Lupusprimus Posted December 12, 2018 Author Share Posted December 12, 2018 On the inside of one half of the fuselage approx. 10 mm wide foil strips og 0,5 mm foil are glued as connectors. Quote Link to post Share on other sites
BaconRaygun Posted December 13, 2018 Share Posted December 13, 2018 (edited) Looking good. I gotta hand it to you super-scale RC guys. I would be way to puckered to fly a bird that I spent months (if not years) building. Edited December 13, 2018 by BaconRaygun Quote Link to post Share on other sites
Lupusprimus Posted December 13, 2018 Author Share Posted December 13, 2018 The fuselage halves are glued together. The opening for the mechanics is cut at the bottom at a visible mark. Quote Link to post Share on other sites
Lupusprimus Posted December 14, 2018 Author Share Posted December 14, 2018 In the same order the tail is built at the rear. Quote Link to post Share on other sites
Lupusprimus Posted December 15, 2018 Author Share Posted December 15, 2018 Connecting the main fuselage to the tail section proved to be a little more complicated than thinking. The main fuselage was a bit twisted by the gluing, so that the tail would have been crooked when gluing it together. This happens quickly with larger foil hulls. That's why we usually separate the rear part to compensate for the twisting. Here a carbon tube had to yield (was cut off) and the connectors were glued either inside or outside. The rest was clarified by a spatula. Quote Link to post Share on other sites
Lupusprimus Posted December 16, 2018 Author Share Posted December 16, 2018 The lateral outriggers are also made of two halves. Cut out, glue the connector inside, glue the halves together. Quote Link to post Share on other sites
ice225 Posted December 16, 2018 Share Posted December 16, 2018 It's interesting to see, how you work with that thin and wobbly material. Quote Link to post Share on other sites
Lupusprimus Posted December 16, 2018 Author Share Posted December 16, 2018 The material is not wobbly. As soon as it is glued together, everyone wonders how stiff and stable it becomes. Therefore it makes no sense to deep-draw such hulls from thicker material. This only increases the weight, but hardly the bending stiffness. Quote Link to post Share on other sites
Lupusprimus Posted December 17, 2018 Author Share Posted December 17, 2018 The outriggers for the running gear legs are supported by a cross beam. This absorbs the forces (when landing). The foil alone would not be able to do this sufficiently. It's printed with a simple filament printer. (Here still the older one of Shapeways) Quote Link to post Share on other sites

Lupusprimus Posted December 19, 2018 Author Share Posted December 19, 2018 The outriggers are mounted, adjusted and glued. Dananch applies spatula to smooth the surfaces. Quote Link to post Share on other sites
Lupusprimus Posted December 20, 2018 Author Share Posted December 20, 2018 The assembly of the cabin part begins. These are the required parts. Quote Link to post Share on other sites
Lupusprimus Posted December 21, 2018 Author Share Posted December 21, 2018 The Forestale version has bubble windows on both sides. The foil part is held halfway inside and the outline is marked. First cut a smaller hole. Then carefully trim again and again until the window fits. The window foil must lie cleanly on the inside all around. Quote Link to post Share on other sites
Lupusprimus Posted December 22, 2018 Author Share Posted December 22, 2018 Finally, the window surfaces are protected on the outside with masking tape. Here from Tamiya. Quote Link to post Share on other sites
Lupusprimus Posted December 23, 2018 Author Share Posted December 23, 2018 The two halves of the pulpit are connected on the outside with pieces of Tesa. Inside then small pieces of foil are stuck on as connectors. It is better to mask the large windows on the inside as well, so that no adhesive lands on the foil.

Lupusprimus Posted December 24, 2018 Author Share Posted December 24, 2018 At the bottom, a large piece of foil is glued to the inside of the floor. This also serves to take the load from the nose wheel! The position for the nose wheel is marked on the outside. Inside the counterholder of the nose wheel is glued with a lot of glue.

Lupusprimus Posted December 25, 2018 Author Share Posted December 25, 2018 The cabin part is adapted to the main fuselage and fixed with Tesa. Here it depends on the 90° angle. Quote Link to post Share on other sites
Lupusprimus Posted December 26, 2018 Author Share Posted December 26, 2018 The rear part of the cabin is cut to fit. Quote Link to post Share on other sites
Lupusprimus Posted December 27, 2018 Author Share Posted December 27, 2018 The pulpit is blown out again on the inside and then glued to the main hull. Pay attention to the angles. This must also be true from the front and top. A leaning pulpit does not look good later! Quote Link to post Share on other sites
Lupusprimus Posted December 28, 2018 Author Share Posted December 28, 2018 The rear of the cabin must still be fastened. I had already adapted it. For this purpose small elbows are bent out of foil. Narrow pieces are glued on the right inside, above and below. Not on the left side, because everything is glazed. During the construction I should have made the cut 3 mm further forward. But I didn't think of the fact with the glazing on the left. It must go also in such a way. Quote Link to post Share on other sites
Lupusprimus Posted December 29, 2018 Author Share Posted December 29, 2018 On the left side I cut a slightly smaller frame out of 1 mm sheet. This is glued to the frame on the foil part. The outside of the 1 mm must be enough as an adhesive surface for the back part! Looks good and stops! The rest is clarified by spatula. Quote Link to post Share on other sites
Swashplate Posted December 30, 2018 Share Posted December 30, 2018 You sir, do some amazing work. 👍👍👍👍👍 Quote Link to post Share on other sites
Lupusprimus Posted December 30, 2018 Author Share Posted December 30, 2018 Thank you all for your appreciative comments. The landing gear legs are plugged in. From above I apply gentle pressure to the fuselage. Nothing bends there. The fuselage will withstand 600 g in total. I would have been surprised, if not. Quote Link to post Share on other sites
midnightprowler Posted December 30, 2018 Share Posted December 30, 2018 Looking good. I for one would like to see a video of this bird flying. Quote Link to post Share on other sites
