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.

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:


42050 Drag Racer upgrade – inner details

As I don’t have the resources at the moment to create building instructions for this set and the changes are not that difficult, I think it is enough to share some detailed photos of the set without the body. I also took some photos of the two sets side-by-side to make the differences visible.

42050 Drag Racer upgrade – real wheelies!!

And finally, here is the second part of the 42050 Drag Racer video where you can see if the upgraded version can do real wheelies by itself (hint – it can 😉 )

The body panels and the stickers of the upgraded version are mostly coming from the 42041/8041 Race Truck, I think they fit perfectly.

Making of the BMW WR 1000 action shot

As many of you were curious how the motion effect of this series was made, let me show you some behind the scenes shots about it. The Rebrick contest allowed only 5 photos to be submitted, I wanted at least one of them to be really dynamic and to show the motorcycle in motion. I had some vague ideas at the beginning how this can be achieved, but with the help of some household items and leftover furniture pieces the following setup was born:
