In order to fill the time, here already comes the official WiP section of this build:
The kit and its assembly:This model was spawned by a grain of truth: as will be mentioned in the background, EADS Spain had actually bought a few L-159s in 2009 from the CzAF in exchange for transporters, and together with the ongoing plans of an independent Catalonia I merged both into this ALCA single seater for the (yet) fictional Republic of Catalonia Air Guard.
The kit is the relatively new KP L-159. This is basically a nice model, but the kit has some severe flaws (see below). The model was basically built OOB, I just added AIM-9L Sidewinders and their respective launch rails as external ordnance on the outermost underwing hardpoints. Since I did not find the standard gun pod (a ZVI PL-20 Plamen pod with 2×20 mm guns) suitable, I decided to give the GARC aircraft a heavier, Western weapon in the form of a Mauser BK-27 (the same weapon used onboard of the Panavia Tornado or the Saab Gripen) in a conformal cannon pod under the fuselage. This piece was taken and adapted from a Heller Alpha Jet. Its shape perfectly fitted between the two ventral air brakes.

Concerning the kit itself, the build turned out to be a medium nightmare. The kit looked promising in the box, with fine engravings, but nothing fits well. There are no locator pins, you have (massive) ejection marks almost everywhere, and the parts’ attachment points to the sprues protrude into the parts themselves, so there’s a lot to clean up. At least there are no sinkholes.
Upon assembly, the cockpit tub – nicely detailed – would not fit into the fuselage at all and ended up in an oblique position (hidden through a pilot figure from the scrap box and a re-mounted avionics fairing in the rear cockpit). The air intakes left me guessing, too: while the edges are crisp and thin, the overall fit with the fuselage and the orientation of the parts had to be guesstimated, plus a mediocre fit, too. The instructions are not very helpful, either. I am quite disappointed and tried to make the best of the situation.
Painting and markings:Much more thought was put into the model’s looks. What camouflage should such an aircraft carry? And I had to invent roundels/markings for a Catalonian air force aircraft, too.
Since the Catalonian L-159s were multi-purpose aircraft, yet primarily tasked with air space defense, I opted for an subdued air superiority scheme instead of a tactical low-level camouflage. Furthermore, the camouflage was supposed to be suited for a mountainous landscape (Pyrenees), relatively flat and dry land and also to open sea. This was a good opportunity to give a model the Greek “Ghost” scheme: a three-tone wraparound scheme consisting of FS 36307 (Light Sea Grey), 36251 (Aggressor Grey) and 35237 (Medium Grey, but actually a rather greyish blue). The pattern was adapted from Hellenic F-16s. I think it’s a good compromise, and it suits the ALCA well.

The national markings caused more headaches. I was looking for something that would not look like the Spanish roundel, but still reflect the Catalonian indpendence flag and – most important – I wanted to be able to create it from stock material (not printing them at home), with the option to replicate it on potential future builds.
In the end and after long safaris through my spare decal repository, I came up with a round marking. It consists of an Ukrainian roundel with a relatively thin outer yellow ring (from a Begemot MiG-29 sheet), placed on top of a Hinomaru, so that a thin, red outer ring was added. Onto the central, blue disc a white star (from a TL Modellbau sheet with US Army markings) was added. I think that this looks original enough?

There was a problem, though… In my first attempt to apply this construction, the roundels turned out to be VERY large overall. While the design itself looked O.K. (despite reminding of Captain America somehow), this looked ridiculous, esp. on an aircraft with a wraparound low-viz paint scheme. I was not satisfied, so I heavy-heartedly ripped the decals off again (using adhesive tape, works like a charm) and tried it again, in a smaller version.
Hinomaru became the basis once more, even though smaller, and then die-punched discs in yellow and blue (from generic decal sheet) were added, and finally small white stars again, one size smaller than during the first attempt. While this is still colorful and stands out from the grey background, the second attempt looked much more balanced now, and I stuck with it.

In order to add more flavor, I added Catalonian fin flashes and squadron emblems on the nose, depicting the “burro”, the Catalonian donkey which has become a kind of unofficial regional symbol as a kind of anti-mascot to the Spanish bull. These markings/decals were printed at home on white sheet.
The tactical codes were based on the Spanish system. The Spanish Air Force has its own alphanumeric system for identifying aircraft: This forms a prefix to the airframe serial number, usually marked on the tail. C means cazabombardero (fighter bomber); A, ataque (attack); P, patrulla (patrol); T, transporte (transport); E, enseñanza (training); D, search and rescue; H, helicopter; K, tanker; V, Vertical Take Off and Landing (VTOL); and U, utility. An example would be that the F-18 with "C.15-08" on the tail is the fifteenth type of fighter that arrived in the Spanish Air Force (the Eurofighter is the C.16) and is the eighth example of this type to enter the SAF. On the nose or fuselage, the aircraft has a numeral specific to the unit in which it is based.
Variants of planes in service, for example two-seater versions or tanker versions of transports planes, add another letter to differentiate their function, and have their own sequence of serial numbers separate from the primary versions. Example: "CE.15-02" will be the second F-18 two-seater (Fighter Trainer) delivered to the SAF. In addition, the aircraft used by the Spanish Air Force usually carry a code consisting of one or two digits followed by a dash and two numbers, painted on the nose or fuselage. The first number corresponds to the unit to which they belong, and the second the order in which they entered service. Example: the fourth F-18 arriving at Ala 12 will have on the nose the code "12-04". Those codes do change when the aircraft is re-allocated to a different unit. Quite complicated…
This led to the tactical code “2-03”, for the 3rd aircraft allocated to the 2nd fighter squadron, and “C.1-03” as individual registration as the 3rd aircraft of the 1st fighter type in Catalonian service. All codes were puzzled together with single black letters and numbers from TL Modellbau in 3 and 5mm size.
