Alex Ilea Posted January 20, 2024 Posted January 20, 2024 (edited) Hi everyone! This is my latest B-model Alternate, of the 42145 Airbus H175 Rescue Helicopter. It is a MOC of a two Seat Ornithopter that can be found in the movie "Dune": The idea for this alternate came from some people in the Romanian LUG members, who said it would be awesome if I made it happen... So I did! The main scale factor were the blade pieces in this case, which ended up looking pretty good! This build is bulkier than the "real thing" since all of the motorized functions. The Powered UP battery really took a lot of the space.... It features 3 motorized functions controlled by a cabin lever for the battery box and 2 switches found on the side and top of the model. The side switch has a reverse function for the blades deployment, while to top lever switches between the landing feet and fly mode (flapping blades). Motorized Features: -expanding blades -flapping blades -deployable landing feet I would like to talk a bit about the making of this MOC. I want to first say that it was a very interesting challenge to replicate the blade deployment and flapping just like the real thing. From the start I knew I wanted all the functions to be motorized. I thought the landing feet are doable, but I had no idea how to make the blades mechanism. I researched the real Ornithopter mechanism, but I didn't feel it could be done just with the parts in this set, so as it usually goes with B models, I improvised and came up with my own. You can think of the flapping mechanism almost like a kinetical sculpture that moves in perpetually. Each side is it's own mechanism and is mirrored on the other side. The gearbox responsible for this function is on the top of the build. The deployment of the blades is simple, using the 6L links provided by the set. The one worm gear provided in the set operates the right side and a linkage system deploys the left side. For this function I had enough space to add a reversible gearbox, like we get in Technic sets these days...The switch is on the right side. The landing feet were surprisingly difficult to build. The mechanism is based on a linear actuator controlled by the top switch (check how it works in the video at 1:15). Model dimensions (with stand included): Length: 36cm/14.2in Width: 15cm/5.9in (blades closed), 60cm/23.6 (blades open) Height: 20cm/7.9 This is the first time that I post a model with renders instead of photos, please let me know if you prefer this way. Also I had a lot of fun playing with AI to create those background images that you see at first, and then editing the model to look like it is going trough sand. Of course I am still learning and my edits will get better over time. I also made a small stand to display the model, I think it looks appropriate here.

2GodBDGlory Posted January 20, 2024 Posted January 20, 2024 Quite a creative idea, and nicely done! It's always interesting when people build things like the wing mechanism here, because there's not really precedent you can copy--you have to invent things yourself! The Airbus is looking to be a really good base for alternate models, at least if you don't need wheels! Quote
vascolp Posted January 20, 2024 Posted January 20, 2024 This is really cool! Back in november, after seeing the images from Lego Ornithopter 10327, I did a prototype for that mechanism, and I know some of the difficulties. It was an idea for TC26… but unfortunately no time for it. And yours, made as a C-model! Well done! Quote

I actually built this model right before Lego reveled their ornithopter, bu thust never really posted it. It was about time now! Quote
