VB-83 Curtiss SB2C-4 Helldiver

The Helldiver was ordered into large-scale production in 1940, the prototype making its first flight on 18 December of that year. SB2Cs went into action for the first time on 11 November 1943 in a heavy raid on the major Japanese base of Rabaul, flying from the new Essex Class carrier Bunker Hill.

This large, heavy, impressive and powerful dive-bomber was intended as an improvement on the SBD Dauntless, which it was to replace. However, during the SB2C's development it became apparent that there were serious problems with its design. Combat experience, especially at the Battle of the Philippine Sea, revealed that the Dauntless was in fact the superior aircraft. The Helldiver's handling was poor - in particular it had unsatisfactory low-speed stability, and dangerously poor stalling characteristics.  However, it was at this stage impossible to reverse the changeover to the Helldiver, and the Philippine Sea battle was the SBD's last major action as a carrier aircraft.

The -4 version finally produced an aircraft worthy of the earlier promise.  Dive stability had been greatly improved by further perforating the dive flaps, bugs in the (still) overly complex hydraulic system had been worked out, and it's crews were beginning to have faith in their mount.  At the same time however, evolving carrier operational tactics were reducing (and in some cases even eliminating) carrier bomber squadron strengths.

Despite its initial lackluster showing - and its inherent defects - the SB2C served as the sole shipborne dive-bomber of the US Navy from late 1944 until the end of the war, eventually inflicting more damage on enemy shipping and installations that its predecessor , the SBD Dauntless.

Construction

Construction is broadly the same as for the previous models.  Built basically OOB with some minor scratch built additions to the cockpit. 

Notable differences include the use of the included PE parts and the level of quality of the kit far exceeded my expectations.  To my mind this kit is at least of the same quality as Tamigawa and AM.  I did use a little filler I'm sure, but I honestly don't remember where.  I was given a heads up regarding the wing roots, but with care I found that they worked well for me. 

The interior was painted with Gunze Interior Green, which is a slightly darker shade than MM.  I was during this stage that I did make a couple of mistakes however.  I had intended right from the start to display the model with lowered flaps.  However, I failed to cut the supports of the wing and settled with only dropping the PE portion.  Since these photos were taken, I've raised the flaps to the upper position.

 The other error was in not installing the life raft in the rear cockpit until it was too late to make it fit.  I just settled for that as I didn't realize this until the model was painted.  Initial construction finished with masking the canopy with a mixture of Tamiya tape and Parafilm M.


 

Paint & Decals

Essex's VF-83 Helldivers were -4's painted in the Tri Colour scheme, with a couple of replacement aircraft joining in late July painted in GSB.  Again, I had a particular plane in mind which appears on page 68 of Barret Tillman's "Helldiver Units of WW2".  Aeromaster makes a decal sheet for this particular aircraft, which I had bought and intended to use.

I began with the white underside, using the Badger 200, and gave it several coats of MM Acrylic Insignia White.  I also painted the prop cowl white, though it could also have been Intermediate Blue, with no photo available of this particular plane I just made a judgment call based on my feeling the white looked better! When this was cured, I switched to my Badger 155 double action and applied the Intermediate Blue, this time MM Enamel, freehand.  I prefer enamels when spraying freehand as I find I get greater control and a finer demarcation line between colours.  When the intermediate blue was dry, I applied the dark blue (FS35042), again using MM enamel sprayed through the Badger 155.  There were some inevitable over sprays and mistakes to correct, but overall this attempt at the tri colour scheme went well for me and I was pleased with the result.  Once the paint was fully cured, I think I left it alone to cure for at least 3 days, I applied the gloss coat, again using Metalizer Sealer.  

 

 

Decaling for me always begins with the national insignia.  This one was no exception and I used the Aeromaster supplied ones.  They went down well, I used Micro Sol only and experienced no problems with wrinkling or silvering.  The trickiest part of the decaling process was using the vertical stabilizer decals.  They were slightly oversize and needed some persuasion to melt down into the rudder hinge area and over the rudder tab mechanism.  I eventually cut the decals to help them get over these surface irregularities and touched up with paint when they were dry.  All the other decals went down with little trouble.  I applied very few stencils as the photo of the subject aircraft showed very few to be present, though I am fully aware of other shots of (newer?) aircraft covered with all the stencils applied at the production plant.  The only other thing worth mentioning about the decaling process was that I had to paint the G-Symbol on the wings as Aeromaster had not seen fit to included them in the sheet.  This was accomplished with little trouble and finally it was ready for the sealing coat and weathering.

 

 

As usual, I sealed with a couple of coats of heavily diluted light gray to fade down the paintwork, again making sure to fade down the areas in direct sunlight with the wings folded a little more.  Dullcoat was next, bringing the sheen down to a semi-gloss finish.  When I next picked up the model a couple of days later I discovered, quite by accident, a technique for weathering that looks (to me) quite realistic.  In holding the kit by the wings, I noticed that my skin oils would vary the level of sheen on the finish and by literally rubbing my thumb and fingers over different areas of the plane I could vary the reflective qualities quite dramatically, to show heavily trafficked areas on the wings for example.  This is not so visible in the photographs, but give it a try, if you don't like the result, it's easy to fix.


 

Weathering and Conclusion

As is normal for me, weathering is done with pastels.  I applied a few paint chips around the gun hatches on the wings and the engine cowls, but kept it to a minimum.  Using various shades of pastel I highlighted and scuffed areas of the plane according to traffic and exposure to the elements.  I added all the small and breakable bits, used stretched sprue for the antenna wire and attached it with white glue. 

I really enjoyed this kit.  It was the first of the four Essex aircraft and it was during its construction I got the idea to complete the Air Group.  I highly recommend it to any but the most inexperienced modeler.
