Heavy LEGO Technic amphibious tracked vehicle, build and test.
A few years ago I built my first amphibious vehicle, the Behemoth. Now, it's time for an upgraded version of the tracked monstrosity to undergo sea trial tests! The tests will help me further develop the vehicle to an Mk-III version capable of traversing open water and landing on small islands!
Enjoy!
Behenmoth Mk-II specs :
Water propulsion : 2x LEGO RC motors
Tracks : 2x LEGO XL motors
Battery : 3-cell LiPo
Remote Controller : FlySky FS-i6 with 6-channel receiver
Electronic Speed Controls (ESCs) : 2x Hobbywing Quicrun 1060 (for the XL motors), 2x Hobbywing Quicrun 880 (for the RC motors)
Footage was shot on DJI Mavic Mini drone (aerial), DJI Action 2 (forward facing onboard and build process close-ups), GoPro Hero 3 (rear facing onboard), LG G6 cellphone (beach footage), and Google Pixel 6a cellphone (build process).

As a lego technic master... this is by far the most beautiful machine I have ever feast my eyes on... Great build by the way 👏👏👍👍👍🙂🙂🙂 Pin pls
Pin it? Why not...
That bathtube test with batteries not properly secured was scary :D
Yeap!
@@brickandgear A bathtube sounds dangerous.🤔
@@OGbobbylocdogg 😁
The most unusual construction from the constructor that I have ever seen. Nice!
This vehicle is probably the end of an era. In the future I will most likely use 3d printed fillings instead of styrofoam, so my designs will be much better!
Shouldn't it be Leviathan, instead of Behemoth, since it's swimming in the sea 😅 Great video btw!
Makes sense
When I build a proper submarine I'll name it Leviathan! Deal?
behemoth is believed to be inspired by hippos, which are semi aquatic. this is semi aquatic and also has a more girthy silhouette. definitely fits the name
@@frank_calvert love the scientific answer. My kind of guy...
@@frank_calvert Really? I didn't know that. You learn something new every day. I guess he was scary to the ancient people so they made stories about hippos xD
That was kind of meditative to watch. 😇 The calm style of the video, the water, the nice beach...it gave me some chills 💆♂🤤
That was my intention! I'm glad you enjoyed it!
Can we just appreciate that this goat answers every single comment
Yes... Yes we should... 😁
Nice to see you back Brick Gear 👋 this looks amazing 👍
Nice to be back!
I always tell the kids in my club: "If you need to use more than three frames, you are doing something wrong." However we don't usually build meter long tanks with giant polystyrene block holding cages. Guess I should stipulate that it depends on the context.
You run a building club? Please elaborate! 🙂
@@brickandgear Oh, it's a delight! In my country, school clubs aren't very common, but we have an organization that runs free time centers for children and youth. There's all sorts of clubs, chess, ball games, board games, Nerf, woodworking, electronics, street dance, photography, programming, 3d modelling, outdoorsmanship, and what not, and I happen to preside over the Lego robotics club for about five years now. Once a week, after the free time afterschool club is done, we go into the club room, take the boxes from the wardrobe and line them up on the pool table, and we go to town on them. We have about eight EV3 boxes worth of parts, plus three organizers with drawers, and lately, since you can't get new EV3 sets, we've been experimenting with Nezha robot inventor kits. There's eight kids, but usually at least one is absent. I enforce the reasonable frame usage rule, and others like it, because their first instinct is usually to just get the frames and build a huge platform out of them, which first of all is floppy, second makes it hard to connect the functional elements, and most importantly, leaves no frames for others. Depending on the assignment, they work alone or in pairs, to build whatever they need. I either let them pick what they want to do, or if they can't decide I pitch some sort of an idea or a challenge for them. Past few years I've been working with smaller kids, about 9-11 I think, so I don't expect anything groundbreaking from them, it took a pretty long time to make them stop building skewed deformed shapes, and cars entirely out of axles, but sometimes they surprise me with what they can come up with. We do standard stuff, like sumo or battle bots, line follower and dragster races, seeing who can build the best lifting mechanism, or just experiments, like sound or light activated robots, and such. Sometimes they're not easy to work with, since they're children, and ones with phones at that, but I got a couple of aces up my sleeves. When it's a special occasion, I hook the projector up to my laptop, and we catch some inspiration by trying out ideas in Scrap Mechanic, and they don't even notice they're learning. Other times, I get my specialty, and I show them shooting mechanisms. They really like those, although they seem a bit bored when I start by explaining firearm safety. One time one of the older boys came up with the same mechanism I had prepared, but actually improved upon it. Then when everybody had built themselves a little blaster, we had a target shooting competition. It's an awesome feeling when you see a child has learned something from you, and uses it to create something interesting, but the main perk: when they're not in need of my help, I get access to a huge supply of Lego.
