HISTORY

                                                                                                            Born to Be Bad
        Planning an aggressive war of expansion across far-flung regions, the Japanese Navy was looking for an air-superiority fighter with extreme long range capabilities. The specification 12-shi included  range and armament  requirements that scared off all bidders except one-Mitsubishi, with talented head designer Jiro Horikoshi leading the team. The new airframe was built with lightness paramount, as with the available engines  the specs could only be met if every spare ounce was pared off. Extra-Super-Duralumium, an ultra light new alloy, was employed in the main spars. Pilot armor was not considered. To keep fuel capacity at a maximum, no fuel tank protection was used, and a droppable underbelly fuel tank planned from the start. Watching European developments, the J.N. required 20 Millimeter Cannon main armament. One was planned for each wing, along with the usual 2 7.7 machine guns. Wanting to use a company engine, the Mitsubishi Zuisei 13 powerplant of 870 hp  was installed in the machine.  As there was no airfield adjacent to the factory, the aircraft had to be disassembled and transported (allegedly by oxcart!) 25 miles to Kagamigahara airfield in Nagoya. Mitsubishi's legend first took to the air on 1 April 1939.
 
Except for top speed, the fledgling fighter performed well, exceeding the 12-shi rquirements. One problem was a dangerous vibration, another poor lateral stability.A second slightly modified prototype was added to the test program, this crashed without explanation, but testing went on.   The vibration problem went away when a three bladed propeller replaced the original two blade unit, the stability fixed by lengthening the fuselage and redesign of the rudder and stabilizers slightly. The more powerful, but Nakalima designed Sakae 12 engine solved the speed problem.  Thus appeared the familiar Zero-Sen, conqueror of the Pacific.
THE KIT

           Been waiting for this one since Hasegawa released the all-Zero boxed set that included all their Zeroes and two new ones, the two seat trainer AND the 12-shi prototype. I never even saw this set, never mind being able to afford it, so the wait was worth it. Six sprues are in the box, one of which is clear, one a new 12-shi cowling and one containing the new fuselage halves which are the prototype's main difference. Sprue V has new stabilizers,  scoops for the first or second versions,  the Zuisei 13 engine, and the neat 2 blade prop. Decals are provided to represent either of the first two A/C. 

                                     Now that it's in my little hands, I realize how little information is available on the Mother of all Zeroes. I've never seen a photograph, and publications over the ages have different takes on how it looked. My ancient Arco-Aircam book has it in blaze Orange, with a "2" on it's tail. Other sources say grey, now I'm told Mr. Horikoshi said it was "Ash Green" on roll out. Hasegawa calls for "grey green".  I am left with several questions on mechanics. All feature a scoop on top of the cowl, where this Hasegawa kit does not.  Two types of under fuselage fin strakes are given, neither of which looks like a tail hook. The box art features the obvious headrest of all Zero models, but the assembly plans ignore it, and the parts on the sprue layout indicate "not used". Huh? Hasegawa is a great outfit, but can sometimes leave me scratching my head.
CONSTRUCTION

         Let's cut sprue on a prototype. After drilling out the lightening holes in the seat,  all the cockpit parts were painted Tamiya "cockpit green", gloss coated, and the kit decals used for the instruments. They fit well. I find Hasegawa Zeroes all have the seat too far forward, move it back some by trimming the mounting lumps underneath.  It should be about an eighth of an inch from the bulkhead. After detail painting a black wash was applied to the areas, and then assembled. I left out the machine gun butts parts E34 and E35 and the gunsight as I assumed (uh.oh) a first prototype would not yet be armed. Fuselage and wing assembly, with it's wheel well insert, fit well with minimal seam cleanup. .At this point I decided to put on the controversial headrest as carrier planes needed such things. I hope the plans were in error.
 
The machine gun insert in front of the windscreen needed some minor filling work. Sonofagun, ready for paint already! I would recommend the Hasegawa Zeroes as a first kit for anyone.
COLORS & MARKINGS

           Controversy again. I decided to go with Jiro Horikoshi's memory and use "Ash green" For this I went with Model Master's Japanese Army Light Green, which is close to Tamiya's new J.N. Green/Grey. (I hate using Acrylic paints unless absolutely necessary). I applied this straight, no shading of any kind, as we are dealing with a brand new kite here. I sprayed the interiors of the landing gear doors and wheel wells aluminum, then gritting my teeth, oversprayed with Tamiya Clear green/Blue Acrylic, mixed thin. This represents the "Aotake" preservative well to my eyes. The cowling was sprayed flat black, and all oversprayed with Testor's Metallizer Sealer as a glosscoat prep for decals.

           Decals are done by Cartograph. They are a bit thick but work OK, settling down with light application of Solvaset. The wingroot "NoStep" stripes were a bit fiddly, but I got 'em. I laid on a panel line wash of my sludge mix, and brought it back to the assembly hall.
FINAL ASSEMBLY

            I glued the engine assembly on, and after some drying time attempted to put the cowling over it. I found it very tough to get over the engine, and after a couple of minutes the front part of the engine came off. Did I do something wrong? Taking the thing apart, I thinned out the areas of the cowl flaps that I noticed were too thick anyway. Leaving the engine loose in the cowling, I applied glue to the rear of it, and installed the cowl and engine at the same time, lining everything up until the glue set. Tricky.

            Landing legs were sprayed black, with silver hydraulic rods. Gear doors were attached to them, then installed. Now everything got another Metallizer Sealer coat, left glossy for that "new plane" look. The canopy work starts now, (the part of WW2 models I hate).  These were really hard to mask using my usual method of placing Tamiya tape on the area to be done, then cutting on the frame lines with a new #11 blade, due to the very lightly engraved lines on the moldings. So I decided to cheat. I cut long, thin strips of tape and laid them out along the frame lines, first the vertical ones, then BRUSH painted them. After these dried the tape was removed and the horizontals done the same way. It got a bit hairy on the curved bits and really was just as aggravating as regular masking, but finally it was job done. A set of Eduard masks would come in very handy here, if they are available.

               I sealed the decals and wash in with another coat of sealer, then installed the canopy parts with white glue. They fit well. The sliding portion WILL go over the back glass if desired, but I closed my canopy as I thought it looked sleeker that way. I then installed the antenna, it's wire of 2 pound fishing line, and pitot tube. Very important for testing to know the airspeed, right?
CONCLUSIONS

               Nice. Actually a typical Hasegawa Zero, a very easy build except perhaps for the fiddly cowling. I absolutely cannot say if it looks right or not, because I've never seen the real thing. On this one we are totally dependent on Hasegawa's sources. On it's own though, I think it is a nice-looking plane. Very clean of line, the shorter tail and 2-blade prop gives it a real "early monoplane" look. One can see how the early reports of Zero encounters referred to them as "Seversky-type" fighters. Recommended as an easy model if one wants a break from a huge project, or just a good looking airplane model.
