3 November 2015: It turns out that there was a difference between the early FJ-2 ADF system and the FJ-3's: see http://tailspintopics.blogspot.com/2015/11/fj-3-canopy-details.html
25 August 2014: Someone occasionally asks if the F-86H is a suitable basis for an FJ-3 conversion. I've posted some thoughts on that here: http://tailspintopics.blogspot.com/2014/08/north-american-fj-3-redux.html
12 April 2012 PM: I've added some Craig Kaston pictures of the Chino FJ-3 which illustrate some of the points I was trying to make about the CLE wing...
The bottom view illustrates most of the additions and changes to the fuselage and wing for carrier-basing. The difference in landing gear doors was required due to the nose gear length increase and the main gear stroke increase. The length of the wing slats changed to accommodate the wing fold. The horizontal tail was increased in size for lower approach speeds.
The Sabre wing went through many changes, with one change being the 6-3 hard wing introduced early in F-86F production. For an excellent summary, click Here. The FJ-2 and early FJ-3 wing was the same as the F-86E and early F-86F, with aerodynamically actuated slats. Note that the wings in some model kits may not be the configuration that the kit is supposed to represent.
Click on any illustration for a large, downloadable version. Size the box around the drawing above to 8 inches for 1/72 and 12 inches for 1/48.
I wasn't able to find as good a drawing as I wanted for the F-86 so some of the differences here may just be the accuracy of the original drawings. However, this does illustrate that the FJ-2 vertical fin was moved forward and that the main landing gear was moved aft as a result of the wider tread (also desirable from a tip-back standpoint). The difference in windscreen side-panel area is also significant. The engine inlet was slightly increased in size for more low-speed thrust. Note that the leading edge of the FJ-2 overlaps the ammo door slightly whereas it does not on the F-86. I had originally assumed that this meant that the FJ-2 had the 6-3 wing, but I subsequently discovered that it was the result of the FJ-2 ammo door extending further aft with the change to the 20mm cannon.
Because the FJ-2 was powered by the J47 engine like the F-86 but about 1,000 lbs heavier, its performance was inferior to the F-86's. All the FJ-2s—with an experimental unpainted exterior—went to the Marine Corps, who were very glad to have them.
The FJ-2 was then minimally modified except for the substitution of the more powerful J65 to create the FJ-3. The most notable exterior changes were the deeper forward fuselage and inlet and the change to the small air intakes just aft of the fuselage break.
The inlets don't look that much different on paper in profile but they were notably different in appearance from the front as shown here and in the illustration above:
The early FJ-3s had the same wing as the FJ-2. The leading-edge slats were aerodynamically actuated so they were extended when the aircraft was parked. Like the FJ-2s, the FJ-3s did not initially have the small fences on the wing leading edge that were to become standard on Navy swept-wing jets to insure proper barricade engagement. These were subsequently retrofitted to the FJ-2s and the FJ-3s that were delivered without them.
Starting with BuNo 136118 in production, the slats were removed from the FJ-3 wing and a new fixed and extended leading edge incorporating fuel tanks was substituted. Delivered FJ-3s were retrofitted at overhaul. Like the F-86 wing, the leading edge was extended six inches at the root (center line, not side of body) and three inches at the tip but the new FJ-3 leading edge was also cambered (drooped) downward.
I've annotated this Craig Kaston picture of the Chino FJ-3 to show an approximation of the original airfoil and the location of the leading-edge fuel tank connection. (Note that the flap was not usually down when the wings were folded and 2x4s were not normally used for the purpose shown here.)
With the addition of a mid-span fence, this "hard wing" retained good low-speed handling qualities and maneuverability at altitude as well as providing space for a much-needed increase of internal fuel. The drawback was an acceptable reduction in top speed.
The 6-3 extension resulted in more of an overlap of the wing on the ammo door.
Instead of a bit of the leading edge being part of the door as on the slatted wing, there was only a transition fairing on the ammo door. A triangular piece of the leading edge had to be swung downward out of the way so the ammo door could be opened.
Note: I've yet to see a picture of a blue FJ-3 with the hard 6-3 wing or a gray/white one with slats.
The elevator also got the trailing edge external stiffener treatment during the production run or subsequently (Craig Kaston photos).
The retractable barrier pickup was removed in production beginning with BuNo 141364 since it was unnecessary on angled decks. It was removed on delivered aircraft during overhaul. I have seen one picture of a gray/white FJ-3 with it extended so the color scheme change can't be used as an effectivity break as it can be for the slatted versus hard wing.
