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.

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...

Thanks. I've got some more builds at this scale. I'm really fond of those small wheels. I recommend building this MOC of mine which has free instructions made already: Also check out my channel if you like such simple videos showing off various mechanisms and tricks with Technics. I'm not really good with video capture and post-processing yet, but will get there at some point. For now I try to make something cool once in awhile - no schedule, but I had a lot of time recently to do it, so videos were pretty frequent. I don't do model-team approach yet, but I plan on making Cyber Cruiser-chassis based chassis for a model team approach for such small scale builds so you'll be able to connect bricks easily to it. Haven't started yet, so I can't promising anything, but I have high hopes for this. Back to the American Semi - I'll start making the model in studio for this semi truck instructions soon since I've figured out how to build the front in a clean way. I plan on making a trailer as well, but I'm not sure if it'll be one with some mechanisation this time or a simple box one. Mechanised one sounds pretty cool and I have motors and I have a way to handle cables, but that means using big turntable and messing around when connecting the trailer so I'm not sure if that's optimal approach. Without those motors connected, I should be able to make some kind of neat fifth wheel and also for the ideas submission, more motors doesn't always mean better product. Simple box trailer that has proper quality/detailing might be better than something with motorised functionali that gets overcomplicated and shows motors through the sides. And yeah, this ramp design is pretty cool and doesn't necessarily need to be motorised: I've made one version where it was just spring-snapping in place: For this model: Generally go check my Ideas submissions and / or my videos if you like small RC (or manual) builds at this scale.

The core of this concept is the possibility of using Technic elements to build a small farm tractor that can be manually driven with a knob on the roof, but has drive and steering axles routed to front and back for attachments like a trailer with Powered Up motors and Technic Hub for RC control of the whole set.

Once again, if you like this model, please support it on Lego Ideas here: https://ideas.lego.com/projects/73813e70-ae06-4f20-8b52-433806afc765 , it's the first time that I see I might have a chance to push this further since the submission was featured in newsletter. I often see those featured in the newsletter selected as staff picks if they do gather support fast, and I've got over 200 supports in few days thanks to the feature in newsletter.

Some newer videos: Instructions coming soon for free on Rebrickable. Please support my submission on Ideas if you like it: https://ideas.lego.com/projects/5723b2c0-d393-4519-aa23-3012be24bf94

I hate doing rear view mirror supports on trucks and other machines where they have to stand out to the sides from the roof. They always end up either to straight or precisely shaped but easy to disfigure.

Is there a restriction or recommended dimensions for the bike? What about making a studio project for the renders and building a prototype that shows working functionality if I don't want to buy specific bricks in valid colours as long as the model has parts in existing colours?

Well, yes, but not fully. The gears are there because without them the mechanism gets stuck at the ends of the range and going back needs increased force and thus it's not linear motion to get back to center from fully turning wheels. That's the reasoning.

I'm assuming you are talking about the forklift steering? Because the small scale one is just variation of what is there on the previous page, just with slightly different approach. There was a guy that did this kind of forklift steering in a land rover B/C-model, but he had the drive on those wheels and he made it more real like because of that. In my forklift it's probably impossible to put drive in this specific configuration of steering, but take a look at my different prototype: https://imgur.com/a/y6Vlkp8 The project was a mild failure because the PF servo is not a real servo in context of returning to centre under load and having multiple specific angles of turn. But I'll get back to this project at some point with PoweredUP motors as these are actually working like real servos.

So the buggy has this new piece. This opens up so many possibilities IMO. Hopefully those will start coming in all lengths and maybe even the angled ones will be with this design.

Here are my approaches to this problem. There were better constructions on the previous page with gifs, but depending on your model construction this may be useful as well: Thanks guys for digging up this topic though, the previous page is pure gold.

Free instructions are now available on rebrickable

Made a suspension mod to the black unit:

Not sure if it counts, but I made a mini scale (30.4 wheels) suspension for a supercar with mini piston engine and full differential. Pendular axles suspended on mini rubber bands:

I'll try to open it up and make photos of the suspension units from the inside. The idea behind the front steering column is simple: put a 6641 clutch lever on top of the small turn table (between its mounting points) and lock it up with three 6536 pieces to the top of the turn table and 3L axle. All the rest is figuring out how long axle you want to put inside, how to attach rubber bands and how big wheel you want to use.

Made red variant yesterday:

So I did a thing to test out whether a specific kind of independent suspension with drive would work: The build features: - 8 wheels with rubber band suspension - 4 front wheels steering on small turntables - 4 rear wheels driven through knees with cogs - triple differential setup with one differential per rear axle plus one differential combining them together - inline 8-cylinder fake mini piston engine between the front wheels The build is a pretty dirty build made with leftovers from my two cyber cruiser units, so it's more about the suspension than the externals.

This looks amazing. And it's a b-model. I also like the idea to pick up a build and re-use a lot of the construction. I assume the seats are also taken from the original build?

It blows my mind that this isn't even in the top 10 of the contest results...

Suicide doors opening to the sides and then to the back, hard edge of the front and not much proper view from the driver's seat (assumed autopilot or some cameras and screens on the inside). It felt to me like some of those cars you see in sci-fi/cyberpunk-ish dystopian movies and anime. Not entirely different from our current cars, but more simplified shapes.

Thanks! Not a chance to fit suspension in that. Actually I'm tinkering right now with suspension for a build at this scale (using those wheels) and even a truck, and it's terrible xD Thanks!

Hello everyone I want to show off my recent small scale build. The model uses 30.4x14 wheels, has Mini Piston V10 with a full size differential which needed to be shifted due to the size of differential body gear being more than the size of the wheels, working steering wheel and a knob on the roof, opening doors and fairly detailed interior and finally open'able engine cover. You can see detailed explanation on ideas platform (please support if you like it): https://ideas.lego.com/projects/2640e770-47e9-4c84-a68b-81578f7208dc Here's how the engine sounds: I'm going to build a red version this week as well. If there's enough interest on the ideas platform, I'll try to figure out how to release instructions. Also if you have any ideas on how to improve the body, especially the front lights and bumper, feel free to hit me with your ideas :)

Don't go with black if you can. Black is easy to hide black studs and may be treated as such. Also other colours will show the details better, I think. And of course with wrangler, there's that contrast part with black pieces.
