As promised, I have uploaded instructions for the updates Mack Marble Trial Truck. You may find them for free at Rebrickable.com. The MOC uses Power Functions, which I understand is a little outdated, but it still works well. Maybe for the next update, and I'll change it to Control+. The truck features: Four wheel drive with fixed differentials Front steering Front and rear live axles Front and rear portal axles Power Functions XL for drive Power Functions M for steering Final drive ratio of 1:2.79, and can be changed to 1:5.01 by changing the portal axles. The underside of the truck. And here is the original, which was one of my first instructions on Rebrickable! I personally like the updated version a little more.

Tipping Dump Truck 462 pcs | $49.99 Looks pretty good to me.

Thanks again. I think when I was building the prioritized the use of the 4L stop axles to lock the gears in the differential. In retrospect, there may have been a better option. Yeah, the axles don't pop out. Agreed, the open differentials are made for general household driving. It quickly became clear this truck had no place in the trial competition for many reasons (C+ interface, high COG, small tires).

It's my jam. I feel like I am the only person alive who still builds from a single pile of bricks.

OK, the first of the above trial trucks are available with free instructions. You may find the instructions at Rebrickable.com. It's been a while since I have made a motorized MOC, and this is the first one with Control+. I hope you enjoy, and find the instructions clear. The truck features steering, four wheel drive, and front and rear live axle suspension. It can be driven using LEGO set 42160 Control+ Application. Posting this image makes me think it been a long time since I posted the bottom shot of a MOC. And sorry, I don't have any footage of this truck driving around at our local Truck Trial event. I'll post the updated Mack Marble soon.

This keeps looking better to me, but I just can't get on board with the winglets of these newer bikes. They're funny to my eyes.

It's crazy how another day of information can change the tone on a set. It looks like the set has a lot of new parts that are interesting to me; the pistons, the wishbones, the panels. Also, it looks like the steering link is a different length than we have had in the past (maybe 7, 8). Yeah, it agree. I find the new system to be not very smooth. There is a reason the old engine blocks have been around for a while. They do work well.

Where do you see that part?

Yeah, I agree. Also, it seems to make sense that they would like to release the most up to date version of their top of the line bike.

Great job @gyenesvi! It has a fun look. I love the shaping of the grill, and the old headlight parts are a great addition. Technically, the drivetrain looks very good. I have never tried the leaf spring idea, but I keep seeing them in great builds, so I may need to try them out. Thanks for sharing.

Great job on this @nico71. I have fond memories of a little Del Sol when I was younger, and your managed to get the look and feel of the car very well. I love the removeable engine. This is such a silly feature, but I love it when it can be done. Keep up the good work.

Hmm, I have been on the fence about getting one of these 1:5 motorcycles, but I'm a Ducati fan. I'll wait until we have little more information before making a decision, but I'm interested. I liked the functions of the Yamaha, but the blue wheels look funny to my eyes.

The Mack Marble was a fictional truck that I came up with years ago. It's not based on a real truck, so it was my attempt at coming up with a fun name. This truck uses the 107mm tire from 42099/42070. Correct, the smaller DBG truck is using the Zetros tires.

This past weekend I had a chance to participate in my first truck trial. I know, I know, I'm about 15 years late to the party. I brought the Mack Marble (Rebrickable Instructions), a truck that I designed about 12 years ago. It worked well enough. But it turns out that some of the trial truck design features that were settled years ago were missing in my truck. So the open differentials, non-braced steering system, and one non-braced drive gear caused some problems. But other than the that the truck was stable and had good speed and maneuverability. I'll make some updates to the truck, and share them soon. I do love an orange truck, but the red looks pretty good here. Here is a photo of all our trucks. The little DBG truck is mine as well, but it was too small for our course. I'll post that truck soon as well. I hope to do this again soon.

Looks great. I can't tell, is there suspension on the rear two axles?

I would like it too. I'm still surprised a non-printed version is still outstanding. Also, while we are making requests, does anyone have Part 5713?

Thanks, yeah it's a simple feature that adds some playability. Thanks for the comment, and I'm glad you noticed and liked all the features in this build.

Sorry I missed this earlier. This MOC is great; the old Russian truck look is spot on. And any MOC in Dark Azure gets my vote. Also I love the way the front fenders are made. Thanks for sharing.

