Undoubtedly the most important fighter type of the USAAC/F in the first year and a half of WWII. Though outclassed in some respects by aircraft of Japan and Germany, it was a very capable performer at low altitudes. It's rugged construction was also responsible for bringing back many a pilot who would have otherwise been shot down. The initial versions were all powered by Allison engines which were not noted for their high altitude performance as were Merlins of the Spitfires and the Daimler Benz engines of the 109s.

In an attempt to remedy that situation and to offer a common engine to that of British allies, a Merlin engined P-40 was developed. This was the P-40F. Unfortunately, putting this engine into the heavier P-40 did not give the anticipated performance boost that was expected. Nonetheless, 1361 P-40Fs were built. Out of these 699 were the initial run of short tailed aircraft, while the rest were built with longer fuselages. 

AMT embarked on a program of new tool 1/48 aircraft kits back about 1996. They were eagerly anticipated as they offered the F7F Tigercat, A-20 Havoc and P-40 Warhawk series of aircraft. Frankly, I was one of those who bought a number of each type. They were well molded, of interesting aircraft, and were competitively priced. In the P-40 series, there is a P-40F, P-40K and P-40N. While the N has been kitted by Mauve (and frankly, it is just a bit nicer than the AMT kit, but at twice the price), neither the F or the K have been previously done. It is odd that the E wasn't also done, but that really isn't a big deal.

First thing I did was to start getting together subassemblies. In this case it was the drop tank, interior parts and wings. The drop tank and interior bits had a lot of flash on them. Combine that with soft plastic and one needs to be careful not to take away too much. The interior bits fit OK, but the seat has a very odd-looking forward incline to it. 

I needed the tail from this kit for the P-40K in order to make it into an E model. Not a problem as I wanted to do a long tailed L with this kit. Looking at the inside of the fuselage, I noted a nice cut line already engraved. Apparently, AMT was covering it's bets and had planned on doing a long-tailed F before giving up on airplane models.

After cutting that off, the aft fuselage has some pieces of card glued in to offer up a bit of extra reinforcement for the long tail that would be coming from the P-40K kit. I had decided that the best way to attach the new tail was as a whole piece rather than gluing one tail half to one fuselage half first and then gluing the fuselage halves together. Gives me more room to fiddle around in case there is a problem. Having decided that, the tail halves from the K it were glued together and I returned to doing some work on the rest of the kit.

Much of that work involved removing a lot of flash from the cockpit pieces. The seat, instrument panel and armor backing had a lot of it and much careful trimming is required. After removing the flash, the cockpit parts were glued together (except the side panels and instrument panel) and all the interior bits were then painted US Interior Green, an Aeromaster acrylic color.

While that was drying, the engine covers were glued onto the front fuselage. These items do not fit particularly well. With some careful fitting and a bit of trimming, a reasonable match can be made. The result is that there is a bit of a step back on the very front where the panel does not line up with the front of the fuselage. This area was filled and sanded flat so it wouldn't look strange when the prop and spinner were attached. Once that was done, the appropriate 'fish tail' exhausts were glued in behind the engine panels.

The next item for concern is the cooler intake. The kit supplies one with two carb intakes whereas the real aircraft only has one. The modeler has two choices. Either don't sweat it or remove the two intakes and replace it with one made from tubing. That is what I did and it really isn't that difficult to do. The most time consuming part was shaping the butterfly valve. A downside is that this new carb intake interferes with the chin alignment pin and socket. However, it is worth it and really improves the look of the aircraft. Unfortunately for me, I made the intake too large and it should lead all the way to the lip of the intake, which it does not. However, in my own defense, I didn't know this until after I had made it and glued the fuselage together! Apparently this duct sort of snakes down to the twin circular radiators (which I cut off). You can see from the photo up in the kit description how this duct should look.

Now that I had all the pieces for the fuselage, I glued the two halves together, trapping the intake section and the prop shaft. The interior isn't installed until the next step. Good thing, too, as not having it in the way makes it easier to glue the fuselage. Fit isn't too good and I can see that all the seams will need filler. Thankfully, the soft plastic is easy to glue. Once the fuselage was glued and the first filler application was sanded down, the new tail section was attached. This is where the reinforcing strips come in very handy. I aligned the new tail at the top of the fuselage and used superglue to hold the tail in place. The gaps are quite large so more superglue was used to fill the gaps. Then a coat of filler was used to smooth things out. It took quite a bit of work to get things nice a smooth and included several sessions with the filler.

