M-1, D.P.Grigorovich

After repairing of crashed 'Donnet-Levek' flying boat, D.P.Grigorovich built first flying boat of his own. It differed from the prototype by shorter fuselage of modified shape and wing airfoil similar to one used on Farman-16.

General performance was satisfactory, but it was obvious that there is a lot of room for improvements.

One built.
