F7U-3 Series Model Kits - Part Two

For an introduction and Part One, which was dedicated to the 1/72 Fujimi kits, click here: https://tailspintopics.blogspot.com/2024/10/f7u-3-series-model-kits.html

 Several model kits of the F7U-3 have been produced, beginning shortly after its first flight. Some are long out of production and now sought after collectors and modeling enthusiasts willing to pay many multiples of a kit’s original price. Note that the vacuum-formed kits consist of plastic sheets from which the individual parts have to be cut out and prepared for assembly.

For more detail on these kits and many others, search for "F7U" on Scalemates 

Vacuum formed

Airmodel 1/72 F7U-3/3P Kit Number 156: A very simple kit with no cockpit parts, decals, or landing gear. However, it is an appropriate basis for creating a manufacturer's desktop model.

 

Rare Plane 1/72nd Scale F7U-3: It is more complete than the Airmodel kit with good surface detail (female mold) but slightly inaccurate in shape and does not include decals.

ID Models 1/32 F7U-3 (subsequently reissued by Tigger Models):Vacuum formed on a male mold so the surface detail is all but nonexistent and complex shapes are not rendered accurately. The manufacturer characterizes them as “very basic canvases”, which is accurate.

Injection molded

 
Revell 1/60th Scale F7U-3/3M Cutlass: First released in 1953, there were several different variations released through 2010. It's pretty crude with raised lines for the placement or coloring of markings.

Hobby Craft 1/48: This kit was first released in 1990 and subsequently released with other decals and/or  photo etched and while metal detail parts. Unfortunately, it has some notable shape and accuracy issues, e.g. the forward fuselage. For example, the radome and lower forward fuselage should not curve upward as much as they do in the kit. The windscreen has too big a step at its front edge and slopes aft at too shallow an angle. The cockpit detail is sparse and inaccurate, particularly the ejection seat. The late Phil (Bondo) Brandt also noted that the afterburners were undersized.

 As a result, several aftermarket improvements have been produced.

Lone Star Models produced a very detailed resin cockpit, that is far superior to the one in the kit as well as a resin F7U-3P nose. However, I was unable to determine their availability.

Reskit also produces a 1/48 Sparrow I missiles, RS48-0319.

CAT4 Scale Model Accessories has produced conversion parts for the detail problems other than the canopy:
R48029—Early F7U-3/-3M/-3P wheel hubs and tires
R48030—Later F7U-3/-3M/-3P wheel hubs and tires
R48040—Corrected radome (no inflight refueling probe)
R48041—Corrected radome with inflight refueling probe
R48046—Final production intake
R48047—Final configuration intake (Ubangi lower lip)

Falcon included a vacuum formed F7U-3 canopy in its Set No. 39, U.S. Navy Part 3 but it may not have improved on the shape in the Hobby Craft kit. Squadron subsequently produced one as a separate item, Squadron 9629 but again it is not known whether the shape was corrected; however, it is reportedly clearer and thinner than the kit canopy. Note that Squadron's name has been acquired by a new entity; the canopy is listed in their catalog but as out of stock.

Collect-Aire Models produced the ultimate Hobby Craft correction set.

Its resin parts replaced everything from the engine intakes forward. Also included was an accurate, but very thin vacuum formed canopy. Cast metal parts were provided for the cockpit detail and to replace the landing gear, except for the wheels. The decals allowed for the unique markings of VX-4 F7U-3M, a VA-212 F7U-3M, a VF-124 F7U-3M(129963?), and a VA-? (tailcode T) F7U-3M (129559?). One version of the kit and the Collect-Aire conversion is described in detail here: http://www.olddogsplanes.com/f7u.htm 

Resin

Fisher Model & Pattern 1/32 F7U-3M (#3209): Unfortunately not only out of production but the masters were destroyed in a fire since a complete, detailed, and accurate masterpiece can be created from the contents with no aftermarket corrections required.

Paul Fisher

In addition to exterior detail, the kit features inlet ducts leading to engine compressor faces and full-length afterburners. Brass main landing gear struts provide the strength necessary to support the weight of the resin wings and fuselage. All the control surfaces and the sliding canopy are positionable. There's a review with pictures by Mike Williams HERE.

