Canada Day Special: 1/48th Hasegawa CH-124 Sea King (HSS-2B Conversion)

Updated: Jun 29

This kit is still the only Sea King available in 1/48 scale. It was released in 1992, however the model is still holding up well. Hasegawa continues limited-edition releases of these Sea Kings as part of their flagship PT series of kits. I converted this one into a Canadian CH-124 with the help of Belcher Bits conversion sets. Your best starting point for a CH-124 type is actually the RAF releases if you can find one (ideally with the short sponsons and dorsal radar included).

Notable Kit Features:

  • Finely scribed and molded surface details

  • Nicely detailed flight deck

  • Dipping sonar, Sonobuoy launcher and other details (not used on this version)

  • Optional torpedoes on external mounts (not used on this version)

  • Photo-etched grilles

  • Choice of engine intake FOD shields (but not quite the correct one for this version)

  • External winch

  • Main rotor blades molded with a slight 'sag'

  • Main rotors can be positioned in flight-ready or folded/stowed position

Build Inspiration:

Fifty plus years service in the Canadian military... need I say more? Sea Kings have had a long service career with many militaries around the world, as well as in Canada. I had originally bought Gulf War decals to build this kit with however when Canuck Models released this "Anniversary" set I was sold on these markings instead (I may have to build another one.. or two of these kits at some point).

Heads-Up Report:

  • Crew entry door and main cabin door are molded closed

  • Only the main cabin floor and rear bulkhead are present, so any interior detail will have to be added (if desired - and unless you open the side door it won't be seen)

  • CH-124 was 5 blade rotor-head (don't use the 6-blade if provided)

Kit Additions / Modifications:

  • Purchased Belcher Bits Conversion to get short sponsons and dorsal radar (

  • I attached the sponsons to the fuselage using brass rod as there is a bit of a stand-off from the fuselage and I wanted some strength at this point after I broke the kit plastic

  • Used Canuck Model Products CH-124 Seaking "50 Years" decals (although opted to paint on most of the base colour details) - Unfortunately my custom made paint masks ended up peeling off the Yellow / gold as well as black paint in many places so that had to be repaired along the way :0

  • Capped off Left / Right Observation windows under sponson support bar

  • Filled the middle fuel point on kit as CH-124s only had two points per side

  • Closed off two openings in bottom for dipping sonar gear and detector

  • Shortened horizontal stabilizer to 37.5 mm (no support bar used either)

  • Scratch-built engine intake cover as kit versions were not quite correct for RCAF

  • Added additional mount plate just aft of the dorsal radar

  • Add scoop over vent just aft of cockpit on right side

  • Scratch-built IR camera mount on nose

  • Added CPI (Crash Position Indicator) to starboard side just aft of sliding door (from Academy KV-107 kit or from Belcher Bits if you weren't lucky enough to have that kit in your inventory as well)

  • Add rectangular rear view mirrors to both cockpit sides (subsequently broke mine off)

  • Tinted top windows using green magic marker

  • Various kit options omitted and necessary antennas added although I missed some I just noticed ;)

Note: The kit tail is separately molded at the fold point and while Hasegawa doesn't provide the internal bulkheads / details to fold the tail, you could make that happen. The main cabin door is molded closed, however it could be removed and the door frame / interior fabricated... if you wanted to go there.

End Result:

The paint scheme for this aircraft was a challenge, (Metallic gold-yellow over FS 36173 base) however it was such a eye-catcher I had to give it a go. I was pretty happy with the results at the time, despite the errors and omissions along the way, it is a great addition to the display shelf.

The After-Build Report:

This Sea King by Hasegawa is still a recommended kit in my book. It has nice exterior details and the interior details that are likely to be visible are good. The option to display the rotors folded is a major bonus for this 1/48th scale kit, as it makes the kit much more compact on the display shelf. Note: Revell re-released this same plastic in their 04466 SH-3H kit

Completed build #227 - September 2019 using the 1/48th scale Hasegawa #PT2:4200 kit.

Feel free to comment or ask any questions - Keep on building, gain experience, challenge yourself if you like, but try not to stress yourself out over the build - it is suppose to be an enjoyable hobby after all - Cheers

If there existed awards for this, that Canadian CH-124 would win best of show. That is one hell of an eye-catching build!

Thank you Chuck717, That special Anniversary paint job certainly was the inspiration to get my CH-124 Sea King built. It has a highly visible place on the shelf here behind my work desk. I am just finishing off a CH-126 Choctaw in the RCAF Red, Blue, White scheme that may give this build a bit of eye-catching competition - Appreciate the interest - Cheers, David | Fly Past Rush
