    Thanks! If you mean that it's kind of short here, I know those proportions are a bit off, but I didn't want it sticking out too much and once I had the turntable in that spot, I didn't want to move it forward either because the base/bottom was working out for me well.

    Here's my most recent "quality" build that I couldn't show off for some time: Feature video: Free instructions on Rebrickable: https://rebrickable.com/mocs/MOC-72143/SaperPL/mini-mobile-crane/#details EDIT: The MOC has landed on Build-A-MOC store as a set for purchase: https://buildamoc.com/products/mini-mobile-crane Render: Photos: Drivetrain? I hope you'll like it :) Check out my youtube channel and rebrickable instructions for more small scale stuff like this.

    I did another custom 3d printed piece: This is a small scale, front wheel drive GoKart build made to show off a new custom 3d printed piece that I made. know this is a bit weird construction for a GoKart, but it's meant to be a simple build showing off the steering hub. Also 4WD wasn't really an option without a differential between the front and rear axles as there's slight difference between front and rear axles rotation when turning that causes resistance when doing so. You can download the STL file for print here: https://www.thingiverse.com/thing:4806746/files Please note that with CV-joints instead of standard universal joint, the custom hub could have an axle hole, would hold the wheel more firmly and be a bit more universal. I will revisit this idea when I get some CV joints for testing.

    Thanks! Actually I could do a bit better with less gears and better gear ratio with new differentials. Also for a bigger model you can make neat final drives with gear reduction: For Powered UP it doesn't really matter because the XL motor is just an L motor in disguise. Also if you want to make a relatively small tank model, this means you can fit a third L motor on the other side.

    This is a type of steering for a tracked vehicle that uses so-called subtractor which means input from motor used for steering is subtracted from the main drive input

    Thanks! I did it this way because that's generally the scale I'm used to with my small models, but yeah, it would be cool to have this part in different sizes.

    Pretty cool model - great job. Especially when it's mostly Technic with just some small portions made with system bricks. Steering angle on wheels is a bit small though and the rotation on the turntable seems a bit hard, but I get that you couldn't do much at this specific scale in between big turntable you are using and 90 degree arc gear racks. Anyway really cool mobile crane. I'm going to show off my crane soon at significantly smaller scale - yellow work machines are cool :D

    I made a quick build from some leftovers to test it: I have also created thingiverse account so you can download the custom part files to print without grabcad account. You can find the source files from Solidworks and STL files for printing here: https://www.thingiverse.com/thing:4800409

    Thanks, you'll have to wait a bit till I make a video and finish off instructions, but it's worth it :D I'll share it here as well when I'm ready.

    Back when they did a lot of frame like models with just marking the edges and arcs with flexible parts it was different, but now when they make a model like this that is closed of in most of the places, when they make something like this right at the front, it feels unfinished/unpolished. I mean the connection between wheel arc panel and the curved/angled liftarm.

    Looks interesting, but what bugs me is that for a $149 set, they could've try to plug the holes in the front fenders/wheel arches. Is it just me overestimating the scale of it or is lego taking more and more shortcuts even with their "flagship" sets. Like no diff in Senna?
  12. SaperPL
    This is true when you are using it with longer rods, but here it means when putting this on top of a liftarm, the bals joints would be vertically offset from the plane in between the attachment points of steering arms, so this would distort the steering as being lower would mean the steering links would make wheels come inward when suspension is released and outward when suspension is pressed. The second issue is that 6574 or even this piece would freely move on a forward axis, so while 6574 used with longer rods is okay to move a bit front to back if secured a bit from the front, for a small setup like there's no place in front of it to secure it with something blocking it off. Thanks! Actually I ran out of longer axles for this build and tried to simplify it without hiding the functionality. My previous video shows how overcomplicated it could be. Anyway there is a liftarm 3L positioned vertically where you could mount a longer one or simply you could use 7L axles instead of those 5L with stops to have more connection points. but yeah, I get that, but I got used to the fact that with those small builds, you need to sometimes reinforce the frame with the body above the steering to have a solid construction. If you have any ideas for some custom parts, you can throw those at me, I can try to figure those out for printing. Also you can use Studio's part designer to put together pieces of existing parts by importing pieces from library, shaving them off with eraser from what you don't need and putting them together into a single new part. Using eraser on some technic parts is glitchy, but you can make a point or show what you mean better with those at least.

