Scratch-built 1/72 Caproni Stipa

From the archive (2006). My first ever scratchbuilt model:

“The Flying cannelloni”

We could say that the Caproni Stipa was a gigantic flying Venturi tube. Or a flying hollowed barrel. Or a plane built around emptiness. Whatever way you may like to conceptualize it, you must admit that is a very beautiful thing, if you are so inclined.

In a sudden epiphany I realized that was very unlikely that any manufacturer, no matter how mad or desperate, would ever tackle this plane.
So I decided to go for my first scratch project ever, knowing that once I had my model finished, then perhaps some manufacturer will surely produce a kit of the thing, as Mr. Murphy well knows.
The Internet provided images and a set of plans which I adjusted to 1/72 scale. Patterns were cut and the project started.
A quick trip to the hardware store produced a PVC pipe of 1 inch of ID and somewhat thick walls. I must say that I have now enough supply to make hundreds of Stipas' tubular fuselages.
Then with the trusty Dremmel and the drum sander I started to shape the Venturi-like fuselage.
Shortly after I had managed to cover myself in PVC dust, the part emerged. Holes for the wing spars, landing gear and rigging were measured and drilled. The spare box provided the wheels, seats, instrument panel backing, propeller.
A balsa plug was carved and a "heat and smash" part was produced from plastic sheet for the upper fuselage hump. This was cut open in order to give access to its brave crew. Some structure was added to the side walls, a couple of formers glued and the doors were engraved.
Flying surfaces were made of plastic card, being the wings formed essentially by two -upper and lower- planks, a plastic rod leading edge and a tiny reinforcement with card at the wingtip. I curved the upper plank a tad in order to get a credible airfoil. Tail surfaces were just made of sanded plastic card.
Two plastic rod spars would carry the wings and the engine going through the fuselage.
The plane's engine, a DH Gipsy III, was made, after a couple of failed tentatives, with metal tubes of different shapes, puttied, painted and was located inside the fuselage. It is a little bit like building a clipper inside a bottle, but far easier.
There were apparently two configurations of the same plane, differing in the tail surfaces for what I can tell. The first one had the smaller tail and was probably finished -at least in the photo I found- in an overall metal hue, with some small patches here and there. Now this was tempting, since the decoration on the other version is really complicated, although attractive.
Building proceeded without too much hassle and painting followed, leaving the tail surfaces, landing gear and details off the scene for a while. After priming and sanding I applied the beautiful blue and then cut a few masks on masking tape to cover the "feathers" of the scheme. The light cream color followed, and then the remaining main parts were added.  I printed my own decals. A Pitot tube was glued and the rigging -mono filament- and decaling finished the matter.
This is my first scratch project. It required some little extra work but was fun. The model achieved is quite convincing and in spite of a few blemishes I think it catches the aura of the design.
The Caproni Stipa oozes the magic of an era of glamour. The strange, chubby model looks like a real classic.
