Use in Radio Controlled Models
At the time Cox developed the first Cox engines, they were used in Control line and Free flight model planes as there was no market for throttled Radio Control engines back then. Radio Control, although first developed in the 1890s it was not available for model airplanes until the 1950s and did not become economically viable for small model planes until the mid-1970s and even then was for the modelers who could afford it. It was certainly out of reach of the hands of most children.
From the mid-1960s Cox produced throttle control devices for some of their engines, however these were not as effective as throttles on other brand engines as the Cox throttle worked by restricting exhaust flow. Exhaust throttles were produced for most Bee and all Medallion engines but not Tee Dee.
It wasn't until 1988 that Cox produced an engine with a true R/C carburetor and that engine was the Queen Bee .074. Then in 1994 Cox finally produced the Tee Dee .05 and .09 which both had a conventional R/C carburetor, with adjustable airbleed, and a full muffler.
In 2010, an after market R/C throttle/choke has been developed for the .049 reed valve engines. This throttle is attached to the choke tube on Sure Start .049 engines and can also be adapted to fit .049 reed valve engines with an integral tank. The throttle was developed by Saras Associates and is being marketed through Cox International.

Famous quotes containing the words radio, controlled and/or models:
“Denouement to denouement, he took a personal pride in the
certain, certain way he lived his own, private life,
but nevertheless, they shut off his gas; nevertheless,
the bank foreclosed; nevertheless, the landlord called;
nevertheless, the radio broke,
And twelve o’clock arrived just once too often,”
—Kenneth Fearing (1902–1961)
“Our eldest boy, Bob, has been away from us nearly a year at school, and will enter Harvard University this month. He promises very well, considering we never controlled him much.”
—Abraham Lincoln (1809–1865)
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