Good to see that I'm not the only one that is fascinated by lego's versatility. Where was the footage for the sea trial shot?
Hello! This is the location of the sea trial on Google Maps : maps.app.goo.gl/XH1syYo8ckJgtMJg7
Impressive build! Love the sounds it makes.
You should definitely check out my landing craft videos. The sounds that baby makes when the ramp is retracted during arrival are mesmerizing!
It's amazing, what a beast
Thank you!
Amizing vehicle I think thats a LandShip Now Very Kool👍👍👍
Thank you! 🙏 The next version will be able to handle a proper island landing! I've already chosen an island 400 meters from the shore. Quite the journey!
Wow!! That's super cool!!
Thank you!
very impressive, magnificent build
Thank you!
Amazing vehicle man well done!
Thank you! 🙏
Seeing that angle in the front so beautiful
True!
My son and I are gradually getting in to Technic Lego, your video is inspirational. I never even considered this sort of thing was possible, great fun thank you. Now back to our John Deere Skidder... 😀
Imagine the possibilities with more durable building materials and advanced tech. We live in great scientific times!
Πολύ ωραία κατασκευή 👏
Ευχαριστώ πολύ! Δυστυχώς δεν ήταν σε θέση να κάνει απόβαση στο νησάκι, αλλά τα παθήματα θα γίνουν μαθήματα. Πάμε για την έκδοση Mk-III τώρα!
A Behemoth in the water and some Sax on the Beach, a perfect Day 😉 Thanks for Sharing! Hang Loose 🤙🏼🍀🏴☠️
Thanks for watching! 🙏
Ok this look really sick
Yeap! 😁
That is cool as heck!
Thank you! 🙏
What an amazing biuld, i love watching your videos, it is sooooo cool and relaxing. Keep up the good work🤩😃
Thank you! I hope you enjoy my next projects as well! 😊
Amazing. 👍😃
Thank you! 🙏
Absolutely awesome build and video! I wonder if adding some mass to the center of the hull, below the waterline, might help with stability? Might need to remove mass elsewhere and/or add more buoyant elements to preserve function, but low-mounted ballast might help counter the roll tendency in rough waters. Well done, I wish I had the resources to do something like this myself but I am content to live vicariously through your channel!
You are correct! This is the last of the "first generation" amphibious vehicles, using foam fillings for buoyancy. This method of keeping my builds afloat was quite restrictive when it came to designing each vehicle. My "second generation" vehicles will use 3D printed fillings, so I'll be free to design the vehicle exactly how I want it and then print the buoyant parts and properly place ballast. I'm also planning to design water tight boxes for the motors and electronics so that I don't have to place them on top of the vehicle.
Its cool that from the gopro perspective and Microphone the Electric motors kinda sound like big turbodiesel Engines haha
That is the reason why one of my favorite videos is this : kzhead.info/sun/bN6GqcmOjWiqrJE/bejne.htmlsi=sChrBul7QiM9UJQ1 The onboard sound of the engines, the rudder and the ramp going up/down are mesmerizing!