As of BuNo 136118, FJ-3s had provisions for two pylons on each wing inboard of the existing ones for external tanks, for a total of six. The FJ-3s were also retrofitted for inflight refueling with the installation of a fixed probe extending from the left wing.
Another major change from the F-86 was the ejection seat. Although the XFJ-2s had the F-86 seat, production FJ-2s and -3s had a seat designed to Navy crash and other design requirements, like the initiation of ejection with a face curtain pull.
As with most of my topics, this one provides only the basics on the aircraft in question. The model builder will probably want to buy or borrow a book that covers the subject in more detail. In this case, Steve Ginter has just published his long awaited monograph on the FJ-3 to complement the ones on the FJ-1, -2, and -4. It is available directly from him, click Here, and from Sprue Brothers, click Here.
A commentary on the drawings: These were created on Illustrator based on North American 4-view drawings of the F-86, FJ-2, and FJ-3; the FJ-2/3 SAC drawings; the FJ-3 fuselage stations drawing in Ginter's monograph: and photos. As usual, there were were conflicts between, and errors on, the drawings so I had to guess as to which one to rely on. Or neither. For example, the horizontal stabilizer on the fuselage stations drawing appears to be placed too high based on the other drawings and photos. What's worse, the planform of the horizontal stabilizer on the page with the FJ-3 stations drawing of the fuselage and wing is that of the F-86, not the bigger one that is on every other FJ-2/3 top view. In this case, I went with the higher stabilizer position but the bigger planform.
The FJ-2 inlet on the North American drawing is the same as on the FJ-3 drawing, when clearly it should be smaller. Even more confusing, the front view of the inlet appears to be more like an FJ-2's and the side view is very like—but not exactly like— the depiction on the FJ-3 fuselage stations drawing. I used photos and an analysis of the SAC dimensioned drawings to determine that the FJ-3 inlet was deeper than the FJ-2's by about three inches and develop my best guess as to the difference in shape of the two inlets from the front.
Another discrepancy becomes apparent on many top and front view original drawings because I can very precisely trace one side of them using Illustrator and then copy and flop it to create the other side of my drawing. The flopped trace rarely matches the other half on the original within a line width and sometimes the difference is notable. Which side of the original is right? Probably neither.
My drawings, therefore, are not necessarily exact and should not be slavishly followed as to shape or even size.
Kit options: So far, the only complete FJ-2/3 Fury kits in 1/72 scale are from RVHP. Now out of production and not readily available, these were produced in resin with cast metal landing gear and a vacuform canopy. There were three different kits: FJ-2, FJ-3, and FJ-3M. I only have the FJ-3, but my guess is that they only varied in the decals provided.The wing appears to be based on the Heller kit, so it has a bit too much sweep and does not have either extended slats or the 6-3 extension. The fuselage has the FJ-3 inlet and the FJ-2 aft fuselage air intakes. There is a detailed inbox-review here: http://alexsmodelling.blogspot.com/2014/12/fj-3m-fury-rvhp-model-kit-review.html
Still available is the Falcon Triple Conversion IX which included a vacuform FJ-3 fuselage, lower inboard wing, canopy, and external tanks. (The other conversions in TC IX were a C-2 fuselage and canopy and an AD-5W radome and aft compartment enclosure.) No decals or landing gear were provided. The instructions imply that the FJ-3 conversion was designed for the Heller kit.
There are several 1/72 F-86 kits. I've converted the Heller kit into an XFJ-2, which requires the least number of changes from an F-86E or early F-86F. As noted above, it has the original wing with a bit too much wing sweep and the slats fixed up. Fujimi produced at least two different variations, one with the 6-3 hard wing (#F-19 or fuj25019) and another with the wing span increase. The 6-3 hard-wing version appears to have more of a 6-6 leading edge extension but in other respects it is an excellent kit. The Hobbycraft/Academy F-86E kit is reviewed here. The newer Academy F-86F kit is reviewed here. The newest kit, from Airfix, is described here.
In 1/48, beware of the Esci FJ-2/3 kit. It has a woefully inaccurate fuselage and canopy. For more details on that, see http://tailhooktopics.blogspot.com/2015/04/esci-148th-fj-23.html.
A more expensive option is the Collect Aire FJ-3, described here. However, it is no longer listed on Collect Aire's web site, so you might consider converting an F-86 kit as described here.
