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.

Loaded weight, 1,200 lb (544 kg).
Span, 38 ft 0 in (11,58 m).
Length, 25 ft 0 in (7,62 m).

There are at least two other machines known as designed and built by Lanzius. The second one with the spurious (not contemporary) designation L II is the one shown by Dave.
  The second machine (february 1918) was flight tested at Langley Field, Virginia. A Sturtevant 8-cylinder engine was fitted. The machine looked like a quite normal single seat fighter other than the exposed variable incidence wings
  The third machine was referred to by Lanzius as "Speed Scout". The Signal Corps ordered 4 of these machines serials 40034-40037. Power was by a 12 cylinder Liberty engine of 400 hp. Machine 40034 crashed when loosing its wings in flight on 29 June 1918 killing the test pilot Lester Holt. On the picture we see the Speed Scout with serial 40034 before the crash with the unlucky pilot. The other three machines were built but were stored at McCook Field never to fly.
