Propeller Displaycard
A Thimble Drome dealer display card showing propellers from a tiny 4"-2 up to a mighty 9"-4.  The 3-blade props are for the Flying Tiger P-40 and the Super Sabre F-100 models (1958).

And then there were those propellers!  Of course made from solid Nylon - not only tough enough to withstand your search for the holy grail of a perfect landing, but even DUBL-TUF...

Today, most people stay away from "EXTRA Flexibility" propellers, but would still be interested in buying a nice propeller for 20 cents.

A more usual propeller package as you would have bought it in your local hobby shop around 1960. Price raised to a whopping 25 cents per prop.

Each year, new models were added to the range of Cox powered models.
Often the same model re-appeared in a new outfit or in a different color scheme.



The "Bendix Trophy Racer" came ready to fly in an eye catching Avion Flight Set box (1964).

The early Cox catalogues presented the models in such great artists impressions.

Thimble Drome Paper Bag

This spare part paper bag shows the Thimble Drome (TD) logo and mentions the TEM-TROL temperature control system used for the manufacturing process. Due to constant temperatures and high coolant flow rates, it was possible to achieve excellent precision and high quality standards, long before the era of CNC machines.

I want to note that most of the contents of these web pages became possible due to communication via the internet, because of nice people who answered my stupid questions. Especially helpful has been the extremely thorough historical research by Dan Sitter, published in the Engine Collectors Journal (ECJ). Additional important information came from Ken Croft, Bob Gardner, Paul Gibeault, Peter Tarn, Larry Renger, Joe Wagner, Max Zuijdendorp, and many others.

Thank you all for sharing small bits and large chunks of information!
