Generally speaking it is a very good kit which combines very good value for money. On the other hand, I would appreciate more delicate panel lines, but we can't have everything. Since I have always wanted to build an Argentine A-4 during the Falklands/Malvinas War I started at once.
Originally, I removed the kit main parts from their sprues and consequently I started a thorough examination by comparing them to the Argentine aircraft photographs that I had already accumulated from various sources (thank you all). My findings were interesting. The reinforcing plates and the nose panel located in the middle and the front part of the starboard fuselage respectively had to be removed in the former case and filled-in in the latter case because there were nonexistent in the Argentine aircraft. Then I re-scribed the panel lines were necessary.
As far as the aerodynamic fairings located on the spine of the aircraft and the lower part of the fuselage as well as the antenna found on the vertical fin, all of which are customized modifications for the Argentine aircraft is concerned, I will comment further at a later point as construction of the model progresses. Now that I am done with the prerequisites I will proceed with the kit's cockpit which is complete but not good enough for me. I own an Aires, A-4E resin cockpit set though, which I liked it a lot because of the side wall and the aft cockpit components for which I believe are similar among the A-4 early versions.
Up to now I didn't have the chance to see a photograph of an Argentine A-4P cockpit. However, based on the fact that the Argentine A-4Ps were refurbished machines that some of them were delivered during late 1960's early 1970's that combined characteristics of the later Skyhawk variants such as the flap/spoiler assembly I assumed that using the Aires set would be an acceptable solution.
From that point on I extensively used my reliable Dremel motor tool to remove a lot of plastic from the cockpit inner walls. I spent much time in doing so. Finally when the sides became very thin, nearly transparent I was satisfied. I also removed very carefully the excess resin from the Aires set and lowered the front wheel well by a millimeter or so. After putting a lot of effort I managed to fit all the above sub-assemblies in the heavily modified cockpit in a very acceptable way.
With the fuselage complete I will next work on the wings. While I was working on the A-4P wings, I received an email from an Argentine modeler, Mr. Pablo Ziegler, primarily concerned with the reinforcing plates which I have already removed. Pablo indicated (and his indication was accompanied with some close up photographs) that all "late" Argentine A-4Ps were equipped with the plates. In the process I have asked him if the "early" A-4Ps were refurbished to the same standard and furthermore if he could provide some serial numbers for both the "early" and "late" aircraft during the war in order to reach a sound conclusion. He replied that he did not have such material and that was too hard to find such information.
After a lot of discussion on this issue we reached the conclusion that most probably during the war all aircraft should have been equipped with the plates. Airfix plates are very thick and the best way to represent them correctly is either to trim and make them thinner or better to completely remove and make them from scratch. Pablo was kind enough to provide some more information that I will refer to when the time comes. At this point I wish to thank Pablo very much for his valuable information which will greatly contribute to make this project a more accurate replica of the real aircraft.
I also take the chance to invite all fellow modelers to feel free and make their comments provided for they serve the above mentioned goal. After this absolutely necessary prologue, it is about time to go on with the development of the A-4P wings.
While I was going through the Cybermodeler Online's walk around photographs for the Skyhawk I noticed the gun gas diffusion area which is located in the front section of the wing roots. I liked what I saw and I decided to do the same in the kit. Subsequently, I removed carefully the thin plastic membrane that was covering the respective point and then I added two small pieces of plasticard accordingly. It is an easy thing to do which contributes a lot to the better overall representation of the model.
Then I proceeded with the flap/spoiler section. Unfortunately, Airfix does not provide for separate flaps which are extended when the aircraft is parked. Therefore, with the use of Dremel in the first place and various kinds of sanding paper later, I removed the excess plastic simulating the retracted flap.. Then, after studying very carefully the respective area, I scratch built the flaps using .13mm and .25mm for the lower and upper part respectively and at the point where they hinged to the wing, I also add a13mm in order to to replicate the three dimensional effect of the real thing. In my first attempt I glued them with Tamiya glue but I was not really satisfied because in same parts the thin plasticard was crazed. Then my very good friend and fellow modeler Fotios Rouch gave me a clue about using super glue in such thin plasticard parts. So I did and everything worked out smoothly. I went on by removing the flap area that the spoiler actuator is going through.
Yes, apart from the "Charlies" the "Bravos" were similarly equipped with spoilers and as a matter of fact, after spending lots of time in studying and verifying the dimensions in question I rescribed the upper wing area representing this feature. I hope I did it right. While I was enjoying the end of my extended flaps scratch built, I have decided to further develop the specific area. This time I would try to replicate the real shape of the flap aerodynamic fairing while in extended position. Even though this area is hardly seen in the internet walk arounds, I remembered that I have a couple of relative photographs taken at Quonset Point Museum, Rhode Island, which helped me to understand how the whole system works. The end result is what you see in the photographs.
I do not know how all these components will go together when the time for the final assembly comes. I have a strong feeling though that since everything is proportional to the real thing will do fine. Another issue of concern to me was the rear part of the slat inner part which does not end smoothly as on the real aircraft but instead it leaves a step. To correct it, I also used .13mm plasticard rods cut accordingly (see photographs) and subsequently I also glued them with super glue. Then I trimmed the whole area carefully and the end result was very satisfactory. Talking about the slats, I also trimmed down to a third of the original the slat actuators afterwards looked much more authentic.
