Hello all!

It's been a while, I posted here anything, but now I'll try to upload my works more recently. I start with this Unimog 401, which is the oldest Unimog with Merecdes-Benz star. This one has also an "Ochsenkopf" (ox head) in the hood, which was later removed in the next generations.

The building time took about 2 weeks at all, and this is my first model which got the special dark green color, to get close to the original's painting. I ordered several types of these bricks, more models will come in this color. :classic:

I chosed for building the 1:7 scale, with the 108 mm RC4WD rock crusher XT wheels. They aren't Lego, but as far as I can see nowadays it's normal in tyres, and the look is better imho with these.

Goals:

Llooking and working authentically, as close as possible to the real thing, beside of off-road capabilities and remote control.

Main functions:

Motorized: driving, steering, gear change

Automatic: steering wheel, piston engine, PTO in front and rear

Manual functions: openable hood, doors, rear side

Working:

One Lego PF L motor drives, one M steers. The 2 speed linear gearbox is operated by a M motor. Steering wheel and suspension also works. The original has rigid axles with torque tubes, so I chosed also them. Four of 8466's springs were taken apart, so I got 4 coil springs to get the authentical look in machinery of axles. I also attached differential imitating disks. The rear view mirrors work a little. One L motor drives the whole thing, it's sliding in two axles, because of the 2 speed (1:3 and 1:1 ratios) linear gearbox. This way there is no need for driveshaft length adjuster between the driving motor, and the incoming axle of the gearbox, but the rear PTO has one from 6 holed pulleys. There is a PTO also in the front with a pulley, like in the original. The working L4 piston engine has mini pistons from 2L axles and half bushes.

Details:

I wanted to build as details as possible both inside and outside, like: detailed interior, steering wheel, stickers (for instruments too), gear change levers in the cab, handbrake lever, mudguards seen from inside, fuel tank, number plates, lights, seats, rear wood cover, detailed engine room, tanks for brake, exhaust, etc.

Pictures

I made it in the winter season, that's why you can see snow as background:

There are anti-roll bars to prevent rolling, the vertical 6L links connect them with the axles:

Of course I made a video, too:

Hope you like it. :wink::classic:

Amazing how one L motor can propel this thing! :)

It looks gorgeously! Dark green is great here.

Body looks a bit fragile. But it holds very well in the video.

Looks awesome and it's dark green :thumbup: The color fits very well with this Unimog type. Nice that all the functions it should have are there. I like the steering wheel. Nice solution.

Stunning.

I love the look of the Dark Green, and the details: under the hood, in the cabin, the steering wheel, the grille, the bumpers and PTO's! Very well done indeed.

UNIversal MOtor Geraet. Yes yes. I like this maschine so much. And yes you nailed it. Wow wow wow.

This is a great build! The looks are so cool and realistic. Your color choice is astonishing, really well chosen! It surprises me too that a single L motor is enough to get this model driving...what is the secret? :-)

Thanks all the kind words. :classic:

About L motor.. yes, it's worth to choose for drive. Nearly as powerful as XL motor (we know the numbers), but much smaller. I needed a relatively small, fast and strong driving motor. Because it's sliding, and there is really no additinal space, I can use only one. At least this number is more realistic.

Impressive! Hard to believe an L-motor is driving that thing! What gear ratio did you use for it to work?
The ratio is 1:5 in the axle, and the gearbox has 1:3 and 1:1. So final ratios are the following: 1:15 in first gear, 1:5 in second. As you can see, 15 times reduction is enough to crawl through obstacles, but it's not a trial truck, too heavy and weak for a hard trial stage.
It surprises me too that a single L motor is enough to get this model driving...what is the secret? :-)
Only 3 gears. :wink: --> as efficient drivetrain as possible in this model. And big gears, they are more efficient than small ones. I don't think I told any new things. :classic:

Amazing! On the first look I thought it was a metal die cast model you took for inspiration.

Hello all!

It's been a while, I posted here anything, but now I'll try to upload my works more recently.

Yes, please find more time to build and post your models :laugh: :laugh: - just joking but only partly. This build is a joy to look at. I love the engine compartment and the underside. Even the rear axle looks real from looking at the behind of the truck. Very well built. I know the scaling is different, so the new Xerion tires would not work for this model, but it the scaling were different it would be interesting to see what the model would look like with such tires. The real 'mog has much narrower tires....I expect a lot of builds to come out like this one but at a different scale and with the new tires when the Xerion comes out.

An absolute beauty :wub: .

All details and collor are spot on :thumbup: :thumbup:

Thanks again guys. :grin: I got a massive amount of these dkgreen bricks, more mocs will come including these. First of all off-roaders, military vehicles. I'm also planning to make more mocs with trans clear windshield.

I know the scaling is different, so the new Xerion tires would not work for this model, but it the scaling were different it would be interesting to see what the model would look like with such tires.
This idea worth a try, if I build a vehicle again with narrow tyres, I'll try. What I don't like in the Xerion tyres, that's the shiny surface, the hard material. I know, nowadays its normal, but in this set it's more visible, at least for me. I really hope, TLC will bring back those good old rubber material tyres.

Great work, the amount of details in this truck is amazing, it looks just like the real thing. I love it's performance as well, crawling like a pro :)

Great MOC! :thumbup: :thumbup:

Aesthetically is stunning...just one L motor? Unbelievable! :laugh: :laugh:

You impress me ! not the prettiest thing but a similar remark can be made for the original ( allthough I can imagine how annoying the front wheel fenders must be , to readjust after every little knock ;) )

Thanks. :laugh: Well.. those fenders are surprisingly stable, I don't even remember I had to adjust them during the tests, ride.

I like to build unique/famous/legendary vehicles, and imho it's much more like that than any of today's production cars, off-roaders.

Hi Tamas, finally the right place for your Mog  and is absolute great scaled model.:thumbup:

Glad you like it. :classic: Among my plans is the much smaller version of Unimog 401, once it will be built. I developed a really narrow rim + tyre combination which works in smaller scale, and has the required look.

Tamas,

as Unimog fan (currently working on one 1:18 Implement carrier) I can say it is real beauty; such nice proportions, nice details very authentic colors, optimal propulsion solution, despite I'm more Technic fan, this one is really really impressive, even more that Porsche (IMHO)...
