• "The orthoptère of Spiridon Tsapenko (Спиридон Цапенко) and Joseph Michel Ambroise Farcot. The two pictures taken by Branger on July 21, 1908 show a small scale trial version. This scale version had a 12 hp Farcot engine of 20 kg weight, bringing the total weight of the machine to 150 kg. The inventors intended to build an even lighter orthoptère, but if that intention materialized needs more research."
