These are all old builds, and in retrospect should have been posted at the beginning of these series. They often represent the first, hesitant steps on scratchbuilding. Here is another from 2008, 11 years ago (original text as posted then): The Coanda Jet Riding the Flames, The dawn of the jet era…in 1910! Romanian Henry Coanda of later “Coanda effect” fame found himself taking off the ground –involuntarily, I am afraid- during a ground test of his revolutionary creation. Given his reduced talents to keep the aircraft aloft, the flight was very short and ended in disaster –although he escaped unscathed- , but a careful observation of a strange phenomena –the flames exiting the combustion chamber adhering firmly along the sides of the fuselage- later became one of the most important contributions from Henri Coanda to physics, specifically to the dynamic of fluids, known as the Coanda effect, The mysterious engine was in concept similar to the one utilized, decades later, in the Caproni-Campini CC-2, that is, a “mixed” engine, with an internal combustion unit driving the compressor stage of the jet. His design, that incorporated a great deal of innovative features, went, for no reason, ignored by mainstream aviation history until recently. The elegant and futuristic lines of his design were hard to resist, so out again with the glue, styrene, filler, sanding stick and the metal bits. Available plans differ from each other and all of them differ from photos, so there you are submerged in the relentless fogs of scratch-building. Hopefully the images will give an idea of the materials and techniques involved in this attempt, but perhaps most important, will render a general sense of the gleaming beauty of the design. Seemingly flying away from a still of Fritz Lang’s “Metropolis” –by the way, a much later production- its proud pilot could well have been Little Nemo in Slumberland. Some of us are interested in aviation history, some others in the constructional aspects of modeling, and some just love these planes for their diverse, rich, alternative, disconcerting but immensely attractive aesthetics. Whichever the reasons that lead you here, I am sure you will like this first jet of aviation history.
It has been in the works long enough. Resin, vacu canopy and decals from Miniwing. Cannon fairings courtesy of Master. Brass by Shelf Oddity, which means it is the test article for the brass parts - an awkward way to promote our product and equally awkward way to excuse imperfections. First two photos with my trusty companion, who did the part chopping: and lent a helping brush: Now, the Attacker himself: "We there yet?" For anyone still awake - few WIP photos, focusing on metal bits, because resin parts came together without any fuss: The one showing dorsal bleed doors and boundary layer vents: The one showing boundary layer ramp inside intake (that no one will ever notice): The one showing ventral boundary layer vents along gear struts locks in u/c bays. And the one showing tremendous effort on my part - making a cut through the middle of the tail wheel to make it a twin tail wheel.
On a rare occasion I do finish a model. This time it came out like that: (some last adjustments:) and here we go: Ok, enough. Off to the scrapyard Full story can be found here http://www.kampfgruppe144.com/phpbb3/viewtopic.php?f=3&t=3271. Short story: Panel lines (Matchbox-style) were removed, some brass bits from upcoming Shelf Oddity set added. And then there was miserable process of filling and sanding and filling and sanding and filling and sanding and filling and sanding and... which seemed to have no end. But finally I got to dust off my airbrush. Metal parts are AK Xtreme Metal (easy and foolproof). Kit decals turned out to be excellent (save for NACA tail band), panel lines were reinstated using pencil and shaky hand and this is it.
My next entry for the group build is the 1/72 Yak-15 from Amodel, bought at the list price from Hannants (6.50 pounds): The instructions (not shown) proudly proclaim it to be the first Soviet aircraft with a turbojet. On to the sprues and decals: This will be the third Amodel kit I've built, and hopefully the third I finish. This is a warm-up for the Yak-28PP I have in the stash, and I also want to build a Yak-1 (Amodel) to examine the family resemblance. There are two schemes: one overall red, and one green-over-blue, which is the scheme I plan to do. As the photos show (or not!), there's a fair amount of cleaning, sanding and what I call therapeutic fettling to be done. My Scandinavian Spitfires will have to wait...
