Lego Technic 42078 Mack Anthem motorized & Christmas special

I would like to wish you all a Merry Christmas with this video and thank you for your support!

The Lego Technic 42078 Mack Anthem received additional rc functions with the lights and the motorized trailer, controlled by 2 SBricks. The light sequences of the container are also controlled by one of the SBricks. The trailer has 2 Power Functions L motors built in. Also tested with M motors but they could not handle the load. Please note that this is a test RC mod, so there won’t be any instructions for the time being. I’m planning to do a proper rc conversion and I’ll share that one in details.

The upgraded container interior is based on the following alternate build of 40223:


  1. ¿Tendrás instrucciones sobre dónde montar los motores y qué partes se podrían necesitar para agregar los motores? Quiero hacer esto para mis nietos. Quiero motorizar la tuck y el trailer. Por favor hagamelo saber.

  2. Hello. I am after some help with the 42078 Mack truck and the container lift. I have seen the upgrade mod to go fully R/C. I can not find instructions or a parts list and i see you said you would post a full set.


  3. Hi there! I
    n the reply above you said you could not create it. Does this mean it wil never be there? Or does it take a while?

    Really sweet build. Would love to rc mine as this one..
    Best of regards
