ROM-2, ROM-2bis, MDR-1, by D.P.Grigorovich (OMOS)

12k drawing from "History of aircraft construction in the USSR", Vol.1 p.401

Long range maritime reconnaissater, sesquiplane flying boat derived from unsuccessful ROM-1. The wing and the hull were radically redesigned, most of the plywood wing skin was replaced by fabric. Tandem engine installation replaced by two separate nacelles with more powerful engines. As a result payload (including fuel) almost doubled, other parameters were improved.

Trials took place during Summer 1929. Performance was better than that of ROM-1, but still unsatisfactory for 30's. Test flights ended when aircraft was damaged as a result of rough landing.

It was restored with some changes. The hull was shortened by 0.2m, engines were raised above the wing on short N-struts. Aircraft was redesignated ROM-2bis. But it was obvious that this scheme has no future and improvements made are more cosmetic than for real. ROM-2bis was not flown.
