Hey Guys, here is the preliminary instruction for the Dakar truck. Don't mind the coulours, use what you have in stock. This thing is made to be colorful

The body is connected to the frame with only two Pins. So the removing should be easy.

Wow! Thanks for sharing the instruction!! 👍👍😊

How much slack you have with steering? Is it better to use reingorced new CV joints than classic universal joints (less slack)?

Thanks for instructions; it is always nice to se something that could give some idea...

[efferman]

Reinforced cv joints are always better when they fit in the given Space.

Well that is another problem, but I have some ideas...for tomorrow; at least I have smooth drive with enough amount of torque (2 x XL motors...)

[jorgeopesi]

Thanks for the instructions I do not have the motors but I will see your work to learn something.

[efferman]

The final instruction will come tomorrow on rebrickable.

this one is version 2 with a different aproach

 

[1gor]

It looks strong (despite small climbing distance), but question us how strong is drive with cada motors, compared to double powerfuncions XL motors (since you have experience with tjem in uour Scania and M.A.N.)?

[efferman]

Set to the same rpm on the wheels, the Buggys are much stronger.

[1gor]

Question is how much? Twice? Can one buggy motor replace 2 XL motors?

I Think so.

Based on sariel's gear calculator it is bit better to have one buggy motor than 2 XL notors, but Lego one have their issues, they don't want to respond at all from time to time (directly to battety box they work perfectly) over Lego receivers.

[efferman]

Forget the lego buggys. They are rare and super expensive. There are enough affordable Alternatives out there.

The promissed instruction is online.

I have one buggy motor ftom 8421 set that I try to use in one of my creations...Yesterday I had a bit time to play with receivers and receiver from 42095 works perfect with buggy motor and only thing that I have is to solve steering with M-motor...

I had an Idea for compact portal hub which fits in 62.4 tires. so I have built a small chassis for it.

 Video is to fast for my old eyes, so I cant see anything...but I'm all ears...this is something that I look how to make for ladt couple of years for my Unimog

Well, indeed, not much is visible on the video.. Any more details?

[efferman]

The chassis itself is nothing special, but the wheelhubs are a little bit strange. The Rims have an 25 tooth inner gearing which is driven by a 8 tooth gear.

The pivot point is close to the wheel.

It is s bit unusual indeed...

Perhaps it us time for Lego to make narrow 2L differential; but fur that new bevel gears will be needed...

Nice effort Micha.
