I am not sure this is the place to ask but does someone know a good source for a OS .15 pitts style muffler ?

I picked up a Bisson Muffler two days ago from a local hobby store http://www.hobbyhobby.com/ the cost was $29 I'm using it on my OS 15 in my L-19 Bird dog.

if going to have to use a pitts type muffler i would suggest moving up in the cubic inch depart ment. like a thunder tiger .18 an old OS fp .20 because adding a pitts muffler to a .15 will be like adding a small .10 to the plane or less.

Here's an alternative that might do the job:

But I'm puzzled by the comment above -- I've never heard that pitts mufflers reduce power, and I don't see any reason why they should.

take a measurement to see for your self.

I hope it's not a huge loss of power[] my L-19 called for a 15-20, i went for the OS 15LA and will use the pitt muffler to save cutting up my cowl. I'll post my thoughts after the maiden flight.

Thanks, rywil

run it on a test stand. just use a small piece of wood and cut it out with jig saw. this will also help with break in if any is required on your motoe. after broken in get a reading with the stock muffler with baffle removed then run it with the pitts muffler and lets us know the results. i bet you lose about 500-1000 rpm with the pitts.

Looking to get two Pitts mufflers for my Magnum XLS 15A engines for my Nitromodel P-38.

Geezzz ... where did I see that photo from Joe Wagner, where he made a muffler out of WOOD and attached it to an engine, and it worked? Oil soaked, but it was working...
