JOCKNEY Posted December 21, 2020 Share Posted December 21, 2020 The secret to the successful completion of any Blitzbuild is preparation, simplicity of kit assembly, and attention to detail. So it was only natural that Unicraft immediately came to mind. Picture below, along with the history of an aircraft I doubt many of you will have heard of, Info below from Unicraft History In early 1943 when not only there were no captured examples of jet engines and aircraft, but even there was no information at all about German and British turbojet-powered aircraft in the Soviet Union, the designer M.I.Goudkov has completed a prototype design study of the Gu-VRD turbojet-powered fighter. The project documentation was submitted on March 10, 1943. The Gu-VRD project was reviewed at NII VVS (Scientific Research Institute of the Air Force). A resolution of the leadership of the institute dated April 10, 1943 ordered: "Prepare urgently an evaluation review of the superfast fighter-interceptor of M.I.Goudkov design powered by Lyulka engine". Department chief I.I.Safronov wrote in his memo of 17 April 1943: "... Apparently, the aircraft would fly with the claimed speed, but the problem is that as of today there is no engine, just the name of its designer. Hence, the emphasis is to be on the engine". Gu-VRD was a monoplane with the engine placed in the bottom of the fuselage aft of the nose section. The side view of the aircraft had a step behind the engine's nozzle after which the fuselage had a much lesser cross section. Later this layout was named "stepped" and was used in the first Russian jet fighters MiG-9, Yak-15, La-150 and others. Some sources claimed that the stepped layout originated from German design studies of 1944- 1945. It is evident now that the stepped layout appeared in the USSR in 1943 without any foreign influence. The tipped nose of the aircraft had four segmented air intakes. The wing had trapezoid plane with curved tips. The horizontal and vertical tail design was standard. The retractable landing gear had two main legs and a small tail wheel. In the meantime Goudkov in his explanatory memo to the project wrote that by that time a combustion chamber of Lyulka engine had been tested, a two-stage axial compressor had been built and tested, achieving 1.25 compression ratio in each stage with 0.75 energy efficiency ratio, both figures rendered quite successful. An engine prototype rated at 750kg of static thrust had been designed and built to 70% readiness. Goudkov noted that the engine itself and majority of Lyulka design team were in Moscow. Lyulka planned to begin developing an engine rated at 1,500kg thrust. The engine had 700kg weight, 0.9m diameter and 2.1m length. Due to the Lyulka engine release delays the Gu-VRD was never completed, staying however one of the world's first JET FIGHTER projects. ________________________________ Technical data Crew 1 Engines 1500kg Lyulka...? turbojet Wing Area 11m2 Max.Weight 2,250kg Speed (sea level) 870km/h (calculated) Speed (6000 m) 900-1000km/h (calculated) Climb to 5000m 1.39min Range 700km Endurance 1h Landing Speed 141km/h Take-off Run 222 m, later considered to be too optimistic Armament 1x20mm ShVAK cannon 200rpg 1x12.7mm BS gun 200rpg -------------------------------------------------------------------------------- Based on "Samolyotostroyenie v SSSR (1917- 1945)" [Aircraft Development in the USSR], Vol 2, published by TsAGI in 1994.

You really keep the best for yourself! Silly question: when did you go through such an existentialist crisis that Unicraft kits became a must-buy? I shall be watching!!! Have fun.

JR There were a number of options to repent for past indiscretions 1. Self flagellation, too much effort and I don't have the stamina. 👎 2. Act of confession, that's soul bearing stuff and if I have to go over all the misdemeanors, I'll miss Christmas altogether. 👎 3. Purchase something unique from Unicraft, repent, swear continuously throughout the build👍 The fit (I mean this in the broadest sense) of parts is so bad, I'm going to have to post a health warning before I show any pictures ! It's even got a vacform canopy so that's got the potential for disaster as well ! Happy days 🥳 2 6 Link to comment Share on other sites More sharing options...
Graham Boak Posted December 22, 2020 Share Posted December 22, 2020 I can honestly say that the parts look far superior to the example I have of their MiG.7, which had short-moulding and resin intrusions (large blobs on the surface and making the shape difficult to make out. It had airholes pretty well everywhere and mold lines. After considerable (if sporadic, for obvious reasons!) cutting, filing, filling and smoothing sessions I have reached a stage where it looks only somewhat inferior to yours. Fit? Don't make me cry... Some kits are meant to try our dedication to the cause of modelling. 1 1 Link to comment Share on other sites More sharing options...

