Tatone muffler internals

I decided to take it apart and look inside. The first thing I noticed before I broke it down is the wall as soon as the exhaust leaves the engine, horrible for back pressure. The exhaust then has to route around this wall where it is forced to exit through four small holes 2 wide and 2 narrow. Not the best design to say the least. I suppose you could open up the exit holes and possibly smooth the wall edges. Or... you could toss it in the trash bin like I did.

When you find your fuel mileage becoming very economical, you can bet that the muffler is overheating your engine and leaning out.  They also constantly come loose. Ron you have the right idea, in the trash can. Straps are a poor way to retain a muffler. Regardless if Enya uses them or not, it puts a lot of strain on the case.

If it hurts your ears put some ear plugs in! I can’t imagine they are required at M.A.D.S are they George? Pretty remote flying field. I flew at your old field numerous times without one. Anywhere I fly there is never a requirement to have one so it’s a no brainer for me.

Dec. 1949 MAN wrote:WE HAVE received a letter from R. H. Frasher, Jr., president of the Kanawha Valley Model Builders, Inc., of Elkview, W. Va. Mr. Frasher passes along a note of warning to other clubs which are operating in localities unfriendly to model aviation work. His club arranged a lease on a good flying field and spent over $300 in developing it for their use, to say nothing of the un­ counted hours the members labored on the project.

Following a few complaints from local citizens (doubtless “narrow­ minded,” as Mr. Frasher states), the city council took action resulting in the probable closing of the field for model use, and total loss to the club of all the money and time they put into it. Mr. Frasher thus says with considerable authority, “It would be our advice to any other club contemplating building a model field to build it outside the city limits by all means, because sooner or later someone will take it upon themselves to stop the flying.”

The complaints in the case cited above came, as have virtu­ally all similar complaints of which we have heard, because of NOISE made by the engines. We cannot understand why model fliers who are being forbidden to fly in built-up locali­ties all over the country cannot realize that the roar of motor, which is sweet music to the model builder’s ear, is just plain racket to those who have no interest in model flying. We have been urging model builders to use mufflers for a long time. Way back in our July, 1948, issue we gave full details on construct­ing several simple types of mufflers that have proven very effective.

Model builders usually start raising complaints as soon as the subject of mufflers is mentioned. They say mufflers add weight and wind resistance, cost a lot of money, and worst of all—cut down the power of the motor. Aren’t they willing to trade a bit of added weight and wind resistance for permission to fly their muffler-equipped ships in built-up areas? The other objections are totally invalid; the article in July, 1948, Model Airplane News, showed how mufflers can be built for a few cents. That leaves only the question of a cut in motor power.

Well, you doubters, even this has been solved! A prominent motor manufacturer now offers a muffler that actually increases power! This muffler is designed upon a principle used to quiet the motors of full size planes. What’s more it is small and light, and low-priced besides. So, whattaya say, you fellows who are losing your flying fields—give mufflers a trial and you will find it a sure way “to win friends and influence people” in. favor of power modeling.
