Improving Hasegawa 1:48 Tomcat – 19 Wings (IV)


Recommended Posts

Oh I hate not finishing models. Even if I cut corners or diverge from the initial ambitious plan I try to finish a kit once started. Although my most ambitious project is a far cry from Your Tomcat.

With such a magnificent build like Yours, I hope You'll not get too distracted from finishing it because of a minor thing such as wheel wells.

I'm keeping my fingers crossed for You!

@Mr. Happy

@Sernak
Thank you all. It is because of your interest that my Hasegawa Tomcat is again on the workbench.

 

@Storm
About the Aires stuff I do agree with you. Every time it is always the same, an exercise in cutting and sanding. Check this thread to see how much I had to work on the Aires cockpit to get a fit. That's why I didn't go for the Aires wheell wells. Nice to know that I am not the only one loosing interest in a build.

 

@A-10 Loader
Thank you for your offer that I decline. Back in the days, I had five Hasegawa Tomcats in my stash: an early A, two A, a B, and a D. As soon as I got the rumor that Tamiya was realesing a new 1:48 Tomcat I sold them all with the only exception of the A now on my workbench.

 

@Gwen phoenix
Thank you very much for your interest. I have to say that 2021 and 2022 weren't good years for me in general, and for my hobby in particular. But now is getting much better and I'm curious to see how far this build will go. Stay tuned.

 

@Thadeus
I know, it is strange, but for me finishing a model is not so important. What is important for me is spending enjoyable time working on that model. And yes, you're rigth, I shouldn't focus so much on the wheel wells.

Improving Hasegawa 1:48 Tomcat – 15
Wings (I)

 

In the end, I shouldn't have forgotten that my goal was to improve this kit, not to build a "perfect" replica. Otherwise, the Tamiya Tomcat 1:48, or the one in 1:32 from the same company, would have been a much better choice. With that in mind, I've just retrieved my Hasegawa Tomcat off the shelf of doom.

 

Let's start from the Hasegawa wings (pic 233).

 

IMG_20230321_141957.jpg

 

Dimensionally, and shapewise, the Hasegawa wings in the "clean" configuration are fine (pic 234).

 

IMG_20230321_142215.jpg

 

Unfortunately, the same is not true about the "dirty" configuration. As David W. Aungst explained twenty years ago on Hyperscale (1), Hasegawa's flaps are too long in their chord (pic 235).

 

IMG_20230321_142331.jpg

 

To increase their accuracy they should be shortened by something like three millimeters. In my opinion, the best way to do it would be cutting away the slice of plastic between the two panel lines running near the leading edge of the flap (pic 236).

 

IMG_20230321_142542.jpg

 

In addition to the inaccurate flaps, each Hasegawa wing is lacking four of the six hinges/actuators that connect the wing to the flap (pic 237).

 

IMG_20230321_143412.jpg

 

Not to mention that these two "hinges/actuators", generously made available by Hasegawa, are ridiculously basic, being nothing more than a strip of plastic. As a result, I strongly suggest anyone who dares to build this kit to go for the "clean" wing configuration.

 

Instead of getting my razor blades and giving to my "neurosurgeon" skills a chance, just to engage soon after into a scratchbuilding effort aimed at duplicating the six hinges/actuators for each wing, my lazy solution was to take advantage of my friend Alberto Borzellino offer and to discard the Hasegawa wings altogether for the AMK ones, whose flaps are of the rigth dimensions out of the box, not to mention the level of detail shown by the AMK hinges/actuators. By the way, AMK is giving not two hinge/actuators but all twelve of them... (pics 238, 239).

 

IMG_20230321_143456.jpg

 

IMG_20230321_150209.jpg

 

Pic 240 shows the AMK on top of the Hasegawa wing.

 

IMG_20230321_150653.jpg

 

Dimensionally they are quite much the same. The most important difference is a step running all along the leading edge area. A step rightly missing on the AMK wing, as you can see on pic 241. Rightly because there is no step there on a Grumman Tomcat wing.

 

IMG_20230321_150857.jpg

 

About the AMK wings, my only real criticism concerns the heavily engraved panels, but it is an easy fix (pic 242).

 

IMG-20230321-180923.jpg

 

By the way, the dimensions of the AMK flaps are very, but very, close to the dimensions of the flaps of that Tamiya Tomcat famous for being the most accurate replica of this aircraft released so far.

 

So, the problem now is how to get the AMK wings mating the Hasegawa fuselage.

Improving Hasegawa 1:48 Tomcat – 16
Wings (II)

 

Mating the AMK wings with the Hasegawa fuselages turned out to be much easier than I thought. Clearly, these two kits have a lot more in common than it seems at first glance.

