  1. Step, I want to recite the rules: No need to pre-register in order to participate, just start your build in GB area, we will expel you if we don't like it I'm not sure about VK4502H as there is no evidence that it was ever completed but T28/95 certainly qualifies
  2. Original one-off was a race aircraft designed for the MacRobertson Air Race; use of Hamilton Standard variable-pitch propellers allowed for a 7 mph (11 km/h) gain; I say yes, it qualifies with proper adjustments and markings ('Warner Bros. Comet', NR257Y)
  3. I did not plan to build this model, I got the kit accidentally and all of a sudden found myself building it The plane was conceived as a fast light bomber and reconnaissance plane. To obtain high speed and good aerodynamics, it was powered by two M-103 inline engines in tandem in a fuselage nose, driving two contra-rotating coaxial three-blade propellers. The design had quite unusual look, with long fuselage nose and a crew cab moved rearwards, towards double tailfin. Wings had a fighter-like form and their span was rather short. The VVIA under Bolkhovitinov was enlarged to tackle the expected problems in the design of the Bolkhovitnov S. The rear engine was geared to two high-speed shafts which passed either side of the forward engine to drive the rear propeller gearbox, whilst the forward engine and gearbox drove the forward propeller via shaft through the middle of the rear propeller gearbox. The structure of the S was predominantly light alloy stressed skin, the wing having two spars with heavy flush-rivetted upper and lower skins, and the fuselage built up from pre-formed upper, lower, and side panels attached to four longerons to give a strong but relatively simple structure to build. A total of 29 electrical actuators drove the Fowler Flaps, undercarriage, (rotating 90deg to lie flat in the wing), exit flap of the large common radiator duct, and many other services. The tail unit consisted of twin fins with rudders attached to the tips of the tailplane, variable geared elevators and separate servo and trim tabs on elevators, and rudders. Detail design of the aircraft began in 1937 and construction in July 1938. The first prototype S-1 was built in 1939, but it was made in order to evaluate an airframe only and therefore was powered by only one engine M-103. It was unarmed and fitted with a fixed skid landing gear. It first flew on January 29, 1940, with B.N. Kudrin at the controls.[1] A maximum speed was 400 km/h. The second prototype S-2 was powered by two engines and was armed with a single machinegun and bombs.[1] Four 100 kg bombs were carried vertically in a bay between pilot and a rear gunner-navigator, under a common canopy. Its state testing started from March 20, 1940, and lasted until July 1940.[1] A maximum speed reached was 570 km/h (354 mph). The plane had good handling, except for take-off and landing, which were difficult due to high wing loading.[1] Its range and speed were also lower than estimated. As a result, it was decided to improve the plane further. However, the plane was not developed in a favour of next Bolkhovitinov designs.[1] It was first planned to build also an attack plane with 2 Ultra-ShKAS machineguns with a high rate of fire, in a rear part of fuselge, firing downwards and manned by a second crew member. Also an interceptor aircraft was proposed, armed with 37 mm recoilless rifle, firing upwards at an angle and manned by two crewmen.[1] The plane had no official designation given. It was mostly known as S - sparka (otherwise explained as spartak, skorost (speed) or Stalin), also known as BBS - blizhniy bombardovshchik skorostnoi (close-range fast bomber), BB - bombardovshchik Bolkhovitinova, LB-S - legkiy bombardovshchik sparka (light bomber paired), SSS - svyerkhskorostnoi samolet (very fast aircraft).[1] More about the prototype,
  4. Found another problem with the kit. The cylindric fuselage becomes a cone right before the engine #2 intake (blue arrow), there is a straight line instead of a curve (red arrows) I tried as I could to get it fixed before after Fairings
  5. I lost my status of unemployed that means that the build will slow down. Closed the body, decided that bomb bay will also be closed
  6. Nope - Valkyrie is waiting for this one to complete, I afraid there is not enough room in my shed to build both at the same time
  7. Yes, this thing was under state trial in 1936-1937 and was recommended for mass production. K.A.Kalinin died in 1938 that effectively ended the programme You are not alone, Ken
  8. Giorgio, - all the development machines qualify. In the "Concorde" example above the development fleet comprise of six aircrafts - yes, that's right
  9. Jack, is it a question or a statement? If it is a question what exactly do you want to know? BTW, "Petlitsa" (Петлица), plural "petlitsy" is written with "e" The bust us a great idea!
  10. I have no objections against "evaluation and testing" Phantom. As to Concordes - prototypes and pre-production machines qualify, six machines in total
  11. Intake reshaped Forming wing fairings
  12. I'm so glad this design had lost to XF-35!
  13. I haven"t read anything about 25% rule in the rules - welcome to the GB!
