Lego Technic 42078 Mack Anthem review updates and RC mod with SBrick

– Updates/correction of my review
– RC mod with Power Functions and SBrick

This is my first proof of concept RC mod of the 42078 Mack Anthem truck with Power Functions Servo motor and L motor, controlled via SBrick. I’ve also posted some updates and correction of my review published yesterday. I was informed via the comments how to properly operate the crane so I did a test again and apparently the whole structure is much more stable when the trailer is connected to the truck. As you can see I’m not an experienced crane operator or truck driver but I’m learning quickly 🙂



  1. will you have instructions on where to mount the motors and what parts might be needed to add the motors? I want to make this for my grand kids. I want to motorize the tuck and the trailer. Please let me know.

  2. HI Racing Brick,

    I’m given to understand that this model is not released yet. where did you get yours please. I’m thinking that this will be a great b’day present for my brother as he’s been driving them for 30yrs.

    Cheers from down under


    PS Cool mods with the RC functions

    • Glad you like the mod 🙂 I bought it in a toy shop in Hungary. Not sure where are you located, but in the US it is already available in some Toys R Us shops, and you can buy it in Germany as well in Metro and other shops. As I heard many shops does not list it online but you can buy it if you go there personally, so I suggest to call your local toy/Lego shop and ask them if or when they have it.

  3. I’m trying to find out from the video. I need to know what an SBrick is. I no that is how you connect the motors to it. I tried doing a search on Lego and can’t find the Sbrick. Can someone one tell me where to find it?

    • Dennis I already sent you an e-mail about SBrick. It’s really not that complicated, if you enter “sbrick” in google search, the first page is their webpage – You can find all the information you need there and also a webshop to buy it if you need it.

  4. Hello

    The set is released in belgium 12 januari

    Would be greate
    Sorry for my crappy Englisch

    • I’m not sure when will I have time to do a proper full RC mod for this set with instructions. If I do it it’ll be published on the page.

  5. Racingbrick,
    Did you use 1 L-Motor for turning the rear wheels and an L-Mortor for turning the motor. I was able to see how you did the L-Motor for the rear wheels. But when you build it as normal The drive is pass through for turning the engine and rear wheels. I was just wondering. O I did find the SBrick and will be getting at least one if not 2 of them. Will I need an SBrick for the trailer also? Please let me know.
    Thank you.

    • A single L motor drives the rear wheels and the fake engine as well. I created a new link from the fake engine to the rear that takes the drive. I’ll upload some additional images in a few days that will show you how I did that.

      • ok Thank you for doing that. I figure I should add the motors as I assemble it. Then I need to figure out how you did the server motor. Also did you remove the bed so you could add in the power pack? TY

  6. Hallo Rennziegel,
    habe Ende Januar von meinen Kinder den Truck zum Geburtstag geschenkt bekommen. Da ich IHN mit Fernbedienung haben möchte, suche ich verzweifelt nach Hinweisen oder Foto’s sprich Anleitungen oder Teileliste im Internet.

    Hat sich im letzten Monat in Sachen 42078 etwas getan ??? Wäre schön dass zu erfahren.
