Just in time for the occasion of the 40th anniversary of Lego Technic I built a scale model of Mercedes Zetros 2733. It is a 1:13,5 scale model of the Mercedes Zetros 2733 6×6. All functions are Full RC. It is 69 cm long, 21 cm wide and has a height of 27,5 cm. The weight is 4553 g. As battery I use the BuWizz. The Zetros is remote controlled by 4 Sbricks via iPhone.
Functions and used parts:
Propulsion:
4 Lego Technic Buggy Motor
Steering:
1 Lego PF Servo
Diff Locks (front / rear axles + central lock):
1 Lego PF Servo
4 Lego Pneumatic V1 + V2 1×5

2 Lego Pneumatic V2 Cylinder 1×11
Outriggers:

plus several Lego extension wires
Some more highlights:

All in all there are 13 RC controlled functions.
Update: As I just read on EuroBricks, LEGO® also wants to release a Zetros in the Technic series in summer 2021. The Zetros will have the LEGO® Technic set number 42129. I am very curious to see how LEGO® has realised my favourite truck.
I’m curious, I have always wondered how some of the MOC builders out there connect the wheels to the turntables.
Can you send me a picture?

Regarding: Mercedes Zetros 2733 – 6×6 – with Loader Crane
Hi, can you please provide instructions for this model? i will pay for them. Or I’ll buy the truck already built from you.
Hi Dimitri,
I thought about making instructions for the cabin and the hood so everybody can built it’s own Zetros. But as more and more people ask for I tend to say, maybe I’ll make full instructions fro a new Zetros. But first I have to find time to do so.
