Status: offline 		I have a question for anybody that will help.
How much thrust does a Saito .56 have?
It is the newer one. I have a Edge 540 with a all up weight
of 5.5 lbs. What do I need for a prop to make this engine
hover this plane? Or is it to small. Any advise would be great.
Thanks Fred

P.S If any body knows please let me know.
Thanks again

Status: offline 		I run a 14x4w on my .82a does a great job 3din , I posted a video a page back that plane is flying with an .82a with a MAS 14x6.

My Extra is 5lbs 6oz dry (300cc) and vertical is unlimited just a hair above half throttle.

Awsome little powerplant!

Mike.

Status: offline 		I want to share something that happened to me last Sunday:
I have a Venus 40 plane which had a Saito 72 (I had some death sticks) I changed the engine and bolted my Saito 82 and flew it last Sunday. I had three death sticks on my three flights.
Some fellows came to me to see what was happening some of them telling what I should do to avoid the engine from stopping.
After some research the result is that the tank is a bit higher than the center of the carburetor, no problem and I will fix it soon.

But what resulted in a very interesting comment is what I want to share.

A very close friend of mine (Good experienced pilot, builder and skilled with the engines) came to me and, not knowing about the tank issue told me that the engine was overheating and that was the cause of the death sticks (Yes the engine was overheating), then told me that I could manage set the valves in different manner to avoid the overheating situation.
Here is where I need you opinion.
My friend said that I should open the gap of the intake by two points (or half more the stock) in example:
Gap recommended by the manufacturer is .004 inches
My friend suggests .006 inches

Also told me, that the exhaust valve should be twice the recommended gap. Example:
Gap recommended by the manufacturer is .004 inches
My friend suggests .008 inches.

The effect of opening the valves is letting in more fuel and assures that all exhaust is off the engine before the new stroke which would lead to a cooler operating engine.

So what do you all guys think about this?

I think that a larger gap results in opening the valves LESS than a smaller gap. I don't think this is a good idea at all!

Status: offline 		I just bought a new rear bearing for my Saito 80. Need advice on the best way to install the bearing in the case. Also, I've noticed that the old bearing is unshielded, whereas the new bearing is shielded on both sides. Is this just a running design change or are there two different bearings depending on engine series?

By the way, Horizon was friendly, helpful, and very fast on delivery.

Thanks in advance,

Dick Fischer
