Update 26/04/2018: added article, thanks to Pit.
Update 02/05/2018: added two pages about Ridenti's success with the Duca/ Duchess at the Pensacola SAM Champs in 2000, from Modellismo, thanks to Pit.

User commentsDuca was the name given in an Italian mag after the War. It is, in fact, an American design but the Italian name stuck when Italian modeler Ninetto Ridenti showed up at the Pensacola SAM Champs with one in 2000.

The Duke-The Duchess: the original plan by Larry Eisinger was published in a Fawcett publication booklet titled "Model Builder's Handbook No.1" 1939. He made several similar models that culminated in the Duchess, the most elegant of all his previous models. When Italian modeller Giovanni Ridenti came to USA in the nineties for an oldtimer contest with this plane, all American modellers thought it was an Italian project due to the elegance of the design, and they didn't know or believe it's an American project. It was never published in a model magazine, only in this booklet of which he later became an editor. Only a few plans by Eisinger still exist and he probably ceased aeromodelling in the forties, leaving no trace. I don't know if he is still alive today. Probably this booklet arrived in Rome where foreign magazines were not so difficult to find. For the first issue of Modellismo magazine they reproduced the plan not mentioning Larry and changing the name to The Duke. The plan was reinked by Mario Rodorigo, one of the several Rodorigo Brothers modellers. The plan was adapted for Italian woods, in fact balsa arrived in Italy with the Allied Forces soldiers/modellers at the end of the WW II. The model was built in plywood, hardwood and cork bloc instead of balsa bloc! Italian boys used dried Agave plant fiber that was quite light and similar to balsa wood, called by them Agabalsa. When I was 13 I was fascinated by this model, having the original magazine bought by my father in 1945, and I decided to build it. I completed only the fuselage and I remember that there was an error in the first formers where the engine bearers are located.

Here are some photos of DUCA-DUCHESS-DUCHESSA built by Giovanni Ridenti (his plans are on OZ too), first placed in Pensacola in 2000 [more pics 003-005]. Ridenti modified construction particulars like wing bayonet for splitted wings or reinforcements, but his plane was built on Larry's plan rather than Rodorigo's plan. Two photos with 1939 on the wing are from another modeller [more pics 006, 007].

Ridenti rebuilt a second Duchess [more pics 008] after the first (Pensacola winner) was destroyed in a contest by radio interference.

* 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.
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.
