Lego Technic 42069 RC mod with Power Functions and SBrick

After building the 42069 Extreme Adventure set the next challenge was to motorize it. Luckily the set has a spacious internal structure, it is pretty easy to squeeze in several Power Functions components. The aim was to add the Power Functions parts without taking apart the set completely or to change the original structure, so obviously there are more elegant ways to hide all the motors and to upgrade the suspension and the drive train. The list of the added elements:

4 PF L motors (drive)
1 PF Servo motor (steering)
3 PF M motors (functions)
1 PF switch
2 8878 Battery boxes
4 PF lights
2 SBricks

The performance of the car is pretty ok, it can drive on grass and gravel as well. I was expecting a little bit more with the direct drive of the 4 L motors, but the weight increased as well significantly with all the added components. I’m not planning to create any instructions, but here are some more photos of the mod, it will help you to create your own version:




  1. 你好,我很喜歡你的作品,可以教我如何改裝跟你一樣嗎?

    • Hi! If you check the pictures in the you should be able to see the main modifications made on the set. I’ll probably post some more pictures later when I disassemble the set.

      • 因為我接觸lego 不多,偶然間看到你的作品讓我非常喜歡,你的圖片可能有人知道怎麼去改裝,但我不是很清楚知道要如何做~

        • I can suggest you to practice then – start to build official sets, check how they work, how they are structured. Once you are familiar with the main concepts then you can start to modify them, add Power Functions, change parts etc.

          • 感謝你的建議,我會去瞭解零件的構造後,再來改裝看看,畢竟動腦本身就有很多的樂趣

  2. Good luck and have fun! 🙂

  3. Did you use a transmitter

  4. where can download the sbrick profile???

    your mod is very very great

    thank you for share

  5. Why do you need 2 sbricks

    • There are 8 motors and several lights in the model. Even with the 8 outputs of the 2 SBricks I had to couple 2 motors (the reason why I had to include the PF switch as well) to be able to control everything properly.

  6. Will a transmitter and a controller work the the same

    • If you’re talking about the Power Functions IR receiver & controller, then yes, it can work. But you’ll need 4 IR receivers to be able to control everything – remember you need 8 ports if you want all the functions motorized what I had.

  7. Please can you list the items I need for it to be controlled via controller

    • Instead of 2 SBricks you need 4 Power Functions IR receivers (8884). You’ll also need at least 2 Power Functions IR remotes (8885).

  8. do i need a long cabal to reach the ir receivers.

  9. could i have the controller 8879 in stead
