  1. 1/18 scale Jukka Tervamäki JT-9T autogyro scratchbuilt model Having tried my (suicidal) virgin 40 minutes flight experience with a friend's homemade autogyro during my summer holidays with him on flight controls and me on the passenger's backseat, I can surely say that you really feel like a bird, sensing even the slightest airwave or gravity accelerating change straight in your floating stomach. As soon as I safely stepped on solid ground again and returned back home in one piece, I felt the iresistable temptation to try a 1/18 scale autogyro scratchbuild. The following article is to describe step by step the 1/18 scale Jukka Tervamäki Engineering JT-9T autogyro, designed by Mr. Jukka Tervamäki and currently flying by ultralight aviators around the world keeping the Mad Max II GyroCaptain's (aka Road Warrior) spirit alive! In the photo below, Mr. Jukka Tervamäki, with his latest (at that time) creation of the JT-5, which was a predecessor of JT-9, which I'll try to represent in scale. The basic JT-9 autogyro concept is about a tractor gyro design with good aesthetics and performance with fairly low power. A 1.7 m diameter 2-blades propeller is powered by HKS 700 or Hexadyne Aviation P60 diesel engines, both delivering about of 65 hp at 2400 rpm. The fuselage of the JT-9 is of normal steel tube construction covered with dacron fabric. On the other hand, the JT-9B model is equipped with an electric motor instead of a diesel engine, with only difference the 3-blades propeller and wider front cover to house the battery packs onto both sides of the fuselage. The model I'll try to build in 1/18 scale, is the two-seat trainer (as for the "T") JT-9T model, equiped with diesel engine & 2-blades propeller made by carbon fibers. Having the basic blueprint line diagrams in hand, it was easy to convert them into 1/18 scale with a photocopier and I began the scale model building, starting from zero using 0.25mm styrene card and plastic sprue. To make the construction look more interesting, I decide to build the model in a way that airframe should look like cutaway side opened and let cockpit detail be easily observed. In the following pictures, the real (one-seat) Alex “GyroBeast2” Lameko's autogyro JT-9, during the successive stages of building.
  2. 1/18 scale Wallis WA-116 Agile autogyro 3D printed / scratchbuilt model The following construction is a tribute to RAF Wing Commander Kenneth Horatio Wallis DSO MBE CEng FRAeS PhD, a pioneer gyrocopter aviator, who passed away early on Sunday morning, September 1st 2013. Ken was 97 years old. During the WWII, Wallis served in the Royal Air Force as Westland Lysander and Wellington pilot and flew 28 bomber missions over Germany. After the War, he flew the massive Convair B-36 and later involved in research and development, before retiring in 1964. He later became one of the leading exponents of autogyros and earned 34 world records, still holding eight of them at the time of his death. He was an inspiration to us all and we shall greatly miss him. A local hero and a national treasure. He was born on the 26th April 1916, at Ely in Cambridgeshire. With his father and uncle having built an aeroplane in 1908 to fly the channel in a competition that was eventually won by Louis Bleriot, Ken Wallis acquired an interest in practical mechanics at an early age and by the time he was eleven years old had built his own motorcycle. He eventually turned his attention to aviation following a flying demonstration he watched in 1936 of the Henri Mignet HM-14 Flying Flea / Pou Du Ciel. Ken will be greatly missed by the Flixton museum members. He was a frequent visitor, generous fundraiser and a great ambassador. In addition to the numerous professional institutions who welcomed Ken as a member and the vast number of clubs who regarded him with great respect and fondness, many ordinary people will also feel a loss in one way or another. Even a short chat with him left the individual feeling that it was something special and his warmth made them feel that he would remember them! Ken was recognised wherever he went. Admirers would soon gather and he would usually produce a small clipboard from a pocket, to sign and give away autographed postcards of him flying the “Little Nellieâ€. I am sure that many a childless adult has asked for a card to give to their “offspringâ€. Ken was inspirational, a great role model and possessed a rare old-world charm plus the impeccable manners of his age; all without a hint of grandeur. I am not alone in thinking that he was probably the grandfather figure we would all have liked to have had at some time. Norfolk was Ken's home from 1963 and I venture to think he was appreciated by such a large part of its population that he was likely a close second to its most revered inhabitant: Horatio Nelson. Goodbye Ken - our gyrocopter aviation hero and national treasure.
