For Sale Three (only one left) Cox .020 silencers for sale.

I have for sale "three" Cox .020 silencers with gasket/shims.
They are designed similar to the Cox car silencer where the cylinder screws down onto the silencer and tightens down on the crankcase.

Installation instructions

Please check the cylinder dimensions:

The late model Tee Dee.020 and PeeWee.020. cylinder dimensions.
The dimensions and shape of the bottom of the cylinder is .418 inch dia. (aprox. 10.62~10.63mm)

The early Pee Wee cylinder dimension is .438 inch dia. (aprox. 11.11mm)

The parts that interfere (i.D.) with the engine cylinder will need to be shaped. (enlarged?)
Using a slightly undersized wooden dowel and some 220-grit sandpaper wrapped around the dowel to carefully enlarger the hole for the cylinder sleeve. Don't overdo it now! you want a snug /slip fit.

I have included a drawing of the different dimensions of the Cox 020 sleeves.

Included with the silencer are two different thickness size shims (.005 / .008) (0.13mm/ 0.20mm) to give the silencer a tight enough fit when the cylinder is tightened down and the silencer is snug enough to not move. If it does, you'll need to add one of the shims to the bottom of the silencer.

One more FYI (if necessary)-- use a small amount of Permatex (non-hardening) gasket sealant on the upper and lower faces of the silencer to get a really good seal.

The exhaust tubing is 5mm I.D. diameter.


If you are still interested in one of them let me know.

The cost with shipping is $44.15 using Friend & Family through PayPal.
If you use Merchandise, then the cost is $46.14 (PayPal's 4.5% Fee)


Private email me (message) if interested
I'm posting it here first before posting on the R/C Group Classifieds.
What every doesn't sell I'll be posting it there afterwards.

Thanks,

Do you have a vid running the silencer or RC carbs?

Sorry I do not.
I'm not much of a tech guy.
No smart phone, and not on any of the media stuff ("X", twitter, Facebook etc.)
No GoPro either.
I still use a paper map to find and get directions.
I only have a computer because of medical stuff (appointments, results, and things you no longer can do "in person"),
My pension and Medicare and doing Federal taxes ( which I need to start on?  --Turbo Tax --)