 

In my opinion, the best strategy to insert the AMK wings into the Hasegawa fuselage is to adapt AMK central spar, part V3 (pic 243 and 244), to the Hasegawa upper fuselage, part A7 (pic 245).

 

IMG-20230322-225806.jpg

 

IMG-20230322-225828.jpg

 

IMG-20230322-230033.jpg

 

To this exent, only three quite simple steps were required: The first was to cut off the two pins on part AMK V3; the second was to increase the diameter of the two holes on the part AMK V3; The third was to shorten the distance between the two holes removing a slice of plastic from the middle of part AMK V3.

 

Pic 246 shows the cutter used to remove the pins from AMK V3, the mitre box and the saw used to cut AMK V3 in two halves, and the drill bit used to increase the diameter of the AMK V3 holes to the needed five millimeters (pic 247).

 

IMG-20230323-015537.jpg

 

IMG-20230323-020223.jpg

 

Pic 248 and 249 show the original and the enlarged hole (apologies for the low quality pics).

 

IMG-20230322-231924.jpg

 

IMG-20230322-232010.jpg

 

After cutting the part AMK V3 part in two (pic 250, 251), I kept removing a little of plastic from both halves until they were barely touching each other (pic 252).

 

IMG-20230322-232105.jpg

 

IMG-20230322-232139.jpg

 

IMG-20230322-232229.jpg

 

At this point, using some Evergreen stripe to give the bond greater strength, I glued together the two part AMK V3 halves (pic 253 and 254).

 

IMG-20230322-232347.jpg

 

IMG-20230322-232411.jpg

 

In the following pics (255, 256, and 257) you can see part AMK V3 inserted into the AMK wings and then all this assembly inserted  into the Hasegawa fuselage. Any feedback is very welcome.

Improving Hasegawa 1:48 Tomcat – 17
Wings (III)

 

When it comes to the wings I have to say that the AMK instructions are somewhat confusing, drawings are relatively small and very "crowded". However, before I venture into actually building the wing, there are a couple of things I'd like to figure out with your help.

 

The first is the angle of the wing spoilers when they are deployed while the flaps are extended. According to AMK they are almost vertical to the wing, but I think that is wrong for a plane sitting on the ground.

 

IMG-20230325-224049.png

 

And then I have no idea about about how painting of part A7 and B7 (pic 259). The best pic of this area I saw is on pag. 31 of the Daco book, but it is far from being useful for detail painting.

@GW8345

I have another question for you: What about the flap actuators? Red or natural metal?

Improving Hasegawa 1:48 Tomcat - 18: Undercarriage Legs, Wheels, Seats, and Canopy (II)

 

Sorry for the bad quality of the following photos.

 

Maybe I'm wrong, but I don't think possible that the F-14 undercarriage legs are as angled back as in the Hasegawa offering. Something must be wrong (see pic 260).

 

IMG-20230420-230736.jpg

 

Maybe the main legs are too short or maybe parts F78 and F79 are too long. I don't know. However, this project has already burned me out so much that honestly I haven't even tried to figure out which of these two hypotheses is correct. So, I opted for a shortcut: I did another hole a little further in which insterting the pin of piece C in order to get the undercarriage leg slightly more vertical (see pic 261).

Any feedback is very welcome.

Ciao Lucio,

Your shortcut happens to be exactly the option I recall someone had resorted to in order to fix this issue with the main landing gear legs in the Hasegawa kit.

I've got the G-Factor brass set for my build, but I'm quite sure it's exactly the same size as the Hasegawa offering.

Looking forward to your progress.

Cheers bambino.

 

Gwen

 

PS: I'm still trying to find the build thread where a modeller sorted the issue with the lenght on the MLG leg in the Hasegawa kit.

Perhaps some other members on here remember about that fix?

@Gwen,

Thank you again for your attention.

Yes, the G-Brass legs are copies of the original ones but much stronger, and that is really good !

With some plain plasticard I hided the two original holes making the side bulkhead of the main legs whells more interesting. Well, it's all "gizmology", no accuracy here. Soon after, I began the tedious job of reproducing that tangle of tubes and cables characteristic of the undercarriage wheels only to find out that I really no longer have the needed stamina... so I stopped quite early, finding comfort in the thought that not much will be visible when the model is finished (see pics 263-267).

IMG-20230425-214257.jpg

 

As a consequence of my changes, parts F23 and F24 became too short but some very short pieces of the smallest Evergreen rod came to the rescue (pics 268-269).

And pics 270 and 271 show a dry fit:

Hi bambino,

The main landing gear wells are looking busy enough, I'd say. In the end, as you've said it yourself, not much of it will be visible after the kit sits on her legs anyway.

Had better keep your stamina for working on details that will be a lot more visible than that, such as the bang seats, windshield and canopy.

