Fastest Lego Technic 42069 RC mod with wheels & 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.

Mercedes AMG F1 W14 Speed Champions digital moc

Lego has organized recently another Rebrick contest with the Mercedes AMG Petronas F1 Team – the goal was to create the F1 car of the future. I wanted to create a car that looks somehow futuristic but looks like an evolution of the current cars, and represents the color scheme and the logos of the team. As I do not have too many non-Technic bricks I decided to create a digital entry. I started to build with LDCad, that’s the application I’m more or less familiar with. I started to sketch some ideas but the summer holidays came so I forgot about it. I only realized the deadline 3-4 days before it arrived, so I had to act quickly 🙂 I finished the build in LDCad, but as it does not offer any rendering abilities I had to look quickly for a solution. The Ldraw-Povray connnection was not that easy to figure out in such a short time frame, so I had to look for something else. I considered rebuilding my car in Lego Digital Designer as there are multiple good rendering options for the official app, but unfortunately I used some pieces that are not available in LDD.

Lego Technic 42033 + 42034 + 42035 3-in-1 RC mod

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 42069 Superleggera RC mod – buggy motors & BuWizz

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:


Lego Technic 42069 rc mod partial building instructions

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.


Roads? Where we’re going, we don’t need roads.

I don’t think 42069 would need a wheel swap to look cool, you just need to find the terrain where rubber won’t work 🙂 Ideal vehicle to explore Mustafar 🙂

I re-used the scene built for the Star Wars motors, 42069 fits here perfectly.
