The DP III was to be a commercial aircraft
for 8 people, a high-wing aircraft
with a wingspan of 18.40 m, similar to the Fokker F II. The empty weight
was planned at 1310 kg, the payload at 990 kg and the aircraft weight at 2300 (1924). A Rolls-Royce Falcon with 260 hp was planned for the engine. A speed of 160 km/h was expected and a price of 17,422 dollars was calculated. However, the fuselage turned out to be too heavy and the wings were therefore never built.
