I will happily admit that I have a fascination with aircraft that have spatted landing gear, I also like ungainly and unusual looking aircraft. So far I have constrained myself to single engine aircraft but the field of the ugly and ungainly gets ever larger when you add extra engines.The worst part is that there are kits in 1/72 scale of some of these flying abominations. Witness this; the Handley-Page Heyford, a multi-engined bomber that was the mainstay of the British bombing force in the mid-late 1930's. The last of these were only retired from front line service in 1939!
But, to find true madness, you have to travel to the insanity that was the Soviet Union. If you are nutty enough to think that Karl Marx understood anything about economics or human nature you have surely no faith at all in the laws of aerodynamics. Many people (OK, a few oddballs) have heard of Andrey N. Tupolev and his fetish for really, REALLY large aircraft, so you won't be surprised by the ANT-20.
But to fully embrace the utter lunacy that was Soviet aircraft design you have to become familiar with the work of Konstantin Kalinin. He was a man that fully understood the brute-force Soviet mindset as well as being an out-of-the-box engineer. After two unattractive, but entirely conventional, airplanes the KA-4 and KA-5 Kalinin let his ambitions run loose and designed the KA-7. This apartment-block sized thing looked more like a avant-garde bit of sculpture than an aircraft that was expected to actually fly. As a civilian airliner it was expected to house 120 passenger seated inside the immensely thick wing. As a troop transport 112 fully-equipped soldiers were to ride in it and as a bomber it could hoist 21,000 pounds of bombs. In the military role it was to be armed with eight (count 'em, eight) 20mm cannon and eight machine guns. Now I understand where H.G. Wells got his some of his ideas for "The Shape Of Things To Come". No Deviant-Art Deisel-Punk dream comes close to the reality of this object.
Behold the Kalinin KA-7 in all it's glory!
NOW FOR THE WORST PART!
There are models of all of these aircraft in 1/72 scale! I currently have two (don't ask why) of the Matchbox 1/72 scale Heyfords.
And a company called Mirko Mir makes both the K-7 (for a paltry $299US)
and the K-12 (at a much more reasonable $39.88)
I am a man sorely tempted!