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):

Modex Number

 This is a work in progress but I'm pretty sure of the basics...

The number on the side of the nose of U.S. Navy carrier-based airplanes is often referred to as the modex number (I don’t know of a USAF equivalent). In fact, strictly speaking, it is only one element of the modex number and is in fact, more accurately the “Unit Aircraft Numeral” [MIL-I-18464 (Aer)] or more colloquially, side number.

The "NH" on the vertical fin of this F3H-2N in 1960 is the Unit Identifier or tail code (for posts discussing tail codes, click HERE and HERE)  and the number under it is the last four digits of the Bureau Number, also known as a call number. Note that some units that were only assigned a few of a particular type of aircraft typically used the last three digits (occasionally four in the event of a duplication of the first three) of the BuNo for a side number on the nose.

The term modex apparently didn't exist until the early 1960s, perhaps coincidental with the introduction of the Grumman E-2A with an advanced Airborne Early Warning radar system that used the octal number system for computations like civil ATC's Mode 3 use of a four-digit octal code (4096 possible combinations, no 8s or 9s). It therefore resulted in the elimination of side numbers with the digits 8 and 9 (some arguably knowledgeable experts believe that this was also the result of the introduction of an early maintenance reporting system with a similar limitation). At some point thereafter it became fashionable but incorrect to refer to an aircraft’s side number as the modex number even though it was only part of it and even refer to a side number an aircraft in a picture taken before the early 1960s as a modex.

The Modex number was actually a four-digit code used to identify a specific aircraft by means of its Mode 2 Identification Friend or Foe (IFF) capability. According to Jan Jacobs, a former F-4 and F-14 RIO, it was not resettable by the pilot like the Mode 3 code, which was assigned by civil Air Traffic Control for radar aircraft identification. The first number was peculiar to the Air Wing that the squadron was assigned to and the second, third, and fourth digits were the aircraft’s side number. For example, Jan wrote “Air Wing 2's unique code was "7" so the CAG bird from VF-21 would have a 7200 Mode 2 squawk. The skipper's bird would be 7201. The AWG-10 radar in the F-4J had the capability of reading Mode 2 or 3 squawks by using the APX-76 IFF interrogator system. It was very handy in finding your tanker overhead the ship when there were 2 or more tankers on station. The RIO would set in the tanker's (modex) and the aircraft's distance and azimuth would show up as a double-bar on the radar scope.”

Jan goes on to describe why the side numbers never included the digits 8 or 9:  “The 50's/60's-era IFF systems used 8-bit data systems (Base 8). Digits available were 0 through 7 (a total of 8 bits). In this system, 8 and 9 did not exist as 1-digit numbers. Mode 2 used this system so no aircraft that were in a tactical air wing could use 8 or 9 in their (side numbers) because Mode 2 did not support it. You'll see RAG aircraft and other Navy aircraft with 8 and 9 in their side numbers, but they were not in a tactical air wing.”

Presumably the limitation of the first digit to 8 numbers (if 0 is included) was not a problem since there were never more than a few air groups flying in one geographical area.

There is one somewhat cryptic modex statement in the subsequent  Paint Schemes and Exterior Markings document, MIL-STD-2161A dated 1 May 1993: “MODEX numbers applied to aircraft with the tactical paint scheme shall be FED-STD-595, color number 36081…”. There is no definition of “MODEX number” in that Standard Practice document but there might be in subsequent revisions. More relevant and not inconsistent with this statement, assuming that it only applies to the tail code as well as the side number, is this Call Sign Requirements statement in NATOPS General Flight and Operating Instructions dated 23 November 2009 (it may not be current): Call sign selection for cross-country flights shall be made in accordance with DoD FLIPS. It is strongly recommended that squadron modex (NJ213, DB214) be used in flight planning. If the use of tactical/squadron call signs is necessary, call signs shall be the approved JANAP 119 call sign for the unit concerned. Abbreviations or contractions of these call signs in not authorized.

n.b. I had thought that the typical call-sign used in civil-aviation circumstances was the word Navy or Marine as appropriate followed by the last three or four digits of the Bureau Number.

