The low-powered DP.VII was a simple, easily transportable, low-wing monoplane intended to make sports aviation more widely accessible.

Unusually, the one-piece wing structure passed through the deep fuselage above the lower longerons and could be extracted in a few minutes then transported away on a pair of trestles normally stowed inside the DP.VII.

At the time, the installation of the 22 kW (30 hp) air-cooled Haacke HFM-2 engine was seen as particularly clean, with only the upper cylinders projecting out of the cowling.

[1] The DP.VII's mainwheels were mounted on a single axle, conventionally rubber sprung to a cross member attached to the lower fuselage longerons by a V-form pair of struts on each side.

It had a similar fuselage and empennage to the DP.VII but a much more powerful engine, a Siemens-Halske Sh 4 five-cylinder radial producing about 41 kW (55 hp).
