This Build thread will tackle the Russian Fighter Escort Moskalev SAM-7 "Sigma" in the great effort for Russia to design effective Tailless Craft for the promise of greater maneuverability, speed, fuel efficiency and larger threat zone in combat.
The project is spurred on by the FliteTest Forum Challenge for WWII Concept planes
I choose the SAM-7 because it looks like a fighter version of the Kalinin K-12 (Build Thread here) which I am also taking on. I found the SAM-7 as a familiar styled silhouette on the bottom of the Kalinin K-7 model Kit page. dug around and found the link above. There isn't a whole lot more to say on this yet but stay tuned.
Here are some Concept Drawings:
And a lego version:
History (lifted from HERE)
A.S.Moskalev was an outstanding Soviet aircraft designer who created a lot of unconventional projects, many of which were built and successfully flew. The SAM-7 was an extraordinary tailless all-metal aircraft featuring the delta wing with two fins on its edges and a short fuselage with the separate pilot and gunner cockpits. The plane was powered with the M-34 engine (750 hp) cooled by the vapouring radiator in flight. The retractable conventional radiator housed behind the pilot's cockpit was used on low speeds and on take-off. The wooden propeller had four blades. Airplane's armament consisted of four 7.62mm ShKAS machine guns : two above the engine and two flexible - in the gunner's cockpit. The SAM-7 was built in 1934-1935 and was initially tested on the aircraft plant airfield. Despite good characteristics the whole program was cancelled by the VVS in favour of the same delta wing tailless bomber K-12 which entered small series production on the same plant a year later.
