Hasegawa 1/48 SH-3H Sea King (Apollo Recovery SH-3D Conversion): Part 4

With the main bodywork of the aircraft completed last time, I finally got her standing on her undercarriage, in the form a set of ResKit resin wheels—slightly more detailed than the kit parts, with a nice open fork for the rear wheel.

The kit parts for the undercarriage legs need a very slight modification. They come as an interchangeable pair, but they were in fact slightly asymmetrical, with tie-down lugs only on the outside of each leg. A little work with a scalpel removed the unrealistic inner lugs, and then I just needed to remember to put the legs on the appropriate side of the aircraft.

Then it was time for the rotors. I painted the red and white warning stripes on the tail rotor, and the yellow tips to the main rotor, but resorted to printing up my own decals for the yellow stripes on the rotor blades.

I wanted to model the main rotor folded, because I’m aiming for the appearance of this helicopter at a very specific moment in its career—at about 07:55 GMT on 24 July 1969, just after landing on the deck of the USS Hornet with the Apollo 11 astronauts on board, while being towed to the elevator to descend into the hangar bay.

With the rotors test-fitted, I removed them while I added all the fiddly surface detail needed to make the helicopter come alive. I added a length of cable and a sling to the kit’s winch, so that I could reproduce the partially stowed position in the view above.

I added my scratch built camera mounts and the SARAH yagi antennae, which had been languishing in a pot for safe-keeping during the whole build process. I belatedly realized that I had planned to place the forward camera in the wrong place on the forward weapons mount points. I’d aimed to place it on the forward position of these two points, tucked under the horizontal sponson support. But a late find of an underside view of this aircraft (during the Apollo 10 recovery) convinced be that the camera needs to be on the aft position, behind the sponson support, where it’s clearly visible in the photo. That meant a little work with a scalpel and some touch-up paint, and the rerouting of the forward camera cable-run in its last few millimetres, but it was fairly painlessly accomplished.

And I put together a rotor retainer sling from styrene and painted paper, to restrain the two outermost folded rotors. You can see it in the image above, and there’s additional detail visible in hangar-bay views like this one:

And I rigged the radio antennae on both sides of the fuselage, placing the kit mounting pylons in locations gleaned from the aircraft photographs, and then running stretched sprue between them to reproduce the run of the aerial wire. The underside view I linked to earlier was particularly useful in judging the length of the pylons, and from peering at various other photographs, this is what I came up with:

Open dots are mounting pylons, closed dots are points where wires join (on the starboard side, a short length of wire appears to come out of the fuselage and link to a simple span of wire between two end pylons.)

By the time I was placing cockpit mirrors and pitot tubes, I was beginning to run out of places to hold the model.

Here’s the final result:

10 thoughts on “Hasegawa 1/48 SH-3H Sea King (Apollo Recovery SH-3D Conversion): Part 4”

  1. Hey Barry. Thanks for the kind words. I’m impressed you’ve stuck with my witterings for so long!
    Keep safe.

  2. Excelente trabajo de investigación y de replanteo de la maqueta. Saludos y Felicitaciones un apasionado del Sea King. Adrian Moltoni – ARGENTINA

  3. As a former flightdeck sailor I can’t look at there pictures without hearing them in my mind. The whole first launch of the day starting cycle is still strikingly vivid in my mind.
    Oddly enough doc, I’ve see more Sea Kings taken out of commission by wrenches dropped from high on the island than by going into the drink. 5 vs 2 by my count. And this is despite of all the highly intelligent individuals who make up the safety protocols required for such work. A smaller falling wrench will crack the rotor blade if nothing else. (Which, by the way, are hollow and pressurized with nitrogen so as to detect cracks instantly.) I’ve seen larger wrenches go all the way through and out the belly.
    It isn’t accidental that the more inexpensive aircraft, Sea Kings and Hawkeyes, are parked next to it.

    1. The little BIM gauges on the rotor blades, which change colour if the nitrogen pressure inside the blade drops, remind me of a very basic mechanical low-pressure warning we used to have on an ancient anaesthetic machine I once used. But I can’t for the life of me place it, at present. Same principle, I think–the pressure holds the red indicator stripes out of sight, but if the pressure drops they pop into view.

  4. Brilliant research, engineering, and finishing. You should be very proud of your superb replica.

    I have been studying the Sea King recently, but my basic kits are somewhat smaller – the Tamiya 1/100 version from 1971 and the new AFV Club kit from Taiwan in 1/144. Both come with markings for “Helicopter 66”, but they will need work. 1/100 is an orphan scale; finding aftermarket items for 1/100-scale kits is an exercise in futility.

    At any rate, your magnificent job on “Helicopter 66” is positively inspirational. Thank you for posting it all.

    1. Thanks for the kind words. And respect for your small-scale aircraft modelling. I struggle with 1/72 these days!

  5. One last comment, Dr. Grant, on Sea Kings.

    There is a safety issue with helicopter rescues at sea that most people don’t know about until AFTER you get into the fleet.

    When one finds oneself inadvertently swimming in the middle of the ocean, with its inherent demotion on the food chain, a lot of folks are known to become quite “anxious”.

    But it’s very, very important, despite one’s fears, to let the helo dip its rescue harness and/or basket into the ocean first, BEFORE you touch it!

    This is due to the fact that the rotors spinning through the air produce a massive charge of static electricity, especially on less humid days.

    I’ve known two people who didn’t know that little tidbit of information and had their abilities to tread water severely impacted.

    (That’s where I learned that Navy rescue swimmers have rescue techniques for drowning victims that can be employed…in the water!)