While all that fuselage work was going on, I worked on the wings. First thing that was done was to glued the upper and lower halves together. Fit is quite good. Next, the outer guns were removed. This is one of the things done to lighten the airframe. I wasn't sure if the shell ejector chutes were also filled, but did it anyway just in case. I also filled the holed for the outer bomb racks as I wasn't going to use them. At this time, the 'knee' fittings were glued onto the leading edges of the wings as per the instruction. Fit was OK, but I still needed filler to take care of some gaps.

Next was the installation of the interior. It really was easy and the thing fit well. Again, thanks to the soft plastic, I was able to get it to get a really good join. Then the wings were glued in place. As you might expect, the fit was OK, but not great. There was need for filler and some filing, especially at the front section near the radiator outlet, which was the worst. Filler was also needed at the upper wing/fuselage root. Then the radiator outlet piece was glued in and a bit of filler was needed on this. This is a rather odd looking piece, but since I have no images of the underside of a Merlin P-40, I'll leave it as it is. When that was taken care of, the tailplanes were glued in place. One of mine had a lot of flash on the back and it was also quite a bit thicker at that point than on the other tailplane, which was in good shape. Some sanding took care of that. Fit here was also quite good and no filler was used.

It was at this time that I  decided to do something about the indentations on either side of the nose caused by the slightly short and poor-fitting engine exhaust panels. There are two ways of taking care of this situation. One is to build up several layers of filler and sand the area flat and smooth using sanding sticks. The other option is to use plastic strip to fill in the indentations and then sand the strip flush with the rest of the nose. Since I was building two P-40s at once, I used both these methods. Take a look at the image to the left showing the results of these methods.  Both work well and give acceptable results, so the choice is yours as to which to use. Of course, you could also shim the aft section of the exhaust panel to make the front area flush as well, so there are really a lot of options available for this one! At this time, the gun barrels were drilled out.

Next thing to do was to prepare the transparencies. They are commendably clear, crisply detailed, have flash on them, and have sprue attachment points that are a pain to clean off without marring the clear part.  They are also thicker on one side than the other by a wide margin. Not sure how to explain that one, but since the canopy will be closed, it isn't going to be a factor though it is obvious when looking from the rear!

After it dried, the underside of the tailplanes were masked and the upper surface painted with Olive Drab, again from the Aeromaster line. I had quite a decision to make concerning this color. The desert will bleach a dark color like this rather quickly, so that in a few months it is visibly lighter. However, the one (rather poor) picture in the P-40 in Action book of this plane, shows a relatively dark aircraft, so I used the darker OD, assuming it was a recent replacement, hence the OD/grey paint scheme. The OD was sprayed on with no problems. The demarcation line was freehanded instead of using a mask, though the drawing shows it as a hard edge in the decal sheet. At this time, the gear doors were also painted.

Those decals, when nearly dry, were treated with Champ setting solution. I have always had good luck with Champ and Aeromaster decals and these were no exception. When they were dry, the upper checkers and those for the other side of the tail were put on, and again, treated with Champ when nearly dry. The fuselage insignia is a two part affair. Each part was treated with Champ as were the other decals. When they were completely dry the next day, the model was wiped down with water to remove any excess setting solution. The decaling took a bit over two days, about normal for me when few decals are involved and I'm not in a rush!  Then it was back to more construction and a bit more painting.

The EZ Masks were then taken off. They came of easily and there was only a tiny bit of leakage at one area. Probably the nicest thing about them is that there was NO residue to clean up. However, I did notice that somehow I managed to get glue on the inside of the windscreen between it and the glare shield. Just part of the many disasters that accompany most of my models! The aft windows were installed at this time using white glue. There is a landing light that goes under the wing. This part proved to be poorly molded in that it was about twice as thick as the slot it was designed for. Rather than go through the tedious method of sanding it down, the area was filled with white glue, which gave an acceptable representation of the light. The various formation lights were painted, the radio wire was attached using stretched sprue and the kit was done.
