Aft of these rooms and immediately beneath the wing was a total of eight fuel tanks, which had sufficient capacity to permit flights of around 2,000 km (1,243 miles); the fuel tank could be resized or even located elsewhere in the hull at the customer's preference. Behind the fuel tanks were the sizable baggage compartment,

A variety of powerplants could be fitted to suit customer preferences. The Do R could typically carry 21 passengers in two

During assembly, the wings were the final element to be attached. Somewhat unusually, the framework of the hull was assembled upside

It was claimed that virtually any pair of engines in the 1,400-2,000 hp range could be installed and that this choice was dependent upon customer preferences. Furthermore, it was stated that the location of the engines above the middle of the wing in no way limited the flying boat to using only two

diameters. In the event of a single engine outage, when operated in a twin engine arrangement, it was stated that the flying boat could maintain stable flight on only the one remaining engine while carrying at least two-thirds of full payload. Mid-flight repairs to the engines could be performed,
