The Curtiss Model 54 Tanager was an aircraft constructed in 1929 as Curtiss' entry in the Guggenheim Safe Aircraft Competition. It was a conventional biplane design with a highly streamlined fuselage similar in outline to the Curtiss Eagle, but of considerably smaller proportions. The wings were fitted with a variety of high-lift devices, including automatic leading-edge slots on the upper wing, flaps that extended the entire span of the upper wing, and "floating" ailerons on the lower wing that in the absence of pilot input, automatically adjusted themselves parallel to the airflow over the wing. The combination of these devices gave the Tanager a stall speed of just 31 mph (50 km/h) and allowed it to land in only 90 ft (27 m).[1]

Only the Tanager and the Handley Page Gugnunc passed the qualifying round of the competition, and ultimately, the Tanager was to beat its rival by only one point to claim the $100,000 (£20,000)[2] prize. The Gugnunc failing to get a minimum speed below 38 mph. Even before the competition was decided, however, Handley Page was suing Curtiss for the unlicenced use of the leading-edge slot. Curtiss claimed they were using the slots experimentally and would apply for a licence in any commercial use. Curtiss counter-sued Handley Page for infringements of six of their patents in the Handley Page machine.[3] They also cited a ruling that the British machine was not permitted to be imported into the US.

Following the competition, the Tanager was destroyed in a fire when sparks from its engine set the grass alight.[4]
