Some people are desperate for a good injection-molded kit of the North American FJ-2/3 Fury, so desperate that they consider building the ESCI 1/48th kit. While I'm sure that a fairly accurate model can be built from it, some changes will be necessary.
The most notable errors are in the forward fuselage,
It fairs even worse as an FJ-3, because its inlet was even deeper. (And that scoop on the aft fuselage needs to be cut down and a recessed ramp added ahead of it.)
Since the bottom of the sliding canopy has the distinctive "dip" of the FJ-2/3's at its forward end (added to allow the pilot to sit higher for takeoff and landing while closing and opening the canopy) and the inlet is an undersized version of the FJ-2's, it doesn't make for a good XFJ-2 out of the box either. The XFJ-2 had the standard F-86 sliding canopy with a modified windscreen for better over-the-nose visibility. For an overview of the North American FJ Fury family, see http://tailspintopics.blogspot.com/2009/10/fj-fury.html
However, even given its shortcomings, the kit has possibilities. Deepening the forward fuselage wouldn't be too difficult. "Impatient Pete" modified an F-86 with this cut on the way to an FJ Fury in an ARC forums post.
The bottom of the windscreen and sliding canopy could possibly be filed down to lower them to the right height. A F-86 canopy might be even better.
I don't have the kit so I can't say what has to be done to the wings, horizontal stabilizer, etc to improve its accuracy. For those details, see http://tailspintopics.blogspot.com/2011/04/fj23-fury-redux.html
While most of us are content to imagine the possibilities or hope for a new FJ-3 kit, Jon Kunac-Tabinor has not only sallied forth with the Esci kit, he is posting his progress here: http://www.britmodeller.com/forums/index.php?/topic/234981173-north-american-fj-3-fury-148th-esci-with-added-elbow-grease/#
However, Jon is having trouble with the quality of Esci plastic and Bob Sikkel reports that the Esci wing has the incorrect sweep and aileron location. The desperate might want to consider another 1/48th scale alternative, a mash up of the Grand Phoenix FJ-4 and a Monogram F-86. The FJ-4's fuselage was very similar to the FJ-3's (see Jon Krol's comments below and the following illustrations). Bob Sikkel also provided the following comparison of 1/48th kit inlets to which I've added photographs of the actual airplanes.
The FJ-3 and FJ-4 fuselages were almost identical, except of course where it is obvious that they aren't as well as the small difference in downward angle of the 20 mm guns. While the main landing gear was very different, the nose gear appeared to be the same except that the shock strut was more extended at rest.
The wings and horizontal tails were very different, which is where an F-86 kit is required.
