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.
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:
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.
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:
I created a separate video with the following setup – 2 buggy motors + BuWizz + SBrick and controlled with an Android-compatible game controller through the great SBrickController app of imurvai – you can find the link to the app in this Eurobricks forum thread.
