07/31/2009. Remarks by Walter van Tilborg: "Development of the Merganser already started in the late 1960s, but a prototype did not fly until some ten years later. The aircraft was an original design of Peter D. Van Dine of Annapolis, Maryland and the first example was shown at the 1980 EAA Oshkosh Fly-In.

This first aircraft had a 100 hp Continental O-200-A engine, winglets and vertical fins were placed in the middle of the wings. It was configured as a flying boat and later received a 65 hp Revmaster VW2100D engine and the span of the canard wing was reduced. Only short hops were performed.

A second prototype was then built differing in many aspects, it was slightly larger overall and featured canted wing tip endplates. Engine was again a Revmaster VW2100D and during the initial trials this aircraft was also configured as a flying boat. Development of the Merganser was halted ca. 1983."
