The Russian navy in WWI made great use of flying boats, and the Grigorovich M-9
was its most common plane. It was able to land reliably on seas, lakes, and even snow. Over 500 were built starting in early 1916, making it one of the highest-produced Russian planes in the entire war. While it was a three-seater, it was frequently flown with only a pilot and a gunner. The M-9 was used both on the Baltic and the Black Sea, and it as armed with a variety of weapons, from Lewis guns to Oerlikon cannons. This model shows a version with a Vickers machine gun.
This product comes in both 1:144 and 1:285/6mm/1:288 scales. The smaller scale model uses a propeller disk rather than propeller blades, since the latter are hard to print at small scales. The disk can be snapped off if you prefer.
