The Tygon tubing will melt and burn.

Exhaust extensions do not have a material detrimental effect on four strokes.

Silicone tubing seems to hold up. Some people use metal.

We:

Exhaust extensions/diverters are made and sold for glow engine mufflers. Look in the Tower or any other catalog and you should find what you are looking for. Dubro makes one called an "exhaust deflector". I have used them on two cycle glow mufflers and they work well. It is as easy to use as putting it on the muffler exhaust, divert to the direction you want, and secure it with wire ties.

I just finished doing a cleaning and valve job on a couple of high time 120S's. In the gasket kit there is a little bitty o-ring that I have no idea where it goes. Didnt see it when I tore the engines down. Doesnt show up on the parts break down and, naturally, horizon doesnt give any descriptions. Anybody know what its for?

I wonder what Spark Plug the FG-36 uses. My experience with spark conversions on 'methonal' fueled engines is that the plug doesn't last long. My hope is that the plugs will be readily available and fit existing Saito engines.

WOW thanks Ken! I guess I'm flying tomorrow morning

Edwin,

Check the throttle body where the needle valve goes in. I have seen them there.

So your getting about 2 hours out of a gallon of fuel. If I run that much fuel through my new 180 and do it right it should be well broken in by the time Montana flying weather arrives. thanks for the response. Ron

Ron McK...

I've heard that the rule of thumb is 1 oz burn per cubic inch per minute at wide open throttle. That agrees with Michaelh's 8 flights of 11-15 minutes on a gallon, cause he's probably not running WOT all that time. More likely averaging 1/2 throttle.

Ron,

Put some skis on it! Ha.

Need some help putting a 72 back together. How do you know if you got the timing correct? The engine was taken a part where the bottom of the block and the top of the block meet. Did that make sence? Can I just slide the bottom part with the piston still attached to the crank into the sleeve?

Thanks for the help guys

There is a mark or dot on the cam gear. This goes towards the crankshaft when the piston is at top dead center.

yes, you can slide the cylinder down over the piston with the rod attached to the crank pin

Valve adjustment is .002" to .004"

The small end of the pushrods go towards the rocker arms

Be sure you have the correct side of the rod towards the counter weight of the crankshaft

I use a piece of fuel tube on the crank case vent and run that into a piece of thin wall 1/4" tube and then out of the plane. No problems so far and I have run about 15" extensions using this tubbing. The fuel tubbing is about 2 inches long and the rest is 1/4" tube to the outside. Engine runs fine and no problems with oil coming out where it shouldn't.

mred33, that's exactly what I was trying to say in post 9449, two pages back. Except, you said it better!!

With your method, the oil can't plug the line

colecas, That sounds right. That's good information. Gives a good basis to figure fuel requirements. Thanks, Ron

Nope! Too small for the needle valve o-ring.

There's one on the LSNV. It is rather fat.

My Feedback: (2)

This o-ring is about 5/64" dia and around 1/64" thick. Very thin. Too small for any needle valve. Has me stumped. Couldnt find it on the engines when I disassembled them. According to the horizon charts, this gasket set is used on all the varients of 120 including the dual plug. Having never seen a dual plug or even a parts break down, I wonder if its used on that one somewhere. The gasket set has a backplate, both rocker covers, cam housing, and aluminum intake manifold gaskets along with this itty bitty tiny o-ring. In this picture it looks a little bigger than it really is. http://www.horizonhobby.com/Products...dID=SAI120S32B

Hi Guys, I just came across your Saito Club and thought I would ask for help/opinions regarding my beloved Saito 180GK. I have been flying this 180 for a couple seasons and it was running beautifully. ...I mean 1 flip starts, it would idle forever and yet would give me fast smooth response instantly when I wanted it. Well as things go, flyining a low high speed inverted pass over the runway and went to pull up vertical (giving the down elevator as I should and sudddenly the plane snapped to the left , and hard as tried as I could I was unable to save the plane and my beloved plane and my perfect Saito 180 went in nose first into the ground. There is various damage to the engine that I can repair. But the crankshaft is bent,(tho slightly)none the less it needs to be repaired...My question is how hard is it to take the 180 apart and replace the crankshaft and put everything back together again.....OR should I just bite the bullet and send it to Horizon and hope I won't get raped on the repair costs. THANKS dENNISd

Hello Edwin,

I wonder if your O-Ring might be metric. This may be overkill, but you could go to www.mcmaster.com and type O-Rings in the Search box, then go from there. Read the "About O-Rings" portion to select the type of O-ring that will stand up to fuel, and then search for your O-Ring. You'll have to buy a bag full of them, but they'll be cheap. While you are there, take a look around for things like Aircraft drills, or T-handle hex keys.. It's a tool house but there are a lot of things that a modeler could use, such as a 1/4"-32 tap or die for glow plug threads, etc.

I'm guessing that if you measure your O-ring very carefully with calipers, it might turn out to be a metric size...

Just my $.02

doubledcom,

I've had my own Saito's apart and they are not difficult if you do things in an orderly fashion. Keep things like intake pushrods, etc., separated from the exhaust side, mark the piston & connecting rod for proper orientation, etc. The usual tricks.

But, if you suspect that the crankshaft is bent, maybe the folks at Horizon have a trick or two up their sleeve for getting that out without damaging the casing (which might also be bent). They would have the dial indicators, etc., that the average person doesn't have. I haven't heard anything, good or bad, about HH service.\

Again, as in the message above, it's just my $.02

Can anyone give me recommended fuel line sizes for the 180, 100 and 82 Saitos.
Thanks in advance

They all seem to run fine on medium tubing.

Some people do run large tubing on the 180.

I should have explained. I didnt need the o-ring. Just curious what it was for. The carb on both engines are perfect and in great shape. Im pretty much speculating that its used on someplace else, not on this engine. Either way, my engines are good to go now.