The practice by some to caption a picture taken after the mid 1960s referring to the combination of the tail code letter(s) and side number (in that order) as a modex would be legitimized by this NATOPS statement but an anachronism for one taken earlier.

 I have yet to find an explanation of the origin of the term Modex, other than it may hark back to the post-war "Mark X" IFF system that could identify a specific aircraft as opposed to simply friend or foe. TACAN systems have a Mode X and Y but those denote two different frequency ranges.

Knowledgeable (e.g. not Wikipedia) comments, additions, and corrections welcome.

F-111B Self Boarding

There were few exceptions to a Navy requirement that carrier-based aircraft be self boarding, i.e. a separate ladder was not required. For more background on this, see:

https://thanlont.blogspot.com/2015/10/carrier-based-airplane-self-boarding.html 

https://thanlont.blogspot.com/2011/09/self-boarding-for-douglas-skyhawk.html

The F-111B was not an exception:

Note that the bottom step is wide enough for both feet. Not obvious in the above illustration is the second step, a peg extended from the forward side of the brace going from the fuselage to the aft end of the bottom step.

 Note the inflight refueling probe location in the illustration above is the original one. Also see https://tailspintopics.blogspot.com/2012/01/f-111b-inflight-refueling-probe.html

The third step, also a hand grip, is a peg that extends out of the fuselage just below the bottom of the crew-escape capsule.

To board from the left side after opening the canopy, it was left foot on the bottom step, right foot on the peg on the brace, and left foot on the peg on the fuselage. It would appear that the next move, getting the right-hand leg over the canopy sill, could be challenging for a short person.

The door that housed the bottom step was a little wider at its aft end and a little shorter than the nose landing gear door and centered slightly aft (the aft end of the "ladder" door is located forward of the top of the aft stripe on the landing gear door) along it.

Self-boarding was utilized during the at-sea trials.

According to Jim Rotramel, my F-111 subject-matter expert, most USAF F-111s did not have the retractable "ladder" door: "The only thing common to both variants was the retractable peg in your fourth pic. It served as an anchor for our boarding ladder, fitting into one of two slots, depending on which side the ladder was being used on. It was ‘interesting' to go to a base that didn’t have our boarding ladders, mostly they resorted to step-ladders."

Jim Rotramel

However, it appears that the F-111As were initially equipped with the ladders but they were subsequently removed and follow-on USAF F-111s were delivered without ladders except for the FB-111A. Bill Spidle provided this front view of one at Offult AFB taken by George Cockle on 14 December 1980. Note the angle of the "ladder" door (it was attached by goose-neck hinges on a tangent to the local cross section of the fuselage, which was identical to the F-111B's for the length of the nose landing gear door). What appears to be a widening of the door as it gets closer to the fuselage is actually the inboard side of the brace behind it.

And this FB-111A boarding ladder from the side:

Sword 1/72 F8U-1P/RF-8 Photo Crusader

22 March 2024: As noted in the original post, an early F8U-1P would require a Vought ejection seat and different wheel hubs than provided in the F8U-1P/RF-8A kit. Modification of the kit seat headrest would probably suffice for the former but exquisite 3D-printed replacement wheels are now available for the latter from Jonathan Smith.

See https://www.ebay.com/itm/186335298796.

Note that the openings in the nose wheel hub should line up.

Smith's main landing gear inboard main landing gear hubs do not include the disc-brake caliper assemblies that are located on the bottom of the landing gear strut but these are easily added.

They are provided on the kit wheels and correctly pictorially oriented if you're paying attention to the instructions:

22 January 2024: This is a work in progress. I'm still making additions and corrections. Please don't hesitate to inform me at tommythomason@sbcglobal of any you have.

This post has benefited significantly from input from Ed Barthelmes and Bill Spidle, who I consider to be Crusader subject-matter experts. For more on this iconic carrier-based airplane, I recommend you add Ed's F-8 Crusader Walk Around Number 38 from squadron/signal publications and Bill's Vought F-8 Crusader from Specialty Press to your library.

