The Thaden T-1 was a high-wing strut-braced monoplane, constructed of corrugated aluminum, and powered by a 4250NaN0 Pratt & Whitney Wasp radial engine. It had a fixed conventional landing gear with a tailskid. Only one example was built (X3902); its first flight was on 15 January 1928, and its final flight ended in 1933 in a crash in Alaska. In 1986, the wrecked fuselage was recovered, and is now on display at the Hiller Aviation Museum in San Carlos, California.
