It was constructed by the brothers Armand and Henri Dufaux who had previously experimented with a model helicopter. This new aircraft incorporated a feature far ahead of its time; the concept of a tiltrotor. Based on what they had learned from their helicopter, the Dufaux brothers hoped to generate vertical as well as horizontal thrust from their engine installation, and conceived of an aircraft where the engine and propeller would be mounted at the centre of the airframe and would be able to pivot 180° to provide forward, upward, and even backward thrust (the latter to assist in braking). Experiments with a boxkite fitted with an engine in 1905 proved promising, so construction of a full-scale aircraft proceeded.
