LANZIUS L II USA
The L II was derived from the tandem two-seat L I developed by the Lanzius Aircraft Company of New York in 1917 under US Army Signal Corps contract (and referred to by the manufacturer as the "Lanzius Variable Speed Aeroplane”). The L II single-seat fighting scout of circa 1919 was novel in featuring wings possessing both variable camber and variable incidence. A two-bay equi-span biplane powered by a 350 hp Packard 1A-1237 six-cylinder vertical inline water-cooled engine, the L II utilised a system of cables and pulleys to change camber and incidence, the latter varying from 0 deg to 15 deg. Flight testing is believed to have been conducted at McCook Field, only one prototype being completed.

The Lanzius 'Speed Scout' appears to be misnamed; the external truss on which its adjustable wings were mounted created a great deal of drag and made it anything but fast despite use of a 400 hp Liberty V-12 engine. The wing incidence could be varied in flight. Perhaps unsurprisingly, the fragile aircraft crashed fatally on its first flight as a result of wing failure. -
