The Ultimate 8043 S is the SBrick version of the Ultimate 8043.

The U-8043 is a fully motorized version of the original 8043 motorized excavator set.

The gearbox of the 8043 was removed, and all the digging functions, slewing and driving now all have their own PF-motor, allowing all the functions to be controlled simultainiously. And with SBrick, you can now even controll the speed of all the functions, making it a very precise machine.

With the help of Alez Zeimet (AFOL1969) and Strikeman, I've created full building instructions for the SBrick-version of the Ultimate 8043 Motorized excavator. Go to the instructions-page to get them.

It wasn't just a matter of exchanging the Power-functions with SBricks. Because of the different shape of the SBricks and the fact that there are 4 PF-connectors on top, the SBricks didn't fit. So I rebuilt the U-8043 and modified it so that 2 SBricks would fit neatly inside the model. And the profile I created for the Link Belt 250 X 3 excavator worked perfectly with this model as well.

    Frederic Ayrault page 115 I had to remove the frame 4540797 for this step
    It is also difficult to place all the wires of the motors and to power the sbricks

    Now I am waiting for the android app able to manage 2 sbricks but this model looks amazing
