Hello all, first post for me. Has anyone else had problems with the muffer adapter breaking, while having the stock muffler connected to it? I had it all put together and while trying to set the carb adjustments, the adapter broke off at the male threads leading into the head of the motor. After receiving a new one, I noticed that there was a notice in the package that said not to attach stock muffler to adapter, because it was too much weight. Has anyone figured out a better exaust combo for this set-up? Thanks in advance.

Tony.

Tony,

I'm not exactly clear on what you had happen. I have a Saito 1.80 in mine and just used all the stuff that came in with the motor, the steel male-male 'extension', and the muffler. No issues to date.

Craig,

Thank you for your response. The adapter that I am refering to is on page 27 of the manual. It is clearly pictured on step 7. Also, did you have to open up the front and bottom of your cowl in order to get the 180 to run correctly. Anyone else with experience with this combo, please feel free to chime in.

Thanks,

Tony.

That's the 90 degree adapter, which I am not using on my engine. It was out of stock so I have the stock exhaust exiting on the bottom of the right cheek cowl. I do have one coming and will try it when I put the new cowl on.

I would not recommend using the stock muffler if you are going to use the adapter. I attached the stock muffler to the adapter and ran the engine for about 8 or 10 minutes, and the adapter broke off at the male threads entering the head of the motor. I ordered a new adapter, and when it came in it had a note attached saying not to use the muffler with it because it was too much weight.

Thanks Tony. Adapter came today and as you mention it has a note in the package saying that it's designed for use with the flex pipe.

let me know how you come out with you're exaust, and i'll post my results when I decide what to try. Maybe between the two of us, we can save someone else some headaches.

Thanks again CRG....

I assembled a Sundowner for a friend of mine with a Saito 220a for power. I used the 90 deg. adapter to get the exhaust exit out the bottom of the cowl. I ran a brace from the end of the muffler to the fuselage. That takes the load off the 90 deg. adapter and so far it is fine.

I installed the engine some 15 degrees from horizontal and left off the upper valve cover to avoid putting a hole in the cowling.

I believe he is running an APC 16-14 - it is fast.

I don't have any pictures of the setup but it is quite easy to install a brace.

Thank you Ed.

6.5 I also ran the 180 with the adapter. Mine did not break until in the air on fourth flight of the plane. Totaled I just couldn not get back to field against wind. I let Horizon know of this. I got my Sundowner as a pre-order so it was one of the first ones. There was no such tag in the package of the adapter at that time. Even though Horizon knows this could and will happen with out using the different muffler they would NOT stand behind the plane. The did send me another adapter and a cowl for some reason but would and have not sent me the fuselage. I saw when it broke and the muffler actually fell out of the cowl. This is the only thing that Horizon has ever done to buzz me off but when you lose this type plane to a manufactures faulty parts then it is there fault and not the consumers. I may have been one of the guys that got the tag put in the adapter pack as the E-Mail I sent ask them if they had had problems and if not maybe they should check the adapter as mine had broken and others might do the same as it did and has. The Plane actually sat for about 6months as I was just not experienced enough to fly it. When I felt I was and had finally started flying it well 4 times and into the ground because of the adapter and losing fuel pressure when muffler came off (deadstick) down wind with a heavy bird not good at all. Hope they see this and will finally do what they should and replace my fuselage I want to put a gasser on it. Well actually the entire plane i would suppose lol. Hard to fly without all of it.
Horizon if you see this do what is right. Before I flew the plane you already knew of the problem but did not let the folks that had ordered one earlier know of the problem Kinda like a recall on your cars. I am not going to quit them but sure left a bad taste in my mouth for sure.

