I'm not clicking on that link, Pope. I don't trust you.

We had a mule on our field for a while. He once tried to gnaw my tail light cover and I had to chase him off. He bit me lightly on my pants pocket once and he got hit on the head. He probably was used to kids carrying apples in their pockets to feed him. I started taking fireworks out to the field to chase him off the runway. He got used to bottle rockets and I would sometimes have to fire half a dozen at him before he got irritated enough to move. He had a bit of a mean streak in him.

Hello everyone,

I have a Saito 1.80 and I know they are glow thirsty
so my question is...
What do you recommend...Convert to CDI Glow or Convert to Gas

Thank you

John

If you are willing to sacrifice 20% of the HP, put up with the stench & fire hazard, go ahead & convert to gas.

If you want 25% better fuel economy, vastly improved user friendliness with a slight boost in power, convert to CDI & continue to burn glow fuel.

If you want 25% better fuel economy, the same vastly improved user friendliness & as much HP as an FA-220 put an FG-57 piston in it to boost compression, convert to CDI & continue to burn glow fuel. The FG-57 piston is a no modification required upgrade & you can even uses the same ring.

This was my 1st prototype built on an FA-150 case. You can get nearly the same power by just swapping the FA-180 piston for the FG-57 piston.

My suggestion is to CONVERT TO CDI & try it with glow fuel.


If you decide you still want to go to gas despite the significant loss in power, higher operating temperatures & likely shortened engine life, go ahead & get the CARBURETOR FOR THE GAS CONVERSION.

It's a Dynathrust 18 X 8. You should see what it does with the 12mm carburetor. 8450 RMP on 15% Cool :Power, 8950 RPM with 30% O'Donnell Speed Blend (8% lube)

Click on it barry.Popey do you remember months ago we were discussing how mountain oysters were produced? i reckon your missus has 'ringed you' and yours are swinging off her rear view mirror

This is an interesting read.

The compression is a Saito feature that is why its such a rare animal. I guess Saito gave it a try on a limited scale and then decided to keep going like they had been. It was a little harder to tune like a YS.

My early high compression Saito .80 will kick back and bust your fingers if you aren't careful. I once carried the airplane it was in back to the pits after an uneventful flight, put it down and turned to exchange a few words with a clubmate, then turned back to the plane and for some unremembered reason turned the prop CCW against compression. The danged thing kicked back and gave my fingers a painful jolt! This after having been shut down for 5 minutes or so. Good thing it had a wooden prop on it.

Hello,
New to the group but I have been reading a little. Currently operate a Saito 50, 56, 80, 91 (2), 100, 125 and 150.

Recently transplanted a couple of engines and having trouble tuning even though they ran great in the previous airframe.
Saito 91 was inverted, now side mounted won't shut off with idle cut. Looked at the barrel and the linkage. Linkage is free and with it unhooked the barrel still won't close off completely. Same motor is not running clean at full throttle either. Slowly adjusting high speed needle valve.
Saito 150 ran perfectly side mounted in a 1/4 scale Pitts airframe. Now side mounted in a 1/4 scale Cub bogs down anything over 3/4 throttle but runs smooth up to that point. I have checked the tank and have very short new connection lines. I did rotate the needle valve housing with the fuel port 180 degrees to make a straight run to the fuel line.

Suggestions welcome.

Jaybird

Set the initial timing at 34-36 degrees BTDC. Start the engine on the GI (glow ignition) carburetor settings. Run @ WOT & lean the HSN a few clicks @ a time (waiting several seconds after each adjustment to allow the RPM to stabilize) until the engine sags. That is your lean limit. Open the HSN a few clicks at a time until the engine sags. That is you rich limit. There will be several clicks, perhaps a quarter turn or more where the RPM won't be affected. Set the HSN a few clicks leaner than the rich limit. Now lean out the LSN as much as you can & still get smooth transition.

Here is a thread that lists FUEL CONSUMPTION for various prototype big block Saitos with CDI. Post #5 has the results listed.

Darn tooten , but please refrain from calling my rear man part as an alley ! Thankfully it doesn't get that much traffic and before you ask its a one way street . I see on the bottle it says made in the USA and because its so popular there's none left for export . Cheers the pope

I did mention that was too much information, didn't I? Now look at what happens around this place.

Pope- we have the same thing over here but from bulls. They pretty much market them the same way.

Pete- I ragged on Sigman too.

Just picked up a 2.20 glow! Also have a 1.25, .82, .62. I haven't run the 2.20 yet, but I am sure it is a beast!
