Hasegawa F-4 Eggplane


I always liked Hasegawa's eggplanes, but never bought one when they were first issued. When they were reissued in 2008, I obtained an F-4. These eggplanes are often advertised as a good cure for Advanced Modelers Syndrome (AMS), but I guess I got a placebo. Hence I modified it quite extensively to suit my taste.



AMS plans

Although I picked the F-4 because I liked it best in the jet eggplane series, I was not completely happy with the Phantom's shape. The inlets are really too big, and the same goes for the nozzles. They are a caricature of a caricature! The F-15 model suffers this problem even worse. I took a side view photo and studied the possibilities for modification in CorelDraw. This looked promising, so I decided to go for a fairly big plastic surgery. Another problem is the crew: there's no backseater. Having a full crew required making a copy of the pilot figure, since there are no spare eggplane pilots in my spares box. Regarding the markings, I wanted my silly eggplane to look as bad and macho as possible. Browsing through an F-4 book I found what I was looking for: the markings of Marines squadron VMFA-531, with a big skull on the tail. It also meant that the F-4E would have to be modified to make it resemble an F-4N somewhat.



Construction

I started with the pilot, who was molded integrally with the fuselage halves. I removed him using various scribing devices and saws. Next the cockpit opening was cleaned up. The pilot was assembled, and the rather soft detailing was improved until I had a reasonable pilot's head. The upper torso was later cut away because it prevented a more active posing of the heads. A copy was cast to obtain a backseater. A simple cockpit tub would be added later.
The inlet height was modified by removing a piece of around 4 mm from the inlet side, and moving the lower part upwards. The sawcut is visible as a white putty line halfway up the inlet side and on the rear of the fuselage. The front edge of the lower and upper intake no longer matches, and it was later restored with a piece of plastic strip.
The lower fuselage was roughly reshaped with Milliput, extending the egg-shaped part until it met the inlets again. The gun pod under the nose was also cut off, and the hole closed with plastic card. The radome is quite big actually, and I think it better represents the big-nose early Phantoms than the F-4E/F/G. The F-4N's infrared sensor will be added later.
More difficult was the operation to make smaller nozzles fit the model. I had decided on using the 17 mm diameter nozzles from an eggplane SR-71, replacing the 20 mm diameter F-4 nozzles. This meant the rear fuselage was too wide now. It required a three sawcuts and one partial cut (serving as a hinge) to allow bending of the inlet duct. The fuselage side was made straight with Milliput, removing the strange pinched shape that Hasegawa came up with.
This rear view shows the modification one more time. Note the change of the upper fuselage meeting the nozzle area. Some scraping was required there.
Just to show how much smaller the SR-71 nozzles are compared to the original nozzles, here's a rear view with both nozzles attached.
The preliminary result of the plastic surgery is best judged in a side view, after base-coating the model with a light gray paint to hide the worst scars. The inlet modification was a lot of work, but for me it was worth it. The smaller SR-71 nozzles are also test-fitted. They were fairly long, and gave the impression of long F-4E/F/G nozzles instead of the short F-4N nozzles. Therefore one millimeter was cut from the base.
On ARC I spotted Phil Silverback's Phantom eggplane with engines visible through the inlets, but I couldn't see whether the model had inlet ducts extending to the engine face. It looked really good, and when I thought about it, it wasn't too difficult. Just put in a piece of plastic card with a circular opening (as shown in the photo), and create a rough inlet duct from plastic card (not shown), plaster the rough duct with a lot of Milliput, and and lastly sculpt a smooth duct with a wet brush handle, using the inlet opening and the circular holes as guides. The compressor faces are from an Airfix S-3 Viking from the scrap box. The look a bit turbo-fanish but they fit well with the distorted eggplane concept I think.
And here's the end result, after the Milliput sculpting and painting of the inlets. It was fairly easy and I'm sure I will use the technique again on a 'serious' model.
I think it was again on ARC that I saw an eggplane (F-16 I believe) with a deep exhaust. That made me realise that there was a big mismatch between the deep inlets and the shallow exhausts of my model. Therefore I decided at a late stage to deepen the exhausts. I couldn't find a piece of tube of the right diameter, so I did the next best thing. The technique was identical to that of the inlets: I glued a piece of plastic card with a hole where the turbine face would go, and filled the area between the card and the nozzle with Milliput, shaped with a wet tool. I also removed the tail hook, since the halves didn't line up nicely. You can also see the amounts of Milliput used in the construction of this model :-)
So far I hadn't given much thought about how to display this model, but a 'flying' model seemed like the best idea. I wanted to install a Matchbox stand-type ball joint, but didn't have one at the time, so I prepared the model by installing a short piece of brass tube. In the end my modeling friend Eric supplied me with two ball-joints, one of clear polystyrene and one of black polypropylene.
Using the extra cast pilot head/helmet, I could figure out how to place the crew in the cockpit. Space was very tight, and they are like in a bobsled :-) I posed the navigator looking to the right and the pilot looking to the left. Initially I had them turned their heads 45 degrees, but that made a 'Where did that MiG go?!?' kind of impression, so I reduced the angles to roughly 20 degrees, creating just a bit of variation in the cockpit. Later I sculpted new upper torsos using Milliput. Having a neck between the torso and the head/helmet also improved the looks I think.
The wings were attached, and another round of sanding and filling was started. I'm not sure how the wings fit on an unmodified Egg Phantom, but I had to do quite some work to make things fit seamlessly, especially on the lower side. But with the end in sight, the job was done without complaining too much.

Last task before painting was some work on the panel lines. I removed all of the raised panel lines on the wings and vertical tail, moved the radome panel line 1 mm aft to increase the radome size slightly, and scribed lines to define the bare metal areas around the exhausts.


Colors and markings

I made a side view photo and overlaid it with the planned markings in CorelDraw. I started with the VMFA-531 markings, that I redrew as vector over a bitmap picture. The rest of the markings were easy, just Navy style lettering and a star & bars. The white radome may not be typical of an F-4N, but I liked it better. I'll probably go for black-painted canopy framing, although I haven't seen it yet in VMFA-531 photos. Seen here is the first version of the proposed markings.

I got a note from ARC member 'Grey Ghost 531', who was in VMFA-531 during the F-4N period. He suggested changing the tail color from black to insignia blue, and making the "N" and the "K" on the tail touch. Both corrections were made to the decal artwork. I also learned that the NK code was used while VMFA-531 was at the USS Coral Sea from the spring of 1979 until late summer of 1980. He confirmed that VMFA-531 F-4Ns always had gull gray canopy framing, and pointed out that an F-4N should include a fairing under the radome and DECM fairings on the intakes. Most likely I will add these details. Shown here is the second version of the proposed markings. I also drew in the canopy frame to study the effect of black canopy framing. I'm not convinced yet.. Also I enlarged the radome in the drawing, and reduced the warning triangle ahead of the intake.

More corrections on the tail artwork. 'Grey Ghost 531' remembered: "When the aircraft came in from depot maintenance the tail was over all gray. The paint shop would mask off the skull and "NK" and then shoot the insignia blue. They then had stencils for the eyes and the gap between the cranium and the jaw which were sprayed black and then another stencil for the teeth which where sprayed white." A big problem is that I can't print gull gray nor insignia blue with an Alps, so maybe I will have to use incorrect markings. In this version I reduced the size of the stars & bars.

Decals for the pilot visor covers are also planned. One problem is that the visor cover can't be black, since the visor itself is black too. Therefore copying the skull tail decal was not possible, or I have to reverse the colors.
