How to build ?

📕 You only need the parts and the instructions. You can purchase the PDF instructions on this shop (all versions included) and build with your own parts (you can build the manual version, then upgraded later by adding the motors and battery/remote). The Rebrickable inventory included the parts to build all versions so with spare for the manual one). See the end preview below to see the difference.

🎁 If you want to purchase the LEGO parts + PDF instructions, have a look to my creator page or request a quote from :

⚡ For motorized version : In addition of the motor (PFS or C+), the model can have different remote controlled solution :

  • In Power Functions System : 1x BuWizz 2.0 and a compatible smartphone (PDF tutorial included), or a generic PFS 2.4ghz Battery Emitter and Receiver (Cada, Mouldking or other Chinese brand) or legacy PFS infrared system (8881+58123a+8885)
  • In Control+ system : 1x Control+ Hub (ref 22127 or 85824) (PDF tutorial included) or 1x Buwizz 3.0 with compatible smartphone (PDF tutorial not included, on request)
  • If you want to build only the Truck in motorized / manual version, or the trailer only, here are the Bill Of Material :

All instructions variations (PFS, Control+, Manual) are included in one purchase.

👍 Thanks to TechnicMOCer for his axle trailer system who inspire me to make my own version which is basically an improvement over his one.
