The Adcox Aviation Trade School was established in Portland, Oregon in the 1910s. Aircraft created there as student projects starting in the late 1920s include the Adcox 1-A, Adcox Special, Adcox Student Prince, and Adcox Cloud Buster.

The Adcox school began as a trade school for automobile and gas-engine mechanics, but in 1920 it added a course in aviation to its curriculum, focussed on the construction and repair of airplane motors.[1]

At different points in its history, the organisation was known as the Adcox Auto and Aviation School, the Adcox School of Aviation,[2] Aircraft Builders Corp and the First National Flying System.

In late 1929, after a new two-story building was opened, the school had the largest enrollment of any aviation school in the Pacific Northwest, with 100 full-time students.[3]
