About this Plan

J.M.34 (JM 34). Rubber duration model. Wingspan 66cm.

Originally designed by José Marchesi of Buenos Aires in 1942. The design was very successful in South American contests in the 1940s and 1950s. Later variants featured a folding propeller and a forward fin.

This plan on Outerzone is a later version, redrawn (at a reduced wingspan of 66cm) by Mario A. Battagion.

Many thanks to Devon Sutcliffe for clarifying a few details re: this plan. The plan description has been updated. We're still not 100% certain of the original designer's name. I'm fairly sure it's "Marchesi", but have also seen it spelled "Marchessi". If anyone can confirm either way, it would be appreciated.

The designer's name is José Marchesi. He was a well known designer and active aeromodeller in the forties and fifties in Argentina. For example, he placed fifth in Class A in the Argentinian competition 'Gran Premio Trofeo Presidente de la Nación' held in October 1949, and this is the way his name was printed in the November 1949 issue of the magazine 'Aeromodelismo' [more pics 003]. Regarding the original JM-34 design, the advertising for this model in the October 1949 issue of the same magazine reads: "J.M. 34. The already famous plane, winner of many contests. Easy to build and very easy to fly too. Complete kit, wingspan 1.80m [71in], price $23. P/P add $3.50" [more pics 004].

I'm proceeding with the realization of this project, sending you two photographs of the fuselage [more pics 005, 006]. As soon as I have finished the construction I will give you some pictures.

I came across with this post and I'm glad his work is still being recognized. His name was Jose Roberto Marchesi, Argentinian from Italian family. He was my grandfather.

I'm José Marchesi's son in law. He was a passionate man for this hobby. I the mentioned years his father also worked hard with him in planes construction but the JM 34 was his own draw/design. José died at his 94 years old and his last plane built by his hands was at his 90s. It was a radio control plane. If you wish, I can send a picture of Jose at the moment we went to fly this plane. It is a pleasure for me and her dauthers see his history in the web..., we only have magazines of those years when he was a young competitor... Best regards (sorry for my poor english)

* 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.
