WoW! It looks like 4 studs long, right?

Of course it would work with wheels. Modules with tracks can be easily removed and you can put there whatever wheels will fit. Tracks in this scale were the whole point of creating this MOC. I wanted to build such machine and check if this is reasonable, possible and if it will work on acceptable level.

Hi, I present my newest creation – Jeep Wrangler, but with tracks. It is loosely based on Lego set 42122. I built it mostly because I wanted check if such idea can be done in such small scale. And it looks like it can! Here as usual I tried to do something new. I wanted to check if tracks, small ones, can work in such scale, both from mechanical and off-road capability point of view. Apart from standard features (AWD, full suspension, steering, RC, working engine) I always try to fit into my creations something new. Model has tracks mounted on modules which can move, but in limited range, to avoid full spin. You can see it on the video below, starting from 1:27. I consider this as a nice addition to idea of tracked vehicles and I didn't it in other similar lego models. The rest is standard list of features I mentioned earlier and will list below the video. Hidden into the body of famous Jeep Wrangler. I tried to improve a little shape of original model 42122, but I'm not sure I succeded. Snow on the video is rather hard opponent, so I need to admit that Jeep in such configuration wasn't off-road king. Nonetheless it gave me fun to drive it here and there. Below you can find video and list of features and details. Enjoy. Instructions: LINK General details scale: 1:16 dimensions LxWxH: 29x13,5x15cm weight: 871g Features: RC front axle steering (C+ L motor) RC 4x4 drive (2xC+ L motor) Winch with lock 4-link live axle suspension for all 4 tracks 4 studs ground clearance Openable all doors, tailgate and hood Working V6 engine with fan Detailed front part of the cabin Powered by Buwizz 3.0 but also prepared to be powered by standard C+ Hub Photos: LINK My Jeep Wrangler is powered by Buwizz 3.0, but there is no problem to use standard C+ Lego battery box. You can add it vertically: Or horizontally after small modification of tailgate: Internals of the MOC, so drivetrain connected with V6 engine and steering:

This is nice, more smooth solution than the one with knobs. And it works well. But you need to consider 2 things. First: perfect match of teeths to provide smooth rolling, second: under any circumstances the axle cannot slip out from this setup, even a little. If it does, only a little and small gear skips a tooth, you are toasted. Resistance will be unbearable.

This topic will never die because there will be always delusional people who think they can decide how other people value private time and skill.

My truck has my nick on the back, so I believe it should be pretty easy to say which one is mine :D In case of the model, the successor is based on AM General M818 military truck.

I consider that, but as you mentioned, this is additional weight, which is not welcomed (but manageable) also placing the camera is problematic, since if I put it outside of the truck dimension, it can be impossible to pass the gates without time penalty. Last but not least, I still didn't buy any decent camera for such purposes :D

You need every single Ncm of torque you can get from those two XLs. Below you can see video from LTTC 2024 Competiton 2, where we had Sariel with us, so there is very nice video recording of the competition. It was not as demanding in case of the power of trucks but you can see how LTTC looks like. I was there of course, you can find me on the video, but I drove successor of the Star 266. But the first competition from this year took place I would say in high mountains, so here, torque was more than necessary. I have photo of it, but not video prepared.

It is most probably possible, but current setting is used mostly to get proper gear ratio on drive shaft to have proper, reasonable speed of whole truck.

