Just a couple of plain old Thimble Dromes

Thanks Mark,  That's good to know.  I will make a note of it and stick it in the bag along with the engine. I normally replace all the gaskets but try to save the copper star reeds if they are in good shape.  This one was perfect in all regards.  I didn't go all out with it by polishing the tank etc. just left it as original as possible.  But I did trash the spring starter that came on it.  Nasty.

I'm always confused about the reeds.  In my rather moderate history with these I have always found the early star/copper reeds to work best.  I haven't had the best results with the various mylar and other reeds.

Must have been my Cox day.

A quick fix for the tank and actually prefered then the 'over-polished' look, is to lightly chuck the airtube of tank in a drill and lightly hit it with fine sandpaper and WD-40, this will take any surface oxidation off and recreate the factory machined look. This also works great on glowheads as you actually take very little material off the surface.

Here's the white replacement props, the OEM were the first versions Thimble-Drome made. Cox used to use Kaysun props, probably figured it was more profitable to make their own.

I have a couple of those white replacement props.

The Cox came with the items visible in picture 2 above, $15 as I recall. My plan as always is to clean it enough to run it then disassemble, clean again and bag it. I will probably replace the starter spring with a new one.

I will try your method of cleaning the tanks exterior. I tried this once before only using fine steel wool and a light oil. Even after a long A/F boil caked on castor remained in the valleys of the case. I don't like to use aggressive measures to clean those aluminum cases as they dull/scratch easily. Maybe some Hoppees #9 will help.

Hopefully I can scratch out an airplane for the other Cox keeping the vent/filler and needle extensions. I would think the previous owner had it in a model that incorporated a cowl.
