'Ptenets' (Baby Bird) L-1 by N.R.Lobanov

73k b/w 'Ptenets' with N.R.Lobanov on controls,
"History of aircraft construction in the USSR", Vol.1 p.102

Scheme with front elevator of this trainer biplane was similar to Farman-IV but landing gear was completely different. Two separate legs with original shock absorbers (circle shaped, seen on the picture) provided safe wide track, while central safety frame protected pilot and engine in case of hard landing.

Major elements of aircraft structure (including safety frame) were steel tubes, soldered with copper. The rest - bamboo and pine. Wind skin was on the upper side only. Control stick was hanging from the upper wing leading edge.

Aircraft was presented on the Second International Airshow (Moscow, 1912) and won The Big Silver medal. About hundred flights were performed on the L-1.
