As a motorcycle rider and enthusiast, I like building bikes. I figured the closest thing to a motorcycle that has tracks is a snowmobile, so that's what I went for. I want it large enough to use good old PF, for added RC fun. First iteration for the front: Compact enough, but the skis lack a degree of liberty. Second iteration: Now I'm looking into the tracks. Snowmobile track suspension system is a lot less trivial than it looks: I'm not sure I'll replicate all the subtleties, because it involves a compact torsion spring which simply does not exist in the Technic world. My third iteration on the tracks suspension is a basic parallelogram, so I'm still unhappy: And that's the status for now. -
Good day, everyone! Each winter I hope to build some offroader to drive in snow, and each winter something goes off. Finally in 2022 I,ve finally built what I wanted - big orange snowmobile with control+ electrics and sprockets from Liebherr/ SNOWMOBILE "TRIDENT" Two main parts are the chassis and the body. Let's start with former. Front side - as it is snowmobile it is fitted with two steerable skis. Suspension consists of parallel levers with two big yellow shock absobers and two hard small shock absorbers between the levers. Suspension is strong enough to bear the weigh of control+ smart hub with 6 battries, body parts and optionally Darth Vader as the driver. Skis are 5M wide and each one has two small rubber wheels inside to add traction on smooth surfaces (with them you can steer even on smooth floor - without only on snow) front suspension has positive castor angle. Which looks cool, but required some tricky techniques to implement steering - for example - for steering I used Large Angular Motor (or simply LAM) it is in parallel with suspension levers, but connected to chassis and smarthub with angle. Next - rear part - all driving motors (2 XL) are inside the tracks. Reduction gear is 28:36 (or 1:1,29) - keeping motors inside the tracks reduces the weigh of body which is good for suspension travel. Long shock absorbers work for vertical movement of only rear part of vehicle, whereas short sh.a. are used for vertical movemnet of whole body (long sh.a. act as parallel levers) And finally - the bodywork. I think this is for now the best bodywork I've ever made for MOC - it is orange, it looks good and its reliable and rigid enough so you can grab this Snowmobile by most of it's orange sections and nothing will fall away. Furthermore, all panel are locked in places and don't wiggle at all. I've even used aquaman's trident from brickhead as mascot when I figured out that Snowmobile looks a lot like trident from above. For everything else that you need to know i invite you to watch the video: P.S. I wanted this snowmobile to look loke a fish. But it turned out to be closer to shrimp or prawn :) -
I' ve made a model of a Snowmobile. I've tried to make it as detailed as possible. Video: Functions: - Driven tracks (L motor) - Steered skids linked to handlebar with Ackermann geometry and positive caster angle (M motor) - Front double wishbone suspension - Realistic rear suspension Everything is controlled remotely using SBrick. Please watch the video to see this machine in action and for more details. I hope you liked this model. -
I´ve never been the biggest fan of oversized motorcycles in Lego sets (i´m looking at you, various Ninjago sets and especially 2019 Captain America Cycle!) so i decided to shake things up a bit and reimagine the weird bike/snowmobile thingy from the recent Ninjago set 70667 into some sort of hotrodded Ice Trike. I tried using most of the parts that are characteristic to the original build and/or get stickers. What do you think of this remoddeling? Better or worse than the original? -
EDIT: Building instructions available: HERE -------- I always wanted to build something different. Something not seen too much on EB. Introducing my latest MOC: Snowmobile With SBrick. Inspiration About two years ago I saw a video about Ski-Doo snowmobiles on YouTube. I really like the exterior design of its product and thought maybe I could build one in LEGO. But I wasn’t skilled enough to finish it at that time so the project got suspended for a long time. This finished MOC is not based on a specific model of Ski-Doo. It’s more like a combination of all my favorite parts from several models with my own thoughts blent in. Challenge: External Design Unlike most conventional wheeled vehicles, a snowmobile usually has a more complex bodywork (except for supercars). Considering its relatively small size, it’s even more difficult to recreate its aesthetics authentically. Some “illegal” connections are inevitable. Challenge: Internal Design An unconventional vehicle needs an unconventional framework. Here is a screenshot from LDD showcasing the frame. Servo Motor is used as part of the structure. Another problem goes to Power Functions. How do I stack them inside the frame? Here is a cross section view of the model: 2 L Motors geared 3:5 for propulsion. 