DFW C.VI
DFW clearly wanted to follow the great success of their C.V with an improved design, and the C.VI was their next attempt. The C.VI used the slightly more powerful 220 hp Benz Bz.IVa for enhanced performance. To improve maneuverability, horn-balanced control surfaces were fitted which reduced the pilot's control forces to improve responsiveness, and the rudder and fin were enlarged.
Apparently the C.VI offered insufficient improvement over the successful C.V that was already in large-scale production and only a single prototype is thought to have been built and evaluated.
