F7U-3 Series Model Kits - Fujimi 1/72

9 October 2024: I've made detail changes to the text and added illustrations with more to come

10 October 2024: Lots of changes; now I await comments and corrections

11 October 2024: Revised Fujimi -3M Pylon Shape modification

In our F7U-3 book (click HERE), Al Casby and I had intended to include an appendix covering all the F7U-3 series model kits available. We decided to cut it in part because of the size of Al's F7U-3 kit and toy collection ("I’ve got enough material and photos to do an entire monograph on them") but also because of the transient nature of the availability of even the more recent plastic and resin kits. 

However, before we decided not to, Steve Ginter and I had created draft text describing most of the model kits and obtained or created illustrations to accompany it so this post and a subsequent one have the benefit of that.

Fujimi released 1/72 scale injection-molded kits of all three F7U-3 Cutlass variations, the -3 (also released as a Testors kit), -3M, and -3P. These are excellent kits, providing positionable ailavators and leading edge slats and a two piece canopy. With few exceptions, they are accurate straight from the box, there are corrections and aftermarket improvements. Fujimi wasn't helped by inaccuracies in the Vought PR-issued three view drawing or refurbishment of the F7U-3 in the Naval Aviation Museum at Pensacola (click HERE and HERE for details).

This is Paul Boyer's build of the F7U-3M.

 

F7U-3: The kit includes the belly-mounted rocket pack, inboard pylons, and 150-gallon external tanks. It is missing the inflight refueling probe that was added to many (but not all) -3s.

 As shown above, the F7U-3s had the early probe tip that resembled a nipple rather than a ball:


The cockpit is satisfactory but can be improved with Obscureco's F7U-3/3M Detail Set, OBS72030: click HERE.  It's not listed on his website but you can contact Chris at bucholtzc@aol.com.

Eduard produced a sheet of photo-etched parts, RES-IM No PE72009, to detail the cockpit, landing gear, etc.


Brengun and F4Models produced photo-etch boarding ladders, BRL72191 and FM7015 respectively.
 

Neither Fujimi or Obscureco do the instrument panel justice but it would difficult to do so in 1/72 scale. Probably the significant improvement would be the addition forward of the top of the instrument panel of the projector that put the gun-aiming image on the windscreen.

 

The radome shape when viewed from the side is just a little off, hardly noticeable if at all. This is a comparison with a very good Vought drawing. However if you want to tinker with it, the upper side needs to be a little steeper and a bit added to the lower side so it is even less symmetrical.

Note that this is F7U-3M forward fuselage part that has a vent halfway back along the left side of the canopy. Unfortunately the vent is not on the corresponding half of the F7U-3 part (at least in my kit), which is an error for most -3s.

The self-boarding pegs alongside the left side of the fuselage were extended whenever the landing gear was down. They aren't represented in the kit but are easily added.

The fairing at the base of the windscreen may also be enhanced. At the moment, these are the best pictures that I have to illustrate it:

The little mast at the base of the windscreen, located slightly left of the center line so it is behind the left frame of the windscreen, is the Davis barrier activator, aka guard. It should be added.

I haven't taken a close look at the kit to be sure that the radome cross section is correct, but this photo suggests that the radome tip is a symmetrical oval angled slightly forward (see the refueling probe picture above) while its aft end is slightly narrower at the top compared to the bottom in order to provide a little more visibility over the nose for a carrier-landing approach.


F7U-3M: Ironically, the kit includes the inflight refueling probe that could not be used on the -3M because of the larger radar antenna in the nose. The instructions state that it is optional but it was not like it was on the -3s. Fortunately, no hole was added to the radome for it. One excellent change is that the inlets have the lower intake lip modification for more thrust at approach speed. Some -3s also received this modification.

This kit provides the requisite pylons and Sparrow I missiles but these are not accurate in shape or the location of the missiles on the launch rails.

First, the missiles are too short, scaling to 135" rather than 150" in length. The pylons and rails are undersized to match.

Much better Sparrow Is are resin parts produced by RESKIT, RS72-0319. These are accurate in length and have the wave guides that were on each side of the missile. Also included are a decal sheet and tiny photo-etched rocket nozzles. However, if you elect to replace the missiles, the pylons/rails need to be replaced by slightly larger ones. I couldn't find drawings of the pylons or the launch rail but I did have pretty good pictures of the missiles on the pylons and since I did have an accurate drawing of the Sparrow I, this is the result:

Second, the Sparrow I launch rails (highlighted in blue on the color illustration above) on the inboard and outboard pylons are different lengths. They should be the same length. Scaling down my drawings to the length of the results in these red-line changes to the pylons/rails (cream) so the Fujimi missiles (blue) are correctly located with respect to the launcher rail using the slot in the missile and corresponding "peg" on the bottom of the launch rail (cream). However, the yellow/red line denoting the upper side of the pylons may not be accurate with respect to the kit's lower wing surface: The inboard Sparrows should be level and the outboard, nose slightly down as shown above and in the second illustration below. I suspect that the top of the kit's inboard pylon should be left alone for example and the locator pegs for the outboard pylons moved aft as shown in yellow so the leading edge of the pylon is just aft of the aft side of the closed leading edge slat.

 
Since the missiles are only about 3/16" (.47 cm) short, that seems like an easier solution to a more accurate installation than creating new pylon/rails for the resin missiles.
 
One thing I discovered in the process was that the outboard missiles were angled slightly downward relative to the inboard missiles by means of an adapter (which is missing in early pictures of the F7U-3Ms) between the pylon and the launcher rail:

My guess is that this was necessitated by the importance of having the missile, which was initially unguided, in a relatively small window out ahead of the Cutlass after being launched so it would be in the radar beam pointed at the target and then be guided to it. It may be that the relative wind at the outboard pylon was different from that at the inboard pylon so a missile there had to be launched at a different angle.

The Sparrow I launch rails look black but this photo suggests that they are really the dark blue of the prior overall blue color scheme (in another color picture, however, they appear to be black).

 

Because the F7U-3M did not have a radar scope in the cockpit, its instrument panel was not notably different from the -3's, particularly in 1/72 scale.

F7U-3P: The -3P comes with a good representation of the photo nose and also the inboard pylons and 150-gallon external tanks.

 

The engine inlets provided have the cannon muzzle openings deleted entirely and do not have the slight bulge aft of the inlets where the photo-flash bomb ejectors replaced the cannons. The -Ps retained the muzzle shape on the upper inlet lip with the muzzle openings and gun-gas outlets aft of the inlet blanked off.

The instrument panel provided is the same as the ones in the -3 and -3M kits and therefore does not have the prominent periscope viewing screen at the top center of the instrument panel (this is a picture of the mock up):

  1. Hi Tommy,
    Thanks for this post! I got your wonderful book yesterday and could not help bringing my Fujimi boxes on top of the project's pile... The paint scheme description of the "unpainted" scheme is priceless! (as so many other things in the book)
    As for the -3P dashboard, I do confirm that it is identical to the other boxings (it is on a sprue common to the 3 kits).
    Thanks again for your precious work, in books and in your blogs.
    Best regards,
    Guillaume
