Has anyone fitted a DA50 with a cannister muffler? I would like to hear how well it runs, how it is to tune, what length header you used and mounting pictures if possible.

Thanks in advance.

Crig,
Excellent question. Are you talking about the in fuse mufflers like 3W sells? Someone at the field has one on a 3W24 and is sounds so nice, I though it was a four sroke for a second. I'd like to find out also. Here is a link to the 3Ws http://www.aircraftinternational.com...w_canister.htm

I don't know much, I had heard of the canister and was hoping someone had used one. I am really intrested to see the header and how it is shaped.

Hi Craig,
DA sells KS cans that will give you boost as well as quiet. They are a little lighter than the 3w cans, and give that extra boost. They also sells a header kit that you can custom make to fit your plane, as well as flex headers, and pre-bent headers. The 50 will be the same as a 100. It will require a 12" header legnth for the KS cans. You could go with a 50cc can or a 70cc can. You may want to talk with Dave about which one will fit your needs the best. I am using 2 70cc on my 100, but that may not be required on your particular setup. The pipes when setup per DA recomendations will give 2-300 rpm boost, and the engine will have good throttle manageablility, and transistion. Give Dave a call or send him an e-mail, they will get you fixed up with what you are looking for. The KS setup is very nice...it is quiet, gives a little boost, and transition is smooth. I have seen some surging, and blurbing with others, so I can't advise on those. I do know the KS systems work right on the DA engines.

Thanks for that information. I will speak to DA at toledo if I get a chance and ask them about the 70cc can vs. 50cc can.
As long as the power remains the same I am fine, I am mainly looking to have a quieter setup.

Who makes mounts that go around the cans to keep them from touching anything in the plane?

Thanks

What type of aircraft is this going in? I've seen lots of very good setups, but some are better tailored to certain airframes. Will this plane have an internal, or external (on the bottom of plane) pipe tunnel? I have some links to pics of different setups also. On my particular plane, I had custom made aluminum mounts made. i used thin gauge SS to hold the pipes to the mounts and used AeroTrend blue silicone (large) for dampening. There are lots of ways to mount these things. Actually if I had a pic of your plane where the pipe would be going I could give you much better info. . I like to think I'm pretty good with these pipes. It's one of the things I have studied up on for awhile. I've always liked that pipe sound and have run them from when I first started in GS aerobatics seriously. Even before I got into GS aerobatics myself, I built a few 30%'s, and 35%'s with pipes in them some time ago. You'll find that there is alot more things available, and alot of good websites on this. If you can give me a little more info. I can give you a more detailed answer. If you would like, PM me, and I'll send my e-mail to you so we can exchange larger images and things if nedd be. :-)

I ordered the KS Can and the flex header with my 50. I have not had a chance yet to run it. The can they sent me has 50/70 cc on the box and part # 86VS-4. Just curious if you find out this is not the best can for it would you let me know. In case your interested the can weighs 222gms and the header is 166gms.

I have never used Cans before and have only seen the installation photos on the Aero-works site. Do you have have a web site I could look at for alternatives?

Before you jump into buying a can setup -- make sure you know how much space AND overall operating length is required - Ask Desert Aircraft.
Then Don't try to use this setup shorter than recommended.
Most KS cans need a foot of header - never ledss - for typical operation.
IF you have less room and don't like to work on the airframe -- consider a non tuned can - these can be very effective.
Ask Desert Aircraft what they have.that is non tuned type.

As an alternative -- the JMB cans from RC Showcase work very well on headers only 6" long- the DA50 should perform nicely on these.
I have run KS tuned and JMB non tuned cans on their 100 engines ( same cyl -I believe) --and these setups work well.
The power gain with a non tuned can may be very small but the noise reduction is very noticable.
