Grumman was asked to develop a lightweight fighter for use aboard CVEs, and that project, originally XF4F-8, was transferred to General Motors (already producing the FM-1, similar to the F4F-4 but with only four guns) as the FM-2. The most salient feature of the variant was the replacement of the Pratt & Whitney R-1830 two row radial for a Wright Cyclone R-1820 one row (which demanded a different cowl), a different exhaust arrangement and some aerodynamic refinements. Eventually the most produced of all variants, with 4,437 delivered, it performed yeoman’s work in the ASW role within US Navy composite squadrons, never in the limelight exception made of the gallant stand of the CVEs of the three “Taffies” of the Task Group 77.4 against Kurita, in the “Battle of Samar” phase of “SHO 1 Operation”, a series of battles collectively known as “Battle of Leyte Gulf”, where –I assume- the fighter component was composed by FM-2s, and even that is overlooked.

Use of the Wildcat VI by the Fleet Air Arm was a bit more proactive, especially in the late phases of the North Atlantic campaign, where both Mk. Vs and VIs from no less than half a dozen escort carriers, including 882 Sqn’s Wildcats aboard HMS Searcher, took part as fighter cover for attacks against shipping all along the Norwegian coastline. Later the carrier was designated and even undertaken a refurbishment for Eastern service, though it only arrived there in August 1945, operating until October, together to her faithful 882 Sqn.


Only little short of the acclaimed Tamiya kit, Hobby Boss Wildcat kits render a good, fairly accurate replica of the original with minimum fuss and low price, including the early non-folding wing variants. However, this particular kit, No. 80330, is the least accurate of them all, having the special FM-2 features very poorly represented. Sometime ago I built this kit OOB, and the result, though unmistakably different from the rest of the Wildcat models, is not really accurate. Vector came to the rescue with a resin conversion and upgrade, which is gorgeous and really justifies the oddity of the “set to convert the kit into itself”. Having the set at my disposal, I set to rebuild the kit into a better representation of the FM-2.


I rebuilt the cockpit, using the customary Eduard PE set (FE246, for the Tamiya F4F-4), plus the equally customary Squadron vacuformed canopy (9505, for the Monogram kit). A FAA machine should have British seatbelts, so I used the ones in Eduard 49006 (after pondering options, I did not use the Sutton, but the “RAF late”, as shown, for instance, in Eduard’s recent Hellcat I/II boxing). I also worked a bit the gunsight, adding knobs and cables, and placing it on the lip of the coaming instead of in the middle of it; I have seen both configurations, but this gives a better sight of the device. The whole was painted in Xtracolors Interior Green.

The heart of the conversion involves sawing off the nose of the kit and replacing it with the resin piece, which is presented as the complete “barrel”, so you have to glue the fuselage halves first. This certainly diminishes your chances to get a good fit and inevitably some “steps” developed, which were filled and smoothed with putty. The resin piece looks a bit smaller than the fuselage in diameter, which later complicated the fit of the wings (the foremost part of the wing fairing comes in the resin nose) The fit was reasonable and could be smoothed. The inside of the wheel well and rear engine accessories compartment is somewhat different to a P&W, lacking the intercoolers to begin with, and having instead a prominent oil cooler, included in the conversion set, together to a number of engine bearers. As I had the compartment already built, I made only the most substantial changes. To this “barrel”, the front firewall is added, and, to it, the rear of the engine. I added some cables and ducts to give a busier look, but even looking intently from the wheel well openings, the end result is very complete. Everything was painted Xtracolor Interior Green.

Then come the engine, a gorgeous piece made of the central core, and the nine cylinders. The cooling grilles and frontal ring and accesories are provided, but you have to add the rockers and ignition wires. This is glued to the firewall, but I rather fit it into the cowling and only then glue the whole assembly into the firewall; I thought I would have more juggling margin that way. It worked, but the exhaust pipes threatened to throw the cowling too low; I had to sand and finally practically bury the lower ones to keep the cowling in line to the top of the fuselage. It sits nevertheless leaving a noticeable gap in between. I pondered replacing the propeller with the Cutting Edge product, but decided against after carefully looking at pictures; the kit’s one looks fine.

Wings were carefully glued then. HB has the wings as separated pieces, while Tamiya has them in one piece to the lower fuselage. This ensures perfect diedhral; though I had no problem with the diedhral of any HB Wildcat I built, in this case the conversion meddled with the wing’s fairings. In the event, I had to make some hair-rising corrections with the kit already painted, but thing ended up well. The conversion set also provides the rudder, which is much better shaped than the kit’s, but it is noticeably slimmer than the fin. I solved the problem by gluing it deflected, which masked the difference. The three landing assistance lights on the underbelly were absent and were made by gouging a recess with a suitable sized drill, painting it Silver, then in the appropriate Tamiya Clear colour, then making a “lense” with a drop of White glue.


After pondering making a EDSG/DSG machine, the potential mess of the putty (Tamiya and Mr. Surfacer, on which I had rescribed panel lines and some rivets) on the smoothed over nose made me choose the overall Sea Blue Gloss JV884. In the end the nose was well faired over and virtually no blemish was on sight. I used WEMM’s FS25042. To give the finish some interest, I preshaded the primed model heavily in both dark and clear colours, both masked and free hand. I insisted specially on moving surfaces and the wing fold. The paint itself I made “mottle fashion”, and some post-shade with a lightened version of the colour was made. The real paint was very tough and not prone to weathering, but the model would look simply too plain that way. The White ID bands were painted over the dark paint, giving and “instant fading” effect. FAA decals were sourced from the Techmod 48051 sheet, dedicated to the Wildcat VI, with five machines, three in EDSG/DSG/Sky and two in SBG. I applied a thorough glossy coat using Xtracrylix Gloss Varnish with a handbrush. The decals are very thin and care is needed to handle them, as any good quality decal.


The Vector set really wins the day; without it, the model looks like a hybrid lacking many of the subtle characteristics of a FM-2. I wouldn’t advise to build any FM-2 HB kit OOB without it. Pity, for the rest of the family are very accurate and this one provides all the relevant pieces as new moulds. The differences to a FM-1 or Wildcat V are very noticeable indeed, especially the width of the cowling opening and the tall rudder.