$3000 in legos later. RC toy accomplished.
😁
Hmm, the bigger it is, the worse the wind will be. Glad you did'nt have to go after it :)
The next version will go on a diet, and I'll definitely add a spring mechanism to keep the tracks under tension and avoid them getting caught in underwater currents.
Very cool
Thank you!
wow you must have a couple of thousand bucks worth of LEGO ! amazing innovative project .
Thank you! Probably, yes. I hope the channel grows even bigger and I can expand my collection to build even bigger vehicles!
You should try 3D printing. Lego is so expensive for plastic, its the brand name that you're paying for like some clothes
@@deskmat9874 I actually just bought an entry level 3D printer to print custom parts for my boats and amphibious vehicles. However, I don't want to print a whole vehicle for the following reasons : 1. I love LEGO, RC, and the outdoors, so this channel is actually the way to satisfy all three! 2. I don't have to keep/store all of my builds. I just disassemble them and move to the next one. Very convenient with my almost non-existent storage space. 3. I really enjoy the challenge of building machines with LEGO, and solving all the problems that occur due to the limitations of the material.

Man ur a genuis 😮
Thank you!
Awesome
😁
For a second, when I saw the thumbnail I was was "no way this guy built a life-sized Lego amphibious tank. When I pressed on the vid, I was like "oh"
Keep watching the channel and you never know. Someday... 😁
Мужик, ты класс!!!!👍👍💪
Спасибо!!!
Nice! ;)
Thank you!
This has gave me a good idear for YOUR NEXT UPGRADE. Have it equipped with multi directional motor's with GPS stability (not to difficult with drone flight controllers nowadays). And build a rescue winch that you could hopefully rescue a simulated lost drone perhaps. Similer to floating oil rigs. Obviously it may have to be wider again for wave stability and include a GoPro attached to the winching hook. How hard could it be 🤷♂️. You got a week, I'll even subscribe now. Thanks for the video. 👍
There is something similar in my "To Do" list (not with the GPS stuff). Sink a small ship and build a bigger ship to salvage the smaller one...
@@brickandgear That would be awesome. I suppose various anchors should hopefully keep the rescue Vessel in place to carry out a rescue of the smaller boat. Look forward to it.
Underwater GoPro next? Would have been beautiful shots.
I'll use my DJI Action 2 on a submersible platform in the future!
3:00 love it when engineers do this irl
😁
που ωραία φάση εχω να πω δυο πράγματα 1 πες μας και δυο λογία για την κατασκευή και 2 αυτό είναι έτοιμο κιτ ήτα συγκέντρωσες από διαφορετικά κομμάτια
1. Σκέφτομαι για να μην επιβαρύνω πολύ το βίντεο της κατασκευής και δοκιμής, να ανεβάζω ένα ξεχωριστό με σχόλια πάνω στο όχημα. Που πέτυχε, που απέτυχε και τις βελτιώσεις που σκέφτομαι να κάνω στο μέλλον. 2. Τα περισσότερα από τα κομμάτια του προέρχονται από το Bucket wheel excavator και κάποια τα έχω πάρει από το BrickLink.
Which app do you use to create the design of the boat? Thanks. Great Video
I've been using LEGO Digital Designer for all my builds. However, it is not supported any more, so I'll have to switch to Studio in the future.
I like
Thank you! 🙏
σε ασχετη νοτα, το πρωτο μισο θα μπορουσε να θεωρηθει και ASMR βιντεο με τα κουμπωματα των εξαρτηματων!
Αυτός ήταν και ο στόχος! Δεν θα δείχνω πλέον τα πάντα από την συναρμολόγηση. Μόνο τα σημεία κλειδιά σε τόνους ASMR.
A nice toy. I wonder wich beach is that?
It's a small beach south of Athens, Greece.
I think this the first time I have seen an amphibian move faster on water than land.
Yeah, my amphibious vehicles are usually faster on water. The next generation will be much faster and capable on land!
