Yeah it is :) Can't wait to see the top five. And yeah, I thought 1 week would be enough. Most of the people who were really excited about the contest voted in the first 2-3 days.

4 more days people....

I am dying to know how my entry will do

Well, you could take it apart and reconnect the battery. It might help...

The servo calibration is available on Android phones, but it doesn't work nearly as good as Buwizz app itself. Brickcontroller 2 would be perfect if it had the better steering calibration and a version of Buwizz's own tracked steer module.

It is really cool how it turned out, I am impressed myself :) I actually built this model right before Lego reveled their ornithopter, bu thust never really posted it. It was about time now!

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.

I am really proud of this build. Thank you so much everyone!

Very cool model, congratulations! I really like that it is so function packed. It looks to be in the same scale as the Arocs set, so it would look really nice next to it.

I think 1 week should be enough. Yes it helped, but the best would have been to have a picture next to each of the dragging entries. Would be a cleaner experience. But it was alright in the end

I have voted yesterday and it was a nice process, as people said before, to compare each entry and refine the final list. One thing which would have been better is to add a picture next to each entry on the voting site, to make it easier to arrange and not alt tab.

Wow, very well executed!

I understand that, but why not make it comparable to the competition? Why be different for no real advantage? Yes Radio is a huge upgrade, but port limitation would detract some portential buyers. This product would be a direct competitor to Buwizz 3.0, so you would need to make it appealing to more people than just to a small category. And regarding the ports, imagine you build a Lego version of the Traxxas Bronco: you need drive, steering, 1 port for gearbox, 1 port for front diff, 1 port for rear diff.

This looks interesting and I can see the use for such control unit with a Radio Control. I do however have to say that the ports seem to be in a very bad place. Why not add 2 more PF ports or 2 more PU ports? Look at Buwizz 3.0, the design of the ports is quite good, but not perfect. In the BW case, after you fill all the PU ports and you want to add the PF connectors, the PF cables will be bent in a less than ideal way, and this is something you should try to improve on.

I bought the tickets for Buwizz Camp 2024 a month ago. I hope to see there as many people as possible and possibly fellow members from here. Competition is always good (plus, the challenges are quite interesting and will definitely produce a nice video).

Is that a new mold for the 3L driving ring? Looks weird on lego.com

Wow, the functionality is really cool!

This looks awesome! I especially like the big A frame used in the outside of the front tracks, well done.

Looks kind of cool striped down like this.

ARCTIC TRANSPORT BASE Functions (base): Drive (2L motors) Adjustable Ride Height (for easier loading) Openable Rear Access Ramp Detachable Cockpit Working Twin V8 Engines + Spinning Cooler Fans Rotating Satellites Functions (explorer): Drive (the same 2L motors) Winch (L motor) Boogie Suspension Switch box (M motor to switch between explorer functions and base functions) The small explorer can self load in the garage of the base and control it after using the switch box. YouTube Video: Discussion Topic: Thank you, Alex

Those cardans control the satelites, so they don't influence the power to the tracks that much.

This model really pushes the limits of plastic, so it was the best I could do without making it ULTRA slow. It was never my intention to make the small model the "main one", but the small one was the logical choice as the housing for the motors. Hahaha! And no, I don't even have the 42100 set unfortunately... Thank you all for the feedback and positive coments!

Thank you guys! The truth is, this whole build is just beyond the limit of what the Lego system can do (plastic is plastic). Yes the Base can steer, but it is very very slow. You are right, the bevel gears (which I tried) join better when self loading, but they are just ever so slightly smaller in depth contact between them and would skip more than the straight teeth ones. In other words, the ones I used just mesh better than the other ones.

It might be the color grading, they are DBG from the E-tron set. Appreciate the compliment, this project has really beed a mind twister!

Hi everyone, I would like to show you my entry for the Arctic Vehicle Contest. I will preface this by saying that this is my biggest MOC ever, therefore a new experience that was worth the work. So I built, what I call an Arctic Transport Base. The concept is quite simple, it is machine that has a "garage" built in it and can store a small Tracked Explorer inside it and can carry it around wherever needed. The building of this behemoth has been interesting, and I will try to explain as professionally as possible how it works. There is the mini Tracked Explorer that can be stored inside of the Base, and it contains all of the electronics: - 3 Large Powered Up motors -1 Medium motor -1 BuWizz 3.0 brick The 3 L motors operate the "big functions" and the M motor operates a switch box (via a small liniar actuator) located in the rear of the Tracked Explorer. On it's own, in the first position of the rings, it can drive the two tracks and operate the powerful winch in the front: Notice how I used the 20T clutch gear for perpendicular drive to the tracks. There is also a small interior present. The Base has a height adjustment + ramp raise/lower system that is controlled with the motors inside of the Explorer. And the Explorer can self load inside of the Base, use M motor to switch the rings and control the functions of the base. I know, complicated ;) You will see the 3 blue gear in the rear of the Explorer, that will mesh with the azure gears inside of the Base to operate the other functions: The ramp and garage have guidance channels to facilitate easier loading. Once the Explorer self loads (the ramp and the whole Base is lowered) the switching happens and the left and right motors control the 6 tracks of the Base and the middle L motor controls the height adjustment and opening of the ramp (see video for better visualization): In the Base, the L motors that operate the tracks also operate the two satellite antennas, two V8 engines and two fans in the front. There is also a detachable cabin to expose the internals: Now, based on the discussions here, @Jim said it is ok to build such a thing, where the smaller vehicle fits inside the big main build, but I still need the seal of approval before I post it in the entry topic (because I can see it could spark some discussion). Please let me know :) Thank you for reading and I hope you enjoy this build!