Thanks for the comment. I spent more time on the hood than is healthy. I'm happy it turned out. I like the brush as well, so I'm glad it resonates with you too. Thanks again. Yep, it's tiny. No, the Green U90 has been turned into other builds. Yeah, it's about half the size. Yeah, people keep asking for the U406, so I'll add it into the queue. I think I have an idea for the hood, but I'll need to decide what to do about tires/driveline etc. Yeah, I just spent some time reading about the U401, so I think it would be a good way to honor the project by doing that one too. It seems like a simple design, but it will be super small. We'll see if any functions remain. Thanks! I usually disassemble my builds, but I have a hard time taking these apart, so the lineup allows for some fun photos. Thanks for the comment. Yeah, the U90 is not the most loved, but I like it a lot. I'll wear my decision with pride. I'm happy the functionality all came together.

Keep going! This project is great, and keeps getting better.

I couple of years ago, to celebrate my 100th MOC on Rebrickable, I designed a 1:21 scale Unimog U423, and a number of attachments. The project was well received, and one of my favorites of the last couple of years. I enjoy Unimogs a lot, and so when one Unimog MOC is well received, it encourages me to build more. I continued with the U4000, and the U90, the later still adorns my shelf at home. So I wanted to keep this theme going, and see what else I could design. The Unimog U90 (408) is a favorite of mine. It's just the right amount of weird due to it's quirky design. The hood shape is iconic, and the I5 engine is also a little strange. I love it. In keeping the 1:21ish scale of the design, the truck needed to be narrower, by a lot. The scale calls for about 11 studs wide, compared to the 15 stud wide U423. After playing with this, I decided this is too narrow as the drivetrain would be lame. I settled on 13 studs wide, and quickly decided on the narrow 49mm tires. The tread is not great, but it allows for the U90 to be just a little smaller. The chassis came together pretty quickly, but the front quickly became a problem. I generally build in Studio when the real brick design is done, but I needed some help so I did some early Studio drafts. The engine got in the way of the hood, and the hood got in the way of the front mounting plate. And the bumper didn't work. Many iterations and drafts kept moving different hard points: steering linkage moved, engine moved front to back, the frame was adjusted, 9 bumpers were tried. Eventually, about a month ago, the design just popped into place. The hood came together, and the rest finished up nicely. The final design features the following: Steering with HOG Rear wheel drive with portal axle Rear pendular suspension I5 fake engine Opening hood Opening doors Tipping bed with tailgate Front mounting plate for attachments: Brush Winch Plow Rear hitch I'm partial to the brush. The engine works well, and just clears the hood. Just a little bit of suspension. The cab is just a little too short front to back to my eyes, but this is where it settled. The bed does tip, but only in one direction on this MOC. And I had to get on photo of the currently built MOGs together. I realizing the U4000 needed to be a different color. As always, instructions are available at Rebrickable.com. And a little video below to see the functions (and my poor editing abilities). Like the Thirdwigg Farm, I'm not sure when this little theme will end, as I still have a lot of enthusiasm for this series, so if you have another suggestion to add, let me know. Right now the consensus is building toward a U406. Considering this was my first MOC on Rebrickable (MOC 164!), it may be time to update it. Again, I hope you all enjoy.

Sorry to bump this old thread, but when I present at shows, the John Deere 6130R is one of the favorites. So I tend to keep it built to bring it along. This year for a show I decided to bring it with, but it needed a new addition. So I built a dump trailer. Features: Dumping bed Linked tailgate Four wheel suspension Free instructions for both the tractor and the trailer are at Rebrickable.com. Just enough suspension. And a little video to show the functions. I hope you all enjoy!

The last two shows I went to I let some children play with my builds. It was great to see the joy in their faces as they got to touch something when everyone else expected them to not touch anything. Some adults did this as well, and were grateful for the interaction and led to some great conversations. It gave me some great feedback on the strength of the MOC. More crucially, it helped me watch if they found the play features, how they found the features without instruction, and if the feature was at all valuable to their play. Some things needed to be fixed, but for the most part there were no issues. I tend to have a low concern for damage as most of the issues can be fixed quickly. There was no significant damage because most people assume what they are handling is very fragile.

I was moving a little too quickly while building, and missed this while photographing. I was replaced with Black 3L pin with Stop (32054) in the instructions. You are correct. Yes, this assembly could pull out, but not before the grabber drops the load. They have little grabbing power, so the connector assembly is the least of the concern here.

For those of you interested, I completed instructions for the Tipper Truck. You may find them at Rebrickable.com. Now I can take it apart, and see if I can finish the Hook Lift version. We'll see, my motivation for the other truck is pretty low now.
