saito fa220 fuel question
hello guys, sorry for such and easy question (to some of you) Ijust got a great planes ultimate, it has a saito fa220 on it, super nice plane.
Ihave never owned this kind of engine, a 4 strokeGLOW,,I have downloaded a manual but still have some confusion about what kind of fuel to run in it.
Ihave a large moki 2.10 glow engine and run the omega 5% fuel in it,,
but what Iam reading is that since this is a 4 stroke it needs a different kind of glow fuel?? and help would be appreciated as Iwant to get this thing up and enjoy it
thanks
Ronnie

RE: saito fa220 fuel question
G'day
I run about 14 Saitos. I use similar fuel to you in all my Saitos though it has 10% nitro and not 5%. I also use the same fuel in two strokes.
My fuel is 10% nitro, 5% castor, 15% Klotz synthetic and 70% nitro. I do run more nitro in one Saito - a radial three cylinder 90R3. This motor develops very little power for its size thanks to its mechanical complexity and does tend to drop a cylinder on 10% fuel but it is quite reliable and usable on 20% fuel. It does sound amazing though which is the main reason for owning it.
I think you will be fine with your existing fuel but you could use more nitro. If you do, you will get a little more power and tuning will be a little easier. You will also invite more rust problems and the engine will wear faster.
Your choice.

Ronnie, in your part of the world you should find PowerMaster everywhere. Their 10% with 18% 80/20 blend would be perfect. As Mike and OF said it'll run great on 5% though. If they have WildCat it is great too, its all I use.

RE: saito fa220 fuel question
You don't really need to do anything special for the fuel to use in the engine. I use the same fuel in my two stroke glow engines that I use in my glow flour stroke engines too. I normally use 5% Omega glow fuel in most all of my engines. I like the blend of synthetic and castor oil in my fuel anyway. But the castor oil could cause the valves to stick if you don't use the engine for a long time.
They used to make, and still do to some extent, special four stroke fuels that had less oil content in it and it used all synthetic oil as well. But you don't really need them.
Now then some engines may have lower compression and not run well with low nitro or no nitro glow fuel, you may have to run more nitro in the fuel for those engines. I only ran into the problem with a some ASP .61 four stroke engines that ran well using 15% nitro glow fuel but didn't like 5% glow fuel. In this case the engines either or would not idle well or had problems peaking out. Sometimes during a engine break in, it needs more nitro to idle well but this is before the ring gets seated good, etc.