Another important issue when you want to build an FAA A-4B is the customized antennas and fairings. It was really something that I was looking into for at least two decades. The above situation was vastly improved when I receive again from Mr Pablo Ziengler some photographs from an Argentine A-4B that resides in the Buenos Aires FAA Museum. Even though, they weren't close up photographs, thanks to the digital technology I could manage to get a good idea of their shape and with the comparisons and double checking that followed helped me to reach a sound conclusion.
As you see in the photographs provided, all antennas and fairings were made from scratch using generic materials like Evergreen plastic card. The respective pieces were very small and required very much attention and time in order to do them accurately as possible. Also, I did not have in my possession all around close up photographs and therefore I had to be very careful shaping the components. The most demanding of all was the spine fairing. It was the most demanding and the most tiring to deal with. As you see, I scratch built the basic platform which I gave it the original shape. Then, I removed the rear part and trimmed to a great extend along the lower side of the respective part provided for by Airfix. Then I also scratch built the extension for the reshaped Airfix part and then I joined them together. Finally, on the rear part of the new fairing I also scratch built and installed the small base where the navigation light will rest.
I think that the end result is very satisfying. I do not say that it is perfect, but I certainly believe that it is among the most representative as of today. At this stage I did not deal with the vertical fin elliptical antenna. I leave it for a later stage because I have to verify whether there is a reinforcing plate under it or not.
Now for the VOR/ILS elliptical antenna issue and one more time the photographs that I had in my disposal also coming from Mr. Pablo Ziegler helped me to resolve it. After careful examination of the respective area on the vertical fin I verified that there is a small metallic plate under it, which according to my limited knowledge it was probably added to structurally support the antenna. Therefore, I had to represent this plate on the model. The flat area and the correct angle of the photographs helped me to find the proper dimensions relatively easily. Thus, the result is a very small plate of plastic which was made by using 0.13mm plastic card and further sanding it down.
I used the metal wire taken from a cable with a thickness that looked fine for the scale and I finally glued them together by using superglue. Taking into consideration my presbyopia (still no glasses for me), the most challenging part was the adjustment and placement of the two on the tail of the model!! I spent quite some time there but I finally got it down to my satisfaction.
One outstanding issue I have also mentioned in the beginning of this article was the fuselage reinforcing plates. I remind you that I had already removed them and it was time to do something about it. Since it was about a reinforcing plate, again I used the same method and material described above. The important point here was to reproduce these plates correctly due to their particular shape. Photographic material from the same source came to my aid and I believe that the end result is much more convenient than the original one provided on the kit.
Another area that I slightly improved was the landing gear wheel wells. In the main ones the detail is more than acceptable for the scale and the only thing I did is to add two rods (one in each well) made from stretched plastic sprue of appropriate diameter, cut it accordingly and placed it in the rear part of the wheel wells.
In the nose section things were a bit different. The port side of the wheel well houses has a lot of piping which I also constructed from stretched sprue but much thinner than the rods before. I made six very similar pipes to each other and then I also scratch built from plastic card again a suitable plate that supports them. I consequently made six holes by using a very fine drill and finally I passed all six of them through it. Then I attached the whole unit in the model wheel well. On top of that I also added two additional pipes by using very fine metallic pieces also taken from cable, to represent the "S" shape piping.
Why use metallic material? Because the stretched plastic breaks very easily if you try to give it a different shape than a straight line, whereas the fine metal one is much more pliable, easier to work with and to create more complex works with. My feeling is that with the above mentioned additions the nose wheel well is vastly improved and as a matter of fact looks the part.
Thinking that I had finally finished with scratch building parts so I could go on doing regular assembly, I was very disappointed to realize that another part of the kit should be scratch-built. As you may have noticed from the previously published photographs, the instrument panel coaming as well as the panel itself have been removed from their original place. I did so for two reasons; the first one was that I wanted to expedite the assembly of the kit by putting together the fuselage halves and doing other works simultaneously and the second one was the improvement of the instrument panel and its coaming.
My source of information came again from the famous by now Mr. Pablo Ziegler. Actually, I have asked him for a war period A-4B/P instrument panel photograph. His reply was that the material I received was the only one he had in his possession and he was not 100% sure that is coming from the war time period. Since I had nothing else in hand, I started thinking the way I would replicate it in 1/72 scale.
My first thought was to make it by using Reheat bezels and instruments. After careful study of the bezels I rejected the idea. My second thought was to do it from scratch by using plasti-card as described in some old modelling techniques books. I finally ended up by combining two of the above methods. First I formed the background plate. Then I created a similar plate and started drilling holes which would represent the instrument cavities. The first attempt didn't work at all. The second was better, but it was the third example that was finally greatly acceptable. What you see in the pictures is not the exact shape of the instrument panel. The extra plastic at the sides of the main panel involved was formed in order to fill the gap which is created between the instrument panel and the kit sidewalls. However, the instrument types and arrangement is nearly identical to the real one.
So, after drilling the instrument arrangement in the second placard I chose and applied the Reheat instrument decals. Then I aligned the instruments placed in the sandwiched type instrument panel. As far as the coaming is concerned, I added the bit pieces in the inner part. Then I proceeded by painting the new parts and putting them into place.
To be continued...
