I have a NIB Saito Fa 40 that has an exhaust like your OS FS 20. Except, there is a pressure outlet on the exhaust tube. My OS FS 20 has the muffler. When running the OS on the bench I did not use exhaust pressure and the engine still ran very well. The little four strokes are so quiet and have such good fuel draw I don't think the muffler is really necessary.

Hi Bob, Did you buy the silencer separately or did the engine itself bring it? In my case the manual says it is optional.
Anyway I agree with you, it will surely work without the pressurizer correctly, the question I ask myself is, so that then the option to pressurize the tank? ... maybe for acrobatics models where in many occasions the fuel tank Need pressure to favor the power of the motor, for example in sharp maneuvers of closed angles and climbed vertically? ... is possible.

My manual:

Mauricio,

I bought the engine used. It came with the muffler. I do not know if the muffler originally came with the engine. I believe the OS FS 20 uses the same muffler as the FS 26. That might make it a little easier to find the muffler. I don't know if the .26 size is still in production.

Hi Bob, thanks for the info. Do you buy it from a colleague ?, surely your manual may be the same as mine and who sold the engine may have bought the exhaust chamber. It is not a problem, I even encourage you to manufacture it, I would almost say artisanal if necessary.
Could you please place the measures of diameter and length of the camera ?, I will only take it into account if I see that the application is necessary.
Since we are, I comment, that these are other models that I am also interested to manufacture ....

Thinking of putting them together for Cox.

What do you think, my friend?

Mauricio,

I will get some pictures and measurements of the OS muffler either today or tomorrow. I will also draw out my idea for making a muffler that I would use on the Saito .40.

dear friends, here I am resuming this project... I clarify that my head is not completely focused but I want to work with some model and I feel that I will become more eager as I progress, of course I will do it with time so please I will walk here...
I also want to bring here the link of my friend Happydad who had also started working on a similar model, I think the memory of him will also accompany us: https://www.coxengineforum.com/t14189-all-star-biplane-for- 020?highlight=all+star

So, here I start with the choice of the engine, well, a Cox, a G-Mark and an O.S....they are all applicable to this model and the Cox would easily take it, it is the lightest and most powerful, on the other hand the O.S. .10 FP, it is also a safe and powerful engine, it is the heaviest of the three, lastly and I think it will be the one I am going to use, the G-Mark .12 twin cylinder, it has an intermediate weight between the Cox and the O.S. and a power similar to the O.S. but what catches my attention the most is its 2-cylinder micromechanics and I think it would look beautiful on the ACE BIplane, I think it would be a harmonious whole.
I'm still thinking, but I'd like to apply the G-Mark .12 here.
I have never ridden it, it is simply 0km...to be continued...

Hola Mauricio!! . I remember the advertisements for the All Star Bipe when I was in Jr. high school….. It seemed very exotic at that time and far beyond my reach…. I never built the All Star but a few others over the years from Ace R/C, They all served well….. My first radio set built from a kit was from them too… I know you will bring out the maximum potential in the All Star Bipe and I will be anxious to see it …. One of my Ace kits that still flies continues to wear the sticker from its original radio equipment….

Hello Mauricio , That G-mark .12 Twin is going to look Good on the plane , In for the ride I miss Happydad he was a good soul !

BRAVO!!! @Happydad would approve.. I am sure! Happy "New Year" also Mauricio my friend!

I look forward to "walking with you".

Thanks guys!...it's a very nice project, it will go slow because I'm slow haha...I'm doing this very slowly...
This kit was cut by an aeromodeler from Argentina, it is not original, it has some modifications, such as the fuselage itself that is assembled in parts and the wings are made of wooden ribs, also the upper wing support has another way of mooring, but not yet I realize exactly what it is like, I'm going to find out...here we go!
Roddie!...happy new year friend!