Angus Tura Posted December 22, 2020 Share Posted December 22, 2020 Pat. You mad impetuous fool... I have finished one unicraft model, their MiG Skat. I did it with its wheels up and would strongly recommend that. It solves many of the laughable flaws of unicraft kits at a stroke. Paint the cockpit; assemble; cover everything, especially wheel wells with epoxy putty; put in a warm place. Then, carve and sand approximate desired shape out of blob of resin and putty; paint; stick on transparency; insert stick underneath; enjoy approbation of fellow blitz(en)ers. The MiG Skat took me about six months...so, I don't see how you can possibly go wrong. Alan 4 Link to comment Share on other sites More sharing options...

JOCKNEY Posted December 26, 2020 Author Share Posted December 26, 2020 Ok, First of all, the Jockney household is not a happy place as the induction hob has packed up on the cooker (Fault E2 ?) so we still haven't had Christmas dinner ! However, I managed to sneak away for a bit of covert modelling during the wailing and nashing of teeth ! Going to start with both fuselage halves needs a floor and an instrument panel to be scratch built, so need to find materials. This Heller Simoun sprue can be recycled to make the floor and instrument panel So the tactic is to paint stuff, and allow the no building time for stuff to dry, so some parts painted, need to look for undercarriage legs as the kit ones are useless, a control column and do some research on paint colours. Sorry about the above photo it was 15:03 cheers Pat 5 Link to comment Share on other sites More sharing options...
JOCKNEY Posted December 27, 2020 Author Share Posted December 27, 2020 Session restart Cockpit assembled Argument with a clamp, yes the resin is very brittle ! Wings on , MIND THE GAP ! No I didn't break that bit of the wing off, it wasn't in the box.... Still, can't get any worse can it ? This is the tail, which appears to have a piece missing so needs the fuselage extending... So drill out the tail, use a splint on the inside, electric cable with the insulation left on, so.. When you glue them together, you can adjust it for length and twist Now just a small bit of filler, that you will hardly notice So there you have it, Tamiya eat your heart out guys, you've got a lot to learn ! cheers Pat 6 6 Link to comment Share on other sites More sharing options...

JOCKNEY Posted December 27, 2020 Author Share Posted December 27, 2020 So having fessed up to having finished this one ages ago, here's a few more pictures The undercarriage legs are completely useless, looks like one had been broken and glued badly by the kits previous owner and the other leg was badly deformed. Therefore I've decided to fall back on an old favourite, 2.5mm copper cable, bent to take the wheel and I will drill the inner wing to accommodate it. No prizes for looks but functions ok, sounds like me come to think of it ! Also managed to extract something resembling a canopy from the vacformed plastic bubble that came with the kit, blue tack and a new blade. Finally, lots of sanding and refilling, not perfect by any means but starting to get better I've been giving some thought to colours, so thinking of doing the later 2 tone grey rather than the earlier green and brown. As it never got to fly and couldn't have done until they designed and built a suitable engine, it would likely have ended up the later colours in any case. More later cheers Pat 6 Link to comment Share on other sites More sharing options...
JOCKNEY Posted December 28, 2020 Author Share Posted December 28, 2020 Bit more done last night / this morning Made and fitted the undercarriage, tried my best to get the canopy to fit (failed) lost the will to live sanding and filling, so decided to get some paint on to lift the mood. Big push today to get it finished ! cheers Pat 2 Link to comment Share on other sites More sharing options...
AdrianMF Posted December 28, 2020 Share Posted December 28, 2020 If you can get the windscreen on there’s always a canopy open option. We don’t know what it’s meant to look like so anything from the spares box glued on anyhow will work, just as long as you tell us it’s carefully researched from very obscure sources...

JOCKNEY Posted December 28, 2020 Author Share Posted December 28, 2020 Thanks for the tip Adrian, started masking the canopy Please don't look to carefully at the areas of filler, I will revisit these another time as they are definitely as rough as a badgers bottom in places, however I'm determined to finish it. 1 Link to comment Share on other sites More sharing options...
