North American FJ-3 Redux
Since there is a pretty good 1/72 F-86H kit available and it has a bigger inlet like the FJ-3 (it had a more powerful engine), there has recently been a discussion as to whether it would be a suitable basis for conversion. Suitable, of course, varies by individual, ranging from minor alterations to, as the late, great Bondo said, "practice bleeding".
Herewith an illustration of the basic differences (the F-86H has the wing-tip extension and many detail differences but that's no hill for a stepper; the basic empennage is pretty close):
So far, so good. A comparison of the North American drawings illustrates some of the shape and size differences in profile. The FJ-3 lines are in general less dark; I didn't bother to determine if either drawing needed to be resized vertically for accuracy. However, it's pretty clear that the F-86H has a deeper fuselage in addition to being longer.

The consensus was that if you just had to have an FJ-3 now, the Falcon conversion (which is still available) is the better bet; it consists of fuselage halves and a pretty good canopy but no decals. This R.J. Tucker's build combining it with an Academy F-86. Note that the F-86 horizontal tail might be too small. See more photos and a summary of the build here:http://www.arcair.com/Gal1/101-200/gal142-FJ3M-Fury-Tucker/00.shtm
Print Scale put a couple of FJ-3 schemes on an FJ-4 sheet: http://www.internetmodeler.com/scalemodels/nraviation/Print-Scale-1-72-FJ-Fury-Decals.php
As of this writing, the Falcon conversion is available from Hannants and Falcon (click HERE). I couldn't find it on the Squadron or Sprue Brothers website.
The best single reference is Ginter's monograph Naval Fighters Number Eight-Eight:

Draft Tailhook Topics
So if you find interesting things here, you might find more there. In some cases, it was just a convenient place to post answers to questions that were raised on modeling websites, like F9F Panther and Cougar ejection seats, http://tailhooktopics.blogspot.com/2014/07/grumman-f9ff-9-panther-and-cougar.html.

Things Under Wings - Training Wheels
It is a Mk 47 practice bomb dispenser. For more on it and other U.S. Navy armament training devices circa World War II, see http://thanlont.blogspot.com/2014/07/things-under-wings-training-wheels.html

F8F Bearcat Wheels and Wheel Wells
28 August 2025: Added tail wheel information
I've seen a couple of questions on the modeling blogs recently about F8F Bearcat wheel well color, which suggested a post on the subject. Since what I have is not all that conclusive, I thought I'd add wheel hub configuration to the discussion.
It appears that the F8F wheel wells were painted the same color as the exterior with the exception of some hardware located in the well (there was apparently no specific requirement as to wheel well color until they were to be painted white in the mid 1950s).
Although these are grey-scale pictures (the second one has been lightened considerably) and the color pictures I have aren't conclusive because the wells are in shadow, that's the way to bet.
However, some of the very early F8Fs had the accessory section (viewed from the inboard wheel well) painted with either a metallic color or zinc chromate.
And there are pictures of F8Fs at Grumman with non-blue wheel wells so it may be that the wheel wells became blue at the first Navy overhaul.
The two different wheel hubs are distinctive. The early ones had "spokes" and might be either blue, "black" (cosmoline?) or metallic (in this case, on the drop test article, probably unpainted).
The brake pucks were initially located on the lower forward area of the brake disc.
These were subsequently relocated to be at right angles to the strut.
The later wheel hubs were forged, possibly introduced with the F8F-2 and similar to the hubs on the F9F Panther.
The tail-wheel fairing was two piece, an upper/forward fairing that was attached to the strut and a lower/aft one that was attached to the full-swiveling tail-wheel fork that kept a pendant from hanging up on the tail wheel.
The tail wheel retracted into an opening in the bottom of the fuselage so the wheel was barely visible if at all from the side.
Note the strakes on the bottom of the fuselage ahead of and behind the wheel well.

Grumman F9F-8T/TF-9J
This is very welcome since it is one of a handful of U.S. Navy airplanes that have gone unrepresented as an injection molded kit. A built model looks pretty good:

More Modeling Notes on the 1/72nd Airfix A-4B Kit
For an excellent built article of it by "Speedman" on Britmodeler, click HERE. This is a picture from that build:
Airfix had used the A4D-2 displayed on Intrepid as a basis for the kit, including the decals. Speedman decided to replicate that display, even to the point of adding red aileron-control-surface locks.
Neil Lowe posted a question about the Airfix kit on my post on A4D-1 vortex generators (HERE). He noted that there was a detail on the top of the fuselage between the canopy and the red anticollision beacon that is suggestive of the vent that is only present on the J52-powered A4D. I hadn't noticed it before. He also asked about the access panels in this area.
As far as I know, there is no vent in this area on the J65-powered A4Ds (I haven't seen any pictures of the top of the Intrepid A4D but I doubt that it has the vent). This is a picture of an early A4D-1 that depicts this area and the two access panels.
So for J65-powered A4Ds in general, this detail should be removed from Airfix kit. Whether or not you add the access panels is up to you.
