CHAPTER V - "H" shaped tail construction The Jukka Tervamäki Engineering JT-9T autogyro designed by Finnish engineer Mr. Jukka Tervamäki, is equipped with a twin "H" shaped tail. To build this, I started by rolling flexible styrene sheet around a plastic tube and forming as required to look like th...

Re: 1/18 scale Jukka Tervamäki Engineering JT-9T autogyro sc
Remember the previously mentioned wooden picture frames, found at the local IKEA store for only 1€ each, securing the styrene plastic sheet to be vacuum formed? I kept these thin plexiglass plates, to use them as required. Continuing the cockpit construction, I had to build the rear cockpit cover, s...

Re: 1/18 scale Jukka Tervamäki Engineering JT-9T autogyro sc
Using the proper Black & Decker saw tool, a 34mm wide hole was drilled through the side of the box to facilitate a vacuum cleaner fitting. Luckily, last week I found a real bargain at the local Media Markt store and I bought a 1600W brand new Hyundai HVC-6003 vacuum cleaner for 15€ only. I decide to...

Re: 1/18 scale Jukka Tervamäki Engineering JT-9T autogyro sc
To produce a thin-skinned right side fuselage, the polyester part, must be vacuum formed. That means, that I should build from the beginning a new vacuum chamber box. Vacuum forming is a very simple technique that can produce thin-skinned parts of various forms. I mainly used vacuum forming for prod...

Each one of the two complete custom-made kits consists of 60 different 3D printed parts, some quite big and some others so tiny that could be easily become victims of the carpet monster. The only difference between these two Kriegsmarine’s V6 and Luftwaffe’s V21 custom-made complete kits, is that th...

Re: 1/18 scale Flettner Fl-282 V21 Kolibri scratchbuild mode
Shortly thereafter, the 3D printing proceeding outcome pleased me while watching the Mbytes, magically converting into actual physical objects. Yeah, that’s what I call “cool gadgets” on a scale modeler’s service. As soon as 3D printing process completed, the produced parts were cleaned & checked fo...

Re: 1/18 scale Flettner Fl-282 V21 Kolibri scratchbuild mode
After digitally building the Fl-282 Kolibri 3D model using only mouse clicks, I saved it as an STL - STereoLithography format binary file and forward it on the 3D replicator to start generating the individual parts of the actual scale model. To do so, I used the best available tools & plastic materi...

Re: 1/18 scale Flettner Fl-282 V21 Kolibri scratchbuild mode
Some additional parts unrelated to the helicopter structure, also designed to get 3D printed later and be used later as part of a diorama scene. For example a couple of 200 litres fuel drums (also known as 55 gallons drums in USA) and few 20 litres (4.4 imp gal; 5.3 US gal) “Jerrycan” fuel canisters...

Re: 1/18 scale Flettner Fl-282 V21 Kolibri scratchbuild mode
As previously said, I found interesting idea to have the 7-cylinders radial engine would be installed inside the helicopter's belly in the fuselage center-section (and become almost hidden) and also 3D print a second removed engine, place it on a wheeled stand and present it nearby, as it would be t...

This is the 3D design of one of the two rotor heads, equipped with vibration dampers “pots” on the blade roots. Each one of the separately 3D printed rotor blades, will be later attached on the blade root connecting hinges and the outcome will be installed on gearbox shafts, having an included angle...

Re: 1/18 scale Flettner Fl-282 V21 Kolibri scratchbuild mode
The doped fabric cover over the truss-type welded tubes & wooden ribs is about 0.4 mm thick (in some special areas about 0.7 mm). Thinking as a rivet counter, this 0.4 to 0.7 mm thick “fabric cover” could be considered as an out-of-scale unforgivable mistake, having always in mind that it does repre...

Re: 1/18 scale Flettner Fl-282 V21 Kolibri scratchbuild mode
The biggest part of the kit are the 4 rotor blades measuring approx 28 cm long each. The fuselage was CAD designed such way and later 3D printed into two main section parts with all included truss-type welded tubes and drive shaft rods with universal joints inside. That was mostly preferred for me, ...

Re: 1/18 scale Flettner Fl-282 V21 Kolibri scratchbuild mode
This is the complex of intermeshing rotor gearbox. It turned out (as happened in the actual helicopter) that it was the hardest and most complicated part to build, because it was not easy for me to get a technical manual describing the gearbox in detail. Fortunately (thanks to Deutsches Marinemuseum...
