About this Plan

Palla d'oro. Free flight gas model.

Quote: "This one is a 1/2A revision of an Italian model. Its name is "Palla d'Oro" (golden bowl) and it was designed in 1946 by Uberto Travagli of Aviominima in Rome."

Quote (google-translated from the Italian): "A model by Turi Russo. The 1/2A Texaco version of an interesting old timer from the Italian school.

Once I reached retirement age, I resumed my old passion for model aeronautics, which had suffered an almost brief interruption (around the 1950s). Through the old Pippo Musolino, with whom I had maintained occasional contact, including work, I had the fortunate opportunity to meet some friends, younger (not so much), who dedicated themselves to Old Timer modeling. Among these was Uncle Milli (born Carmelo Bruttaniti), who introduced me to his wonderful, well-equipped laboratory and equipped, among other things, with a vast collection of old magazines, drawings, etc. The evening of our first meeting I came home with five or six tables of drawings of old timer models.

The ancient passion for gliders pushed me to be the first to build the MG3, a magnificent glider, designed in 1942 by Giulio Meli (published in n°36 of MODELLISM) and with which I had a lot of satisfaction, despite my little skill of thumbs on the transmitter. But among those drawings, the one that most stimulated my desire to build was a model motorcycle called Palla d'Oro, reproduced in a heliographic copy, from the original (and faded) transparencies of Aviominima. In one corner there was handwritten (and the heliography had reproduced it) the date 1946.

The request for information on that model has been forwarded, for the relevant follow-up, to Giacomo Mauro, another Sicilian OT enthusiast. So I learned that it was a project created by Uberto Travagli, who was the founder of Aviominima SA and who worked for a long time in Rome in Via di San Basilio.

I then saw several other of his projects, always beautiful, which involved the installation of the Atomatic engines he produced with a strange radial connection. Since this type of model was created for an engine with a radial connection, this was the further incentive to make me fall in love with the project. In fact, it seems to me that a sort of violence is being done in modifying the structure of the nose of the models that are adapted for use with the Cox. In this case, no adaptations were needed.

During the winter of 2004, working on the CAD and the scanner for several evenings, I designed all the details and sized the model for the 1/2A Texaco version, reducing the original by 20%. In the following spring-summer (my laboratory is in the mountain house where I move in the summer) I built it.

I had to overcome some difficulties in positioning the servos and receiver inside the fuselage; in fact the line of the model is very streamlined so the available width is minimal. Furthermore, contrary to what the original scale model prescribes, I made the engine fairing from a block of balsa, and I brought the spark plug contacts to a lateral jack. Thus, using a plug, it became easy to connect the battery for starting..."

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
