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.
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!
Disclaimer – if you make a purchase of the parts/sets listed above on Ebay or Amazon then you’ll also contribute to my future Lego projects.
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.
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:
