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.
Can you spot the difference? 🙂 Full post with video coming tomorrow, check back! 😉
