      Jeg må spørre; finnes det noen lignende 3D printede modeller der ute? Jeg har sett at det finnes betydelig mindre modeller, men har aldri sett noe så stort og omfattende som dette.

        Ikke som jeg vet om. Jeg kommer sannsynligvis til å lage en til i samme størrelse, for samme vifte. Muligens He-162.

        Husk at det ikke er L-39, men EL-39.

          Klarte å kræsje prototypen litt i dag under landing, men da passer det jo bra at nummer to er klar for å flytte over utstyr.

              Ferdig nå, og vekten ble 7950 g i følge vektene mine. Regner med den flyr fint. Kanskje jeg tester i helga.

                Prototypen er reparert og hengt opp i garasjen. Første gang jeg har reparert et 3D-printet fly. Jeg kuttet vekk hele delen som var ødelagt med båndsaga mi og limte på ny. Hver vinge hadde én skadet del hvor busker hadde trykt inn forkanten, og nesa måtte byttes. Nesa var skrudd fast til flyet så den var enkelt å bytte ut.

                      I dag lagde jeg deksler til flaps-mekanismen. Bare pynt på denne siden den ikke har fowler flaps som full size, men det må til. Jeg lagde også håndtak til canopyene. Delene ligger på Cults-siden sammen med flyet:
                      EDIT - 29.08.2023 I added a reinforcement block (WingReinforcement.stl) for the inner wing panel that increases the torsional rigidity of the wing by preventing deformation of a weak spot under landing loads. Install according to the illustration. I also added a new impeller for the EDF that sounds great and might give a slight performance improvement (Gleich-Impeller07-12b-fat-Newblade.stl). EDIT - 20.05.2022: New EDF impeller with 18 blades. It sounds much better and performs well. Flight video: https://youtu.be/XvHo3N9S8D0 EDIT - 20.09.2021: New front nose piece with clamshell hatch for making access to a battery or whatever you want to put in the nose. Use an M3 screw to hold it closed. EDIT -22.07.2021: Added a new EDF housing that can use the HET motor without any heatsink because the heat sink can be hard to find now. EDF-housing04-Noheatsink.stl It supports the motor all the way through and has a gap for air to pass around the motor. It should be printed from a more heat resistant material than PLA, and that goes for the impeller as well because the lack of an extra heatsink can raise the motor and axle temperature to where the PLA will start to soften. EDIT: Added a new canopy that is one main piece instead of two for printing in a very large printer (in addition to the front windshield part). The new files are Canopy01-onepiece and canopy02-onepiece. The human is not included. Specifications: Length: 1858,5 mm Wingspan: 1451 mm All up weight: 7,2 kg (prototype #1), 8 kg (prototype #2), 7,5 kg (prototype #3) CG: 83-103 mm from the leading edge at the wing joint with the gear in the up position. There is a protrusion on the top of each wing surface to indicate the safe 83mm/25% MAC position. Gear up or down should make little difference because of the low weight of the nose gear. The prototype maidened with CG at approximately 90 mm. 103 mm CG has been tested and flies very well. Needs a large printer. 300x300x300 is recommended. Initial control throws: Elevator: Up 18 mm / Down 16 mm Ailerons: Up 20 mm / Down 15 mm Rudder: 15mm / 15 mm Use 30% exponential on all surfaces to reduce center sensitivity. Appropriate pilot figure: https://www.thingiverse.com/thing:2970724 Video of the prototype without flaps: https://youtu.be/znbaBhUY25k Maiden videos: https://www.youtube.com/watch?v=9tShEHO5M5s https://www.youtube.com/watch?v=Gp0sF1WKZ7w High speed fly bys and landings compilation: https://youtu.be/KzPiHn8WywE Onboard videos: https://www.youtube.com/watch?v=uDD7gKV2YSY https://www.youtube.com/watch?v=_93jys9oADY Various flight videos: https://www.youtube.com/watch?v=VcE9QgbNThE https://www.youtube.com/watch?v=jZJCof5v06M https://www.youtube.com/watch?v=DpYUfhk2Kec https://www.youtube.com/watch?v=E4S3TekVd6I https://www.youtube.com/watch?v=JWw4-YrTFSI https://www.youtube.com/watch?v=fBd4eTZwPW4 https://www.youtube.com/watch?v=LnProCnHUOs https://www.youtube.com/watch?v=1EPln7NoYhA https://www.youtube.com/watch?v=67ruv_F0Jjk Build notes and BOM is moved to the text file BuildNotes.txt because of new limitations on Cults when i updated the page 17.11.2020.

                        Klør litt i fingrene etter større printer nå altså. Flott arbeid du gjør, modellen er jo helt rå

                          Trist måte å miste et fly på. Nesten verre enn å kræsje. Sola tok knekken på det i dag. Det smelta.

                              Ja det burde fungere bedre. Blank finish også.