Hi, I would like to present you my first MOC prepared especially for official LugPOL Truck Trial Championship. MOC is based on very famous, polish truck with good off-road capabilities - Star 266. I choose polish truck to introduce some local technology to the competition dominated by soviet machines. Instructions are free of charge, so if you have parts and some time, you can enjoy off-roading with this model pretty easy. LINK Here are my priorities when designing this truck: to fulfill LugPOL Truck Trial Championship rules and to provide truck which will be accepted by judges to prepare truck with good off-road capabilities to build it to make it recognizable Couple of LTTC rules: scale: 1:12 to 1:14 number and type of axles true to the real machine type of suspension true to the real machine must be RC and all-wheel drive the truck's cabin true to real machine, with roof, seats, steering wheel, floor and with openable doors All above rules were fulfilled, below there are couple of more details: scale: 1:12 drive: 2x PF XLs coupled, if necessary, each wheel can harness power of two XL motors steering: PF L motor weight: ~1990g dimensions: W x L x H: 25 x 64,5 x 32,5 studs (width without wheels and tires) Star is powered by Buwizz 2.0, but since it uses only PF motors in very simple configuration, it can be powered by anything you have Truck was designed to work with 96mm Tamiya CC01 tires, and those tires you will see on the video. But in the instruction I used the closest in case of size official Lego tires. You can of course put bigger tires, like Lego tractor tires: 107mm, but some rubbing during extreme off-roading is possible. Couple words on the truck itself: Star 266 took part in two competitions in 2023, so it is well tested, any minor issues were eliminated and I'm convinced, that it can be used in hard terrain without any worries. It is rather simple construction, to reduce the weight. Details are there mostly to be able to fulfill competitions requirements. The truck is the mix of many ideas I had during designing and I wanted to test during proper, official competitions. Some of them proved to be hard terrain effective, some of them, not. So this is for sure not the ideal trial truck. But it is not afraid of outdoor obstacles, mud, dirt, stones etc. Pros of Star 266: high ground clearance (7 studs with 96mm tires) high approach, break over and departure angles highly response suspension with long travel to fast and precise surface adaptation each axle is connected directly to coupled 2 PF XL motors, which allows to stable, equal speed of all wheels and provides (when needed) all available power for the wheel which needs it the most steering is done with PF L motor for speed and strength, possible steering angles are > 45 degrees per site Cons of Star 266: turntables used in each wheel introduce friction, quite a lot of it, I highly recommend to try to reduced it as much as possible (I advise to use a bit of sanding or lubrication, or both) due to lack of any shock absorption, stability is only on decent level truck's cabin shape and location is not the best in case easy passing the gates during competition, but this is my personal opinion Internals of the MOC, so drivetrain and steering with motor on front axle More photos: https://bricksafe.com/pages/keymaker/trial-truck-star-266

I do not build sport cars, but still, those tires are interesting. Do those tires fit for standard lego rims? I mean the smaller ones, so for 1:10 scale models.

Lights are no problem, they are available in Control+ system for some time already, but in case of speed? No, I don't think we'll see here anything new in case of motors.

Very impressive model. You have put some many details in this scale.

@Appie thank you for kind words. I'm glad that my MOC were useful for some people :) Those words give me motivation to go back to MOCing, since I have couple of unfinished projects on my shelf still waiting due to some changes in my personal life.

Great idea, I wish to be part of it.

Beautiful and very detailed model, just WoW!

Lego is proven to last for decades. But if I'm not mistaken and I can also see this in newer Lego sets, they started to use different kind of plastic, some plant based? And now I'm not so sure if this new kind of plastic is as durable as the old one. And in case of Cada? Who knows, company is rather young (started at 2016), so there is no valid data about its durability.

I will say again, it is beautiful model. For sure I check this one more deeply when I will start building my version of this Mercedes truck, in RC version of course.

I planned to buy this one because of gears. But now, I will buy it for this part. It gonna be very useful.

I really like solution used in front and rear axle, the minimalism which is behind it. Also rims from Camaro plus RC tires, size 54 or 56mm, right? Great addition to overall very nice look.

Yes. RC tires for 1" rims are designed for ~25mm rims, but they play well with 30mm lego rims (20mm wide). I bought 58mm and 62mm tires, They all look great. If you chose some smaller ones, then I believe 30mm lego rim (14mm wide) will be useful too. "Super Swamper" tires you can find here: https://www.aliexpress.com/item/1005005384136434.html?spm=a2g0o.order_list.order_list_main.4.4ac61802WZdgaE But I don't like their tire pattern. I bought variant B. I see them in mini MAZ 537 or in general, small trucks.

I bought couple types of tires for 30mm lego rims, all are good, but those (the most expensive I bought) from INJORA... https://www.aliexpress.com/item/1005005579629547.html?spm=a2g0o.order_list.order_list_main.10.4ac61802WZdgaE I am absolutely amazed by them. I do not regret a single PLN on those. They are sticky, super softy, with great pattern and overall very high quality. I cannot wait to build a crawler with them.

Thank you so much. This is what I was looking for. I prefer this small scale and my goal is to build capable crawler in this size. And lego tires are not enough to do it properly.

Hello, does anybody know where I can buy third party tires for 30mm Lego rims? Something like on video below? (I couldn't figure out the proper link to shop or something based on this video).

@Fluwoeb I think it will work if not high torque applied. But just in case, you may be interested ;) LINK
