The Roze, Perret, et Chaffal biplane was a large overhung biplane that might have been designed by Francois Denhaut and was made partly of steel tubing. It had a single trapezoidal tailplane aft only and no apparent vertical surfaces. The arrangement of the two pusher propellers was similar to that on the Wright. It was damaged in 1909 at Poitiers, and probably rebuilt into the photographed configuration, which was tested at Poitiers, France, in May 1910.
