The Caproni Ca.1 was an experimental biplane built in Italy in 1910. It was the first aircraft to be designed and built by Gianni Caproni, although he had previously collaborated with Henri Coanda on sailplane designs. The Ca.1 was an unorthodox design, with an uncovered rectangular truss as a fuselage. Its two-bay wing cellule featured unstaggered mainplanes of equal span. Although the engine was mounted in the nose, it drove propellers mounted in front of the wings on long struts. The landing gear consisted of a dual mainwheel and skid arrangement, with outrigger wheels at each wingtip and a tailwheel.
The Ca.1 flew for the first time on 27 May 1910, but was destroyed in the attempt.