It’s certainly a chonker
Yeap! Mk-III will probably go on a diet...
Scorpa Trials Quad prototype (google picture, white ultra light quad). e-4WD 4 Hubs
Jesus K Kryst, are you completely bonkers?!?!
Yes... 😁
@@brickandgear cool 🤙🏼😜
Is it possible for you to build a lego rc ship that's triple the size compared to the other ships you built?
I recently got some more parts for that purpose actually. I want to build an aircraft carrier that launches small RC planes. I can't say if it's going to be triple the size of my other ships, but it's going to be big...
When I saw the thumbnail I thought you used 2 lego city boat hulls, mounted the electronics inside of them and put tracks around them.
Nope. That would be too small for my taste...
Would you apply water sealant or no?
Nope. I haven't applied any sealant so far on the motors or electronics.
@@brickandgear ic, but if you do, would it affect the contraption handling and buoyancy? Like would it help or no? considering Lego is not quite sealed as it would be once topped together
Filling the hull with blocks of styrofoam provides enough buoyancy. Applying sealant on the bricks would probably make any boat a bit more buoyant, but risking damage to my pieces and having to clean them one by one after disassembly is not worth it.
That was nice navigation thru rough water. Thought you were gonna use the drone to pick it up if out of battery juice
My Mavic Mini would definitely end up in the water if it tried to pick that beast up! 😁
Tenta fazer um barco ou outra coisa que resista a ondas fortes seria muito legal
Construir um barco que aguente mar agitado e mau tempo é definitivamente um dos meus projetos futuros!
How do you even begin to design something like this
You start small and develop. If you check out my older projects, you'll find smaller amphibious vehicles that led to this. The next version of the Behemoth will be much better. I've already thought of a few improvements.
Are the rubber tracks lego??
Yes, they are LEGO.
What propellers do you use?
I use propellers for RC boats fitted with 3-stud Technic axles. You can check the tutorial here : kzhead.info/sun/fbyzmJRupnlraq8/bejne.htmlsi=hxcy13v_3UGxeJx9
@@brickandgear cool. Thank you!
Oh like a tank that goes on water hey can you do a dragon that can walk
That would be an interesting build.
Yeah ooh how about if you make it one designed to be a forest dragon that can walk in nature
Is it possible to see underwater with additional camera? I wonder is there a fish or something😂
You should check out the sunken airplane exploration video! Lots of fish there... and an airplane as well...
I would like to see it equipped with better propellers...
I just got a 3D printer for the channel, so expect some 3D printed ones in the future. With proper LEGO axle adaptors!
It looks like this is based on a 40K design?
Could it be my subconscious reaching out to my young gamer days!?
@@brickandgear Oddly enough, I've never played 40k. But I have occasionally thought: "That might be a nice model to build . . ." Mind you, that was back when their models were resin rather than plastic.
5 -. Минус за видео-камеру, которую надо было под водой разместить)))
Just the cocaine transporter I was looking for
😁
The biggest question: do Lego bricks hurt when fish step on them?
They haven't complained so far, so probably not.
bro's cooking
😁
as a kid i always tried to build something like this but didnt had the bricks for it 😢
Can you build it now?
no because im still a Kid 😢 but as i tried to build this i was younger now i have some bricks not all
You'll get there someday!
Belok kanan kk
a tankboat
something tells me that the Mk-III is going to be bigger and badder than this version…
Probably not bigger. Definitely improved, now that I got myself a 3D printer. Custom printed propellers, custom printed buoyancy boxes... Probably custom printed water protection for the motors...
might be more interesting if you talk through the build rather than remain silent
You think? I was aiming for a more ASMR feel with the natural sound of the bricks "clicking" in place.
ещё камеру установить в днище корпуса и снимать морское дно
Это был всего лишь тест, поэтому камера под водой мне не понадобилась.
that's incredible
Thank you! 🙏
Lego suxs now. It's just panels and shit. Hardly even building. Then there's all there woke shit.
