History introduction
The Rogožarski IK-3, a 1930s Yugoslav low wing monoplane single seat interceptor fighter with retractable landing gear, was a product of the design team of Ljubomir Ilić and Kosta Sivčev as a successor to their IK-1/IK-2 fighter.
Assisted by Ing. Zrnić, the design team initiated the design of a single-wing fighter that would be a marked improvement over the biplane fighters then in use. They began work in 1936 under strict secrecy. Wind tunnel testing work was carried out in France, before they submitted the design to the Yugoslav Air Ministry, who then approved construction of a single prototype. Construction of the IK-3 was assigned to Rogožarski A. D. in Belgrade.
The prototype first flew in the spring of 1938.
The IK-3 prototype was powered by a Hispano-Suiza 12Y-29 liquid-cooled supercharged V12, rated at 890 hp (664 kW) for take-off and at 920 hp (686 kW) at 11,810 feet (3600 m) altitude. The prototype was armed with one 20 mm Hispano-Suiza HS-404 cannon and two 7.92 mm FN-Browning machine guns mounted over the engine in the forward fuselage. The aircraft was of mixed steel tube, wood, and fabric construction with the retractable landing gear of Messier design. Its construction was similar to the British contemporary Hawker Hurricane fighter. Six test pilots flew the prototype in a mostly-successful test program (alterations were required to the retractable landing gear and to the engine installation) before the airplane was destroyed in a fatal crash. On January 19, 1939 the test pilot, Captain Pokorni, after a series of aerobatic maneuvers, entered a terminal velocity dive from which he did not recover. The subsequent accident investigation could not find an aircraft-related cause for the accident, and the Yugoslav Air Ministry ordered an initial production lot of twelve aircraft.
At the beginning of the April war, only 6 out of 12 IK-3 from the first production series were operational. One aircraft was lost in a fatal accident before the war (it dived into the Danube River under power; investigators concluded the pilot had blacked out), four were grounded for scheduled services and repairs and one aircraft was undergoing modification to Series II IK-3 standard in the Rogozarski airplane factory. The six remaining IK-3s were assigned to 161st and 162nd fighter squadron (3 IK-3 each) of the 51st Fighter group. The 51st fighter group was part of the 6th fighter regiment of Royal Yugoslav Air Force which was tasked to defend Yugoslav capital, Belgrade. Both fighter squadrons were stationed at Zemun airport.

AZ model introduced this kit at the end of February 2010. There are two boxes available on the market and both available at AZ model web http://www.legatokits.cz/
Basicly it is the same kit, and the only difference is boxart and decal sheet. Plastic looks very nice, and the level of details is great.
This model is now the only available plastic injected kit on the market.
-
And the second box preview...
let's start building these kits :)
-
Although I have 12 models on the bench, I'm joining in with '2158' (the one from the second box), starting tomorrow morning :-ok
The end is scheduled for this year, that's the best I could predict right now... :-/

First at all I hope that you have visit download section of the site and that you have download zip file with pack of the archive images in hi resolution where you could note many of details, starting from construction details of the airplane elements like landing gear, middle flaps, engine close ups as well images of the operational machines. Maybe you have note that material inside zip is quite new...
I get some time to start this build some times ago when we have received pack of the models from AZ Models and I would like to grant special thanks to the company owner who have arrange this material for us. Impression about the kit is really hight- very simple products, all plastic parts on one fret (and one for transparent parts), machinery works on the molds are at very good level and surface details are crisp and good.
Images in attach:
01. no matter which kit you will open, note above post of our moderator, they are same in many aspects and main difference is the decal sheet. Instruction is very good and simply to follow.
02. vertical tail is a little off shape but this is very possible result of the shrinkage, which is common in the injection molding method.
03. fuselage match fine into the overall shape and only point to be note is that lower edge are too sharp on kit and it have to be rounded with sand paper.
04. wings also fit excellent to shape, with minor difference in the shape of the sleeve but as well this will be later cement with fuselage, new sleeve panel could be scribed
05. horizontal tail good shaped
06. small detail on the panel behind the pilot head, note panel which have to be engraved
07. basic coat of all of the interior is the aluminum color with various level of the polishing
08. IK-3 actually have no real floor and dominant bottom area elements are two long surfaces, I left them in metal color and paint around in back, this is fine solution as well I plan to make kit with the closed cockpit and this detail would not be seen through.
Work will be progress later... :-wave
-
impressive most impressive,my young jedi master! :-ok work on my kit will begin probably tomorrow!bloody stomach virus :-help
-
Hope that virus will be gone soon :)
From my side here you are more images of the model in work. No specific point there, all steps show here are just regular work step, like in many other kits. Maybe on simple note that chanel which take air under the nose, should be a little bit deeper and if you more prefer you could close the rear side with the mesh.
-
Here you are some surface sanding details, actually filler sanding. For the first time ever I have try Gunze Sangyo Mr. Surfacer 1200 and it is excellent spray model filler! Cover all scratches and very good to prepare surface for the further preparation like engraving and later painting.