Wonder why Mike or anyone has not responded to this post. I feel that Horizon, Hanger9 one of them owes me a plane. If this type thing happened in anyother entity they would most likely replace the damaged property very quickly. It is not like they did not know that this part would break and could lead to you losing your 1200.00 plane. Makes me angry that they have not stepped up and done the right thing. Also that we are being ignored on here. That to me just shows that they did infact know this product was and is faulty. The expect for you to have to buy different mufflers NOW but nowhere today does it say anything about using this part makes you have to buy other parts to go with it. Bait and switch is what it is called. Advertise a product then change everything stating this product is only to be used with a certain muffler that is 50.00 on top of the price of adapter. Or that the product is infact inferior and will not work as they say it will or would. The sell the product to you then you find out that you cannot use it UNLESS without stating this somewhere with the Sundowner specs. Mike what is Horizon or Hanger 9 going to do?
Horizon other than this has been great to me. But on this they dropped the ball from the begining and won't do anything to pick it up. I have sent several e-mails to them and will continue to do so every week they will get tired of me sooner or later. But i know in my business that if i sold someone something that actually cost them to say lose there garage door I am responsible just as H.H or H9 is on this adapter that did not have any amendment inside caused the crash of my plane by breaking and falling off in mid-air. Hanger9 or H.H had flown this plane extensivly during tests and for sure they knew it would not hold up but sold it anyway. If they did not know there would be no amendment in the package as there is NOW. A recall is all it would have taken or something such.

Learn how to fly and how to maintain them !!!!!!!!!

Lambes seems were from the same town. How about you show me better than you can tell me. Nothing I have done caused the adapter to break on my plane. There were no amendments with the adapters when I purchased mine. How the heck do you think maintance would have prevented something from breaking while it was in the air. They know now that the part is faulty and say so. They however don't want to take any blame.
When I dumb thumb a plane into the ground I am the first to admit so. But when a part breaks such as this one it is extremely bad. I can tell by your post that you DO NOT own a Sundowner so don't know why you would chime in to begin with. This was a faulty part if used with the stock 180 muffler and also the recommended part to use with it. So were did the learn to fly and maintance come in. This plane die in the air and your not way up and already headed towards the landing area you are not going to get there. It is heavy and once dead slows down way fast. I did everything I could to get mine back including diving it twice to get air speed but it was not enough to overcome a head wind. I am sure that with the vast knowledge you have that for you it would have been a snap rofl. But not for little ol me.
And still Horizon Hobby should be responsible for selling faulty parts. I suppose they should have done a little more research on this adapter before making it the ONLY way to keep from cutting the cowl. I also waited on mine but at that time they did not have any warnings with them and was the required part that they recommended be used. So there smarty pants.

Well Tony seems this is one post they are staying away from. On the other hand this time of yr. maybe Mike is busy. Sure would like someone from Hanger9, Horizon, Designer someone would say something.

To be honest I'm really not sure how to address the question for a few reasons. One is, and please dont take this wrong, but this forum isnt product support for Horizon brands. I'm here to help with general modeling questions and lend my experience to help where I can and answer what I can about any and all models.

Dont mean to hit and run on this one, but I will be at the IMAC NATS next week so I'll be off line.

The latest edition of the adapter comes with a statement that it is NOT intended to re-route the stock muffler.

I had one last three flights and one which didn't make it off the flight line.
The 90* adapter is to route the Saito flex pipe only.

I had to have some machined for that purpose. The Saito mufflers are heavy and that is a long lever arm!
After having them machined I also changed to a much lighter muffler.

BTW as a far as anyone owing you anything ______ simply not so!
Full scale aerobats, race cars (fullscale) and models are under "normal use" only.

That "normal" does not include what we do or what the full scalers do or even the 'Racing' that full scale race cars do.
I can think of nothing which is 'guaranteed' during extreme use.
In addition I am not aware of a single warranty which does not rule out ancillary loss.

Every single time we take off we are rolling the dice. That's part of the game ____ always has been probably always will be.
I don't like it when the inevitable loss occurs, but then that is one thing which makes the game (and risk) worth taking.
No possibility of loss = big reduction in the challenge. That is what keeps most of us coming back.