Finally, a 1/72 kit of the photo-reconnaissance F8U/F-8 Crusader! And the first impression before building it is excellent (Sword was also provided with pretty good Vought drawings of it). This is Sword's test assembly as an RF-8G"+":

 

To answer the two most frequently asked questions: there is no option to raise the wing and while some of the detail parts like the nose landing gear resemble that of the Academy F-8E/F-8E(FN), F-8J kit (Tom Weinel's preference: see https://superheatmemorial.blogspot.com/2018/12/172nd-f-8-kit-review.html), it is also clearly different in most particulars. One small flaw that Tom noted in most F8U kits (Heller got it right) that Sword also included: there is no fairing or bulge on the upper wing surface at the wing fold joint on any Crusader.

Pictures of the sprues and decals are here: https://aeroscale.net/news/crusader-box-contents. Note that there is no difference in the kits with respect to the plastic, resin, or even instructions. The only difference is the decal sheet. Additional markings will be forthcoming from Caracal Models. Also, don't lose track of the small rectangular tan piece of paper in the box. Barely perceptible on it are the masks for the canopy, windscreen, camera ports, and the view-finder window.

You may wonder, as I did, about the raised rounded triangles on the top of the inboard leading edge slat;

Bill Spidle informed me that these were associated with the F-8L wing which added pylons, one on each side, to F-8B wings. They were located at the hinges of the leading edge flaps and increased the fatigue life of the wing. After the F-8Ls were retired, their wings still had life remaining to they were utilized for at least some RF-8G upgrades.   They are present on the RF-8G "+" BuNo 146882 on display at the Frontiers of Flight Museum in Dallas, Texas. His photo:

They are clearly not as prominent as the kit's and in any event, are not on the F8U-1P/RF-8A wings.

The F8U-1P prototype (a conversion of F8U-1 BuNo 141363) first flew on 15 December 1955. The last flight of one, an RF-8G"+", was to the National Air and Space Museum on 29 March 1987, over 30 years later. There were numerous detail changes to the configuration over that time. Sword provides most of them in this kit.

There were three basic versions, not counting details like DECM antenna fairings and camera ports:

F8U-1P/RF-8A: The most notable omissions from the kit are that the first F8U-1Ps were delivered with a Vought ejection seat, a nose-wheel hub with spokes, and a fuel vent mast under the left hand side of the aft fuselage. For the seat and nose wheel, see https://tailspintopics.blogspot.com/2009/10/f8u-crusader-variations.html. For more on the landing gear changes, see https://superheatmemorial.blogspot.com/2018/12/f-8-landing-gear.html. The kit only provides a Martin Baker seat that might be either a Mk 5 or a Mk 7. However, in 1/72 scale, these can be distinguished by painting the parachute housing accordingly (see http://thanlont.blogspot.com/2011/02/transition-to-martin-baker-ejection.html). For an introduction to the F8U-1P, click HERE.

RF-8G: 73 RF-8As of the original 144 were remanufactured to be RF-8Gs, including new wings that added a pylon on each side. These were delivered between 1965 and 1970. The most obvious external change was the addition of the ventral fins under the aft fuselage to increase supersonic directional stability (the left fin incorporated the RF-8A's fuel vent mast). For some reason, five USMC RF-8As got the ventral fins with no designation change. The G changes included a beef up the landing gear; the differences might not be readily apparent in 1/72 scale (see the landing gear link above). The tail hook shank went from squarish to round (the kit's looks squarish, i.e. RF-8A).

RF-8G"+": The + is a notation that Tom Weinel added to differentiate it from the G's that were modified to this configuration beginning in 1978. The major external difference was the addition of the cooling scoops on the top of the tail pipe and blocking off one of the small vents on the right side of the fuselage just ahead of the wing. For more on the afterburner differences, see https://superheatmemorial.blogspot.com/2018/12/f8u-engines.html

For more general background, see: https://tailspintopics.blogspot.com/2013/12/photo-gator.html. One comment on it by OldGeezer should be noted when evaluating the usefulness of the following:

From 1975-1977, I was one of the tiny group of engineers responsible for the last 30 or so RF-8Gs at the Naval Air Rework Facility in Norfolk. A lot of things stick in my mind, probably of no interest to anyone these days. You mention the ECM antennas, from memory the last ones I personally saw were Air Frame Changes 598 and 599. I don't think any two of the aircraft that came into our shop ever had identical antenna configurations, and we'd incorporate everything they had missed along with the latest stuff, so theoretically they'd leave our line all with the same equipment. That didn't apply to the cameras though. There were different numbers and locations of windows on the various airplanes, and we couldn't do much about that.

