MU-2 by D.P.Grigorovich

12k b/w drawing "History of aircraft construction in the USSR", Vol.1 p.402

Failure with MUR-1 forced designer to put more efforts on trainer flying boat project. For new aircraft D.P.Grigorovich took modern (at the time) M-11 engine. While general layout was unchanged, wooden hull was replaced by all-metal one.

Project started in 1926, assembly was finished in 1928. During construction aircraft was overweight by 150...200kg, mostly due to 10% oversize. Sluggish takeoff and poor overall performance resulted in rejection of the MU-2.
