I received many questions and requests to provide details about this car, so I created this step-by-step assembly video and uploaded the part list to rebrickable.
Let me know if you build the car or something based on this version, I’m really curious how fast can you go with it 🙂
A brand new type of video from RacingBrick – stop motion brickfilm! 🙂 It’s a short teaser for my BuWizz powered Lego Technic RC speed record breaker. Join my little helpers to see the final tests for this beast and see the wheels spinning over 3000 RPM!
Since I received many requests again to provide instructions for the wheeled speed recorder Lego Technic 42069 Extreme Adventure RC mod, I try to help you and took a series of pictures while disassembling the model.
Please note that this video is far from being a complete guide – it shows how to build the 2 axles with the 4 buggy motors.
This is my third and last Lego 42069 Extreme Adventure remote control mod. After the Superleggera mod I did not plan to create another one but I was convinced by some comments on my YouTube channel (thanks for the tip!). Although I really liked 42069 on tracks, I realized that the top speed was limited by the construction so the 4 buggy motors could not show their full potential. I removed the tracks and added the wheels from the 9398 Crawler set.
The pickup-style body was kept from the previous mod to ensure the car is as light as possible. The axles were rebuilt completely to fit the buggy motors and the wheels.
Building instructions for my remote control mod of the 42033 + 42034 Extreme Off-Roader set using additional parts from 42035. Part inventory can be found on Rebrickable.
I’d like to share a small but agile creation – the remote control mod of the 42033 + 42034 Extreme Off-Roader combined set. Additional parts (mostly for steering) were used only from the set 42035 Mining truck.
The sets and Power Functions components are:
There are multiple options for the remote control:
For the video I used the 8878+SBrick combination as the control was easier with an USB gamepad through the SBrickcontroller app. It turned out to be a very fun little car, pretty quick considering the size. Enjoy the video!

Lego Technic 42037 Formula Off-Roader upgraded for full remote control. Engine swapped, it has a V8 now. Driven by two buggy motors, powered by 2 BuWizz units. Steering with Power Functions Servo motor. Engine powered independently with a Power Functions M motor. Installed Power Functions Lights as well.

After my first RC mod of the 42069 set I wanted to build something faster 🙂 The plan was fairly simple – remove every non-vital part (including the fake V8, sorry), streamline the body as well, finally add 4 buggy motors and 2 BuWizz units. The result is pretty fast considering the size and the tracked wheels, check out the video:
Originally I did not plan to create any building instructions for this mod as the motorization was an ad-hoc process, tried to replace the manual parts while keeping the original structure as intact as possible. Since I received so many requests to provide instructions, I try to help you and took a series of pictures while disassembling the model. Please note that this video is far from being a complete guide – it shows how to build the 2 axles and provides some additional hints on the placement of the M motors.
If you’re looking for 3d files or additional ideas to motorize this set, I suggest you to check this topic on Eurobricks, it already has some great content and I’m sure it will have more.
