Tom R Posted October 21, 2020 Share Posted October 21, 2020 What is the best way to do a 1/72 Wildcat FM-1 version? Should I use the Hasegawa kit and ignore the incorrect (?) rear fuselage and tail - too small by some plans. Is it really too small? Or should I convert the Arma Hobby FM-2? I think I need to change just the cowling? Are there other alternatives? Link to comment Share on other sites More sharing options...
Geoffry M Posted October 22, 2020 Share Posted October 22, 2020 fm-2 had a taller tail too to compensate for the more powerful engine Geoff M Link to comment Share on other sites More sharing options...
occa Posted October 22, 2020 Share Posted October 22, 2020 The FM-1 had the smaller tail like all the earlier versions, only the FM-2 hat the taller fin, I don't think the Hasegawa has an incorrect tail rather a minimally too small nose if anything even. 1 Link to comment Share on other sites More sharing options...
Chuck1945 Posted October 22, 2020 Share Posted October 22, 2020 The FM-1 was an Eastern (General Motors) produced F4F-4 but with only two guns per wing instead of the -4s three guns. The weight and space savings from reducing the number of guns permitted more ammo to be carried. Use the Hasegawa kit but only go with two guns per wing. The FM-2 is a different bird, no oil coolers under the wings, different engine and cowl and the taller tail. 1 Link to comment Share on other sites More sharing options...
RJP Posted October 22, 2020 Share Posted October 22, 2020 I don't think I've heard the Hasegawa kit's tail was too small for any Wildcat prior to the FM-2, perhaps check against a photograph or reliable drawing. That said, reworking the fin isn't much of a problem, a knife and file to cut down the FM-2 tail. The challenge is all up front and that's a lot of mucking about. As noted the FM-2 had a much different, shorter chord, cowling to accommodate the single row engine (and the fuselage aft of it lengthened to make up the difference). Add to that the different exhaust arrangement and different prop. And of course you'd need to source a two-row R-1830. I'm not sure I'd balk at the Hasegawa kit as you''d really only need the gun alterations which are pretty minor. Link to comment Share on other sites More sharing options...
Luka Posted October 22, 2020 Share Posted October 22, 2020 What about the Airfix Wildcat starter kit? That's exactly an FM-1; only thing you'll need to do is replace the national insignia, as these are incorrect (which is quite ironic in a starter set if you ask me).

Thread of mine in the Ready for Inspection section; Not quite, the FM-1 only has two guns per wing, while F4F-4 has three guns per wing. Whether you base an FM-1 model on either the Airfix or Hasegawa kit, the outboard gun goes. US Navy fliers objected to the change in armament when the -4 replaced the -3’s four guns with six. If you couldn’t hit your target with four guns, six wouldn’t change much and the extra guns caused a significant reduction in ammo/gun Link to comment Share on other sites More sharing options...

The Airfix starter kit is conveniently one of those equipped with six.

Chuck1945 Posted October 23, 2020 Share Posted October 23, 2020 Not arguing but are you sure that isn’t a F4F-4? 1 Link to comment Share on other sites More sharing options...
Dana Bell Posted October 23, 2020 Share Posted October 23, 2020 (edited) Hi Luca, That is indeed an F4F-4 - it was photographed on Core on 27 Sept 1943. The unit was VC-13, which flew only F4F-4s between September 1942 and November 1943. I did a good bit of primary research on the Wildcat, but I don't remember seeing anything about six-gun FM-1s. Do you have a citation? Cheers, Dana Edited October 23, 2020 by Dana Bell typo 2 2 Link to comment Share on other sites More sharing options...

Given a choice, they would prefer to shoot longer. However, things were perhaps a bit more complex. Grumman sought USN permission to adopt also for the F4F-4s the 6-gun layout the British had requested for the folding wing Martlet Mk. II, presumably in the interest of commonality and production speed. British combat experience at the time had its weight in a difficult decision that eventually led to the six guns in the F4F-4. Seemingly the Japanese did not oblige, presenting the USN rather different kinds of targets from those the Luftwaffe and Regia Aeronautica were pitting against the Fleet Air Arm. 1 Link to comment Share on other sites More sharing options...
Gwart Posted October 25, 2020 Share Posted October 25, 2020 Hobbyboss easy kit, Mainly a detailing job. Airfix F4F-4,Spine and canopy need a fix and rest is filling work on the outer wing guns. The more expensive way would be to combine the Airfix parts onto the Arma FM-2 (a tremendous kit,the most accurate Wildcat in any scale).Grafting a new nose,shortening the tail height. Hasegawa while basic still looks nice but looses a lot of accuracy in the lower belly/ nose. Shane. 2 Link to comment Share on other sites More sharing options...

MDriskill Posted October 25, 2020 Share Posted October 25, 2020 Just use the Hasegawa FM-1; no need to "reinvent the wheel" here IMHO. As already noted, the forward fuselage is a bit narrow but really it looks fine. There is nothing wrong with the rear half, you may be confusing it with the re-designed FM-2. And of course all the wing scribing Is already correct. The difference between the FM-1 and FM-2 is more than simply swapping cowls. The whole fuselage forward of the firewall is really subtly different, since the two-row R-1830 Twin Wasp (FM-1) and single-row R-1820 Cyclone (FM-2) engines were different lengths and diameters. I suspect it would be tough to exchange major assemblies between the Airfix and Arma kits, as the fuselages are VERY different in cross-section shape.
