of monoplane by Tereschenko and Pishof,
with more powerful engine - one was built with 60hp Gnome and two with
80hp Gnome engines.
Flight tested by military pilots in combat conditions in
1914-1915. Pilots noticed good
flight performance, but poor pilot's sight did not allow to use aircraft for reconnaissance purposes.
Tereschenko-6 was almost identical to Tereschenko-5bis, but was powered by 60hp
Rhone engine. Performance was good.