Here you are official review of the kit:

More images of the kit assembly. First image show new material for me, this is automotive tape, dedicated for the acrylic protection and it perform excellent on the same kit. Adhere excellent and I did not have any issue until now. Second image show few of the panels that should be engraved, as you seen I used thin cardboard as template, I cut the with razor blade. Most of you recognize White base and the next two images show the kit with the paint over, mixed from primary colors, in the similar manner as done on real airplanes. As you seen there is bottle of that paint made for other modelers who will going to make the kit build. Next image show my protection of the tail- I really prefer all grey scheme as well it is best fighter scheme we have. So this mean wide flag on tail.
Last two images show main landing gear leg fitted inside undercarriage bay. Two point- first you should cut original leg and again cement it in reverse position. Oleo cylinder was in upper position! Second- cement it on the same edge of the bay. I keep it in proper angle with BlueTack.

Samurai has already written everything about the plane and the model which arrived to me courtesy of the Letletlet website :)) , and I decided, while taking a break from the Klostermann campaign, to start making this model! It is quite obvious that the left half of the fuselage lacks some of the ribs, which have been erased due to bad casting, and this is a shame for a beautiful model of an even more beuatiful airplane, so I embarked on an adventure... I sanded off all the ribs along the entire fuselage and made new ribs from heated sprue according to the technical drawings (gratitude to our mate, No.1! :-love ), everything has subsequently been sanded and brought to the scale. I have already assembled the cockpit, and as for interventions, I decided to add the seatbelts which I made out of Tamiya's cut tape since I didn't have any etched belts. The halves were glued on together, and after the glue dried, they were filled up with super glue. I did not have to resort to the heavy artillery since everything fitted perfectly! Here are some photos of my progress...
-
Well... much cleaner build then mine :)) Congratulation for this very nice start :-ok
-
Great start mate... Hope that I will post some work on mine sample soon...
-
little progres...
-
It looks great so far :-love
-
Yes :-ok
-
I Thank to LLL, No1,Samuraj77 and tenk for including me in this action. :-flo :-flo :-flo :-flo :-flo :-flo
I also made new ribs on the left side, but I'm not so certain how it will go, but I hope after some good sanding and maybe little putty, it will look good at the end. I'll see soon. :-wave

Welcome to the Združena Vežba IK-3 :-clap
P.S. Združena Vežba could be translated as Joint Exercise and this is actually what is mostly called Group Build on many other forums.
-
Lets finish building info on my sample kit. Images description is:
01. note small connectors made of the Albion Alloys thin tubes as well position of the landing gear parts
02. overall view on the kit during landing gear assembly
03. the hero of the day- Albion Alloys tubes
04. for the first time kit stand on its own legs
05. preparing of the rest of parts to be mounted on kit
06. semi gloss coat all over the kit
Best wishes to your builds :-tri