2 pairs of LEDs utilized for headlights and taillights. Space is very limited, I have to use a pair of tweezers to tuck those cables. Performance Let’s take a look at a video: On hard snows it works fine for most of the time. Also, front suspension responds quite well. Compromises Due to aesthetics concern, Power Function parts were located at the front, which makes the model a bit front-heavy, resulting a relatively poor traction. I wouldn’t dare try testing it on soft snow... Also, the color scheme is a bummer. The white one is imperfect. Black one looks much better, but a bit dull. I still haven’t decided which color should I choose to make building instructions for... Last But Not Least This is a little off-topic talk: I just got to know about the Chinese company “LEPIN” and those dirty things they’ve done recently. As one of the very few Mainland China users on Eurobricks myself, I feel sorry for what my fellow people have done to this world. I feel sorry for Madoka. The only thing I can do is to share my original works with you guys, That’s the least I can contribute to this fantastic community. Anyway, so much for the sentiment. Hope you enjoy this MOC and stay tuned for the instructions. -
Good day! Today I present to you my newest MOC - a Snowmobile! This MOC uses my Heavy Duty Track cocept , which looks to perform really well on carpet. There's not much to tell , it is under-powered by 2 m-motors and steering by another m-motor. The drive motors can be changed to l-motors without any problems , it should perform much better with them. There's no snow where I live , so I wasn't able to test it outside Here's the LDD file ( click! ) and Bricksafe gallery Any remarks or opinions are welcome -
Hey guys! As i've anounced you some days ago, i made a brand new snowmobile wich totally kicks the hell out of the MK I i made two years ago... This is lighter, faster, nicer and mainly better built than the previous one :D I wanted to shoot the video before posting it, but i'm not sure there will be snow tomorrow on the mountain where i'm going to shoot it... so for now here come the pics and i'll cross fingers that i won't make 50km uselessly :D Features: - Power functions - Front independent suspensions - Rear track suspensions - Rc buggy motor for drive and servo for steering - Improved track thread - Custom stickers you can see how i improved the track by adding 1x1 rounded plates in each hole of the threads, now it has way more grip also because i moved backwards the center of mass placing the lipo battery under the seat. In theory it should avoid the front skiis to sink in the snow... the rear suspension also helps pushing the thread against the ground... It performs really nicely on the carpet...but i think it will be fine on the snow too :P there's a lot of ground clearance so it could easily deal with 2 or 3 cm of fresh snow. Front suspension is really soft so it should be stable if one of the skis goes on a bump. as you can see in this picture i've removed every atachment that sticked out of the track and the skis to avoid a braking effect once it's in the snow.. I also placed all the electric components quite high so the snow dragged by the track shouldn't reach 'em detail of the track with 1x1 rounded plates :) i hope you'll like it :)

Hi all, I'm about to disappear for several months, but before I go I'd like to leave something here for your amusement... and hopefully get some advice It all started with , best one I've seen so far. I wanted to do something similar, preferrably with a softer rear suspension that would behave realistically on a bumpy ride (piterx setup seems stiff). Trouble was, I had no clue how these work. I had to like a gazillion times, to finally make sense out of photos and other models. In the end, I think I got a reasonable setup, using custom shocks also inspired by piterx Ford Fiesta. Now, for the fun part: I'm new to snow. I grew up in Tenerife, where you'd only ever see snow when it was old, unless snow caught you by surprise above 2,000 m. and then you'd be stuck there for days. No kidding, my dad used to work in the telescopes up there, when it snows there, you better not be there. And I never travelled much. So I'm utterly clueless about the different states / kinds of snow, let alone which ones are good or bad for what. I just took my protoype for a quick ride in the only moment I had a chance. The result is rather embarrasing, but I hope you find it amusing: I guess snow was too soft.. how should it be to ride a Lego snowmobile this size? And what weight would be reasonable for the model? Should I first build a snowgroomer and use it to prepare snow for the snowmobile? Some improvements I've been thinking of (but not sure they're good ideas): Longer, wider (4L) skies, specially at the front. Longer suspension arms (6-7L), to separate skies for better sidewise stability. Move weight to the rear, for better traction on the tracks. Center weight sidewise, this prototype was always leaning towards the right. Reduce weight, this prototype was already ~700 g. without any bodywork! Use outer output from Buggy motors, which is stronger. If you're curious about the targeted aesthetics, it'd be something like this: And if anyone knows the physics behind , I have an itching curiosity: how light should a snowmobile should be to be able to ride on water with the inner (fast) output of 2 buggy motors? (my guess is: lighter than the motors plus a PP3 9V battery) -
