RE: Cox 049 mufflers
Adrian,
We had them quoted a couple of times (OEM Cox version)and pricing was too high for the low run we were after (1,000).
We are presently having them quoted by another engine manufacturer and, if pricing pans out, will manufacuture them before the end of the year.
Our target is to have a retail price not exceeding $14.95.

RE: Cox 049 mufflers
There was someone for awhile that made a silcone rubber muffler that was surprisingly quiet. Not the normal metal idea but who is to say that metal is the best material for this?

RE: Cox 049 mufflers
I think that was someone on the forum here who made a muffler out of blue rubber connector from a .60 size 'piped' engine... and used steel washers top and bottom... and a drilled hole in the rubber for a 'spout' of brass tubing for the outlet. Search for 'cox muffler' or just for 'muffler'.

RE: Cox 049 mufflers
I'd like to see the kind like the TD R/C came with (same basic style as the one used on the Queen Bee). Easier to have provision for muffler pressure. Speaking of R/C, I plan to soon place an order for one or two of those nifty R/C reedies y'all got. Still not the ideal R/C carb solution, but cost effective, no doubt.

RE: Cox 049 mufflers
Bernie, MECOA has these Tatone mufflers for the Cox engines. They have less power loss than the OEM ones. Mabe you can cut a deal with them and stock these for the time being until the OEM ones get manufactured.

Yuu:
My experimental throttle, would work as a muffler/exhaust diverter as well.

RE: Cox 049 mufflers
That's pretty neat, Dave, congratulations.
In general, the throttle rings work pretty good and they sell well for us.
However, the greatest drawback with them is that they preclude the simultaneous operation of a muffler. Because of this, we developped this product:

Not quite the holy grail but a decent compromise.
I do like your setup and it seems fairly easy for a modeller to make himeself.
Cheers

I have made several mufflers like this. They work great and as for a throttle this throttle also works great if you do a good job as you build it.

Any update on the muffler production?
Many Thanks,

You are correct. I have one around somewhere. You stretch the thing over the head and down onto the exhaust. Darned if I can remember who made it. Mine is gray silicone, relatively thin walled.

Adrian,
There was lot of back and forth with correpondance, drawings and samples but we finally obtained a reasonable quote the other day. We will be placing the order shortly and they should be available for sale by March or so.

RE: Cox 049 mufflers
Hhhmmmmm... A thin silicone rubber 'sleeve' for a muffler, that you pull down over the head and cover the exhaust. Now, if we used a 'birth control' device, and left it full size, and wired the thing shut on the bottom of the cylinder, and let it hang back under the plane, or inside, it would collect all the exhaust 'slop' and keep the plane clean too. Now, what could we call it?

RE: Cox 049 mufflers
Adrian,
Our manufacturer is ready to go but we have not given the go-ahead yet due to financial constraints. We have so many projects on the go and they all cost big $$'s.
We recently made 020 glow heads, killer Bee cranks, 049 TD venturis, 020 RD venturis, 5-Fin glow heads, 049 TD cylinders, etc, etc.
Still a project, however