After that, you're done with the detailing and/or correcting, aren't you, Lucio?

 

Any fellow modellers reading this: Please, anyone of you who have built the AMK 1/48 Tomcat D kit with her wings swept back, and still have part V3 to part with, let me buy it from you. Drop me a PM or just say it out loud on here. Thanks chaps.

Cheers,

 

Gwen 

 

PS: Bummer, I'm still not able to find that build thread where the length on the MLG scissors in the Hasegawa Tomcat kit was sorted out.

I have two questions regarding the F-14 wings.


First: I don't know what to do with the wing spoilers. According to this reference:
http://www.anft.net/f-14/f14-detail-wingcontrol.htm
I have three options: 1) down, 2) up 5°, 3) up 15°.
Which of these three possibilities is the most congruous with the following configuration: canopy open, only rear step open, ladder closed, tail airbrake open, and wings in the "dirty" configuration.


Second: According the same source, in a landing configuration slats should be down at 17°. Now that I am working on the AMK wings, I can't tell if the AMK slats are really dropping at 17°. Anybody out there in the know ?

Lucio... firstly you are a MAD MAN... MAD MAN... I tell you... but HUGE respect.  The work you are doing here and sharing with us is nothing short of encyclopedic and extremely welcome.  But damn, where were you when I started building mine a few years ago... I'm finishing her off now.  This reference would have been truly invaluable.

 

Wonderful stuff!

If I may;

 

For the configuration you are doing (canopy open, only rear step open, ladder closed, tail airbrake open, and wings in the "dirty" configuration) I would recommend the flaps/slats in the landing configuration and the spoilers at 55 degrees. This is the configuration the aircraft would be in for maintenance (phase) and getting a wash job.

 

As to the AMK kit's slats being at 17 degrees, sorry, can't help with that, don't have the kit.

Thank you for your prompt answer.

 

Nothing set in stone yet but of all early F-14A here is where I am going to:

https://www.airfighters.com/photo/184737/M/USA-Navy/Grumman-F-14A-Tomcat/161135/

 

Not perfectly my planned configuration, canopy is closed instead of open and I can't tell about the airbrake, but it's almost there. Can't tell either if the spoilers are shut flat or up the 5 or 15 degrees, surely they aren't at 55, that's why I was asking.

 

I trust you that the 55 would be the most accurate, but - honestly - I don't like it. Barring 55°, what would be your pick: flat, 5°, 15°

 

Thank you again, Lucio

IIRC, the 5 and 15 degree only happened in flight or with electrical/hydraulic power applied to the aircraft so to do it on deck without the engines running or power/hydrualic power applied would not be accurate. In order to get the spoilers to "pop" and stay you had to pull the C/B so they were either open 55 degrees or closed when there was no electrical/hydraulic power on the plane.

 

Given a choice, I would go with either keep them closed or have them open to 55 degrees.

Another update, a short one. This time it is about the undercarriage doors. In my opinion, out of the box they are too bare (pic 272).

 

IMG-20230520-215602.jpg

 

Just to make them looking a little more interesting, first I thinned them somewhat (pic 273).

 

IMG-20230520-220037.jpg

 

Then, I enhanced their appearance with some 10X20 Evergreen stripes (pic 274).

 

IMG-20230521-002331.jpg

 

Again, I was very, very, but very, freely inspired by the real stuff...

@Gwen Phoenix

I am doing well, thank you, and I am happy to read that you are getting part V3.

Your question about replacing pats J5 and J11 is a very good one...

______________________________

 

 

Improving Hasegawa 1:48 Tomcat – 19 Wings (IV)

 

... the best solution would have been to create a resin copy of parts J5 and J11 but I've never had an AMK Tomcat. The AMK wings that I'm using in this project are leftovers from a kit already assembled with the wings at maximum sweep by my friend Alberto Borzellino, and I haven't found the courage to ask somebody else to cut these two parts from the sprues and lend them to me for the necessary time to make the silicone moulds.

 

In the end, I went very old school and resorted to my much loved Evergreen plasticard. After having firmly glued the plasticard in place, using the Hasegawa wings as a template, I shaped the plasticard bits with my no less beloved sanding sticks, as shown in photos 274, 275, 276, and 277.

For what concerns the proper slime ligths, I am planning to go with the Hasegawa decals, but we will see.

 

Another solution that I have been evaluating for a while was to cut off the wingtips of the AMK wings and to replace them with Hasegawa wingtips, but I discarded it because it was risky.

Nice detail on the wheel well covers. Good call on filling the slime lights with plasticard. I guess You could fill them with some clear plastic, and then try to paint them with diluted green colour. But this way You'd get two different types of slime lights, one on the wingtips, other on the entire fuselage and tails. I guess decals or just paint is a better way.