Review - Snowmobile 'Ello all Recently purchased the snowmobile, and wish to try my hand at this reviewing lark. It costs £14.99, and for non teadrinkers, USD $19.99 and EUR €14.99. This set appeals to me greatly, due to the plethora of interesting peices, and great angular design. Not to forget, those tracked peices too, especially as these are the first in my collection. Nonetheless, does it provide a nice set of skids for your quids? Let's find out! The box Here's the box, quite small, with a nice image of the set. Well presented so far - Shows suspension function in the corner Ashens fans will be relatively amused, 0-3 sad onions here! (Not the rare 0-8 we seldom see) Contents Out of the box came three polybags, one for tracks, one for small nitbits, and other for main elements - exciting bits can be seen already! Comes with instructions for A and B model, which is always great - to TLG for that. Upon opening the bags, we see some great pieces, new suspension arms that are compatible with this new small steering knob, and the larger one, making it great for all scales of vehicle. There's also a connector with the two cross axle holes coming out of it, as depicted as Hrafn's forum avatar - very useful piece. additionally, the dog bone I frame, another useful piece. But, most importantly for me, 6 of the thin 4x2 plates in black - I've always wanted a pair of those! The steering link here comes with no stoppers, which is always useful - especially after building Kuipers' pony car, which uses both sides. Not to forget the 3l pin with cross axle, which this set has 2 of! The Build Instructions are well laid out, had no issue distinguishing colours, although some steps were very simplified. We begin making the suspension assembly, with a clever use of the I frame. Turning radius is a little short, however. Another instruction shot, however I've highlighted the frictionless pin there, as I've perused the instructions with great effort, and haven't found anything that connects to it. If anyone does fathom its purpose, let me know Cool technique is used here, hat goes off ! Leftovers . Completed Model The finished model stands proudly on the desk, after about half an hour of building, helped along by some 80's rock, and a good cup of tea, it's looking great. Especially love the colour scheme of the black on green, and those angles are truly astounding. Note the pin on the L beam that stops the track from tipping up when being held, and the white gives it that sporty look. Great model! Stickers do compliment the model, but I found it looked great without too. They won't be staying on for long, however, as I have plans to use the panels! Front looks very 'gnarly' , and the suspension is plush, and fun to compress - also note that the chassis does not hit the ground when the spring bottoms out! The skids themselves feel a bit wobbly, but they do not come apart easily - those red pins were a bugger to get in, and I don't look forward to getting them out Track rolls freely, and satisfyingly, as well as being nigh on impossible to derail. steering lacks a bit on a hard surface like my desk, however, it's a lot better on the carpet. I doubt next year will bring any snow to test this on either, us Essex folk never have any luck with that The Verdict The functions of the set work perfectly for the price you pay, which isn't big! IT looks great, feels great in the hand, has great pieces that can be used for MOCs. So hats off to designer Mike Jeppeson! PROS Suspension Steering Great aesthetics Good colour scheme No STAMP CONS Could have had a few more functions Playability is limited on hard surfaces Skids are a tad flimsy Design 8.5/10 Looks absolutely stunning Build process 7.5/10 Nothing interesting, but not much repetition Functions 8/10 Functions work well, however there is a lot of empty space in the model Playability 7/10 Works wonders on carpet, but hard surfaces not so much, which could be a drawback for some Parts 9.5/10 Spectacular part selection Value for money 8.5/10 You get a good set of skids for your quids Total: 8/10 Cheers for reading, and apologies for not including a poll - I haven't got the ability to do so (if any staff could add one on, I'd be extremely thankful) This is my first review, so tips are greatly welcome! Also, if anyone found the reason for that frictionless pin, do share with us! Cheers again, Enderman
