the CG and having problems getting the engine to run. Saito makes a pump (really just a needle valve) that ships with the Saito 300 TTDP which is the twin carb version. The pump comes with two, one way check valves that are supposed to be mounted to the crackcase. The instruction manual shows the pump mounted to a 300TTDP using the puke tube. What is confusing is that the rear case cover for the TTDP is shown as the same part number used on the 300TL, single carb. There are no mounting holes for the check valves on that case? The way this pump works is a simple needle valve that sends an adjustable perssure source to the tank, and lets the excess pressure vent to the outside via a third line. Here is my question. If you diverted all of the pressure to the tank with minimal venting to the outside, how does the engine find enough air when it tries to "suck" air back into the crankcase? I suspect that they include the two one way check valves to be mounted in the crankcase, and provide pressure without interferring with the "vent system". But in the manual they show it attached to the puke tube. Does anyone have experience with this engine and pump?

One check valve is to be used just to let air into the crankcase. One side is to the atmosphere and the other is to the crankcase.

The other check valve is used to keep pressure at the diverter valve so there will not be any suction at that point. This is the one with the tubing barb on one end

These pumps are nothing but trouble unless you use to Cline or Iron Bay regulators with them.

I see what you are talking about on the cover. Same number for both engines and on the crankcase also.

You could use an alternate method to pressurize your tank?

Some people have not used the saito check valves but installed an after market Formost check valve between the diverter and the vent on the tank.

Thanks guys, now the more complicated question Should I replace them with Stainless or Ceramic bearings ?

Hobbsy

My Feedback: (102)

Here is my Saito 1.30 with two complete Clines, it works like a champ.

XJet

When mine go, I'll probably just go for stainless. The original Saito-supplied bearings are pretty poor in terms of their corrosion resistance and metalurgy so stainless will be a *big* step forwards anyway.

If you want *maximum* performance then ceramic will give you a *small* edge -- but even at RC-bearings.com prices I'm not sure I could justify the difference.

RVM

I'd go with the ceramics just for the longevity.

Does anyone remember the discussion and pics of four-stroke engines with insulating material wrapped around the intake manifold of many years ago? I'm not sure if it was on RCU or its predecessor.

Icing was determined to be a problem and the insulation wrapping appeared to have a positive effect. I never experienced icing, nor using insulation, but some folks were convinced enough to incorporate on their engines and they swore by it.

I am not sure if those engines were Saitos or not, to be fair.

I have more icing trouble with my OS 91 Surpass I engine than any others.
