Introduction

 

Classic Airframes 1/48 scale S.79 tri-motor Italian bomber is a limited run kit featuring injection molding with finely recessed panel lines, resin cockpit, and additional resin and photoetch details. Although the kit is not for beginners, it is a good choice for those with moderate modeling experience. The end product captures beautifully the unique appearance of Italy's most famous bomber, and makes a great addition to any WWII aircraft enthusiast's collection.

 

 

Construction

 

Construction begins with the cockpit. The resin parts fit perfectly and offer no problems. I wanted to display the dorsal gunner's position open, so I enhanced the interior areas with additional framing made from strips of styrene. At the gun position I added a brass ammunition belt and made a chute for spent cartridges.

 



I encountered an aggravating problem when attaching the small windows just aft of the cockpit (clear parts 2 and 3). In an effort to fit the parts flush with the fuselage I used too much force and caused numerous stress fractures in the clear plastic. I should have done a better job test fitting before trying to install the windows (the holes in the fuselage were far too small). The stress fractures were obvious and very distracting given the prominence of these windows on the model, and no amount of polishing would have corrected the problem. At this point I was tempted to sideline the project for a while. Luckily, Kent Eckhart (aka Boise Kent), came to my rescue and produced two vacuform replacements which fit perfectly and were crystal clear. Thanks Kent!

I decided to open the gunner positions on either side of the fuselage.

Waist guns are not provided in the kit, so I found appropriate parts in my spares box. The mounts were fashioned from pieces of styrene.

Photoetch ammunition belts were also added.

 



Proper attachment of the engine nacelles proved to be another challenge in construction. Unlike manufacturers like Tamiya and Hasegawa, limited run kits like Classic Airframes lack the convenient locating pins and mounts which help with alignment of parts. Achieving the proper alignment for the nacelles proved more challenging than I had expected.

My first mistake was using CA glue to attach the nacelles. I reasoned initially that it would be an advantage to secure the nacelles quickly, rather than relying on slower-acting plastic cement and the possibility that the nacelles would shift in position as the glue dried. However, once the nacelles were attached it became apparent that I had positioned the center nacelle incorrectly - it tilted upward like a pig's snout.
The problem could not be ignored. However, removing the nacelle was problematic, especially since the entire model had already been painted by this stage. I ended up running CA-debonder behind the nacelle and gently twisting and wiggling the cowl until the assembly broke free. Of course, the paint finish on the cowl was ruined and required complete reworking. Luckily the rest of the model, including rigging, remained intact during my assault on the nacelle. Once the cowl was refinished, I decided to reattach it with 5-minute epoxy. This turned out to be a good decision. The epoxy hardened slowly enough to ensure proper positioning, but fast enough that I didn't have to hold the assembly steady for a long period of time while the glue set. In the future I would use 5-minute epoxy from the outset, or use metal rods to guide and anchor the nacelles in position before gluing.

 



The resin exhausts already come partially hollowed, but I decided to drill them out further for added realism. Once the exhausts were glued to the cowls, I used Tamiya putty to fare each exhaust to the cowl ring.

If this is not done the exhausts will sit awkwardly on the cowl, looking rather dysfunctional. Be sure to check your references for the position of the exhausts on the aircraft you are modeling (see step 21 of instructions).

 

 

Painting and Markings

 

The metallic rings on the engine cowls were painted with Alclad II over Tamiya's fine surface primer. The silver rings were made using Alclad II's polished aluminum, whereas the darker cowl ring was a mixture of copper and dark aluminum to give a burnt aluminum appearance.

I painted the camouflage freehand using both Tamiya and Polly Scale acrylics. The underside was painted with Polly Scale Italian light blue-gray. The upper surface colors were based on my own mixtures of Tamiya acrylics. The light sand color is buff (XF-57) with a touch of dark yellow (XF-60), the brownish color is a mixture of red-brown (XF-64) and khaki (XF-49), and the green is olive green (XF-58). These are not mixtures specified by any particular reference. Rather, I was attempting to approximate the colors shown in various color profiles.

 



The camouflage pattern was based loosely on a color profile in Squadron's In Action book, as well as various wartime photographs.

The camouflage and markings represent an aircraft of 253a Squadriglia in the summer of 1940. I used Sky Models decals sheet 48-018 for all markings.

 

 

Photography

 

Images were taken outdoors with a Nikon Coolpix 5400 digital camera set for maximum resolution. The "sharpen edges" tool in Adobe Photoshop was used to restore some of the clarity and crispness lost during image compression.
