Goupil Duck
The odd-looking Duck of 1916-17 was the result of further Curtiss attempts to invalidate the Wright patent. The design was originated and patented in 1883 by a Frenchman, Alexander Goupil, and showed surprisingly modern lines and features. While Goupil did not build his design because of lack of a suitable powerplant, he clearly recognized the need for three axes of mechanical control. Lateral control was by means of auxiliary surfaces that functioned exactly like latter-day ailerons.
Working from Goupil's patent drawings, Curtiss Project Engineer N. W. Dalton revised the design only enough to make it structurally sound and added a conventional undercarriage in place of Goupil's skids. The Duck was powered with a Curtiss OXX engine buried in the fuselage at the centre of gravity and drove a tractor propeller through an extension shaft. Built in Buffalo, the Duck was first tried at Hammondsport on the old Langley floats. Barely able to hop off the water with their weight, it was shipped to Newport News, fitted with wheel undercarriage, and flew successfully on 19 January, 1917.

P.Bowers - Curtiss Aircraft 1907-1947 /Putnam/
In 1916 Curtiss built this Duck from the 1883 design of Alexander Goupil in his continuing effort to invalidate the Wright patent. It was first flown as a seaplane al Hammondsport.

The Goupil Duck was transferred to the Curtiss facility at Newport News and continued its flights there as a landplane.

Goupil’s monoplane of 1884 was designed to duplicate the body of a bird as well as its wings. The novel feature was the inclusion - separately placed and not set in the wings - of elevons, the projecting control surfaces intended to act not only as elevators but as opposite-acting ailerons for control of roll. But they were not linked to the rudder action. Goupil’s steam engine intended as the power plant for this graceful machine was built but never installed in the airframe. But in 1917 Glenn Curtiss, who was trying to break the Wright patents on wing-warping - which the Wrights had said as early as 1908 included wing-tip ailerons - reconstructed the Goupil machine with a petrol engine and flew it. Between-wings ailerons in a biplane (most nearly corresponding to Goupil’s design for the monoplane) had been adopted by Curtiss much earlier.
