I ended up trying something different to my unimog's drive line cause i was getting tired of blowing out ujoints with my extremely low geared setup so I tinkered about an made the crawler axles work for the unimog without have to do anything major to the chassi besides move a few braces back for quad steer an adding liftarms for holding balljoints in place.

Was successful at getting it all to work without wheel rubbing an keeping the ride hight from going being to outrageous. Speed its slower then the crawler due to weight an it being driven by M motors instead of L motors but that will change when the motors are available.

It was probably the huge power-puller tires that were making the drive require so much torque and snap the ujoints.

you woulda thought but the grippy 94mm tires had a habit of blowing ujoints out as well ;x but the power pullers look a lil better to the eyes to me with the ride hight with the different axles.

I wonder what would be a better drive option for the Unimog

- A XL-motor without reduction

- A L-motor with reduction (1:3 or 1:5)

[Korni]

I used a XL-motor without any reduction but I´m planing to use the XL with a reduction

Korni you can use Easy Thumbnails to resize your photo's

Dluders thanks for the tip

Or he could use "Windows Live Photo Gallery" and on the ribbon, in the organize area. Select properties and there is option to save a the image at reduced/small sizes.

Pat, if you don't mind, would you provide me with ldd-file for your trailer?

Thx,

Jörg

Nice! - Then it just a shame that unimog doesn't have a dedicated epto(as electrial power take off) plug in the back.

On the topic of motorizeding it i am also thinking a about, doing i with a few pf-l motor for drive and a servo from the crawler, if I get that set for myself as extra birthday present. Like last year where I got myself the 8110.

[Pat-Ard]

I like the idea of the EPTO... Does parts like these exist?

Would be great with the trailer...

EPTO would be made using an PF extension cable and connecting it to a beam on the back, not the best idea but it would work. I would rather have a pf stud connector-plug connector, where it would connect to the battery box but it can also go through a pinhole, then make the male/female connectors for it.

Has anybody seen this video?

Has anybody seen this video?

That is an awesome video! It explains exactly what is wrong and how to fix it .

And to think, all this time Lego has lied to me about steering and suspension

[Korni]

A good video!

And it´s much better for RC, too.

[jacobkristensen]

Yeah it seems to be a great, a great improvement. I am for sure gonna try this late on in the summer on my mog. Also I am looking into to maybe motorized with pf-l and pf-sv motors if I get myself the crawler af a late birthday present.

Oh and btw. are there anybody that knows if there exits a 3d file of the 8110 as it directly from lego, because the I am maybe will try and mod that file few of the best improvements to unimog.

Hi,

just take a look at post #983in this thread.

So far

Fantastic link! I really appreciate when the explanation is as informative as the building steps.

[andythenorth]

From the LPE video: "all this makes the Unimog, otherwise an excellent model, not fun to play with. If you own one, this is not news to you"

Out of the box the mog is not very playable, which is a shame. It fails the toddler test, and also the casual visitor "what's that thing on the shelf do?" test.

Video inspires me to mod mine. Which is good, modding is fun :)

[TimH]

Great video!

[Xan326]

I went to the video on Youtube and downloaded the instructions. Its a bunch of Quicktime pictures, does anybody have a pdf version?

I am slowly (when I have a few minute here or there) putting this together in LDD. Once I get that done, I intend to e-mail the original creator and see if they care if I share it.

[Xan326]

@yotogi

Hopefully LDD will be helpful to me for once, I usually have absolutely no luck with digital builders, either they don't have a piece or I can't figure out how to use them. But best of luck!

Fantastic video HOWEVER.....

.....whilst I am a huge fan of this man and what he does, I do have one tiny bone to pick. He says that Lego is teaching kids wrong when it come to suspention with the unimog, which may be true in many ways (like the pivot point being far outside the wheel). However whilst the geometry is all wrong and could be greatly improved it is still mechanicly closer to real life than this modified version. A real unimog does not have multi link suspention and I appreciate it when Lego invests in new parts in order to make things more life like, like they have done with the Unimog. However I am not letting Lego off the hook that easily . Whilst his solution to the steering problems are incorrect by his own standards in that they are not life like, they do highlight the fact that there ARE problems and that, despite the fact that the unimog is probably the best technic set ever released, it is still not perfect due to the geometry problems. It always seems to be that Lego comes soooo close to perfection but never quite gets there even tho they easily could have. They could have made it perfect had they designed the parts a bit differently, They could have made the hubs much deeper (like real life) to allow a slightly different portal gearbox to fit much further into the wheel. They could have made the hubs black (never seen grey hubs on a real Unimog). They could have made the tyre tread like the cevron pattern on the real tyre, and all with no extra cost as it's not more, just different. It's infuriating sometimes that they seem to keep doing things like that!

Good video,I have motorized mine.

Too be honest I am not bothered about fixing some of the problems my self.

[Pat-Ard]

Have you a LDD file for this amazing creation?

It would be great because I´d like to build this one.

Greats

Hi The-Game,

did you complete your version?

So Far

I agree, but the more specific the parts are, the less possible for lego to use them in other sets. Maybe those wheels look great on a Unimog but not necessarily on a supercar. I think that's the main drive behind their decisions, to make sets that are as close as possible to the original yet its parts are completely interchangeable and usable to make virtually anything.