:-tri :-tri :-tri wonderful. This is a prototype, am I wright? :-think :-think :-think
-
No, this is sample no. 3 ;) Thank you :-flo
-
excellent job my friend !
-
:-flo
-
little update :-green
-
Great work lads
-
:-clap
-
My friend fantastic work,beutiful models... :-tri :-tri :-tri :-ok :-ok :
-
polished and spray primer with cosmo lac...
-
Surface test :) Nice :-ok
-
Outstanding mate :-clap :-clap :-clap
-
Phuhhh, Wooowww, Ohohooo! :-obey :-ok :-jump :-clap :-clap :-clap
Dazzling, really dazzling! :-tri :-wave
-
Wow, it really shines like diamond :-ok
I'll start mine after coming back from vacation, but will watch closely your progress (marvels of wireless internet :)))
-
Very little progress of mine :-wave
-
that's the spirit my friend! :-flo full speed ahead :-tri
-
Thanks oh guru! :-flo I started to sand it to a proper thickness, but one piece fell off. :-wall
It was not glued well - any weakness is avenging, it just takes time. :-/
I put new part only there (that is what I wanted not to do, but now there is no other way - I will mend it somehow. :)) :-wave
-
After longer time I continue work: finished correction of surface ribs on the left side (hm, hm, :-/ it is not something special, but it will work - those ribs are not so sharp looking, because they were under canvas), and I started cockpit. :) :-wave
-
And little more...
-
Good hand brush work :)
-
Thanks! I wanted it to look a little bit "used". :))
-
Very slow progress! :-red
-
What is the point of the hole?
-
You probably mean on the red arrow and red circle - point is that it didn't fit good, first it was not parallel, and then when I rotated it minimally it was OK, but still was not in the same surface. Look - these are so small things, but as I am afraid of any mistakes that can after show like big, I am bloody careful. :-green This morning I scraped it lightly with a scalpel and it is quite OK. :-wave
-
Go ahead :-ok
-
progres!wind in your sails! :-flo

I try my best - lot of guest now days at my place, then yesterday my wife's birthday - lot of grill, wine, beer, hot paper, cakes, bunch of people all talking, talking, and me serving, serving... luckily one friend of mine that is working in one aviation technical center came and showed some photo's; man, no chance to think about modeling... I slept this night like a baby, after lot of good wine. ;) This morning - some progress :-jump
Inside color had some kind of black wash (according to my attitude this time, that it's the model of little but "used" airplane - so to say not fresh from factory). It will be worked on it more because it looks maybe too dark - I couldn't find correct color and I used blue gray one but it is not Federal Standard number that is in instructions. I'll see, if I find the one than no problems, if not, there will be some color alchemy :)
Instrument panel needs to be softened and painted with flat lacquer so it will lay down better (I suppose).
I had to put all those pegs to glue wings properly; and that's it...
:-flo :-wave
-
Food, drink... the way of life :-ok And IK-3 of course ;)
-
:-ok :))
By the way, anybody this days near my place is invited on table - still have a lot of fine things - it can't stay to long (some thing when cold are excellent for good "mezetluk"), and wine to. So, guys: banzaiiii! :)) :-flo :-wave
-
Tomorrow... :))
-
;)
-
some paintwork :))
-
Nice update :))
-
:-ok yessss! yessss! :-jump :-obey :-clap :-clap :-clap :-clap :-clap :-clap :-wave
-
Finally one little move from me: belts are done :), not a big deal, but still I say that I'm alive :)) :-wave
-
As I could see, you will very soon start with work on fuselage ;)
-
You are wright No1, but this my soon lasted so long. Finale cockpit is finished and assembled - it was not so easy as I thought (it is not clear where exactly to put it, very far from ideal), but somehow it will fit. :) :-salut :-wave
-
Good level of details my friend :-clap
-
Thanks man :-flo :-flo I try my best :-salut
In fact problem was to assemble all correctly, so I had two attempts. It is not very clear how it all goes, would be better if they did it more precise. Anyway it will fit somehow. ;) :)
Here is the rest of photo's :-wave
-
Finally, I found some time, and assembled fuselage and than fuselage and wings...
-
Strong clamping :))
-
Strongest I had :) I think I need to buy something more useful instead of these clothe pegs. :-think
-
The Circle is Complete :))
-
Wonderful build :-clap :-ok
-
Great work mate
-
Superb! I spoke, haugh! :-wch :-ok :-ok :-ok :-obey :-obey :-obey :-wave
