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.
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.
The Lego 42065 RC Tracked Racer is a pretty cool set. You get remote control capabilities out of the box – all Power Functions components are there for some real RC fun. There were some previous RC Technic sets produced by Lego, but they had a much higher price tag.