Which DECM antenna configuration you use can only be established by reference to the RF-8 that you are representing.

 The first one on at least a few RF-8A/Gs as early as 1966 is the same as on the Crusader fighter of that era:

It uses part 30. The small circle is a tail light. This was accompanied by a pair of antennas on the bottom of the fuselage between the main landing gear doors that are not provided by the kit.

The second one looks like this:

It uses parts 27, 28, and 30. It appears on Gs in pictures dated 1967 through 1972.

The next one deleted the antenna on the leading edge beginning in 1969. The trailing edge fairing extended farther forward on the fin (the tail light was embedded in the fairing) and there appears to have been two different fairing and antenna configurations. One had multifaceted lumps and appears to have been retained for the remainder of the RF-8's service life:

It resembles kit parts 57/58. I'm not sure when the flare/chaff dispensers were added under the fuselage aft of the main landing gear (they are not provided in the kit, either):

The other was shaped like a bullet and the fairing extended the farthest forward. It may have actually preceded the one described immediately above.

This would be kit parts 65/66.

Finally, an antenna was eventually scabbed onto the right hand underside of the G inlet.

This is kit part 70.

The F8Us did not originally have red anti-collision lights on the top and bottom of the fuselage (they were not a requirement on U.S.civil airplanes before 1957; the military was not required to incorporate them but did). The upper one is provided as a separate clear part. The lower one is molded with the bottom of the camera bay, part CP2, and will have to be removed for the initial F8U-1P configuration.

The photoflash cartridge dispensers, one on each side of the upper fuselage aft of the cockpit, are usually covered by a panel that was removed when required for night missions (for illustrations of previous Navy photo flare dispensers, click HERE).

The F8U-1P/RF-8A camera system:

Above the light detector window was one of two sensors, either a light monitor for day photos or a flash detector for night photos. The scanner window provided a view for the image motion sensor.

The RF-8G camera system was initially identical to the RF-8A's but eventually diverged. Note the removal of the Station 2 windows from the side and bottom of the fuselage and the addition of a prism window (kit part CP9) at Station 2 on the right side of the bottom of the fuselage. A second prism window was sometimes substituted for the Station 4 window on the bottom of the fuselage. Note that this airplane did not have the Doppler antenna or the single large DECM antenna fairing (see next photo for both) between the main landing gear doors in place of the two in this photo.

This is the bottom of a late RF-8G"+", mainly distinguished by the addition of DECM antenna variations (kit parts 25 and 70) and a Doppler antenna (molded with the bottom of the camera bay, part CP2, so it will have to be removed when modeling earlier aircraft configurations):

I'm not sure why the scanner window appears to be missing in this photo.

The presence or absence of the left or right Station 2 windows on Gs and G"+"s is another mystery. The left window is often missing with or without the prism window present on the bottom of the fuselage. However, the right window is sometimes present even though the left window is not.

Build Notes

There are holes on the inside of the fuselage halves that would need to be drilled out if you are adding the ventral strakes, which are mounted at a 45° angle. The kit parts have different part numbers but I don't know yet if they are actually handed.

Note that the wings were mounted with anhedral of 5 degrees and the horizontal stabilizers, dihedral of 5.4 degrees (n.b. the left and right UHTs were not connected):

Because of the length of service of the photo Crusaders (the high-time one was retired with almost 7,500 hours after 28 years and 11 overhauls) and Sword's reliance on close examination of survivors, there are mid-life and late-life detail additions on the kit parts like reinforcing doublers around the main landing gear wells and a small bulge above and below the stabilizer at its attach point to the fuselage that aren't present on the initial F8U-1Ps.

More to come...
