This machine was the brainchild of a Frenchman, Henri Robart. Completed and tested at Amiens in December 1907, it apparently even supported itself in the air on December 21.
This machine has an upward curving main lower wing, an upper wing and 50hp Antoinette engine on the fuselage which drove two tractor props via chain transmission.
It was never heard of again.