    Thanks! This more of experience and having some money to sink into specific parts because those small scale builds still require a lot of parts with matching colours. Btw, the instructions for the crane are almost ready, but I want to launch it all together with video. What's not clear on those renders is that it has 6 wheel steering/3 axles so it's 8 x 2, but also has a micro V6 in the middle of the cabin, so it's a pretty cool model to build :) I want to do a full box trailer for the American Semi with some reasonable functionality using two motors because it should look really good. with a full box trailer, but I want to show off the feature that trailer has cables to plug into the tractor, but also the tractor can work standalone. I'll probably make another truck soon, with just slightly bigger wheels, but I need to figure out the rear axles with suspension. I'll be cheating though with 3d prints :P

    I like there's a lot more people building small scale trucks than I would expect. Here's my stuff to join the small scale gang :D (Free instructions on rebrickable here: https://rebrickable.com/mocs/MOC-62325) Original PF version: (Video and instructions coming when I get my good camera back :| ) (just a load test, this kind of trailer is not for a vehicle but rather to have a tall load mounted with a crate on it, the front is not detatchable) (Video and maybe instructions for the trailer as well coming when I get my good camera back :| ) And a weird member of the family: Also this, although this doesn't perfectly fit the "truck" term, but it could be a good base for small RC truck: Subscribe to my channel if you want to see more stuff like this, also non-truck models are there as well :D

    Świetny model, powinieneś się nim i kilkoma innymi pochwalić na Lugpolu :) Ja robię modele z tymi kółkami w zbliżonej skali, tylko z samych technic'ów, ale użycie systemowych klocków pozwala na ładne dopracowanie, to widać w twoich modelach.

    I know this is a bit of heresy, but I've seen some people using various custom parts like tyres, rims, pneumatic actuators etc. This is my attempt at shrinking front axle suspension: I started by shrinking 15459/31794 and 2739a And then I made a liftarm with teeth to replace functionality of 6574 so it doesn't need to lay on system bricks: I need to figure out some kind of neat rear axle to match this, but it feels like I won't be able to have independent rear suspension without making some over the board custom elements and I wouldn't want to go that far. The steering arm and liftarm with gear rack can be found here: https://grabcad.com/library/lego-technic-compatible-front-axle-suspension-parts-1 (I'll try to upload it to thingiverse, someone noted it already that it's better because you don't need to log in to download). I'm re-doing the rod as I used someone else's design from here: https://www.thingiverse.com/thing:3210100 and the connection on the ball is pretty loose. Hopefully this is interesting :)

    Another build in the series, slightly bigger and RC one: Still not perfect, but hopefully the suspension design is at least interesting.

    Thanks, and yes, the control+ technic hub is awesome at being used as structural and shape piece: Thanks! I prefer doing small builds over huge ones where bricks are getting to a point of being pixels. It's more challenging to do some mechanics at this scale as well as making the shape correctly, and on top of that, it's something that more people can do when I make instructions for a model (the semi truck tractor has free instructions on rebrickable btw) Check out my channel for more of those builds and my rebrickable profile for free instructions of some them :)
  19. SaperPL
    Some time ago I've build a minimal scale control+ 8-wheeler. The shape isn't perfect, but I hope it's interesting: I hope you'll find it interesting. Also check out my channel, more cool stuff out there, I promise :)

    I'm prototyping a small scale Dune/Trophy Truck chassis that I want to make instructions for at some point. I got two interesting iterations so far: The first one is buggy-style with rear engine and rubber-band front suspension. the second one is more of a truck, has a front engine and all shock suspension. Additionally I had some interim iteration between those two that I didn't made a video of, but it had some interesting features as well: Gallery for this build: https://imgur.com/a/6umV5zm I'm still not fully satisfied with what I've got so I'll iterate some more on the front suspension and the chassis structure itself before I can make instructions, but I hope you'll find some of the techniques interesting. Also check out my channel, more cool stuff out there, I promise :)

    My tractor MOC got the first review: Make sure to enable auto translated subtitles on youtube since it's a German channel.

    Free instructions for the Powered Up version of this American Semi Tractor available on Rebrickable: https://rebrickable.com/mocs/MOC-62325/SaperPL/mini-rc-american-style-semi-truck/#details
  23. SaperPL
    Thanks! I actually did quite a lot of builds around the idea of spreading the RC across whole set of semi/farm tractor + trailer to cut the scale down. Here's some of more unique examples: Here we have the servo being kept virtually in line with tractor but inside the trailer. The clicking noises are from the use of quite a lot of gears and clutch to transfer the drive. I've learned a lot since that build and could probably make this approach a lot better now. Here's whole RC for the farm tractor in the trailer made possible with single flexible link. Just to show that you can have more than one inputs with a single axle :) I've also had a multiple attempts of putting battery inside the trailer like shown here and in the american semi video.

    Thanks again guys! I'm glad you like it. I get a question though - do you like the roof of the cab in my American Semi? Do you have some ideas that it could be improved? I'm finishing the model in studio right now and I'm trying to find a clean way to make the roof not that tall and without so much gaps.
  25. SaperPL
    Thanks guys! By the way, you can see on my ideas submission page how the platform is broken now - older submissions have issues of the embedded content disappear from the submission description and the support doesn't respond to emails, sometime they fix something, sometime nothing happens. You can have whole additional year after reaching next milestone, but that doesn't matter if your submission description is gutted out of embedded content, especially showcase videos...