Mike apologies my question to you was did Horizon know about this. Is this not one of your designs? If so then and I asked this question previously to you about keeping the stock muffler in cowl without cutting. You responed about the 180 and how it performed. You at that time I am sure was using the setup that was recommended or your take on it would have had no bearing on the recommended setup just the one your were using. And that setup(saito 180) at that time was using the adapter with the stock muffler. Remember I got my Sundowner ordered before they came avalialbe. While you were still testing it.
Thanks and if this is not something you can answer I would think that you do know the appropriate people to respond. I have sent alot of e-mails to Horizon and get nothing. Not surprised and not going to quit them just feel let down by them. So any help you could provide would be appreciated. If you can't sorry for taking up your time and thanks for responding it in itself is appreciated.

What did you have macined ONE? The adapt. The muffler?
Normal use. What exactly is not normal about flying in a circle and landing. I don't race them I don't do aerobatics with them.
I use them normal. The deal is there have been more than a couple planes lost because of the adapter BEFORE the statement.
When i crashed I got in touch with Horizon and they sent me a cowl and another adapter. This one did have the statement in it.
And my second Sundowner had the flex pipe. My tube coming from it to fuel tank came off resulting in a second crash much
like my first (not as severe). I have not sent Horizon any e-mails nor complained about it. Don't know how it came off the
dealy is pretty long and tube was all the way down on it but did not have a retainer of any sort. MY FAULT.
The first time was not in anyway shape form or fashion anything I did wrong. It was not flown wrong, landed wrong, bumped or
bruised in anyway. The adapter broke at the head. Now they put a statement in with them but the guys that lost planes because
of the adapter before statement lost 1200.00 planes because of a faulty part sold by and recommended by HORIZON. That is
who I bought it from and even waited as it was backordered. So your saying you can recommend and sell faulty parts known to
break or found to break and not stand behind them.
I don't know what ANCILLARY means.
And i do know that taking off is rolling the dice but when the dice are loaded to begin with you don't really have a chance do you?
By the way if you still have your Sundowner manuel look at the pic and it shows the adapter and says nothing about a flex pipe anywhere (at least mine doesn't it is one of the first)
it don't even mention the adapter just shows it. What are you supposed to think when you see it and it says nothing, and when you get the
adapter you have been talking to Horizon about and they say nothing about not using the stock muffler and when you get the package all that
is in it is the adapter NO STATEMENT. You use it. It breaks. Plane dies downwind. Plane crashes. Simple enough.
That very morning I removed cowl and made sure all was tight, loktited, and everything in place as it should have been. I don't see anything I
could have done to prevent this from happening. And you know i even waited about 6 months before flying this plane to make sure I was experienced
enough to fly it. As you said LATEST EDITION HMMMMMMMMMM what about the other editions?
Looked it up and this part is needed to fly this plane as designed with the recommended engine setup as the wings are. Remember also that this Cowl was designed NOT to be cut using there recommended engines. And that was the biggest selling factor for myself was not having to cut up this beautifu Cowl on this beautiful plane.
Was that planes your talking about three flights and one did'nt make it off the ground. Heck mine did last 4 flights. Did the adapter cause this. If so did they all have the statement? If so and you tried it anyway I don't understand why you would do that. Had the statement been in the with the first adapt. I would surely have gotten the flex pipe as I did when the adapt. they sent DID have the statement. I am angry not stupid. Well depends on who's idea of stupid you use. Thanks for letting me rant, fellas nothing meant towards a single person here I know your all trying to help in your own way and I thank you. CHARLIE CROSS.

READ SAITO POST IT SAYS DO NOT USE THE STOCK MUFFLER WITH THE 90 DEGREE ELBOW. IT WILL BREAK. IT IS ONLY FOR THE FLEX PIPE NOTHING ELSE. THE ONLY THING YOU CAN USE IS THE ELBOW THAT COMES WITH THE MUFFLER. I TRIED IT AS HAVE A LOT OF OTHER PEOPLE AND WITH THE SAME RESULTS. BROKEN.
