fjaweijfopi4j48 Posted December 14, 2018 Share Posted December 14, 2018 A build from 9 years ago: The use of radial engines in small airframes tends to create very cartoon-like shapes of an undeniable appeal. Some of these stumpy, chubby, cute little bugs are well known (like the Gee-Bee racers or the Polikarpov I-15) while others are more obscure subjects. If this type of design was a monoplane (like the Bristol Type 72 Racer or the Polikarpov I-16), then the effect was even more notorious; but if on top of that we have a “flying wing” example, then the resulting aesthetics are just as fun as they are attractive. The BOK-5 was a Russian design proposal originated –as the designation states- at the Bureau of Experimental Aircraft (Buro Osovikh Konstruktsii) and the project was led by V. A. Chizhevsky. It had a Mikulin M-11 as its power plant and a span of less than 10 meters. It had metal structure and the flying surfaces were mostly fabric-covered. After initial flights and some adjustments the plane revealed itself as a very good machine, but notwithstanding its virtues didn’t go into production. The Scupley-made fuselage master fitted comfortably in the Mattel Vac-U-Form plate and promptly I had my two fuselage half-shells. The interior was furnished according to references and then the wing was fabricated out of styrene sheet and rod as per photos. A sort of Townend ring was created laminating styrene sheet on a metal tube–see also the images to follow the simple procedure- and an “Engine ‘n Things” Mikulin was retrieved from deep hibernation in the spares bin. This particular engine is not the best one I have seen from this manufacturer, being the back side well detailed and the front side marred by the area of the cylinders enclosed by the pushrods, which was a pool of resin. Some pinholes –or potholes- further enhanced the overall results. Wing and fuselage were mated, but no eggs were laid. Details on the fuselage were added and then the under-hanging control surfaces for the wing. Wheels came from Aeroclub and landing gear structure was a combination of assorted bits. Last details were the home-made wooden prop and a number (14) of photoetched control horns, which amused my ears with the “ping” sound they made every time they jumped to hyperspace from the tweezers. Finishing presented a dilemma. The original color was apparently either white or light grey, but I think that aluminum is a possibility as well. Some color reported as red –which will make sense being this a Russian plane- was applied to the nose ring, leading edges and to some trim lines on the upper fuselage. But for the annual parade a very original and psychedelic scheme was applied, a la Kalinin K-12 “Zhar Ptitsa”. This artistic scheme is represented in different ways by several sources. The usual heavily retouched Russian photos duplicated with hectographic gelatin in the cold basement of a Buro (http://en.wikipedia.org/wiki/Hectograph) did not help. That made me lean towards the original scheme. Few decals for this one: only the concentric circles for the wheels and the BOK triangular logo for the rudder 24 Link to comment Share on other sites More sharing options...

Courageous Posted December 15, 2018 Share Posted December 15, 2018 Nice looking subject Moa. Can I take it that you achieved the wing ribbing by 'scoring' the insides of the wing? Stuart 1 Link to comment Share on other sites More sharing options...
