The Ca.6 was a single-engine propeller-driven biplane with a traditional configuration with wings in the bow and tail fletching, but it had no fuselage : it was replaced by a light structure formed by two beams of unshelled wood and some vertical reinforcing uprights that supported the planes of tail.

The wings resumed the double curvature profile that had also characterized Caproni aircraft immediately preceding, but with not very lucky results: the aerodynamic characteristics of this type of profile, which had been suggested to Caproni by his friend and colleague Henri Coandă, proved to be once again unsatisfactory.

After the vicissitudes linked to the Second World War and the reopening of the museum in Vizzola Ticino, the Ca.6 was again exposed to the public.

He found his definitive position in the Museo dell'Aeronautica Gianni Caproni, reopened in Trento, in the nineties.

At the time of its transfer to Trento, the Ca.6 has undergone a new intervention; however, due to the lack of availability of reliable technical drawings and other necessary historical documentation, a real restoration did not take place, but only a conservation procedure.
