I will let someone else post the next challenge. Does a forum member have a WWI Aero magazine P3V ( photo to three view software program) and know how to use it? It would be great to see drawings of these flying machines.

On this side view can be seen that the two propellers are placed close together so that they overlap. It is remarkable that
Max Bourcart patented such a construction on
September 9, 1902 in German. [German Patent
145547 - Flugmaschine mit zwei Luftschrauben, deren Flügel ineinandergreifen].
By the way Lange (Typenhandbuch der deutschen Luftfahrttechnik) gives the first flight of this machine as March 1910. Pilot was the designer Bourcart himself
About the P3V program, I think that development was stopped years ago. It will not work in todays operating systems (Windows, Mac etc.).
I will seek out the pictures of the machine in Cross and Cockade US.
