JT-5 1973, OH-XYS. This was going to be one the most beautiful
autogyros yet to be seen. I designed the machine in 1969. The building
started in 1970 with Aulis Eerola, but soon after he left to pursue his
own helicopter businesses. Nevertheless he welded the fuselage and did
some machining. The cockpit plug and mold was a big job. The cockpit itself was of honeycomb sandwich construction with a fully enclosed blown canopy. Even the landing gear was of glass reinforced epoxy. The engine was a brand-new 1700 ccm engine from Limbach in Germany. The JT-5 flew well right from the start. It was fast, 165 km/h, and very maneuverable. Information about JT-5: HOMEBUILT AIRCRAFT, October 1979. Take a look at a copy of this article by Walter Shelbourne. It also includes JT-5 dimensions, weights and a performance summary. Jane's All The World's Aircraft 1974-1975 edition

In 1974 I sold the machine with all production rights to Mr. Vittorio Magni of Italy. He renamed the machine as 455MT-5, then M-5 and it looks like its latest incarnation is Magni M20 Talon although with a different engine? Well, sometimes I miss my baby, it was a very nice gyro to fly. The JT-5 prototype is still on display in the Magni Factory Museum near Milan (picture below). Three more JT-5 autogyros have been built in Finland and one in Sweden. Several others are under construction. OH-XYX was built by the brothers Arvo and Hannu Taupila, who also have built JT-5 rotor blades for other homebuilders. Now they are building a 2-seat training machine of their own design. | ||||||||
40 years from the JT-5 design! I started to design the JT-5 gyro
in 1969 and the first flight was in 1973. Since about 40 years has
passed of those times I have decided to publish the drawings for free
on these pages. Drawings: There is more information of the JT-5 construction methods on the JT-5 builders pages | ||||||||

Jag är imponerad av din
webbsida om autogyros och har läst den med stort intresse. Du måste
vara en av de personer i världen som har mest erfarenhet och kunskap på
detta område. Det är imponerande att du hunnit med så många verkligt
banbrytande pionärprojekt i ditt liv, trots att du har haft arbete och
dessutom hunnit med en massa flygtimmar och att spela dragspel! I much admire your work and website but do you have any plans available for an autogyro, one or two seat? I certainly appreciate your release of your JT-5B plans which I
have spent hours studying. I find them very complete and thorough. I
have been researching gyro designs for some time and I am finding that
many manufactures are following your designs, some with slight
modification. Your contribution to the world of good gyrocopter design
is recognized by many. Thanks
you so much for sharing your work on gyros..your accomplishments are
extraordinary! Your graphics are sensational!! I intend to visit your
site many times, and truly enjoy it. I'm
writing you from Montreal, Canada. I've been visiting your web site for
quite a while and must say that every time I do, I find myself
dreaming. You have designed and built a jewel. My
name is Juciê and I live in São Paulo, Brazil.. I am a big fan of
yours. I think your web site is amazing. The drawings arrived. I am
delightfully studying each sheet. Beyond engineering, that is a fine
piece of art. Congratulations. Oliver J. Wilcockson Your web-site is amazing, I am so impressed with your projects and drawings. Steve McDaniel | ||||||||
